Overclocking issues

redSwirl · 10 Feb 2011 at 14:41

Hi I am trying to overclock my AMD Athlon X2 250. However every time I up the frequency using AMD Overdrive, or let the system detect optimal OC settings, I BSOD. Even a very slight increase causes it to Blue Screen despite temps never breaking 40 under load. I think I'm doing it wrong. Anyway my setup is:

X2 250 3.0Ghz
ASUS M4A77T/USB3 Mobo
Geforce 460 1GB
Windows 7 HP

Have you tried using the BIOS instead of overdrive? You can normally get better results.

Have a read through this thread:

There should be a lot there to help you.

thanks it turned out lowering the RAM frequency to 1066 was all it needed to restore stability. On another question, the very helpful beginners guide to overclocking thread says up the CPU voltage by a notch if you reach a FSB frequency that is unstable at stock voltage, however my thing is saying CPU VID is maxed at 1.4000v (as in I can't actually up the slider any more) and there is a thing called NB VID which is at 1.17500v that I can increase. Is the NB VID what the guide means by Vcore?

No the NB VID will be the north bridge voltage. That is different to the vcore.

I would try altering the voltage in BIOS. You may find that it is not capped there.
