Update on the gpu miner

Going from 2 cards to now 4. Running 3 rx470, and an attempt to run a r9 380. Found out the 2 gb card can not mine ethereum algarithm. That is not enough memory... sadly!!! But now we are moving towards mining other coins because eth is so difficult... the hash rate is slow, we haven't overclocked anything either so it is semi slow... but we do have 4 cards running now so that is a plus...
