XFX RX 470 4GB Elpida with eliovp's strap that's around the forum for long time with equal TRCDR/A fix, I make around 850h/s with claymore xmr 10.2 , and about 920h/s with gateless gate at 1170core/2000mem/875mv , at about 2-3-4 errors per hour. With claymore xmr 10.2 hashrate is stable with rare low fluctuations to 800-820 , with gateless gate 0.1.3-pre6b fluctuations are a bit more , but averages at about 920-925 , new gateless gate sharp gives me almost the same results , old gateless gate is based on sgminer , so hashrate is about the same as sgminer, for me a little bit more than sgminer-5.5.5-gm-nicehash-8.

edit: With the same strap, same 1170/2000/875 on ETH make 29.5mhs , eth and xmr are stable with these settings , memory can go up to 2050 before significant error rate , but stability goes down with it. Claymore xmr 10.2 settings -h 928 , gateless gate settings 896/8/2 , claymore eth 10.2 -dcri 8
