1x XFX BE ref - 95W (GPU-Z) - 30MH/s
3x PowerColor - 90W (GPU-Z) - 30MH/s
Total Power draw 735W on the wall
using Tighter strap
First I set to reach the target speed (30MH/s)
then lowering power limits down to the stable points.
Each GPU have different bios parameters.
Win 7 - Crimson 16.7.3 (Configured using RDP - no monitor attached)
if the total power is 735w and you have only 4 gpu then each one is not consuming 90w only...more like 150w minimum
yes gpu-z always show less than real power draw.
