I don't understand something to be honest; I mine for a few days at 95-96 MH (confirmed by the average on the pool), then all of the sudden I look and find that it's mining at 85-90, again with the pool average confirming that my values have dropped.

Strange thing is, I had GPU-Z open this whole time, there is no Temp throttling, the MSI Afterburner settings look good, so what gives?

I only mine ETH.

Also, what thickness did you guys use for the thermal pad on the memories? Is 1mm too much/little?
