OCing DS3 rev 3.3

[HotGore]

Ok I can do 400 fsb fine and stable. The only problem is that when I shut it down, leave it for a few hours and come back to turn it on it will not post a 400fsb, it will just cycle, then disable the OC leaving me at 2.4ghz. Any ideas?

Highest voltage settings
Ram@800mhz and 0.3+v
CPU@ 1.475v
fsb@.3v
MCH@.3v
PCI-E@ 109mhz .1v

Firstoff some of your values are way out of whack.

PCIe speeds shouldn't exceed 105mhz unless you NEED them to (some boards require this, yours does not).

MCH and VFSB values are +.3v which sets them to around 1.5 each... This is a bit high, and dangerous to that board (they've been known to poof randomly). I'd set these values to +.1v each, and see if you're still stable at 400mhz.

Oh, and about 400mhz, try 401mhz... The P956 board applies the 1333mhz strap after 400mhz (I'm not SURE your board does, infact I'm almost certain it doesn't, or didn't when I was shopping for a conroe board) which might add some stability.

You shouldn't need your CPU voltage to be over 1.45 for that OC. If you do, I'd scale it back a tiny bit (unless your temperatures are ok of course).

As for the random no-boot error... What's your BIOS revision? Power cycling was a known issue on P965 motherboards, and was fixed for most boards through BIOS updates.
