e4500 Overclock Situation

So I had my e4500 at roughly 3 ghz on the stock cooler for awhile (266 X 11).

Then I bought an AC 7 Pro to try and squeeze a few extra clocks out of it. I got it almost to 3.3 ghz and then decided to put it to sleep, upon trying to wake it (running vista) it refuses to show video, then you do a restart by hitting the button on the case and it will not POST. Same goes for turning it off and then on again 10 hours later, it will not POST.

I lowered the multiplier to 9 from 11 to raise the FSB to give the system and ram more bandwidth. Right now im at 9 X 333 because I turned it off last night and it wouldnt keep the OC settings this morning.

However, I can have it do Orthos Blend for 12 hours with no problems. And at the 11 X 266 overclock, putting the PC to sleep was not a problem at all.

The mobo is a Ga-p35-DS3R running an ancient Bios of F6, maybe that is the problem?

I have 2 GB of OCZ ram, an 8800 GTS (old ones) and the PSU is a 650 W antec.

I'm locking the PCI clock, all the settings in the BIOS seem to be right, but turning it off / sleeping make it go crazy.

Any ideas?
 
OCZ RAM usually requires pretty high voltages. Are you giving the RAM what it wants voltage-wise?
 
Ya, I've got the ram running at 2.2 V right now, which is the max that keeps the lifetime warranty intact.

And when I said PCI clocks in my original thread I meant PCI-E.

I'm giving an extra 0.1 V to the FSB and MCH as well.
