Q6600 @ 3.8ghz - But plenty BSOD's

I said that many people on here including myself wouldn't feel that comfortable running 1.6Vcore through a 65nm chip for 24/7 usage.

But based on what evidence of CPUs failing? I've got 8 machines here in my SAP test suite, all running at least 3.6GHz and all are running 1.5V plus. They literally run 100% 24/7 and none of them is showing any evidence of problems. The early G0 Q6600's had much higher Vids that the current ones and most of them need big volts to hit 3.6GHz, let alone 3.8GHz+. I've never heard of a Q6600 failing after being overclocked, or even E8x00 and Q9x00 CPUs other than the first couple that were reported on Extreme Systems.

I didn't say they couldn't handle it, I said I wouldn't feel comfortable running it with vcore that high.

What i said was if he's prepare for another CPU then it's fine as just in case cos 1.6V quite high volt on air (not sure on water)

I'm running 3.4GHz with vCore 1.44375 and my temp already hit 71c so what would like with 1.6V?

under load my cores reach about 47c-50c, its just my vcore is at 1.56v

I'd say he has excellent cooling, so why is everyone trying to hold him back?

Do you guys drive under the speed limit?

WJA96...how many points you got on your license

temps are good yeah, im using a true 120 with push/pull config, both high cfm fans up to 97cfm 2000rpm (noisey if turned all the way up!) and i know not to exceed a vtt of 1.4v, 3.7ghz is very good i agree, if theres room for more i see why not. Im also using a GO revision which is the last one/best release.

Im happy going on into the 1.6v range, i just have certain doubts in the back of my mind, especially since ive been told i should only stay between 1.5v-1.55v

I know its only a few mhz more, its just tempting to squeeze it all out

It doesnt make a difference anyway what vcore you use, cooling it with air, water or phaser? Its still putting the same volt through it, my temps idle at 34c thats not a problem, just if i should put more volts through it

Edit: the Official SuperPi thread link doesnt work?

can you repost the super pi thread link?

cheers

would you agree with what they say here? http://www.xtremesystems.org/forums/showthread.php?t=207538

Why do you think 1.6V isn't OK?

Have a look at the Official SuperPi thread and you'll see people running Q6600's with massive volts.

That was only for short runs to be fair and in most cases on H20, Cascade. I can't provide a source but i'm sure i've heard of depreciating clocks @ high vcores.

Just seen your above post with regards to your SAP kit. Fair play - Are you working for a consulting company? If so, who?

not sure what you mean by sap kit if you were referring to me, and if so no i dont work for a consulting company

Hi toon_mad, I would highly advise downloading Prime95 and running the program for around 9 hours to test your system for stability. Also download CoreTemp to keep an eye on the temperatures. Whilst running Prime95, if the temperatures start exceeding 75 then you will need to start decreasing the VCore which will then probably result in lowering your FSB for the system to remain stable.

You say that there's no need for running Prime95 since you will never be taxing your system to the extent that Prime95 does. Even so, all it takes is a program to use your CPU ever so slightly more than it would normally or even a spike on the desktop which suddenly raises the CPU usage and your system will crash.

That's why it's important to run Prime95 so you know weather your system is truly stable or not and the below situation won't occur.

Ok, ive got my quad reasonably stable @ 3.8ghz, in XP im normally good for about 2-3 hours or so, as soon as i enter gta that 2hr stable drops to about 20 minutes if im lucky.

ok well ive been running prime95 for two hours earlier, temps were good at 57c or so, i had to cancel it and the program froze, had to restart the pc. not sure if its down to the program, windows or the overclock - temps were reasonable as i said.

I dont like using it, the program doesnt crash until i want to cancel it
