What miner are you using and how much windows bloat have you killed off from background processes and is virtual mem set to 16Gb or more?
Using Nicehash miner, sorry I should have included that. I haven't done much to background processes and I haven't tweaked virtual memory. I have a 6x 1060 rig that's stable as a rock, I never did anything to the virtual memory on that one either. Is it worth a shot?
how did you connected your risers? use 4pin or 6pin never with sata and you need to increase virtual memory thats one of the most importand things
