I got what I thought was a good deal on 10 MSI RX 470 8GB cards, expecting ~22Mh/s ETH

Well it's more like ~18Mh/s. No biggy? probably the AMD DAG Epoch issue I guess...

So I tried some Monero mining and I'm getingt ~500H/s per card

Seems very low compared to what I've been seeing for these cards.

I want to put them all into the 13 GPU ASRock board but now I'm wondering if I should just return them...
