1070 got 326 and 1080ti 502 on windows

What is a "cublas error (um_31)" and how to fix it?

generally speaking i have 1060 hash/s wih HiveOS , under win 10 i have 960 with same power limit / core clocks etc. Actually looking at cards on nvidiainspector they draw more power than linux reports. ( 120-140 W respectively for gtx 1070 ti / 1080 ). I have i7 8700 but it's running at 30 % under win 10 so it is looking good. Also the dependency over PCIE x16 slots / super strong CPU etc seems removed under windows. So my guess is that actually under linux they is still plenty of room for improvement and eventual + in hash there. Windows should also be capable of a bit more I am seeing that cards stay at 100% gpu load , but constantly fall to low loads . Still overall linux seems better for 1-2 GPU system and windows seems better for multi gpu systems.
