Hi all!
I a newbie on this mining topics.
I bought 6pcs of Sapphire RX 560 4GB. With my friends we built up the rig.
We used Asus H270F motherboard we used 2pc of psu.
The windows find the 6 cards but after I start claymore one GPU hashing only 2.095 mh/s the others reach 12 or above. We tested the risers the cards the cables, we switching the parts everything! But the problem is always the same.
Have you got any idea what's wrong?
Can you tell me how can dual mining? If I use this in dual, the ETH hashrate will go down? How %?
Thank you!
Search for 4MH/s problem (560 is half mining speed of mainstream 4x0/5x0 cards therefore Your's 2MH/s). Connecting HDMI screen to low hash card should solve the problem. Connecting through TeamViewer and disable/enable graphics cards in Device Manager also is doing the job.
