Your not running @ defaults speed there bro..3-4-4-8 is spd..thats why your getting the errors running memtest86..ill run it also to see what happens with my timmings @ default...Oh btw citation..i am running the adata chips..:) i checked last night...:)


Same as you..

My SPD is 8-3-3-3, which is what it selects when I set it to SPD select. When I manually set it to 8-4-4-3, the memory errors go away. I just talked to Bill at Komusa. He initially told me the timings were 8-3-3-3, but changed to 8-4-4-3 when I told him I was getting memory errors at 8-3-3-3. He says it's normal for the heatsink to fit with an air gap because I've got the 256M module which doesn't have memory on both sides of the board. This sucks IMO. He offered to exchange and guarantee I will receive ADATA chips, but he's going to charge me 15% restocking fee. This also stinks IMO. I'll probably return the memory and eat the 15% restocking fee. Not very good customer service IMO.

[GWAR]

Man i hear you..i was a little fishy also talkin to bill .cant understand half of what he says..:lol..Im happy with mine though..im oc @ 160 1:1 on my 2.4c @ 24c ..I wonder what we could gain , if we returned them? Unless you want to spend another 100.00 bucks for ocz and get the same results...but..i do hear what your saying..i told bill i was ****ed becuse it wasnt what we thought we ordered. other than that, i was very happy with the ram... he said they test and test every chip to the fullist for stablity and o/c..yea yea i was thinking ..:) anyways good luck, and post your results on your next purshase..

[Skoob]

Check out the new Corsair PRO chips

http://www.corsairmicro.com/corsair/xms_proseries.html

I want some.

[GWAR]

Yea i seen those...sweet i think...i do wonder how they perform though..? im sure kickass..I do wish ,corsair would put lds read-out of the chips temps on the memory ..:)

[Citation4444]

Well, I've ordered the ADATA chips on 1G of this memory, and have an RMA number to return the ones I've got for credit. I'll let you know how it goes. By the way, I tried my existing memory at 250MHz with 8-4-4-3 timings on memtest86 overnight and it generated many errors. Since I am overclocking my 2.4C I cannot be sure it's the memory, but there's no way to run the memory at 250 and the cpu at 200 with this board - at least as far as I can tell.

I'll let you know the results as soon as I get the new memory.

[Angry_Games]

mine just does not seem to like HyperX PC3500...it will run at stock speeds just fine, but any overclocking seems to just fail instantly in Prime, or cause a CMOS clear heh. Ive tried ever dratted setting I can think of...wierd because it overclocks nice in the NF2 board heh.

im keepin my eye open for a good deal on PC4000...

[Citation4444]

I notice there is a new LanParty 875ProB. How is it different from my LanParty 875Pro? I see it takes a different bios. Will that new bios work on the 875Pro?

[Angry_Games]

both the NF2 and I875 have "B" revisions hitting the market very soon.

I also forgot to post this to you guys:

Hayward, CA (September 17, 2003) - DFIâ, the worldwide leader in performance and corporate motherboard manufacturing, today announced the unveiling of a new line of motherboards at Computex, the INFINITYâ series, aiming at performance users on a budget. Leveraging DFI's expertise in motherboard design and the popularity of the LANParty series, the INFINITY is created with the most discerning overclockers and hardware enthusiasts in mind who demand best price/performance.



Available in both the Intelâ and the AMDâ platforms, DFI will offer three INFINITY models at launch: 875 INFINITY, 865PE INFINITY and NFII Ultra INFINITY. Taking advantage of what the latest chipsets have to offer and incorporating the groundbreaking CMOS Reloadedâ overclocking utility and Super PATCHâ performance enhancer, the INFINITY series delivers exceptional stability and power every overclocker values.



Based on the signature crimson red PCB, the INFINITY series is equipped with advanced features important to the target audience: blazing fast dual channel DDR400 support, Serial ATA RAID, patented RAID 1.5, 6-channel audio, Gigabit LAN and high speed Firewire. To complement the LANParty series featuring the industry's first UV sensitive slots and sockets for case modders, the INFINITY series aims to deliver nothing but a stunning PC experience.



For the Intel Pentium 4 platform, overclockers now have two compelling choices to satisfy their need to "tweak". The 875 INFINITY is based on the Intel 875P/ICH5R chipset, and supports Hyper-Threading, Performance Acceleration Technology (PAT), dual channel DDR400 up to 4GB, 6-channel audio, Intel CSA Gigabit LAN, 2 Serial ATA IDE, Serial and ATA133 RAID, and proprietary RAID 1.5. The 865PE INFINITY is based on the 865PE/ICH5 chipset and equipped with support for 4 Serial ATA IDE ports, Serial ATA RAID, and IEEE 1394 Firewire. Extending the lead in designing motherboards for the enthusiasts, the 865PE INFINITY is the first to feature DFI's new Super PATCHâ technology. Leveraging the advanced features the Intel i865PE chipset offers, Super PATCH enables the INFINITY model to deliver supreme performance gain over competition in benchmarking software including 3Dmark2001SE, PC Mark 2002, and Comanche 4.0. For the AMD fans, the NFII Ultra INFINITY is based on the popular nForce2 Ultra 400/MCP-T chipset and supports dual DDR400 up to 3GB, 6-channel audio, LAN, IEEE 1394 Firewire and the newest 4 Serial ATA IDE ports that provide SATA RAID 0/1/0+1.



Setting the INFINITY series apart from the rest of the competition in the overclocking arena is the incorporation of the CMOS Reloaded overclocking utility. CMOS Reloaded enables the users to BACKUP their overclocking configurations under a user-defined name, LOAD the previously saved configurations based on the applications, and RENAME a configuration setting. With allowance of up to 4 sets of configurations per computer and the ability to attach different operating systems to each set, this revolutionary technology enables the users to take overclocking to a new height.



The INFINITY series is currently available through DFI's authorized resellers, distributors, retailers and e-commerce partners. For more information on the new series, please visit http://www.dfi.com <http://www.dfi.com/> or email PR@DFIweb.com.

I got my new Adata PC4000 RAM today from Komusa. So far I'm pleased. It will do 265MHz 1:1 with dual 512MB modules installed. That's as far as I've got in testing it, but that's pretty good. Interesting enough, it arrived without copper heatsinks - just the memory module. It has 4ns Adata chips on it. Here are my CPU-Z screenshots. What do you think?

Cit...simply awesome! Linking to others in my AMDMB forums to see this so they wont call me a liar hehe

[GWAR]

Sup bros...Well i got a abit max3 today,to replace my lanparty875..man, i was getting the cold boot problem,having to keep taking the battery out..and on sunday i was listening to nascar live from the pc and all of a sudden the pc just shut-off and never turned back on..i tested everything in the pc im typing on..all mem and 9700 and cpu worked, so it had to be the m/b..i loved that lanparty board, but i cant be hasseled with the power problem..I..was having with it..So @ least now ill test the adata pc4000 with a 3.2 voltage..:)..ill post some results later..peace..

right on Citation4444!!! so you like them better than the infinion4000?

[Citation4444]

I hate to see you go away from the LanParty, but I can understand your reasoning. They need to come out with a way to increase the DIMM voltage beyond 2.7v or they will not compete in the overclocker market due to that reason alone.

[Angry_Games]

LanParty "B" revision is out... =) (I875)

[GWAR]

Check this out bros...Crazy ....max3... this is with your old mem cit4444..:)

[Citation4444]

Awesome GWAR. What DIMM voltage did it take to do 1:1 at 291MHz?? That's incredible.
I'm going to wait for the next BIOS revision with my LanParty875Pro. If they don't fix this voltage limitation, I'm moving on.

[Clevor]

Anybody know where we can get the 'B' revision of the 875CW board?

[Skoob]

Citation, Angry has already confirmed that the engineers cannot fix the voltage problem with a BIOS fix. It is a hardware issue.


IS anyone using the 875B BIOS 8/28/03 on their rev A board? I don't want to be the guinea pig again.

[Angry_Games]

I apologize to all that are waiting for answers. I've experienced a death in the immediate family this week and will not be around until the end of the weekend or maybe Monday.

I apologize to all those expecting answers from me. Please be patient, and if it is an immediate need, please email tech@dfiweb.com with your questions/issues until I return.

Thank you,

Travis H.

[Citation4444]

Sorry to hear that, Angry. Take your time and be with your family. We'll be here when you get back.

I might be the guinea pig and try the "B" bios in my A board. Wish me luck. :)

[Skoob]

Angry, I am sorry to hear that as well.

Citation, if you can find a modification that would be great. Angry did mention that people are doing it on the nf2 board, maybe it will be somewhat similar.

I wish you luck on the bIOS as well:D I hope it works and is worthwhile.

[Citation4444]

It wouldn't let me flash to the B bios. Gave a message: program file's part number does not match with your system. Drats.

I did a voltage mod on my Asus A7N8X Deluxe mb. It was pretty hard to do because of the small points you had to solder to. Before I investigate this, I'll wait to see if the rev B board has addressed this voltage issue. If it has, I'll either upgrade to it or buy an Abit Max3 like GWAR's got. :D

[Skoob]

Yeah, Im kind of heading towards max3 as well. Only thing holding me back is the lack of ide RAID.

[Angry_Games]

hi again. I am able to get the parts info you need if you wish to voltage mod the board. You must realize that this will instantly void any warranty =).

some guys at the AMDMB forum were wanting to vmod the NF2 LanParty and the lab in Taiwan gave me the exact specs and parts used so I assume they would be able to give the same info for the I875 LanParty.

Citation: I am assuming that they have resolved the vdimm voltage on this issue of the board. I am waiting for my "B" revisions to show up so that I can give an honest answer as to 'what has changed that is IMPORTANT' instead of making you read a document that just lists all the details and you have to decipher yourself what is and isnt changed.

I have some great Buffalo and Golden Dragon RAM that beg to be volted to the max waiting to go in it when it arrives. Me and my buddy John have been all over the LP I875 (we must have tested 7 different types of RAM in it so far), and it has stayed at a certain speed only about 2 days at a time (today it is up only to 3.075Ghz, Monday it was at 3.42Ghz, etc).

Because of the situation I am in, i still might not get back here to posting daily until Monday, but again, if you have any issues or questions you can catch me at travis at dfiweb dot com. *ill get it in my sig soon dont worry*

Thanks

Travis

[Citation4444]

Hi again Angry_Games

I would love to have the mod circuit details on the LanParty 875Pro. I would love to keep this board, because the only thing I don't like about it is the DIMM voltage range offered. If I could fix that through a modification of the board, I'd do it in a heartbeat. I don't care about voiding the warranty. :)

[Angry_Games]

lemme see what the head nerd says =)

[Skoob]

Count me in for the VDIMM mod. Please post EXACTLY what to do.

[Angry_Games]

well they wont give me that info heh...they will tell me which regulators are being used and can most likely be modified. I have not heard anything from the NF2 mod guys if they were successful or have even tried yet, but I have been away a bit also.

I probably wont hear a response from the Taiwan lab until late Sunday night (monday for them I think).

I'll keep you posted and get as much info as I can for you, but I also know that you guys will have to know pretty much what parts you will need to mod so I can get exact info on them if possible =)

Travis

[Angry_Games]

Travis,

It is Intercil TSL6520 for Vdimm voltage regulator on LP Pro875 board.

Best,

Tom

let me know if you need more information, but again, try to have an idea of how to do this already so you can ask for exact things you need (the engineers are not real keen on ppl modding their boards lol)

[Citation4444]

Thanks for that info. It's Intersil, not Intercil. And the part number is ISL6520, not TSL6520. That is the DC-DC switching controller used to regulate the 5V down to 3.3V (usually). The info we need is the location and value of the resistors used to determine the output voltage. If they're following the reference design (according to Intersil Application Note AN9932), it would be R1 and R4. According to that AN, the output voltage is approximately 0.8(1+R1/R4).
Hopefully, the engineers will provide a little more information.
:)

[Angry_Games]

heh good i copied your entire post and am sending it to Tom. I hope being Chinese (Taiwan) he understands what you are meaning. If not, I'll see if one of the DFI guys/gals in San Jose might be able to explain it better to him =)

T

[Angry_Games]

hey guys, i just came into some cashola...and want some of this awesome PC4000/PC4200.

can you guys link me to a reliable lowest price site that you are finding this on?

I've a couple posts into my AMDMB Trading forum for some Buffalo/TwinMOS stuff, but since you guys have already messed with it and know what to get, I'd trust you all to lead me in the right direction =)

yes i could bug the DFI lab for some, but they dont have anything higher than PC3500 at this time lol.

Thanks!
Travis (still waiting for the Taiwan lab to answer btw)

[Citation4444]

I bought mine HERE (http://www.komusa.com/index.html) . Remember I had to return my first batch and got them to commit to ADATA chips for the replacement. I'm satisfied with the memory I now have, but I'm somewhat reluctant to recommend them as a vendor because of my experience.

[Angry_Games]

hrmm...i hate to say it...but that place looks kinda chintzy...no real description on the modules other than they are 500Mhz DDR, and for $10 more you can get a brand name? lol.

one of the memory guys over in AMDMB trying to get ahold of some TwinMOS 4000. He sells all the other types of TwinMOS, BH-5, CH-5, TMD, etc.

[Skoob]

Personally I would go for some OCZ EL dual channel Gold PC 4000 or the new 4200 is coming out very soon. Not a money saver at $400 though.

[Angry_Games]

buffalo got some new 4200 out, and my guy in amdmb got some twinmos 4000 finally...seems like this is the big tide-over until cpu's start ramping back up eh? =)

[Mikes95XLT]

Alright guys I still can't figure out how to attach the front USB ports on my Chieftec Dragon case. There are 4 plugs, all labeled:

+5V (red wire)
-D (white wire)
+D (green wire)

Ground (black)

+5V (orange wire)
-D (yellow wire)
+D (purple wire)

Ground (black)
Ground (brown)

I can't put them in any configuration that works. Can you help me out? I've read the mobo book, still can't figure it out.

Thanks!

[Angry_Games]

mike im right in the middle of a giant networking job but if yer patient, ill be back around 9-ish MST USA and I'll walk ya through it.

Once you set them, you will know how to do them for ALL USB connections like this, as they are universal and I've yet to see a different config on boards =)

Travis

PS: got the I875 "B" today mwahaha. And 1GB of Corsair TwinX 6-2-2-2 =)

be putting it together tonight or tomorrow with a P4 2.4C 800FSB/HT!

[Clevor]

Can you confirm the 'B' board has VDIMM options in the BIOS higher than the 'A' board??? If so, where can you get the 'B' board?

[Angry_Games]

cant confirm until i get her put together =)

looks like tonight since a customer bought my Barton 2500 thats in my DFI NF2 LanParty....got no choice now heh

[Mikes95XLT]

Sure take your time. Thanks. :)

[Angry_Games]

Mike I apologize once again, its 5:40AM and I have not even eaten but at about 2pm this afternoon. Just got the I875B up and running, still working on others behind me. Going to bed now lol. But I PROMISE (these guys will tell you im pretty good about promising...just have to remind me sometimes!) I will walk you through it. The I875 manual is incorrect on how to do the USB.

Look at the USB header pins on the board. one set of pins has 5, one has 4. At the front (where there are two pins side by side), that is where your VCC (usually red) goes for both. The next pin is for DATA- (usually white), then the next pin is DATA+ (usually green), and the 4th pin is Ground. You will have one extra pin that is not being used (or its a 3rd ground...my Chieftech case has the 3rd ground, none of my other's do so there's always a bare pin).

If this is nonsense and you dont understand, have no fear, I'll cut a proper diagram when I get up =)

if you have USB headers on any other board, just look at them. They are all standard in how they connect. Its just an error in the I875 manual/setup sheet as I followed it too and thought the whole time "bs, this can't be right!" and blammo, it wasnt. So I hooked em up like all the other USB headers I have ever had to hook up, and they worked =)

T

PS: I875 "B" unfortunately only vdimm's to 2.9v =/

[Mikes95XLT]

I kinda understand. But a diagram would be really awesome, I would really much appreciate it. Take your time, I'm in no rush. I have to work this morning 'til about 4pm (Central time US) so I'll check back with ya later. Thanks a ton!

[Angry_Games]

http://www.angrygames.com/pics/usb_header.jpg

the Grey lines are actually supposed to be WHITE but white on white... heh

let me know if you need more help =)

Travis

[Mikes95XLT]

Travis you're the man! It works perfectly! Thanks a ton!! :D

[Clevor]

PS: I875 "B" unfortunately only vdimm's to 2.9v =/

Hey Angry, know anything about the DFI Infinity? What is the VDIMM limit on that board? I'd be happy with 2.9 these days.

I got a steal on the board as a store in Japan was liquidating the last one. Got it for $108 U.S. It's an 875P/ICH5R with SATA RAID and HPT372N, so it enables IDE RAID 1.5 with just two IDE drives. Has Gig lan too. Tell me it isn't a Lan Party with just one LAN, which is fine with me. :clap: It's a Rev. A board though.

[Angry_Games]

the Infinity I875 (my server's board heh) only does 2.7vdimm. Witha 2Ghz "A" P4, it will max overclock to 2.65Ghz without a hitch =)

have yet to put a 'real' p4 in it ;)

but its basically a LanParty without the pretty colors. The LanParty only has a single giga-lan port like the Infinity (both A & B LP's which I have running currently).

[Clevor]

After reading this whole thread, I guessed it only has 2.7 VDIMM. 2.7 won't get BH-5 very high, although I do have different brands of PC4000 to try on it (OCZ Gold/ADATA/CFD). Oh well. I'll see how high it will overclock the CPU, and how bandwidth compares to other boards I've used.

I think a VDIMM mod is easy on the board but it would have to attract the likes of the Extreme forum crowd, which hasn't happened yet.

[Angry_Games]

PC4000/4200 doesnt need more voltage if you get the right sticks =)

this is buffalo PC3200 @ 2.8v / +50mv vcore / STOCK TIMINGS! (CH-5 chips)

oops sorry CIT, have not heard back from anyone in Taiwan in a long time =/

guess I should get on the ball eh?

still want more specific info on that v-mod?

still want more specific info on that v-mod? Yes, I would like some more information about voltage modifications that can be made to the 875Pro. I have been enjoying the board even so, but the voltage mod would make it so much sweeter. :D

[Angry_Games]

heh, np. I'll try to get more info. Seems like the engineers are not keen about giving that up (scratchin head).

[Clevor]

I have installed my DFI 875P Infinity board. This board definitely rocks! I have tested about eight SD/CW boards and this is one of the highest overclocking boards I've seen. VCORE is very strong and works, I think up to 1.85.

I have an L310xxx Malay 2.40C that maxed out at 287 fsb at 1.62 VCORE on the P4C800-E. I made it to 283 at 1.49 volts before I had to pull the chip to check out an MO stepping (will sell it this weekend if it's a dud). Well the MO is doing 285 at 1.54 volts, and haven't tested more VCORE. The same CPU errored out at 279 fsb at 1.58 volts on the 4PCA3+.

Only caveat is the 2.7 VDIMM, so my ADATA PC4000 maxes out at 270, 1:1. At 285 I have to run 5:4 at 2.5-4-3-5. If I had 2.8-2.9 volts I could do 1:1.

Also, the board does not like BH-5. Board is 3D unstable at all mem ratios, even though Memtest is clean. I've seen the same problem on the Gigabyte, Abit, AOpen, and MSI boards so I plan to contact Corsair on this. But it loves Hynix or Samsung PC4000.

PAT is enabled at all mem ratios with no BIOS tweaks! I have not seen any board do this. The P4C800-E and Epox board needs BIOs tweaks to show it as enabled.

With a VDIMM mod, this board will rule! I think even at 2.9 volts. I believe the VDIMM mod is the same as on the Albatron PX845PEV Pro. There is a chip with 5 legs near the DIMM slots and all you do is hook up a resister pot to it. But I'm not brave enough to try it.

I have a HW monitor for my Epox board that shows VAGP and VDIMM. I will try to install it on the DFI to see if it reads these voltages. Both boards use the Winbond chip for HW monitoring. But 2.9 VDIMM might be enough for most people (if you get the Rev. 'B' Pro board).

[Angry_Games]

use the hardware doctor on the 875P cd.

the "B" LanParty I875 has 2.9vdimm, and its pushing my pc3200 CH-5 Buf very nicely so far. I do have some Buf PC4200 on the way...

and the kicker...even though this is an Intel thread...the "B" NF2 will have 2.6v - 3.2v vdimm =)

[Clevor]

use the hardware doctor on the 875P cd.

You mean the one on the 875Pro? The one on my 875P Infinity CD does not show VDIMM or VAGP. Can I download that on the web site?

I notice from the Newegg pics, my Infinity board has a slightly different mosfet arrangement from the 875Pro. I see two small aluminum caps on mine, which is very strange as I have never seen such mosfet caps used on any board. The Pro has the traditional all resin caps. Otherwise the board layout looks the same.

I am using the 6-03 BIOS. I was worried about the 255 fsb BIOs limitation but nope, this one goes to 400. I'll install the latest July BIOS tonight.

I was running DDR440, 2-3-2-5 at 2.7 VDIMM on my XMS3500, until I tried 3D: not stable. Memtest clean though. Seen the exact same problem on all the boards I tried except the Epox and Asus. And not just at 5:4 too but 3:2. The boards don't seem to like high performance ram. This ram has gone 250, 1:1, 2-2-2-5 at 3.2 volts on the 4PCA3+.

[Clevor]

I made it to 283 at 1.49 volts before I had to pull the chip to check out an MO stepping (will sell it this weekend if it's a dud). Well the MO is doing 285 at 1.54 volts, and haven't tested more VCORE. The same CPU errored out at 279 fsb at 1.58 volts on the 4PCA3+.

Well that L310xxx Malay is now doing 290 fsb or 3.48 gig stable on the DFI 875P Infinity board. It actually benches 3D fine at 292 or 3.5 gig, but won't pass Sandra Multimedia until I drop down to 290. The only other board that came close to this overclock is an Asus P4C800-E, which did 287.

I have another 3312xxx CR 2.40C that is 2 mhz better than this one, so pencil in that one at 3.5 gig.

And that MO stepping 2.40C did 292 or 3.5 gig thoroughly stable at 2D/3D on the board, before I pulled it to test the L310xxx Malay. It could possibly go higher. I had it at 1.60-1.62 volts.

All the overclocks were tested to be 3D stable with a plethora of 3D stress apps like the Serious Sam 2nd Enc. and IL-2 Sturmovik demo loops, in addition to 3DMark2001/2003, CodeCreatures, etc.

Hey, is ANYBODY running 5:4 stable on this board? I found ADATA PC450 is the only ram it really likes, but it is only stable at 1:1 and 3:2, which is where I am right now at 292 fsb. Still, at DDR388 and 2-3-3-6, I get 2800 unbuffered, and I'll take it with the 290 fsb and 3.48 gig.

[Clevor]

Did more testing on the 875P Infinity. Getting lukewarm now. When I run a 9800 Pro or Geforce 5900FX, I have to drop the fsb way down to 283-287 to be 3D stable. Yet a Ti 500 card benches 3D fine at 292 or 3.5 gig! With the latest cards, the computer will reboot while running 3D or lockup until I drop down 8-10 mhz. Usually I only have to drop down 2-3 mhz from my Memtest clean setting to be 3D stable. Memtest is clean at 294 fsb and I can run the long SuperPI run at 292!

So the board is CPU/memory stable at very high fsb, but the AGP slot is not putting out enough volts to keep up with the overclock. I tried 1.6 VAGP and no help. Not sure what's going on.

Still, 283-287 fsb is the highest I've gotten the same CPU on several other motherboards so I guess I can't complain.

I am going to try bumping the pots on my Sparkle 400W power supply. I also will try a 520W Fortran I have on order.

Still, this board is the most CPU stable board I've seen. The 2.7 VDIMM limit is not an issue since I have to run 3:2 anyway.

My beef about DFI is where can you get their boards? Nobody has the Rev. B yet and I notice the Infinity boards are not available in the US. There are no 875Pro boards in Japan.

[Citation4444]

Newegg has the 875ProB in stock. They do not have the Infinity 875 though.

[Clevor]

But that is probably the A rev, and Newegg won't guarantee revisions, nor will they check to tell you what it is.

Even in Japan, there were only maybe 15 Infinity boards in all of Akihabara. The AMD Lan Party board was sold in a few stores, but no Intel boards.

It seems to me my DFI board freely gives out the volts; it has the best VCORE regulation of any board I've tried. Maybe that's why my PSU might be crapping out when I have a power hungry video card in the AGP slot.

It's clearly stated as the B version in the model number there. (http://www.newegg.com/app/ViewProduct.asp?submit=manufactory&manufactory=1307&catalog=280&DEPA=1&sortby=14&order=1) . Since it's in the model number, I think you can be reasonably assured that's what you're going to get. If not, it can be returned immediately.

[Clevor]

Hmmm, that's interesting. Looks like it is a Rev. B.

I've been able to do 268-273, 1:1 or so with the 2.7 VDIMM limit on my ADATA PC450. I'm thinking 290 is not out of reach with perhaps 2.9 volts. Even 283, 1:1 would be awesome, perhaps 3800-3900 unbuffered.

I got a replacement IC7-MaxIII board from Newegg. If this one has the same problems as the first one, maybe I'll request an exchange for the DFI.

[RandomZero]

Heya, first post in this forum for me here....

I found this thread today about an hour after I ordered this board from Newegg. Obviously I had no clue that there was a revision b, even though my part number is listed as such from Newegg - MB DFI LANPARTY LP-PRO 875B RTL.

Even the couple of current reviews are still using the A revision, as they have all mentioned the vdim stopping at 2.7. This was a big concern for me, but now that I see the B revision hits 2.9 I'm less worried. Arriving with the board is a gig of Coirsair TwinX PC3700, but no CPU. I'll hopefully be able to confirm the B revision by checking part numbers on the MB itself, but until I am able to order the CPU for it, I won't be able to report on performance :( Should be about 2 more weeks before I can order that.

Anyway, glad I found this forum, and thanks for all the info in the thread. I actually read every damn post. :)

[Angry_Games]

visual differences in the two revisions are easy to make out:

A revision has only orange UV plastic
B revision has mostly orange but two of the RAM slots are UV green, and one PATA raid connector is UV green.

A revision board is still great, getting very nice clocks from it, but the B board can already do what the A cannot because of hte increased voltage. I could never hit 225FSB on the A revision with Buffalo PC3200 CH-5 Winbond.

On the B revision, I can easily do 225FSB @ stock DDR400 timings of 8-3-3-2.5. My vdimm isnt even cranked to 2.9 yet. With 2x256 of Buffalo PC4200 (Hynix) arriving in a couple days, it should easily do 290 or better. A few have gotten the DFI up to 270 with PC4000/4200 RAM.

Random: heh good choice on boards! I am a DFI employee here to help you with any situations or questions you might have =)

There are many vendors selling both revisions of these boards, and the Infinity boards. Please check www.dfi.com.tw and look for the reseller link. I've seen newegg stock the I875 Infinity, and my I875 Infinity came from stock that was being shipped to one of the USA vendors. Also the I865PE is a very strong clocker.

CMOS Reloaded is available on both the LanParty I875B and the Infinity I865PE boards. It will soon be available for all LanParty boards I think.

[RandomZero]

Thanks Angry,

Definately feeling much more confident that I made the right purchase. I'm switching back to Intell after about 2 years with AMD myself, so was a bit out of the loop.

As for the board revision, what you describe is exactly the pictures that Newegg is showing for the LP 875, so I'm guessing they are correct with the model number and that is what I will be receiving.

Thanks.

[Clevor]

Well I bumped the pots of my 400W Sparkle supply and got my rail up to spec, but I keep getting random reboots while running 3D until I drop down to 283 or so. This is disappointing since the board seems 2D stable at 292 fsb. I think there is an issue with the AGP slot.

Another problem I notice is with a USB250 Zip drive. I get a hang on boot when it is plugged in. I have to plug it in after I boot Windows. This is a common problem of Epox boards.

Yes, 5:4 does not work. Last night I tried my Corsair XMS3500 again (BH-5). I figured it must work at 3:2, 288 fsb where I am at DDR380. At 2.7 volts, I can run 2-2-2-5 Memtest clean. I got close to 3000 unbuffered! When I tried to take a Sandra screenie the system rebooted. Sigh. Still not stable. So BH-5 is unstable at all mem ratios.

I do notice I am getting about 50 higher unbuffered points over my Epox 4PCA3+ board at same 272, 1:1 setting. So the board has potential if some of these issues can be cleared up.

Hope you can get DFI to look into these issues.

[RandomZero]

Board came in today.

Wow, even though I knew what to expect with the bundle it was still a jaw dropper to see it in person. Anyway, it is the B revision, so once the CPU comes in I'll put this thing to the test.

[Clevor]

Maybe you will get an MO step. I tested an MO step in the Infinity board and it was totally stable at 292 fsb, and seemed to be much happier there than my L310xxx Malay. I was running 1.62 VCORE on the MO and did not try higher. Again, I need to see where it's actually 3D stable with these later, sissy video cards.

[Clevor]

I did more testing on the DFI 875P Infinity board, and I stand corrected on it. It runs ADATA PC4000 fine, at 1:1, 5:4 and 3:2. Previously I said it only likes ADATA PC450.

Also, with a 9800 Pro and a Radeon 8500 card, I was able to run 3D stable at 289 fsb.

I just tested an Asus P4P800-D last night, and it has the same issues with the video card crapping out in 3D at high fsb. I maxed out at 286 fsb with that board. I've also tried the CPU on a P4C800-E (287 fsb) and Abit IC7-MaxIII (288 fsb).

So far I have tried six 2.40Cs, including an MO step, and the best ones all maxed out at around 285-289 fsb, 3D stable. OCZ Technology also has found the CPUs max out around 285. Memtest is clean well above that, but 3DMark keeps kicking out or locking up until you drop the fsb. I believe it is a NB or Intel chipset issue.

Anybody who says he is running 3.5 gig or 292 fsb on air is BS, from my testing. Look hard enough and you will find the rig is not entirely 3D stable.

The DFI board is the best overclocking board of all the ones I've tried. Just remember I could not run BH-5 stable on it at any mem ratio.

[Angry_Games]

thx for keeping up here Clevor. I am having problems getting the I875B board up past 245 @ 1:1 with PC4300 BUffalo (Hynix 533). I havent tried a ratio, as I am trying to max it on 1:1 first. I've tried all combinations of voltages etc and it just wont post past 245...you maybe think of something I am missing?

[Clevor]

Angry, what CPU are you using? Your sig says 2.0??? Is that a 2.0A?

Yes, all the PC4000 I've tried should do at least 260, 1:1, so it's possible your CPU is holding you back, but I think only the 3.0 or 3.2Cs would have trouble getting past 245 fsb.

[Angry_Games]

lol forget to change my sig my rigs have changed so fast!

here's the I875B:

P4 2.4C 1.525v FPO/Batch: L320A617 packdate: 6/16/03 (mysteriously it doesnt say Costa Rica or Malaysia or anything else on the box heh)

I875B LanParty
2x256 PC4300 Buffalo Technologies DDR533 (Hynix)
WD 800JB Special Edition
MSI DragonWriter 52x24x52
ATI Radeon 9700P
SB Audigy
SLK-947U + Smartfan2
Chieftech ATX w/420watt ISO PSU

think thats about it. Im pretty sure its this RAM that is doing it...as it ran my Buffalo PC3200 @ 240 no problem, hell it ran that at 225 still running stock timings and voltages (8-3-3-2.5)!!!. So seeing that I am limited to 490DDR so far makes me kinda crazy lol.

lemme know if i forgot anything =)!

edit: heh i think i fixed my sig...ever rig changes so fast i cant keep up!

[Clevor]

Angry, are you fixing the PCI/AGP bus at 33/66? One reason I think of it is there is a rumor the PCI/AGP fix doesn't work on the 'B' board, even if you set it.

But, yes, even the worse 2.40C I got did up to 250-255. Some retail boxes don't have location of manufacture but the Lxxxxs were all made in Malay and should be good overclockers.

[Angry_Games]

ya im locking the bus, and as far as I can tell it locks good and tight as my Audigy would be the first to die if it wasnt a good lock. Never heard the B board not being able to lock the bus lol.

I do have a latest BIOS for this B board that is supposed to go official any day, or already might be official. Until I flash it to that, I can't comment any more but I am pretty sure like you, that my cpu is not the limiter here. I feel like maybe teh Hynix DDR533 and this BIOS might not like each other =/

maybe ill get un-busy enough to actually flash the damn BIOS nad play with it some more lol.

gonna drop a Raptor in there after I am done testing it on the NF2 =)

cant wait to get a bit more cash and grab a second raptor to raid those babies =)

[Clevor]

I feel like maybe teh Hynix DDR533 and this BIOS might not like each other =/

All the Hynix 4.0 ns (PC4000-PC4300) and 4.5 ns stuff I've tried perform well beyond specs: 268-279, 1:1, with two 512 MB sticks. Even on the Infinity board which is limited to 2.7 VDIMM I was able to do 268-275 3D stable, at 1:1, 2.5/3-4-4-7.

You should test the sticks out individually. Maybe you got a bad one.

[Angry_Games]

rgr that, as soon as DFI stops sending me boards i will get that tested hehe (got flooded last week and this week with boards =)

how about GEIL Platinum PC4000 or PC4200...any experience with that?

[Clevor]

No, I haven't tried the Geil PC4000 stuff, but I believe it uses the same Hynix 4.0 ns chips as the ADATA and OCZ.

I've had such good luck with Corsair XMS3500 (BH-5) on AMD and Intel boards, as well as ADATA PC4000, I have not tried Geil, Kingston HyperX, or OCZ ram. I did try a pair of 256 MB OCZ PC4000 EL Golds and they maxed out at 260, 1:1.

BTW, what is the difference between the 875 Infinity and 875P Infinity boards? I believe the latter is a deluxe version as it certainly comes with everything but the kitchen sink (firewire).

Is the 875P Infinity and the LanParty 875B boards 4 or 6 layer PCB? I think 4-layer like the Asus boards.

[Angry_Games]

ill ask the lab in taiwan but i think they are all 4layer boards now since they are in their second revision. again not sure but ill definitely ask.

875 and 875P...you hit it on the head...i've got hte I875P Infinity and its got pretty much everything the lanparty board does other htan the colors and accessories. I've never honestly seen the non-P infinity board lol.

I've tested HyperX PC3500, and its great as long as you dont want to go above it's rated speed of 217....on every DFI board in the house, it would never go above 217 1:1 no matter what, and hated ratios.

OCZ i've never owned a stick of it in my life. XMS wont go above 200FSB on the NF2 boards that we make (PC3200) but haven't had opportunity to test much on the I875 or I875B board.

if GEIL is using the same Hynix, it should rock like this PC4300 but better...im still not able to do over 245FSB 1:1 but i still have not tested a stick at a time either so thats moot for now. Im lookin into some GEIL Platinum pc4200 or some TwinMOS PC3700 "Twister" modules...

I just got a PM from a guy called notorious$(something or other lol) who is having an issue with overclocking the XMS but I dont know which speed he has. I told him to check this thread and to chekc AMDMB.com DFI section. If he posts here, i feel like you could give him some help on it since ive not tested the XMS yet.

also Clev, you have an account at AMDMB forums? if so, how about looking us up in the DFI section and posting in any ofthe P4 stuff you see (there's not really any right now but occasionally we get em =)

Thx!

Are you talking about on your AMD board? I actually got an NFII LanParty board a couple of months ago but have really procrastinated with getting my AMD rigs up. Now I understand the 'B' version is out with more voltage options. :(

As I mentioned, I have not been able to get BH-5 to work on the 875P Infinity board at any mem ratio. Mainly 3D kicks out immediately. It is a common problem with high performance boards such as the IC7-MaxIII. Next time I have the board installed I will try relaxing the memory settings in the BIOS, as I mainly run the highest HPS3 setting.

I will also test the XMS3500 on the NFII board, but I would really be surprised if it didn't run over 200 fsb at 2-2-2-5, which it has done on the 8RDA+ and NF7-S boards (up to 228 on unmodded boards!).

My main complaint about the NFII board is there are no mounting holes for Alpha heatsinks! This is a major omission. I had to buy an SKU900 sink just for this board, and my testing on P4 boards shows it does not outperform the Alpha (runs 4-5 C hotter), using the same Vantec Tornado fan. IMO this Thermalright heatsink is overrated. All testing in the reviews has been done with higher output fans compared to the old reviews with the Alpha.

I don't imagine the 'B' NFII board will have the mounting holes? :(

I do visit the AMDMB forums but I didn't know they had a P4 section! Will check it out.

[Angry_Games]

heh, no the PM I mentioned was here, about the P4 LanParty. I was mainly figuring you could help him cuz you have the LP P4 and XMS heh.

The NF2 B revision does have mount holes. Mine shows up Friday. Has a lot of other goodies too like 4x SATA w/RAID.

XMS doesn't like the NF2 board more than 200FSB heh. Been testing that lil ditty all week long =/.

strange about hte BH-5 on the Infinity...dun have no BH-5 to play with, but CH-5 rox on it very well! Low voltages on teh 875P make it tough to use pc3200 or 3500...

ugh gotta jet but ill swing the guy around this way a bit...as for AMDMB we have just a tiny lil Intel section, but for DFI, i ask that all DFI stuff, whether its AMD or Intel, be brought out in the open on the DFI section =)

T

[Clevor]

It seems the problem with the NFII board is primarily with Corsair XMS3200 LLs, which used to be BH-6 for a short time, but then was changed to some other chip. I don't think they ever used BH-5 in them. However BH-6 behaves similar to BH-5. I will see how the XMS3500 with BH-5 behaves in the board. It could be the PCB or layout of resistors on the board.

Even at 3:2, 2-2-2-5 I had problems with the BH-5 on the Infinity board, and 2.7 VDIMM is sufficient there. I believe ALL the ram manufacturers as well as Intel know there is a 5:4 issue with the SD/CW boards, but won't admit it. Face it, these guys have all day to play with ram on what, maybe 20 or so motherboards and they haven't experienced the problem? Epox and Asus have solved the problem, inadvertedly anyway. Don't know whether the solution is in the BIOs or hardware.

I've heard that slower, low performance ram runs OK at 5:4, but you are stuck at 2.4-3-3-6 or 2.5-4-4-7 settings, e.g. Infineon or Mosel chips. I would get DS 512 MB sticks to maximize the unbuffered bandwidth, though it doesn't improve it as much as with PC4000.

[Angry_Games]

sorry I been away so long, got all flu sick and such ;)

still not had the chance to test these PC4300 sticks one at a time (got the LanParty B board and the Infinity, only had time to install the LP board).

Let me know if anything new and exciting has happened =)

[vlad1966]

Has anyone tried this RAM:
http://www.newegg.com/app/ViewProductDesc.asp?description=20-144-517&catalog=147&depa=1
with the Lan Party 875B Pro?

[Angry_Games]

it should be top notch as the GEIL Platinum PC4200 rocks on this board =)

[Angry_Games]

thought i would throw a little bump before it goes off the first page!

[Methodx]

Can anyone help?

I keep reading about all these people just messing around and hitting 260, 280, or 292 fsb speed, but i can't go over about 245.

Basically, I can hit 992.9 mhz fsb, but not 1ghz? What's happening?

I thought maybe my northbridge was overheating so I put a fan on there. But it didn't help.

When I overclock I can hit 992.9 mhz front side bus, but if i do exactly 1 ghz or over the computer crashes. I have a nice cpu fan, heatsink on the southbridge, and big heatsink plus fan on the northbridge.

When I try to overclock anymore, Windows XP Pro boots up and runs for about 20 seconds, then video gets weird, then it crashes (reboots). It seems like its maybe an agp problem?

PLEASE HELP!

Why is the 1ghz barrier the problem? BTW, I already locked my agp/pci at 33/66/100. My specs are in my sig and I'm so frustrated! I just spent $180 on this motherboard instead of the cheaper p4p800 because i wanted to be sure I could oc to at least 260.

I PMed Angry_Games, but thought I would post here too in case anyone had any more info.

[Angry_Games]

method your RAM might be part of this equation, but hten again this sound VERY similar to the problem I am having with my Buffalo PC4300 HynixB...i cannot get it to post over 245 1:1 no matter what with this RAM, but with Buffalo PC3700 BH-5 and OCZ Gold BH-5 3700 I can get it to post at 266FSB 1:1 no problem, and even run Windows stable...I suggest trying some different RAM if you can just to test and see if you get anything different =/

[Methodx]

I thought of that, but see I am already running my ram 5:4. So basically I have DDR443 ram running at about DDR385.

The one thing I noticed however was that my motherboard set the timings of my ram to be 5 3 3 2. If I loosened these do you think that could help?

Also, for that system bandwidth setting, should it be lps1, 2, or 3? I really dont understand that setting.

Thank you for your help!

[Methodx]

OK, I solved the problem, but gained a new one.

The ram was auto timed by the motherboard to be 5,3,3,2 which was way too tight. When I losened them timing up I got up to fsb 274.

However, the motherboard seems to have problems with the ram now. When I boot, the loading screen says the ram is running at 20 mhz. This happened down do around fsb 266 and then it registers correctly and says like ddr425 (i'm operating in a 5:4 divider). My ram is rated to ddr433, so it should be having any problems. CPUZ recognizes 512mb ram, but can't tell what kind or what speed and says there is a "driver error" when I load it up.

Why is the motherboard unable to detect the ram properly at startup when I am running the ram slower than its stock speed?

Anyone have any info? Thanks in advance!

[Angry_Games]

aye forgot about the LPS/HPS settings in the BIOS. In the advanced chipset section, you can completely turn off this feature, to gain full control of your RAM. Your timings will still be limited to a maximum of 10-4-4-3, but you should be able to get even higher with teh system bandwidth disabled and set to manual.

Otherwise, make sure it is is LPS1 for overclocking (i recommend disabling it!).

as for the boot screen only showing 20Mhz, make sure you have the latest official BIOS for this board, and again, the system bandwidth disabled so you can set it manually.

let me know if this helps at all =) (the 875B is my main rig so I have to turn it off to get to BIOS and see these things for the moment =)

[Methodx]

OK, everything loooks great so far, and I'm now prime95 stable at 3.4 ghz! Awesome. I went higher before but I decided to tone it down a little.

The only issue is that the memory frequency still shows up low when I boot. The reading says the memory is at 8 mhz.

Im running a fsb of 262 and with a 5:4 divider that means my ram is actually running at 209.6. Now, Windows and CPUZ both recognize my ram properly now. Like I said, the mobo reports 8 mhz. If I slow my memory down 8 mhz, it reports the memory correctly (401 mhz). If I speed up even 1 mhz past that, the motherboard reports memory speed of 1 mhz. It keeps going up like this as high as I take my ram (I've gotten it up to 28 mhz for example).

In the bios, my badnwidth is set at lps1. I've heard a few times that you can disable this, but I haven't been able to see where. I'd like to turn it off! I looked in the advanced chipset menu in the bios but didn't see anything, can you tell me what the setting is called? I'm probably looking right over it.

Anyway, thanks again for your help and helping me reach my ocing goals! This was my first oc, sorry I had so many questions. ;)

[Angry_Games]

method gimme a few minutes, ill reboot and take some pics =)

[Methodx]

Hmm, lack of screenies :p

[Angry_Games]

/hammer to face

ack forgot to take the damn pics lol.

rebooting right now to take em =)

gimme about 30 minutes to get em up in a page ;)

[Angry_Games]

http://www.angrygames.com/pics/I875BLP_bios1.jpg

the highlighted red one is the setting you are looking for =)

[Methodx]

I saw lps1, 2, 3, hps, etc. I just didn't see the "disabled" setting LOL.

Thanks for the help!

[Methodx]

Angry games, I look in my bios settings, and I do not see a "disabled" setting. I just see lps1, lps2, etc. You have to pick between this choices but I don't see where I can disable it.
