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)

Did you change the timing strap in the bios or using other tools? The efficiency sees not no high as it is 735W for 120 MH/s.

yes i change the timing strap. about 150W each card

Is that dual mining? If that is solo mining, then 150W is quite high.

Did you change the memory strap yourself?
