Hello, i've begun mining, and i build a small cheap rig with a Powercolor Radeon HD 7970, which i just use for 24/7 ZCash mining via NiceHash.
But the problem is, that when i begin mining, it all seems fine, it tells me i get 270.000 sols, and im earning a stable 1,3$ a day, but then suddenly after a few minutes it drops to 40.000 sols?
I've also discovered that my Core Clock and Memory Clock decreases from
(Core Clock 925Mhz and Memory Clock 1375Mhz) To (Core Clock 500Mhz and Memory Clock 150Mhz)
Temporary fix for this currently is rebooting the PC, but the same problem then occurs a few minutes after!
Im really confused why this is happendning, and i really wanna get it fixed since it has a major impact on the income of my miner.
