Hi, I have this weird problem, on a 6 card RIG, 4 of the cards gives me a hashrate of 20mh/s (down from 27mh/s, they are 4gb cards so I think it is that), but the 5th card gives me 30 mh/s, but poolside it is 500kh/s. The 6th card is a vega which gives me 42mh/s. Any ideas why this should be? It does not matter how I swap out the cards, which card is used for display or anything. Also tried the whole eth_epoch 274,274,274,274,273 etc.
Hi!
What OS and Drivers are you using?
I had the same bug, only a visual bug. Card has not enough Vram for ETH, this card only hash with 0 - 2 mh. I had this problem on 2 of 10 rigs, all with same OS win10 and driver 19.7.4.
I don´t why 1 card has not enough vram, display gpu is the integrated gpu and all cards the same for me. I checked gpu z and i see that one gpu use more vram as the other cards.

But i think it is not miner problem, same is happen with lolminer for example.
