Alright I am experiencing a very bugging issue. Today I added a second 7950 and started hashing away BUT as soon as the first card starts the khs for the second one dropp by 70-80khs..System specs:
MB:Asrock 970 Extreme4 PSU: Seasonic 750w VGA: 1 - 7950 Sapphire 2 - 7950 Sapphire Vapor X 8GB 1333 AMD drivers: 13.1
Card N1 is in the main pci and the Vapor is in the second x16 for now. Settings in Guiminer are identical ( 7950 high usage ). Trixx settings:
Card 1: 925GPU/1250M/0.962V - 550khs Card 2 ( Vapor ) : 925GPU/1250M/0.962V - 560khs
Any ideas?
Thank You
EDIT: I am seeing the load on the 2nd GPU slips to 70% and then back up....Load only varies on the 1st card is working
