Is 1.95volts on a 566@850 cc0 too high??

[badxxcow]

i have a celeron 566@850 1.95volts on a be6. it crashes at 1.9 so i bumped the voltage on my abit slocket to 1.9 and set the bios to 1.95. i ran the cpu warming test on the CPU Stability Test, and temperatures maxed at 35celcius. I have a golden orb running with thermal paste (not arctic silver), and two case fans. One blowing air out from the cpu, the other blowing air out of the side (near ram). I ran 3dMark2000 and passed (although with my voodoo3 2000pci got bad scores).
any comments? is 1.95 too high? im hoping to burn it in and bring it down to perhaps 1.85 or 1.9. thanx!

As long as t runs cool anything under 2v is ok, what I would do is to bring the speed down to 566 and set the voltage to 2v whilest you burn it in, I recomend setit prime95 and sandra burn in wizard, doing this on my 600 allowed me to run it at 900 with the default 1.7v and run it at 1008 with 1.9v

I agree with the above. Wouldn't go any higher than that. I have yet to try that burn-in at default speed trick, but it sounds feasable.

Can't force myself to pull the trigger on it though....got the bugger running pisser now...(cC0 600 Celeron @ 1045MHz) Can't bear to see 600 MHz in the BIOS.

I'm getting an Alpha PEP66 tomorrow, got the Arctic silver handy. Maybe after I set that up I'll give it a rip.

The next stop is 118FSB (1062 MHz)....gotta admit, if I knew it would, I'd back the chip right down to 600...=)

I've been running my PIII 700 @ 994 MHz since October with the core at 1.95V. Before that it was at 1.9V running at 970 MHz since July. I've got an Alpha PEP66 which keeps the temp at 34C max. With good cooling, it's no problem.

[badxxcow]

so far so good..been on 1.95 for the second day..idle temp is 23!!! pretty low...weird. yea that default burn in sounds possible..but yea i cant bear to see this thing at 566 =p how long you think i should keep it at 1.95 before trying to bring it down to 1.85 or 1.9? i havent ran the hard cpu programs all day..(seti etc.)..its just been on for about half the day..and wen im using it.

[markedmundb]

There's no need to bring it down to 566 to burn-in. I ran mine (also cc0 566) for a week (non-continuously) at 2.0v at 808 (the max of my abit Slocket) to burn it in. Now running in Soltek slocket at 850 w/1.8Volts. Temps never went over 25*C, at 100% load...

Previously with my cB0 celly (before it died) had to burn in at 1.9V at 850Mhz. Ran Stability tester for 2 days solid with that. Stable at 1.8V also.

[Phil]

the reason I said to bring it down is becasue burn-in's work best at lower temp's higher voltages, but at the end of the day it's alldown to opinion, I read an article explaining how the burn in effect is supposed to work and it suggested what I said but it's not definately going to work

[badxxcow]

ive realized something strange. my comp only comp only crashes wen i play counterstrike with oced cpu. i played quake3 and it was all fine. my stability tests were all stable too. so why is counterstrike dying?

[Phil]

Do you have a geforce or any other card with a TnL unit as quake 3 uses this so won't be stressing your cpu as much where as counterstrike doesn't use the TnL unit so depends on the cpu a lot more, I know on my computer with my tnt2 ultra that even if every other stability test passes the moment I use opengl if I have overclocked too far It will crash but D3D is fine, have you tryed CS with D3D?

[badxxcow]

yea i did but its unplayable..the frame are spiking. im running a voodoo3 2000pci ..not oced..with wicked GL drivers installed. this is so bad...i wanna play counterstrike? will buying a geforce2mx solve the problem?

[Phil]

I doubt that changing it is the only way to solve it as you are at a spec bus speed so I would say it is something to do with the chip, I presume it doesn't do it when you aren't overclocked?

[badxxcow]

yea its counterstrike is stable wen not oced at 850..is stable at 707..but that doesnt explain why only countestrike crashes.and nothing else..not even quake3..which is a newer engine than the old quake2 engine (halflife)

[Phil]

well as it only does it at the higher speed it is probabally a heat issue, how are you measuring cpu temp becasue if you are using the internal diode then these are sometimes inaccurate but always by the same amount. what heat transfer compund are you using?
oh and halflife uses the quake 1 engine but there is barely any original code left as they pretty muth changed it all which probabally explains why it's so slow.

[badxxcow]

well temp readings seem fine...and cs is not slow for me..i get 99frames. ill try to reinstall later. im using the thermal sensor that came with my be6.

[Phil]

exactly you only get 99fps at 850mhz and I bet that can drop as low as 30fps in busy scenes, even q3 doesn't run as slow as it and when you cosider that quake 1 runs close to 300fps on my system it bugs me that a game using the same graphics engine onely runs at an average of 120 and goes as low as 30fps, on my p2 233 it only ran at about 40fps and went as low as 5fps which was unplayable which is out of order when that is more than 2X the speed of the minimum spec

[badxxcow]

er no..i guess you didnt know that CS is locked at 99fps dude...
and i get around 60 fps in a battle..not 30. quake3 runs fine..even though frames are lower because of the newer engine. well counterstrike SUGGESTs getting a 333, if u bought the CS retail. i still dont know wats wrong

[@crilicM@n]

1.95, yeah, bit high... But the life expectancy of the cpu probably will not be diminished if you use a cooler software together... Maybe with a bit more of help in the cooling shall help you to lower the voltage... I don´t know exactly where are you know in the globe, but be carefull with the summer (if you are in winter), couse the 1,95v may heat up a bit more later and bring instability where there was only peace of bits before! GLuck

[badxxcow]

thanx i lowerd it back down to1.7 becus ei realized eerything is stable except counterstrike..i dont know why that game wont be stable at this speed. anyone know why?

[@crilicM@n]

Sometimes some games don´t like to runin oc pc.. It´s like the big zip files problem: Some pc will not zip huge zip files when overclocked! Beside everything is stable...
I can run quake3 without problems since i cool my videocard otherwise it overheats and freezes the pc! (****y original heatsink without fan.. hmmm) Cooling it let´s me play quake ok... But Starcraft will freeze randomly beside anything I can do... There are some diferences in games engines and some stress more the pc than others, not always related with the most fps rate game etc...
