Why cant I O/C? P3V4X This is a O/C Fourm right??? can someone help?

[AlphaEETA]

I have:
Asus P3V4X (w/ new BIOS)
P3-850Mhz
256mb PC-133 CL=2 Crucial ram
20GB IBM hd
etc.
AND IT WONT LET ME OVERCLOCK PAST 894Mhz! WHAT THE &$#* is WRONG!!!!!!!? what are the BIOS settings that will alow me to O/C to 1Ghz(or past 894Mhz)....ive seen that alot so i know it can do it....PLEASE HELP!!!!!:mad:

Hi AlphaEETA, wellcome to the Forum,
Well, to OC your chip you must set the Fsb from the original 100Mhz to 133Mhz, but your chip temps never must go over 50 Degree C @full load (100% load) but less is better, and if not stable rise a little the chip Voltage (VCore), not over the 15% of the standard value.
To check your system temps I suggest you MotherBoardMonitor, that you found at http://mbm.livewiredev.com/

I hope it helps you ;)

If you need more voltage on this motherboard, you have to set it in the bios, restart into the os, then go back into the bios and change your fsb. For some reason the voltage stays at default until it boots into the os.

[AlphaEETA]

i know how to do all of that.....but when i set the FSB greater than 105Mhz it does't POST.....that is what my problem is...i need to know the settings so it will POST and allow me to O/C to 133Mhz FSB hense the 1.033Ghz P3

[Sohryu Asuka Langley]

If that chip was meant to run at 1Ghz..then it would come in a box that said that and sold for more. All chips are different. You may just have an unlucky one [cB0] :(

[funnyperson1]

i would suggest that you get better cooling like maybe dishig out 20 bucks for a new heatsink for example with the stock hs i was able to get 780mhz tops, and with the new one i can hit 840 stably....your mobo should do you well...it aint bad at all...if you want to oc and your chip cant do it, go get a p3700 or a p3800....

[AlphaEETA]

I have 8 fans in my case.....heat is not really and Issue....:D
so what ur saying is i cant O/C?

[CrystalMethod]

Not saying that you can't OC it. But to help you, I need to know a few more things. Do you have a SLOT1 CPU, or an FC-PGA on a converter card? What heatsink and fan combo are you using? having 8 fans is great and all, but it won't necessisarily help keep the CPU cool, if you've got a crappy heatsink and fan. I personally have a P3V4X with a celeron 800, and I've hit over 1Ghz with it. It might be just the chip that won't do it, but I doubt it.

[AlphaEETA]

i have an Antech Heatsink w/ 2 fans build in........then i have a 92mm Fan blowing across that.....the blowing on the side of it i have a 72mm fan......then i have a Antech exhust fan about 2inch below the processor....its a Slot1
and it runs about 40-43 cel. and never goes above 48 or so

[AmbientFiction]

That could be your problem right there its a slot. Might also trying to find the clock gen and then Boot into OS and raise the FSB with a program like SoftFSB in windows. Also what is your PCI at it could be you have a card crapping out at 105mhz

[AlphaEETA]

i have a Voodoo 3 3000 PCI
Diamond MX300 soundcard
SOHOware Network card
PCI Bus Speed: 35Mhz
Speed Mutilpyer: 1/3x
ill try SoftFSB.....but do i have to worry about frying my PCI ****??
i dont think i do....but not sure....

[funnyperson1]

if you go around buying generic stuff, sure itll fry, but most good components wont....

[grovermonster67]

I noticed you have exactly the same problem I have trying to get my PIII 850 on an ASUS P3V4X to o/c beyond 980...I can't get my FSB above 115. The ASUS website offered the advice of BIOS 1006 to run a PIII 1000 @ 133 so I found a 1006.003 beta and flashed it....nothing. Still won't boot beyond 115...what to do? I know the literature says PIII up to "733+" but there should be a way to get over 15% boost. Running the vcore @ 1.85 or even 1.9 doesn't help. Did get it to POST up through to Diskminder {due to no previous boot =) } running at 1.05 GHz @ 124 but then crapped out at that point.
Just how are some of you guys getting 25%+ increases? I'm green with envy (and apparently on skills)

PIII 850/ running at 980 (Slot 1)
768 MB PC133 Crucial CL 2 RAM
Maxtor 27 GB HDD @ 7200
Quantum 8.4 @ 5400
Matrox G450 DH
SoundBlaster Live! Value
Linksys 10/100 NIC
Philips 404 CD-RW
Toshiba 12X DVD
350W PS
Dual-fan HDD 5 1/2" bay fan
Chassis fan
6" PCI case fan (o/c was attempted before installing as well as after...could this be a weak link?)

[AlphaEETA]

how did u get it to 980???:eek:

[AmbientFiction]

Huh I see your useing a slocket well that could be a major problem how nice of a slocket do you have if you have a cheap slocket it will screw you over when you try and push it.

[grovermonster67]

850 @ 115..the bios says 980 even if the math says 977.5, Sandra generally had it at 852 or 3 before any o/cing..
So I take it sockets are better than slots? Both the CPU and mobo are less than 6 months old. Guess I didn't luck out and get one of its speedier brothers from the same mold.

[AlphaEETA]

i have the ASUS P3V4X mobo......i just want to O/C past 105mhz FSB...
my mother board ist an Option in SoftFSB.....what do i do?

[Silversinksam]

I suggest you you read this article (http://www.overclockers.com/tips116/) regarding the P3V4X and cooling the clock generator, That tiny chip does get mighty hot and what I used was a radioshack Cat.#: 276-1368 Its a perfect fit and was affixed with a small amount of Arctic SilverAdhesive, but RadioShack also sells thermal adhesive that will work also.

These heatsinks also work excellent for Ramsinks.

It looks like out of 67 entries using the OC.com Cpu database that the average OC is 1021 Mhz , so maybe there is hope.

[It_The_Cow]

From what I can determine, you probably have a newer version of the P3V4X. That means that cooling the clock generator won't be necessary. It still isn't necessary if you plan to run it at 133 anyways. The cooling usually only helps when running above and beyond 133.

As for flashing the BIOS, it won't mean it will allow you to instantly run at 133. It only provides better support for it if you have an out-dated BIOS. I know since the 1006 Beta didn't allow me to overclock anymore than the 1005.

The problem probably lies within your processor. The high multiplier restricts your capabilities, the stepping should be able to get you some stability in the 900s. You probably just got a bad overclocking chip.

You should also try CPU FSB. I know for sure it supports the P3V4X, and many others SoftFSB doesn't

[[Oc]acaridans]

Have you tryed removing any of your cards while trying the O/C??
I would try without the NIC and sound card...

In the BIOS for the Speed Mutilpyer there is a AUTO feature (atleast on mine there is) try setting that.

Have you played with your CAS settings?? try raising them.

And 1 other thing that sounds wierd, put your memory stick into 1 of the 2 middle memory slots...This worked for me when jumping from 140 to 150FSB.

[AlphaEETA]

in the Program CPUFSB what is PLL manu fact. what do i set that too??

[TUK101]

Hey dude, what size power supply do you have? With that many fans and all of the stuf you are running....you could be running short on juice too. That many fans in one case is not really helping you any, after awhile they are just fighting one another for air to blow around and sucking up juice. Also, have you tried to just set to 133 fsb and see if it will boot on that setting? I have had chips that wont boot on the oddball settings. but will on the mainstream settings (66 100 133fsb settings). Just a few suggestions.

Next to your DIMM's on the right you will see 2 chips, 1 will be a silver oval abd the other a black rectangle....read the black 1 that is your clock gen. it will either be from ICS or Windond....for example, my p3v4x is a Winbond the first line of the chip reads, WB3195R-08, this is what you select in CPUFSB.

[AlphaEETA]

When I O/C using CPUFSB i got a Kernal32.dll error......could this mean somthing?? it happend when i set the FSB too 110Mhz

[funnyperson1]

oh, that means that it wont work at that speed.....its the equivalent of not booting up....

[AlphaEETA]

i guess i can O/C past 105Mhz...GAY!!
thnx for all youre help guys

[Burning Phoenix]

I have used quite a few slot 1 chips this year and have always used the ASUS P3V4X boards. The best chips i have had success with on these boards being only slot 1's were the P3 700 and P3 800. Had the 700@1022 and 800 @1120 with water/peltier setup though. I never had luck with the 850 by the way. I could only get into the 900's. Also stock heatsink and fans never got me far either.

At all of those settings the PCI and AGP buses are running at their designed spec. Anything else is overclocking the cards ect. Also the suggestion about the power supply is right on. It's not just air blowing around that cools you but how that air is moving. You can actually trap heated air around your cpu by making it swirl. Also how congested is the inside of your case. Try to arrange your wiring so that it allows the air to flow as unrestricted as possible. And finally be sure that one fan is blowing "in" at the front bottom of the case and one is blowing out the rear as close to the top of the case as possible.

[AlphaEETA]

the HEAT is not a problem......my MOBO temp is 32......i have a 320watt Power supply

[JetMech]

Have you tried the jump straight to 133mhz?

Yeah, I thought that too when I first arrived here. I thought "I know my S**T, WTF are these guys going on about heat? I'm reading 27ºC cpu, and 34ºC ambient!!!". Turns out, I was dead wrong. Batboy, Kingslayer, Mr.B, Hoot, and too many others to name showed me the error of my ways. Never rely on what software temp monitoring program you have, they're too inaccurate. Listen to the guys that have been here and know what they're talking about. I'm not talking about the guys who have the most posts, I'm talking about the Seniors, and Moderators, the rest of us you have to take advice from with a grain of salt. (Sorry to all those that I may offend here, but let's keep a guy from frying a cpu, that could be put to good use...). I'm not saying that the Seniors and Moderator's know everything(My God am I treading on thin ice here...). But, your own good judgement should save you , and allow you a safe and productive OC, without the burden of posting "I killed my CPU..." But, like with anything, take my advive with a grain of salt, as I'm kinda tipsy, and I blame my friend DAVE!!! who shows no sign of remorse, and just wants to get this engine we're suposed to be re-building done...
I think it was the prospect of beer that lured him in...

[M00CH]

I too have ahd problems with this board....

i've seen PIII 700 oc to 1024.
i have a 733 fsb133 and it wont oc to anything past 875 fsb 150give or take....

cooling is not an issue neither is other componets, or ram it just wont oc anyhigher........

[AlphaEETA]

im tired of ****ing with my CPU....so i guess im not goin to O/C........later on ill get a Flichip covetor card and get a cheap ass cellry and let it go......till then...if anyone figues out this biatch(ive been looking for about 2 months)let me know
