Why is the Stats reporting so low??

Been mining for more than 3 days now.

It happens to me once in a while but it is somehow annoying.

While mining - NiceHas Miner. 1.8.x - I sometimes see that the rate drops from the usual when I started it and when I check AB, I noticed that one of the GPU sensors is not responding. I have 5 GPUs of the same brand type.

When I check Device Manager, I notice that all are fine. But when I check each one in GPUz one of the cards will show "unknown"

What I would do is to uninstall(Delete the driver) the driver to one of the GPUs in Device Manager and then as soon as if brings back all of them I re fire my miner and all is well again.


Any thoughts?
