Dear Claymore
Please, pay attention on dramatically decrease hash rate with epoch growth.
I test it on my rig with 3 RX580 4Gb (use -benchmark key) and here are results:
epoch #120 ETH: GPU0 29.380 Mh/s, GPU1 29.532 Mh/s, GPU2 29.944 Mh/s
epoch #130 ETH: GPU0 29.146 Mh/s, GPU1 29.273 Mh/s, GPU2 29.700 Mh/s
epoch #140 ETH: GPU0 27.567 Mh/s, GPU1 27.664 Mh/s, GPU2 27.992 Mh/s
epoch #160 ETH: GPU0 21.309 Mh/s, GPU1 21.397 Mh/s, GPU2 21.666 Mh/s
epoch #180 ETH: GPU0 18.493 Mh/s, GPU1 18.509 Mh/s, GPU2 18.795 Mh/s

So very shortly we got decrease hash rate on 5% (between epoch #130 and #140).
Please fix this bug or explain what to do.

That isn't a bug. As epoch goes up, hashrate of many amd gpu's goes down. It is known. Cheesy

I run benchmark on RX480 8Gb and got the same results. So it's not depend of memory size.
Does this problem have NVIDIA cards too?
