Hey guys,
I had a couple 4870x2s lying around so I decided I would give em a try mining (I currently get free power from school so not concerned with how inefficient they are). Well I hooked one up, installed the proper drivers and sdk, and started up scrypt gui miner. When both gpus are active, I get 100% usage on gpu0 but only 62% usage on gpu1. Seperatly I can get 100% usage on either one, however once both are active, gpu1 throttles to 62%? additionally gpu0 isnt coming out of its power saving mode and so while its mining the clocks are stuck at 500/500 (should be 750/900) any idea why? Thanks
