way lower hashrate on claymore than ethminer

[ppppp123]

Have 4 7970's, got about 20MH each on the ethminer test and 12~ each on Claymore.

Windows 10, latest AMD drivers (also tried 15.12). Would love to just miner with ethminer but it crashes.

any thoughts? I was told 7970s should pull roughly 20?

Yes its normal. Mine ZEC with your 7970's.

Yeah, maybe a year ago. 12 or so is the norm now. RX 460 territory so the 79xx series is officially done with ether mining.
