Make sure you hit enter after a change then F10 and enter again when you are all done. Make sure speedstep and C1E are disabled also and that memory is set to optimal. I've got my E8400 clocked 600 MHZ over and I think thats all I did. Hope you get it going.

read shdbcamping's post - he quotes that your processor is not overclockable in the 630 via the BIOS....

Thanks as I was wondering if I was the only one that could read my posts . I'm just passing along info from Chris_M to save some people some headache 'til this all gets sorted out.
Here's a link to fellow consumer's in your predicament... Start a revolution. It's how the last bout of refund offers happened. Spread the word.
unlink memory and fsb. Set the fsb to whatever 1400 or what not leave memory alone. Now go into the voltage settings and apply a manual voltage to the CPU and FSB leaving the mem and chipset voltage to auto.
Add .05 to what ever the default was to start. And see if you post.
I know i couldn't post if i didn't have both the CPU and FSB voltage set to manual values.
