Well I don't know about the OP, but this problem is certainly NOT "resolved" for me.
I bought a BFG GF6800GT some while back, fitted a VGA Silencer and did the 1.4v bios mod. I found it was a truly excellent overclocker, reaching 453MHz stable (but with the occassional artefact) and - more sensibly - 440MHz completely rock solid and problem free. This was all in my old DFI Ultra Infinity nf2 board.
A week or so ago, I upgraded to an MSI K8N Neo2 and Athon 64 3200+. Everything works perfectly apart from this single problem: the GF6800 lockups.
I cannot run more than 400MHz core on my GT without getting these lockups. I know I shouldn't complain about "only" 400MHz from a GT. But a 40MHz drop is quite a lot to have to stomach.
I have tried *everything* to fix this.
1. 2d & 3d the same, coolbits
2. 2d & 3d the same, edited the bios.
3. FW off
4. Sideband addressing off
5. AGP aperture 128, 256 & 512
6. AGP speeds 66, 67, 68MHz
7. CPU speeds right down. (I even tried running 5x200MHz CPU, and it still happens! Or I can run 10x260MHz CPU. It makes no difference).
8. different nvidia graphics drivers
None of the above had any effect.
But here's the fascinating thing. If I run 440/1120 at try something like 3dmark01, I will get a lockup *instantly*. It will then sit there, locked, for 10 seconds and then spring into life and continue.
However, I *never* get any lockups at all - at any speed - in Doom3, Quake3, Quake2, Quake. (I have tested all of them). This problem *only* occurs in Direct3d, not in OpenGL. Has anyone else noticed this?
Also, very occasionally - its happened 3 times now - instead of the classic 10-second-lockup, I get a BSOD STOP Error. 0x000000EA.
This is the good-old-fashioned nVidia Infinite Loop error. Remember those????
I am wondering if at the bottom of all of this is a low-level chipset driver bug (or graphics driver bug)?
