I have a XFX 290X and a Ref XFX 290 both hashing at ~60-65 H/s using Claymore 3.1 miner. I would like to overclock these cards and I tried playing with the Core Clock and Memory Clock settings but I didn't notice a change. I am using MSI AF and running Crimson 15.12 drivers.
Am I doing something wrong?
Thanks for your help!
