Which miner, which flags, which driver, which SDK?
The golden settings for a 5850 are usually 10.11 driver, 2.1 SDK, phoenix miner, phatk kernel, VECTORS BFI_INT AGGRESSION=13 FASTLOOP=false WORKSIZE=256
Aggression can be dialed down if you use the computer for anything else. Worksize should be tested at 128 and 256.
