Hello 

I had version 20.4.2 amd drivers and 5.2d PH but today I lost hashrate. I decided to upgrade to 5.2e and update drivers to 20.11.2 but it still has the same hashrate. I lost 1-2 mh/s per card.

(1) rx 570 4gb 23 mhs (I had 25-26 mhs)
(3) rx 580 4gb 26.5 mhs (had 28-29 mhs)
Windows 10
Amd 20.11.2 drivers

Any idea?
