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...
