The ATI Radeonâ„¢ HD 5970 GPU is currently supported in single-GPU mode only. It is recommended users only access the first device on an ATI Radeonâ„¢ HD 5970 GPU for GPU compute.
*****************************************************************************
Does anybody know if the new 6990 shares the same fate as the 5970 for GPU compute?
Does the following also apply here atom?
Well this is a Problem for oclHashcat, but we have that hack, that hidden environment variable "GPU_USE_SYNC_OBJECTS". Using it we are able to utilize the 2nd GPU fully. It has been tested several times. It works fine. However its unofficial.
