I switched from latest beta to latest WHQL, now stable in Crysis
 
4400x2 @ 2.7ghz. I could only get stock stable, if that with Crysis. I think with the X1900XTX I got around 7000 3dmarks. With latest drivers probably around the same, around 9850 stable in 3dmark, but not stable in games. No I didn't use NiBiTor. Just rivatuner.
 
I guess flashing the bios is similar to flashing my ATI X1900XT to XTX, basically at stock it'll perform faster, without needing rivatuner clock util? Not flashing it, but here's snap from that flash util.

Darn spoke too soon, not stable in Crysis :-( Fine in Tomb Raider though, and definietly smoother framerate than the 1900XTX (although I haven't played it recently, perhaps ati have improved drivers) in legend on outdoor scene (quarry) now at higher resolution smooth.

Not changing mobo/cpu...fine for a while yet.
 
It seems limited to Crysis (crashing) though, when I leave it at stock, and even OC for other games it's fine. Yes I've put the RAM sinks on. Crysis is patched 1.1, crashed. 1.2 still crashed.

When it crashes in Crysis it flickers for a second then a hang. Enermax Liberty 620W PSU.
 
Eh? PSU is fine. I've also noticed it's keeping 3D clocks when dropping to Windows, even though I've changed "Performance 3D" tab in rivatuner. When I go to 2D and change to stock, it also changed performance 3D mode..weird.

Dropped CPU overclock by 2mhz multiplier and seems to have sorted out crashing, played Crysis for a couple of hours...no hangs. My Palit 8800GT has no heatsink on the mosfets, unlike the images on google, they're towards the PCI black plate, and are bare. Is this normal?
 
Wish there was a automated clocking util, like the ATI thing...just a lot of time. Just leave it for a couple of hours and it slowly ramps up core/shaders/memory, writing logs off in realtime.. so when it crashes you can find out previous stable settings.
