Some xmr testing with sgminer-gm:
gpu0 xfx390 elpida 1250 strap copied to 1500, 1100/1500 everything else stock
gpu1 asus390 hynix 1100/1500 stock
gpu2 xfx390 elpida 1250 strap copied to 1500, 1200/1500 everything else stock
gpu0(x4?) and gpu2(x8?) are connected to mb without risers, gpu1 with riser. gpu0 is identical to gpu2 and can do same clocks but hashing speed doesn't rise. Default elpida is normally 20-40h/s slower than default hynix.
No under/overvolting, no finetuning, just simple copy and testrun.
