CPU temperature problem

[lill87]

I use auto because I got no clue what Vcore to take, CPU-Z says it's currently at 1.376v.

Okay, thats too high, becasuse cpu-z reports lower than the BIOS setting. Thats your heat issue. 3Ghz shouldn't need a Vcore change.

Set it at 1.35 and test it.. If its stable, drop again to like 1.3, retest, and adjust.

How do I know if its too high or too low, is there a way to see if it is?

To high and the cpu will run to hot.

To low and the computer will be unstable/crash/BSOD

 

[patonb]

To low it won't properly start. To high it goes BANG.

Set the Vcore under 1.37, and run it at load, use prime95 or intel burntest to check for stability. If it doesnt fail or lockup, drop it a couple, 1.34, and retest. just keep going.

I tuned it down to 1.325v and it seems to work fine stability wise, the temp is at 50-55C in full load. Thanks!

Btw, what's there to think about when overclocking my GPU (GeForce 8800GT)?
Do I only have to think about the temperature and stability, and what's a good temperature?

Currently my GPU is running at 50C idle and 62C full load.

You could probably lower the vcore more, but not bad.

Youre running alittle hot on the gpu... But yha temp and stability.

I just noticed something. Before I overclocked my CPU, my memory speed was 1066 1066 in BIOS. Now they are 800 800 in BIOS, why did it go down?

And according to CPU-Z program it says memory is PC2-6400 (400MHZ), but I have PC2-8500 (1066MHZ).

Just go into the bios and adjust your memory settings manually.

I went into BIOS and changed RAM Frequency from (800, 800) and upped it to around 1066~ but it just crashes so it doesnt seem to be working.

This is the info CPU-Z gives me about the memory:


I use these memory cards:
Corsair Dominator 4GB (2x2GB) DDR2 XMS2 PC2-8500C5, Click for more info.

Any idea on why it says that?
