If you're still using Novak's cgminer-gekko from like 2015, I highly recommend grabbing VH's current cgminer build from the 2Pac thread. He's got a Windows build linked from a post in I think page 107, not sure if it's been updated in the first post or not. VH's driver is much better, and the base cgminer (4.11) doesn't predate MSX. Not sure if that'll help but I guarantee it won't hurt.
Trust sidehack to remain supportive to his baby--much appreciated.
Yeah 4.11 didn't make a difference. I tweaked the voltage up (even though the miners were only spitting out about 1 HW error/day) and will monitor to see if that has any affect (I know that it shouldn't).
Weird.
