Need some help. Besides the 580s I have a gaming pc with a 1080ti in it.
Lately I was using claymore eth miner.
Suddenly I get no hasrate and getting this message

GPU 0, GpuMiner cu_kd failed 77 (0), an illegal memory access was encountered
GPU 0, Calc DAG failed!
GPU 0 failed
Setting DAG epoch #177 for GPU0
GPU 0, CUDA error 77 - cannot write buffer for DAG

On ccminer I get> GPU #0: result for 00000000 does not validate on CPU!

I used MSI afterburner for several weeks without problem. The memory clock was higher I admit, maybe that triggered a lock?
Anyway I am now reverting to older drivers also I am using the default values on the GTX without OC or undervolt. nothing helps.
Tried setting the virtual memory but that was fine, nothing changed.

Any thought?

I will try today to swap the OS (just to change the SSD from the mining rig).
If that helps than it's some driver/OS issue.. I will reinstall Win10, if not I have one more shot with changing the PSU, after that I am pretty clueless.. games run fine though..

I don't get any supported clocks:
