Intel D 805 OC Project

[wing]

Hi all,

Been a while since I have been here but this project comming up I knew the place to go from my past experience!

As many of you I am sure I read the THG article on the 4.1ghz OC of the D 805 B0. So of course I jumped on it. Currently I have a P4 650 3.4 OC'd to 4.05 (4.2 in the winter...house to warm in the summer to sustain it hehe) without issue on air with a zalman copper heatsink (I cant remember the model but its that huge one that looks like a flower)

Anyway I picked up an 805 at newegg and also decided to get and try the same HSF that they used in the THG article (ZALMAN CNPS9500 LED 92mm 2 Ball Blue LED Light Cooling Fan with Heatsink) to see if it works any better than the one I currently have.

The chip should be arriving today and I am dissapointed that I wont have time this evening to start messing with it but that gives me the chance to ask a couple questions first.

What is the temperature range at which the CPU begins to throtle back (i.e. what should I keep it under).

The mobo it will be on is my Abit AW8-Max.

Thanks..more to come I am sure :)

[batboy]

You will want at least BIOS version 14 in order to fully support a Pentium D. I think thermal throttling begins somewhere above 70 degrees, but the Abit AW8 series tends to report lower than actual temps.

[Mr.Guvernment]

for most CPU's i would say keep it below 50C if you can, 55C is probably safe, but after that i just dont like my temps that high.


good luck on it, nice to get such a cheap chip and make it perform better then a $300 chip :D

[wing]

Hi batboy, good to see you again, I remember you helped me a lot when i was deciding what to do with my rig last time.

Guvernment - my current rig i keep the max load temps under 60C, when under full load thats what it gets up to just about. When it started to turn summery around here and I still had it OC'd to 4.2 It would start to restart when ambients got too high in the room. I notice the 650 causes a reboot at about 65-66C
-
What was the name of the program again to see whether the CPU is being throttled or not.
-
Here is a secondary question also...

What I want to do is to do some benchmarks to see if my 650 OC'd to 4.2 (I can crank up the AC to simulate winter temperatures, hehe) is faster or slower than the 805 OC'd to whatever I can get it to. But obviously the 650 is single core and 805 is dual core. What benchmarking program can I use to give me comparable results to tell whether either one is faster. I know some benchmark apps only utilize a single core, which would do no good because it wouldnt give me "real" results with the 805.

What would anyone suggest to get reliable numbers in this experiment.

Thanks :)

[batboy]

Hey right back at ya. Glad to help. Probably can't keep an overclocked 805 below 50 C unless you are watercooled. Those dual core Smithfield do run warm. Try not to exceed 60 degrees.

If you want to just use only one benchmark program, then go with PCmark2004. I typically use Super Pi too. If you want to compare video/gaming capabilities, then also try 3Dmark05.

[Jame Gumb]

Relying purely on software for temps kinds sucks because you never know for sure with it, but sometimes it's all you have. I used thermal watch and I never got my 805 to throttle and I've been at 68ºC (according to Ai*Booster) ...<<< I had my xp90 on it and I forgot to turn up the fan in Oblivion.

My idle temps are 45ºC idle with an si120 and three 120mm Panaflo's@7v. My game load temps are 60 to 65 at 4ghz....but I run it lower than that now at 3.8 and it gets into the 50's in game loads, fans @12v.

[dwschoon]

I am running a 506 @ 4.3ghz @1.5v on an AS8. I am folding right now and cpu temp is 45 degrees according to abit eq. System temp is 26 degrees, and at idle the cpu is under 30. I am running a thermaltake big typhoon. I am in the basement at my office, so ambient temps dont fluctuate. I think it stays around 70-72 degrees down here.

[wing]

Cool Jame- I am probably going to try to suck a lot out of you since it looks like youve already done what I'm doing :)

What did you have before the 805? Think it would be faster than my current setup? (See sig)

Thx

[Jame Gumb]

About the same thing....ASRock 939 dual sata(all mods) 3200 Venice OC to the max. Only thing changed was the RAM and of course I play COD/COD2 and oblivion takes advantage of two cores.

I changed from bluestorm to a Tagan 580 w/ combinable rails >dual>to>single 35amps............which you will need for these puppies. I sent back my Zeus and took this Tagan.

Is there a thread on combining 2 rails into 1? I just bought a Powerstream 600W dual rail by mistake, but if I can combine the rails, it will save me from having to RMA it.

[wing]

Just got my CPU and i was looking on the box and notice that it says 533FSB, so does the screenshot of the box on THG, when they key feature of this thing is the 133fsb. How come the box says that?

Intel markets their cpus as "quad pumped" fsb. so a 533fsb cpu will be running at 133 and an 800fsb cpu will be running at 200. The memory will also be running at the fsb unless it is on a divider.

I don't think it's exclusive to Tagan/Topower but I don't know of any others that have the combinable 12v+ rails. Here is the PDF (http://www.tagan.com/pages/products/2forceS/TG-580-U22_Tagan_UK_mini.pdf), on the back it has a switch that lets me toggle from dual rail to single.

[Evilsizer]

well if he had electronic skills and could find the current limiter in the psu then it would be a single rail.

[BlackSphinx]

It throttles at about 70C.

3.8 is the max I can run it at, raising the voltage creates too much heat for most HSF to hold. The Zalman is superior to mine, but also 35$ more.

I run 3.6 at 41C idle 54C load. 3.8 is 44 idle, 63 load. So, yeah, 3.8 is possible, but for the performance boost I get, 3.6 is enough.

[bignick]

I have the same exact setup you have. I'm not really sure where it throttles at but it is around 65C. And you will see that it is a huge improvement over your current 650. I had a 630@3900mhz and my 805 at 3800mhz (1.5V) dominates it. The difference in 05' was 1100 points and 1700 points in 06'. Games run much smoother at higher resolutions now because my 7900GT is not bottlenecked any more. 192Mhz is the max I can go on the Zalman 9500. Anything above that requires to much voltage and the Zalman can't take it.

I've got mine at 3.8 right now too on the Blue Orb II cooler. As you said, it dominates any single core P4 at the same speed. I've got both a 506 and 524 at 4GHz and neither of them can hold a candle to the performance of the 805.

[SiliconSlick]

don't worry about relatively high temps. these things are built to handle the sixties (my 830 ran @ 61 stock and runs 66 @ 3.902 :))

[Jmag034]

i wouldnt get too worried about the temps of the CPU until 70c, but i would like to know what happens to the gases in the hsf when you reach 70ish celcius

[wing]

Cool bignick, thats what I wanted to hear :) I will be putting it in today and running some tests to see how it comes out. I have had really good luck with overclocking the 650 i have in there now so i am hoping for good things. I dont know if you have seen my other post or not but I just have to decide which HSF to put on it, the one currently in my signature system or the zal 9500 (i have both). Will be back with more questions/info I am sure later :)

Oh yeah and thanks for the comments on the temp, i know the ranges are different with every chip...my 650 dies at about 65C, so its good to know that the 805 can take a little more, i usually have to keep my 650 at 60C max to avoid throtling and crashage :)

Thanks

You might consider the thermaltake Big Typhoon.

That's Interesting to me because i have a 506 at 4.3ghz. I am looking at building an 805 setup, but I wonder how much o/c I have to get out of it to get better performance than my 506.

Larva has a 506 @4GHz (http://www.ocforums.com/showthread.php?t=422137). I compared his scores to mine and the results are pretty much the same. I have the same videocard as well. The only difference I see with my CPU is in games that take advantage of dual core. Like my COD/COD2 & Oblivion.

[Tserrof]

Yeah, in single threaded apps the performance is largely the same. But I was referring to the dual core advantage when I mentioned that neither the 524 or 506 could keep up with the 805 overall.

[wing]

Ok i got it in and running but am having a small issue.

I can get the FSB up to 169, but any higher and it wont boot period. I am running 169 right now at stock voltage and I tried 180 (which THG said they ran with no increase in voltage from stock) and it would not boot. I tried bumping the voltage to a high number just to try (1.45 and 1.5) which should have been plenty for that speed and still nothing.

I have an Antec Smartpower 450 W PSU

it has 2 12v rails (12v1 = 15A 12v2=17A) which I am not sure if that is why its having a problem booting...however its the only thing that makes any sense. But i did not have to bump the voltage at all to run this and shouldnt have to to run 180 but who knows.

Looking for advice. Thanks!

[Jame Gumb]

Sounds like one of those rails is pussn' out in the face of that 805.

What's the RAM again?

[start]

What speed is your RAM?

Don't be insulted if this seems like asking "Did you check the power was plugged in?". I'm just wondering.

[wing]

This is the memory that is installed.

CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM Unbuffered DDR2 800 (PC2 6400) Dual Channel Kit System Memory

Here are some CPUZ screenshots that may help.

http://www.ehrensplace.com/images/pentD169.gif

http://www.ehrensplace.com/images/pentd169mem.gif

With my other CPU I had the memory running at DDR2 790something speeds so I dont think its the memory. Think its the power supply? Thats my first thought but I havent even bumped up the stock voltage yet, however even though its at stock voltage I would think it draws more watts when the FSB is bumped up without increasing the voltage....not sure though.

What ya think? Thanks! :)

[Jame Gumb]

Did you try a stick at a time to see if you can go over?

[bignick]

I think it may need somemore volts. Not all chips are created equal. I would start at 1.425V and try it there. You will need 1.5V to hit 3800MHZ. IMO 1.5V is the highest safe voltage on air. As far as coolers go I'm not really impressed with the 9500 most of the guys that get 4000MHZ are using a ninja. As for me I'm selling this 805 I want another 930 (never should have sold it) until I build a Conroe system late this year. It just runs to hot and draws to much power.

[Jame Gumb]

I don't need 1.5v to hit 3800MHZ .....motherboard and chip difference. I think he said he tried 1.5.

[bignick]

Very true but we have the same mobo and the Vcore droop should be similar that's why I said that. I can't find any Vmods for the P5LD2 board I wish someone knew. I was also confused because in one post he said he tried 1.45/1.5V and no post but in another he said he didn't bump it. But after rereading I think the second post was referring to the ram. I think that PSU might be giving him trouble. I built a computer for a customer with a smartpower 500W and the rails were very weak I can't see the 450W being any better. I have a dual rail PSU also with 12V1@20A and the 12V2@19A and the rails are rock solid no matter what I throw at it so it not the dual rail design hurting him.

[wing]

more volts wasnt the answer, i bumped it up to 1.5vcore and still could not get the fsb over 169 and have it post. It comes on but displays nothing.

My rails are a bit weaker though... dont really know of any way to actually test what is being put out and what is being drawn, I am certainly not electrically inclined. I know the ram can take it because as I said it was up higher than it is now before and even now its not at DDR2 800 which is what it is rated for. As a side note i have the v of the ram bumped slightly to 1.8v, ive had better results with it that way.

So looks like its pretty much down to the PSU then eh? Any reccomendations on a replacement?

[Evilsizer]

could be wrong mem divider being used when tring to go higher. Could also be wrong northbridge strap. since you tring to find he highest the cpu can go. Its normally done by using the 1:1. Also your ram is rated for ddr-800 but the voltage you are using is 1.8v? If that is the case at rated speed and timing the voltage is prolly around 2v-2.1v. I would up the voltage to the ram at least to 2v. use the 1:1 mem ratio and try agian.

[wing]

On the mobo I have have the memory speed set to "By SPD" so as I bump up the fsb it is doing the memory automatically.

I do remember, and maybe this is noteworthy...that when i had it set up with my old rig I had the memory set the same way and it wasnt running at 800, so i set it to 800 and it would not boot. I am at work right now but I will have to try that later when i get home.

[wing]

Ok...So i got home and bumped up the voltage to the memory to 2v, still would not boot.

(when i say wont boot, i mean the power is on but it doesnt do anything else...i.e. fans run, but no screen)

Here are CPUZ shots for the CPU and Memory as it sits

http://www.ehrensplace.com/images/ocf/169cpuz.jpg http://www.ehrensplace.com/images/ocf/169cpuz_mem.jpg

Here are my bios settings for the CPU

http://www.ehrensplace.com/images/ocf/169bios.jpg

I am assuming by 1:1 you mean set the nbstrap to PSB800? Maybe you can tell a little better what I am working with by that screenshot and give me a little insight as to what to try.

I did bump the timings on my ram a little after increasing the voltage so thats good, didnt changed much, just changed the 12 to 10.

Think it could still be something with memory or the PSU?

Thanks again for all the insight!

[wing]

Here are a few more questions/misunderstandings.

First off here are the available options for the dram
http://www.ehrensplace.com/images/ocf/dramdiv.jpg


Here are the options for the nbstrap (what is nbstrap anyway?)
http://www.ehrensplace.com/images/ocf/nbstrap.jpg

If i set both options to by cpu and by spd it sets as this-
http://www.ehrensplace.com/images/ocf/bycpubyspd.jpg

however when it reboots (which it does fine) it sets itself to this-
http://www.ehrensplace.com/images/ocf/autoset.jpg


can you give me some insight as to what these settings actually are and what I should set them to, to try and get this to work if it were the memory and not the PSU.

Thanks!!

[Evilsizer]

there is your problem your still using the fsb533 strap. Im not complety sure how they work. From what i know its changing the speed seen by the NB and parts(ie. ram). As right now the wrong strap is causing some problems.

here is what i want you to do.
n/b strap is set to 800
set dram spec to 667 at first. (clock from here at first to find the highest the cpu will go)

find the option in the menu for setting ram timings. set the timings to what is labled for your sticks. i have reread every post but do not see what model and timings the ram is you are using.


after doing those 2 save settings reset.

now go back in and set
cpu-v to 1.45
ddr voltage @2.1v
mch & pci-e voltage to 1.55v

[wing]

Ok I tried all that with the same result.

I posted a link in a previous post up there with a direct link to newegg with my memory but the timings are 5-5-5-12, which I have them manually set to now. I set the strap to 800 and the memory to 633 and restarted fine.

Then i bumped up the voltages as you said and set the fsb to 174 just to test, saved and restarted and it was dead. (yes i know the cpu voltage is at stock in the screenshot but there was no reason to leave it bumped up if it wasnt working)

As a side note...any idea why the voltage area is greyed out in CPUZ?

What say ye now? Any more ideas. Kinda getting frustrated because it seems like it should be a no brainer. I dont know if the memory jsut sucks but i have a bit of a hard time believing that because it performed great when my other chip was OC'd by almost 1Ghz. The only thing that is really out of spec from the toms hardware review is my PSU but I dont know if thats it either. Alot of this doesnt really make any sense.

Here are screenshots

[Evilsizer]

could just be a poor clocking chip then. its always the luck of the draw.

[wing]

so nothing else to try? Could not possibly be the PSU?

When you raise the FSB even without raising the voltage does it draw significantly more watts or a barely noticeable amount?

Just ordered a Powerstream 520-ADJ-SLI because of its single 12v rail...did overnight shipping but with the holiday probably wont get till wednesday...d;oh

cant think of anything else at the moment unless anyone else can.

Thanks

[Jame Gumb]

Just a quick suggestion, even though that RAM should be able to do more. Have you tried one stick at a time in different slots, with different sticks? CPU-z sometimes it does that, just restart it, or is that version doing it everytime? Also what are the temps and what are you using to measure them? It just might be the CPU, or it could be the PSU, though I oced mine to 4GHz on a dual rail blue storm.

[wing]

No I havent tried that. I should just take one out and try it in single channel and try the OC? CPUZ is not reporting a voltage every time.

In a hot room (AC is off right now) idle temp is about 36C and load is 45-47C and I am using the mobo to get the temps. Maybe not 100% accurate but id say its a safe bet those temps are OK :)

How many watt was the PSU you used to OC yours? I have a raptor, a 250G drive, a X850, and all the other standard stuff in the system on a 450W antec. So I dunno. Kinda frustrating.

Is my NB strap and dram stuff set appropriately...I thought i knew what that was from before but I cant really remember.

Thanks :)

Yes, OC the CPU to the max and see if one of those sticks is messing up somehow. W/ my bluestorm / 460-480Watts max out put w/ 15 amps on one of the 12V+ rails, my Tagan crushes that. How many amps does that PSU you bought put out on the 12V+ ? Try an older version of CPU-z

[wing]

Well just tried the memory thing as you suggested to no avail. I tried each stick individually in each slot with the same results each time. This is almost mind boggling. why exactly at 169 fsb. If i set it to 170 fsb it boots but when i go into bios i see that it has reset itself to 169, anything over 170 and it just doesnt do anything.

the PSU I ordered does 34 amps on the 12v rail the one I have now does 13 and 15.

Older version of CPUZ doesnt show any voltage either, 1.24 just shows it as a P4HT (prescott)

Asuming everything is set proper on my MB its got to be down to either the Chip or the PSU now, which you do think is the better bet?

Thanks for the continued insight

[wing]

PS-

I just unplugged everything in my case that is not absoultely neccesary for the sytem to post (cdroms, hard drives, fans etc) and then tried the OC and it still did the same thing.

[BlackSphinx]

If you are still on the 2 rails PSU, it's normal, as one is used for the CPU only.

[wing]

What is normal?

I was just reading in my motherboard manual and contrary to what someone said, the motherboard manual said for 133mhz FSB cpu's that the NBStrap should be set to 533. I know ive tried that and that didnt work either though.

[Nandro]

I have the d805, actually the exact same one as on the THG article. Same numbers in all respects except I think the week it was made. I have it running in a P5ND2 MB and it runs all day long at 3.5ghz, I can get 4ghz, but craps out after a few min due to the PSU. I am sure its that. I have 2 very good psu's, but traded away my amd system to get the parts for intel, and it had a different power connector on the MB so I had to use my generic POS one to get me by till I can affor a good one. With my 7800GTX I am sure drawing a bit of power you should deffinitly be getting higher. I can do 3.66 for long periods, but a few rounds of 3dmark will kill it. I use the big typhoon, and it idles at 34C and maxes at 44-46C, so thats an excellent cooler although it is huge and not good if you need to move it around at all. Anyone want to trade my antec 460TB and Coolmax 550B for a good Intel PSU with the small plug :) Thats all I need, and people said NV chipsets sucked for OC'ing!

[Jame Gumb]

Forgot I had some car grit paper from an old waterblock project a few years ago. I wet lapped my 805 today with 400>600>1000>1500>2000 grit, mofo's polished up and almost 8-9 degree difference. I polished up an si-120 that was way off, and the 805 wasn't excactly what I'd call true. :) Have a big ty(for brother) comming with a ninja as well. AS5 still has to kick inf for another degree, maybe.

[wing]

OK, so heres the end of the story, just happened to be randomly browsing the Abit motherboard section and found a thread about someone else who couldnt get theirs over 170 fsb...same problem as me, found that intriguing. Read it and found that apparently there is a limitiation on the board for pentium 533 fsb cpu's.

Found this out AFTER purchasing another 805 to try it asuming it was a not so good chip. Damnit! Looks like I have 2x805's for sale now....

[Jame Gumb]

That sux, wing. Well I can confirm that the big typhoon destroys the scythe ninja on the 805. These were my findings.

[dwschoon]

That sux, wing. Well I can confirm that the big typhoon destroys the scythe ninja on the 805. These were my findings.

That's good to know. I really need to know how the Big Typhoon compares to the Ultra 120 on an 805.

[wing]

So this is me...I get into a project and can not accept defeat.

Therefore I just ordered a AW8D with overnight shipping that will be here tomorrow. I will get this mojammer to work and it will like it. It has the 975 chipset, whereas my aw8-max has the 955 so I will probably have to reinstall however I am going to try and avoid it. I will miss the 3rd eye of my aw8-max. I liked seeing the temps without having to have software open.

[SaDiStiC88]

If the Big ty can go up against the ultra-120. Does the Zalman 9500 match the Big ty when using the 805?

[Jame Gumb]

Tuniq tower 120 should be the king of air on the 805, and the big typhoon and 805 were meant for each other. What I saw was, the Ninja spiked in heat within a few seconds under prime, where the Big ty-ty fought the temps off for over 10 min with a very slow climb in temp.


My case has awesome air flow and it's empty. I was using three fans. One in take, out take and the CPU....all of them 120mm 115.7 CFM @ 2750 RPM, 45.5 dBA -- on full volts. The config on the ninja was a fan over the side by the ram, pointed toward the out take fan.

[Nandro]

I have the tower on mine, and at 3.8ghz under load both cores, it rarely gets over 48c with 50 being the highest I have seen when my room was hot. Also I see the D805 for $105

Getting quite cheap.
