Bios won't allow me to change Vcore

[yaozer4]

Hello,
I have been overclocking my CPU but only mildly due to the lack of a very good heatsink. Anyhow, I still have plenty of room to OC but what happens is if I set my frequency to 390x8=3.12GHz when I go to stress test with prime95 it crashes me to a blue screen. It works fine at 380x8. I believe that it is because my bios forces me to set voltage control to auto in order to change the clock frequency. I'd appreciate some help as I plan on getting a new heatsink and overclocking a lot more.

Also, this is what I'm running
Intel C2D E6750 2.66GHz
Nvidia GTX 260
4 GB DDR2 800 RAM

Thanks in advance.

Motherboard???

Sorry, It's a Giga-byte P35-DS3L

And actually, I'm looking at info from HWiNFO and I can actually see that the normal CPU configuration was '2666.7 MHz = 8 x 333 MHz @ 1.3500 V' while it also shows my current configuration '3074.0 MHz = 8 x 384.2 MHz @ 1.3500 V'
So I can only conclude that the Auto setting in my bios isn't doing anything to voltage and that's why it crashes when i get too high.

Any recommendations for a better one? Preferably one that won't break the bank.

Asus P5Q, P5Q pro or P5Q-E.

So does that look like a winner?

That's an "Open Box" one which means it is either returned by customers or a used demo.

How about this one?

Cool, thanks for the info. I'll see if I can get the necessary funds.

Honestly man, i wouldnt be spending much on upgrades for that system. You will need a new one soon.

E6750 is still good enough for gaming especially when OCed to 3.4GHz which should be easy.

He is obviously limited in budget. Getting an i5/i7/PII will also force him to put even more money on the DDR3 RAM.

Please note: The power supply should contain an auxiliary power connector specifically for the graphics card.

True andy, thats just not a system that i would be spending mor emoney on JUST for overclocking.

Well I have been looking and I think I'm just going to wait and get a quad core for the same socket. But would that be wise? Or should I just wait and save up to get a new i5 with a new mobo and ram? I've been looking at these

I should be good though on my video card don't you think? I appreciate the advice and let me know what you think.

 

[andy5174]

DO save up and get i5 if you don't need a better PC urgently.

BTW, I suggest you get P55A series Gigabyte MB as it comes with revised socket.
