What is the stock voltage on the E8400?

[Raider00657]

Hey guys, I hope i have put this in the right place.

I've been having alot of trouble with Windows 7 getting two or three BSOD every day. I think it could be an unstable overclock which was fine in xp but maybe its different in windows 7. I have had them whilst playing games and when closing games and after a long idle. I have also had them whilst listening to music.

I have overclocked to 4.0ghz at 1.24... volts but i may be undervolting as no one seems to know what the stock voltage is i have seen different answers everywhere and i can't find it on the intel website.

The memory is running at 1066 at 2.1v

any help would be apprecicated

Cheers Alex

The problem is probably with windows 7; you can bump up the voltage a little more to about 1.3-1.35 and still be safe with a stock heatsink. Monitor your temps; they shouldn't go above 65c under load. The cpu voltage listed in the bios will vary a little with each motherboard. Also be sure eist (speedstep) is disabled in the bios when overclocking.

Thanks for the reply. I have set the vcore to 1.3v. Also i don't have a stock heatsink so its running at 40 degrees idle 56 degrees under load. I have the Gigabyte EP45-UD3P

Are you running Win7 x64? Sometimes, a CPU that is just slightly unstable will be fine in a 32 bit OS, but run into trouble on a 64 bit. I don't think it is Windows though - I've been running the beta and RC on a wide variety of systems for quite a while now, and haven't had any trouble. Is it better with the higher voltage now?

no still blue screening

Download CoreTemp. Then look under "VID". That will tell you the stock voltage for your CPU. Stock voltages are different from CPU to CPU.
