basically claymore is not longer supported and has not been for some time. your only real choice at this point is to switch to another miner.
Which miner do you advice to use?!
ive actually no idea at this point as im not running any AMD cards, sorry. but if youre running PhoenixMiner ok i know its been pretty popular. but thats more an observation, not advice per se.
Phoenix is easiest because you can use same commands for clocks and temps.
