@claymore

Need you help please.

I installed 3pcs of RX560 with fresh install of ubunta. I follow instruction of http://www.cryptobadger.com/2017/04/build-ethereum-mining-rig-linux/.

Everything is fine except only 2 card is running. The script can detect GPU0, GPU1 and GPU2 (in purple word). However, only GPU0 and GPU1 is working.

Script as below and the configue.txt is default empty setting.

#!/bin/sh
export GPU_MAX_ALLOC_PERCENT=100
./ethdcrminer64 -epool eth-us-east1.nanopool.org:9999 -ewal 0xxxxxxxxxxxxxxxxxxxxxxd/Miner01 -epsw x -mode 1 -allpools 1 -tt 68

could you please advise ?

I believe it's not a miner issue, I had kinda same issue with rx570 on Ubuntu, like fan on 1 card wasn't working, then hash rate on 1 card was significantly low compare to others. So I played(plug to diff pcie ports and used diff rizers) with port on motherboard and rizers, and now it's fine and stable.

Further with my issue, i plug again the 3pcs RX560 which is running fine now. However when i plug 6pcs of RX550. It can only run GPU0 and GPU1. I try to remove from 6pcs to 5pcs ..... until 2pcs. It is also running GPU0 and GPU1. Same setting of 3pcs of RX560.

Anyone can help ? I do think that it is related to the claymore script ....etc since my start.sh script is the same. It works on 3pcs of RX560 but not work on 3pcs to 6pcs of RX550.

Just to know... do you enabled the 4G decoding config in your BIOS? I'm using windows and I had to enable this config to use more than 4 gpus, I don't have sure, but I think that you need to enable this config in linux too.
