What are you running your card at for mem/GPU/shader speeds ? What does BOINC estimate your card at in GFLOPS ? Estimated @ 117 GFLOPS Core/shader/memory 702/1512/1000 It would be 702/1550/1100 if evga precision was working... Zeus, As long as the result validates it shouldn't be an issue but something is causing memory usage problems.

Hey, after I installed 190.38, all went fine, but when replacing ' old' CUDART & CUFFT.dll for the 2.3 CUDA version, BOINC can' t srat. "client hangs . . .". Have to shut it down manually. How do I get the ' old' cudart & cufft.dll's back? Maybe I' m gettin tooo old?! ;-) ID: 921679 ·

But having downloaded and unzipped Cuda2.3rt_fft_dlls.7z What do I do with them? Just copy them to the program files\BOINC folder ? PAul [IMG][/IMG] ID: 921832 ·
