Does anyone have such problem - on Win 7, v15, drvs 436.30 and 441.66 and GTX1070 cards hashrate is about 22Mhash.... Tried to clean drivers with DDU and reinstall them, tried with/withous straps, w/wo OC etc.... On other algorythms speed is same as before, no change. And some months ago with older claymore all was fine, but now, with v15 such problem
upd: same issue on Phoenix miner, but all fine on nanominer and gminer.... can't even guess what it can be...
Confirmed, got the same issue on 1070TI. Problem is related to
ETC mining.
Hashrate drops to 17-20 MH/s when mining
ETC. Tested on Nicehash and Ethermine ETC pool.
Tried almost all avaiable miner software (Claymore, PhoenixMiner, GMiner, Ethminer 0.18/0.19a) and always got the same behaviour.
Probably this only related to Nvidia cards, or even Pascal family.
Also confirmed, win7 and GTX1070 low hashrate on ETC. win10 - ok.
