Overheat? with Bad Company 2?

[jsrudd]

I've got a p6t with a i7-920 C0 stepping and 4850 crossfire. I recently updated my bios after reading that a newer bios for my motherboard improved overclocking for some people. However, I forgot to write down my old setttings so I'm having to start over with my overclock from scratch. I've currently got by bclk at 166, my vcore at 1.2900, and my qpi boosted to 1.30. It can survive about 30 minutes of Prime95, though I've never tested more than that.

I recently installed Bad Company 2 and I've been playing through, however my computer keeps crashing giving me errors like fatal hardware error and processor failed to pick up the clock or something like that. I boosted the vCore to what I have above (1.29) and then I could play alright, but my computer just shuts down without giving me an error message which I think is an overheating problem. My 4850s are getting to 113 Degrees C.

I've got a pretty good about of cooling with the Scythe Mugen 2, and 6 120mm case fans. My case is the Cooler Master 690. What gives? Any ideas?

You may want turn the fans UP or get better cooling on those cards.

What are you max load temps when you ran P95 for 30 Minutes?

113C?!? A CoolerMaster 690 with 6 fans should have ample airflow to keep those cards from getting that hot. Is there a chance you have all of your fans acting as intake fans? I just can't visualize that much hot air building up in that case.

Just for starters why not try a single 4850?

The fans are at 100% and I've got a slot cooler blowing on them! My max load temps running prime95 were 65-67 depending on the core. But that was before I bumped up the voltage from 1.2825 to 1.29 because of crashes.

And until you get your instability in check, run everything at stock clocks... GPU and CPU. Otherwise, you're just wasting our time and yours. Overclocked components are just another variable in an already complicated equation.

I have three pulling air in from the bottom / front / side and three blowing out from the back /top. Should I have a different set up?

It was solid at stock clocks. I never had a problem until I stepped up the overclock.

 

[rodney_ws]

That sounds fine... I just had this mental image of all 6 fans acting as intake fans and your case bulging outward from all the air you were pumping into it.

113C just sounds WAAAAAAAAAAAAAAAAAY too high. I know that most modern Nvidia cards are rated to run at 105C, but no one in their right mind would feel comfortable running them at those temps 24/7... and you're at 113?!? I'm not sure if ATI posted their maximum temps for that card or not, but if that's above the maximum, it's gotta be RIGHT at it.

I couldn't find that information on the AMD/ATI site... but here's another forum discussing 4850s and maximum temps...

Notice no one is saying that 113C is ok.

 

[tuffluck]

where do you live, the sun??????????? 113C should be generating smoke!

seriously that has to be some type of a record. i would definitely not OC those cards and try running some tests and see how hot it gets again.

 

[jsrudd]

The cards came moderately overclocked like 20 mhz or something. They're really close together like 3mm because they each take up two slots because of the heat sink on them. I'm really more concerned about the heat from my CPU because I've had to set the voltage so high. Its only running at 3.3 ghz and I had to crank it up to 1.29v.

Im running A simlar setup As you, Same Case And 1 Sapphire HD4850.
I've Got 8 120mm's And my gpu temps were around 90'C with a Serious overclock (GPP@ 775MHZ RAM @1200MHZ ) I thought those temps were unacceptable so I invested in a Zalman Heatsink/Fan Combo. This brought the max load temp down to 67'C. The Zalman Heatsink is also Smaller Than The Sapphire One

I just bought two of these online. Hope I can get the same results you have.

Good Luck! I wouldnt try for the Same OC though. I've Been Very lucky with my Card acctually reaching that OC. Remember that you are also using crossfire so the temps will be higher

Keep Up the good work and Good Luck
