i have got zotac mini 1070 ..why my hashrate drops with new dag .. it is 8 gig memory
I guess you're on win 7.
You have to upgrade 7 to 10, or use a Linux OS.
I've had the same problem with my 1070 rig. I just downloaded the "Windows10Upgrade9252.exe" on the Microsoft web site. (no serial requested.)
Everything works better for me on w10, even with some algorithms crashing under win7.
