Overclocking E8400 on Asus P5K-EPU MB, help...

I am failing miserably at attempting my first overclock with an E8400 processor on the Asus P5K mb. I have Corsair DDR-2 1066 RAM.

One of my problems is that the names of the settings in this MB's bios don't seem to correspond at all with many of the guides out there. It is quite possible that I am adjusting incorrect settings.

However, as far as I can tell, I did the following:

Adjusted PCI to 100
Adjusted my RAM voltage to 2.1

I'm leaving the CPU's voltage on AUTO, I believe, as suggested by many guides, and simply trying to up the FSB.

Even if I only go to around 350, the system refuses to boot. From what I have read, 400 FSB should be easy on stock speakers with my setup (I got a Xigmatek heatsink, as well.)

Any advice, perhaps screenshots of your overclocks with this setup, would be greatly appreciated.

Indeed, stock speakers doesn't affect your FSB.

I hope you mean PCI-E and not PCI, since setting he PCI to 100, if possible, will kill any PCI card if you have any.

My guess is also ram, since that's the number 1 culprit when it comes to system instability. Tweak the ram settings around, or better yet, set the ram settings to stock.

Try running the ram at 800. P5K has known issues over 800. Its kinda hit and miss.
