problem is with you or you rig...
my test rigs have been running with no issues for over 48hours... (1070x6)only has 1 psu.. (1060x5)only has 1 psu.. (1060x4)only has 1 psu.. (1050tix1)only has 1 psu..
Maybye they are ovecrlocked too much, but when i mine on ccminer same alghoritms that whant to benchmark everithng is great, iv passed benchmark even in nicehash miner to test this setup.
Maybye its some kind of problem in my win 10 system i have no idea.
