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

-96mV. -15% PD. 1300 Clock, 1900 Mem. 900W. 1020H/s
