Hello guys,
Apparently problems there exist with Nvidia nForce3 250 and Nvidia 6800 GT combination. I have read a lot of forums, expose my problem to manufacturers, wrote to experts and until now I have not been able to find a solution. I got first an evga 6800 GT and actually an MSI 6800 GT 256MB AGP in combination with an MSI K8N Neo2 nForce3 250 Ultra mobo plus an AMD Atlon64 3500+ and the Aspire Chameleon 550w (+12V rail @ 36A, no problem!). My system pass memtest86, SuperPi and prime95. GPU core temps at 49-57C range, no problem. Well, I installed my VC and artifacts appeared on my desktop, fixed when I raise the Color Quality to 32 Bits(?) (I have a Samsung SyncMaster 710N @ 1024x768, 75Hz, 12ms TR). Then I went to dxdiag and neither DirectDraw nor Direct3d passed. DirectX cube frezees and reboots ocurring ocationally. I proved all of kind of changes: drivers, AGP apertures, frequencies and voltages, disabling/enabling BIOS features, Riva Tuner, Coolbits, Driver Cleaner, etc., and nothing. Inclusive MSI sent me a new mobo BIOS v1.62 and didn't fix the problem. I haven't proved to change the GPU BIOS because either I don't know if that one fix the issue or warranty is voided. Apply an RMA? I think that that doesn't solve the problem.
But I discovered something: lowering the Core/Memory clock to 350/800MHz (stock is 350/1000), artifacts disappeared even at 16 Bits, passing those tests.
Thus I got AQUAMARK=59657, 3DMARK01/03/05=21105/9956/4486, the last one at FPS as low as 1 in the hardest test. HL2 runs fine at minimal settings. I used 71.20 drivers.
I hope that, sooner than later, anyone can solve this troublesome problem.
Thank you so much for your opinion and attention
