ASUS P5B-Deluxe; Problems & Fixes

[satandole666]

I've been running into a problem for a while now and it has happened on all 3 P5B series boards I own.

When my FSB is heavily overclocked (say 450+), during the boot process sometimes my video card isn't recognized. This gives me a blank screen as it boots through Windows.

I can fix it sometimes by powering off the computer, then the PSU, and restarting. However, lately it seems like the problem is happening more and more often (I am also pushing the FSB harder and harder with the E8400).

I think I might have figured out what the problem is but I don't know how to fix it. I lock my PCI-E frequency at 101 regardless of what I am doing. However, I remember reading somewhere that the P5B series behaves better if you overclock the PCI-E frequency along with the FSB.

Can anyone give me any insight into this? It is hindering my ability to run at higher speeds as it will take anywhere from 6-12 boots to get into windows. Half the time it does boot it states "overclock failed" blah blah blah enter the BIOS,even at settings known to be 24/7 stable.

Thanks.

Just a little more info, I've tried swapping video cards and it doesn't fix it. I've also searched this thread and didn't come up with anything...that and its kinda hard to sort through 186 pages or so.

EDIT: I guess it won't display my sig yet. Hardware is...
