I have a rig with 6 x sapphire nitro+ oc rx 480 8gb cards and using a modded bios from eth I am getting: - 1000h/s for about 910w at the wall Can we get more h/s from this gpu and less power draw?
I have the exact same cards, 7 of them in 1 rig. 1050H/s 780 Watts at the wall.
You need to underclock and undervolt.
I have now with modded bios from eth gpuclk 1150 memclk 2150, gpu core voltage -100mv 6 x rx480 - 930h/s - power draw at the wall 700w If I try to lower gpu or mem clock I get hashrate drop

5 x rx480, v4 used with -i 0, better than with -i 2 - 378 h/s - 700w

Hi all,
I have 5 x rx 480 8gb sapphire nitro+ oc. With claymore's zcash v3.1 and I get the following results: - 700W power usage - 310H/s so roughly 62H/s per gpu
Any idea how to improve hashrate and decrease power? Thanks
