unfortunetly, ia am a little green in those minning things,
try to build my own machine with 5 x rx 560 2gb, but after OS starts it shows only 2 of them working.
and not digging (i think becouse is 2 gb only - maybe there is some sollution?):

WATCHDOG: GPU error, you need to restart miner
Binary file (standard input) matches
i have RX OS instaled on pendrive,
little old MB - GA EP35 DS3P with 2 gb ram (maybe it is little short)
Good PSU - Enermax 1250 and cards connected with riser's
those two connected to full PCI X seems to works, but the others not.
maybe someone can help me
sorry for my English, still learning
regards

I'm fairly new to this as well, but I'm also mining on RX 560s, although they have 4 GB. I'd say that error message is pretty self explanatory - the DAG file won't fit in the VRAM as it grew over 2 GB at the end of last year, having sent most 2 GB cards back to gaming ... I believe I've seen a mention of a workaround, possibly in Claymore's instructions thread (
https://bitcointalksearch.org/topic/claymores-dual-ethereum-amdnvidia-gpu-miner-v150-windowslinux-1433925). Not sure if it can be implemented in the SimpleMining OS running from a thumb drive though, I'd assume it would need to buffer the DAG data on some sort of faster storage, so IMHO you'd still get a performance hit. Also your 2 GB of system RAM might be too little.
I agree a bit more concise documentation would be useful, and I wish the instructions for the most up-to-date version of SMOS could at least be found in the first post, it's really too hard to find anything useful in a single thread with 210 pages ...
