I have 4 GPU NVIDIA GTX 1060 6 GB working. VRAM Hynix.

Yesterday I change the OC setting to:

60-70 power
-200 core
+800 memory
40% fan (+ domestic fan straight to the GPUs)

Before this I was performing 15-17 mhz/s
After this I was performing 18.5-19.5 mhz/s.

This was last night today mid day I checkd from work by teamviewer and I saw that 2 of the GPUS where fluctuating between 0 and 18, but there where never 4 GPUS working at the same time.

My hash rate drop from 73-76 mhz/s to 36-39 mhz/s.

Any one can help me pls!!?

I've observed this after a few days of it running stable. I think it's either the 60%tdp, shit memory or temp. It might also be Claymore after a few days of mining. I would go with tdp first try increasing it and see if it improves. If not lower the memory clock.
