I am running a Mac Pro 10.6.8 64bit 12-core machine with two Q4000 mac GPUs and i just installed the new nvidia driver, 256.02.25f01, released today. Now my CUDA 4.0 development is broken. I reinstalled the display driver, then cuda driver, cuda toolkit, and cuda sdk but still i am getting this error,
/Developer/GPU Computing/C/bin/darwin/release $ ./deviceQuery
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
[deviceQuery] test results…
Press ENTER to exit…
When i check the current driver running i get the correct, 256.02.25f01 display driver.
PLEASE HELP, i need my results for thesis completion.
