DX10 games and BSOD

Halo2 vista, Lost Planet demo and World in Conflict beta are the 3 DX10 games I have at the moment, Lost Planet is the ONLY one that has not given me a random bluescreen yet. Game performance is terrible in all DX10 games with SLI enabled, but on one single card works well (until they crash). The error is almost always a bluescreen of dxgkrnl.sys (directx graphics kernel) anyone else here have a SLI rig and Vista x64 and similar issues?

AMD FX62 Processor
2x BFG 8800GTS oc 640mb graphics cards
M2N32-SLI deluxe Mobo
4G Corsair DOminator PC6400 C4 Ram
WD raptor 250g SATAII hard Disk
Windows Vista Home Premium x64 edition

You don't have problems with DX10 games, you have a stability problem in general, because Halo 2 is NOT a DX10 game.

SLI was always a nice and expensive troublemaker, and it's twice the problem in Vista. Try latest nvidia betas, they may help.
I have 8800GTS too, but not in SLI, I don't have Halo2 or WC, but LP demo runs absolutely flawlessly on my system. I used 162.22, but I had to to switch to 163.11 beta because of Stalker, which was crashing with 162.22.

Yep Update to the latest Forceware.
Also last i heard SLI in Vista was broken
Dunno if Nvidia has Fixed it Yet or not.

Try the Latest Drivers and let us know.

SLI is definitely available in 162.22 but not quad SLI, this is still not supported.
