Hi!

I have a strange "problem". I have 2 rx570 (4gb) and 1 rx580 (8gb).

My miner's last 24 hours statistic is this:

rx570 = 940H/s (with samsung memory)
rx570 = 930H/s (with elpida memory)
rx580 = 1100H/s

Summary (with my cpu) 2995-3005 H/s.
I have 1,1,2 ignored and 0 invalid shares in this time.

My pool say, my hasrate is in the last 24/12/6/2/1 hours: 2000-2100H/s.

In the miner detailed statistic I saw this (accepted/invalid/rejected shares)

rx 570: 1301/1/0
rx570: 1292/1/0
rx580: 428/2/0

My 580 card has only few accepted shares. The hashrate is ok, the consumption, the core and memory clock are ordinary. Apparently everything is fine. But the accepted shares is very low.

What can cause this?
