nVidia's forum has been down for some time so I thought I would post my question here.

I borrowed a gtx670 for testing. It would not run DVDFab's bluray copy program unlike the gtx570 or the gtx460 or any earlier CUDA boards.

It would not run setiathome either but it did run gpugrid stuff and milkeway and prime (as I recall?). I only had it for 24 hours.

Anyway, why cannot gtx670 run programs that work fine on gtx570, 460, etc. Maybe the nVidia forum is down because there are real problem with the 6xx series and not on account of the password hacking.

Nothing to do with Nvidia's forum being down, It's just that the Cuda_fermi app (which is a Cuda 3.0 app) doesn't work with 304.xx Cuda 5.0 preview drivers, of cause you'd have known that if you had looked in Number Crunching at Seti wouldn't you?:

GTX 680, NVIDIA drivers 304.48 (beta), CUDA 5.0 lead to Computation Error

I tried the 4.x driver with the 670 and it didnt work just like the 5 didnt work.
