Core i7-950 Overclocking HALTS

post #1 of 2
Thread Starter 
I have a hard time keeping my system stable i have a Thermaltake 750Watt PSu and my question is i got my computer to start at 3.8Ghz. But everytime i play a game for a couple minutes my computer shuts down. My videocard is EVGA GTX570 SC. But when i run PRIME95 for an hour it's fine... I just want a stable overclock for now... Here is my settings.

Intel Core i7-950 @3.83 x24 Bus159.9 @1.256V 58C -LOAD
Asus P6x58d-E
Thermaltake Extreme 120
Thermaltake 750Watt
Corsair PC3-1600 @ 1604 1.52V 8-8-8-24 2T

If you guys need anything else let me know but i'm hoping it isn't my GPU. I ran Prime95 for an Hour and no troubles. But when I play a game it BSOD's. URGH!

You'll need to run Prime95 for more than an hour to establish stability. Most of us leave it on overnight. Also try stressing your CPU with IntelBurnTest (v2.5, I believe is the current). OCCT is another stress program that works quite well.

Try enabling load line calibration in your BIOS (100% LLC if possible). Make sure EIST is disabled. Disable C1E and SpeedStep as well as TurboBoost. All of these features make your CPU voltage a moving target, and for overclocking you need consistency.

For 3.8 Ghz, you're probably going to have the most success with a bclk of 200 and a multiplier of 19. The 200 bclk makes it easier to keep your memory at the stock frequency.

Also, what kind of CPU cooler do you have?

Edit: I'm an idiot, lol. You should be able to aim for 4.0 with that cooler, not much higher, though. What kind of thermal interface material are you using? (TIM, thermal paste)
