Hi Guys,

Im having problem with one of my XFX RX 580 cards. For some reason its mining slower then the rest, its starting like the rest with 31,4 mh/s and then after 1 min slows down to 23-24 mh/s and goes like this all the time.

Im running my rig on Win 10 drivers from December 2020. I have this rig for 3 years, it was ok at the begining, then the problem occured (it was times when mining was not so profitable) so i put that one card that slowed down to my personal computer for gaming. When mining was more profitable i again put it back to my rig - it was already on claymore 15 and....the card went like all the others - 31,4 mh/s. It went ok for months to time when claymore stopped working properly and i had to switch to phoenix - that one card immidiatly started miniing 24-25 again....

Now i switched with big hopes to MoreEpochClaymore 1.9 and the problem still exists. 5 cards go 31,4 and one card 23,5

What can cause the problem ( I tried to switch cables, risers...nothing helps. Still that one cards slows down after 1 min to 23,5
