I’ve tried the stable, and the two latest builds (standard and gooseberry) and I keep getting the following error anytime I attempt to use GPU Compute
CUDA error at cuCtxCreate: Invalid source
Hackintosh
CPU: i7 4790k 4.00Ghz - 32GB - SSD Harddrive
GPU: 2x SLI EVGA GTX 970 ACX
nVidia Web drivers installed
CUDA Installed
Blender preferences show CUDA option and correctly identifies the two GTX970

Hi, I am only guessing but does Cycles GPU work with one card?
Cuda apps also does not like SLI, you should disable it in driver settings or hardware wise.
Cheers, mib

Cycles w/CUDA works with SLI in Windows7 just fine.
Also in Blender Preferences you can choose which card (or both “x2”) I’ve tried selecting a single card, as well as both and get the same error.
