Thanks @MinersRus .

I finally made my 6x vega 56 works. They are modded with vega 64 bios. No soft power play table. Miner is SRBMiner 1.7.0 and driver is 18.10.1

I follow the instruction here.  

https://www.reddit.com/r/MoneroMining/comments/9pwedo/guide_to_reaching_2k_2020_hs_on_cryptonight_v8_on/

except the intensity is set to 120.
Total hash rate is 11900 H/s and the power on the wall is 1250w. Isn't this power consumption kind of too high? or it is normal for v8?

That actually is pretty good. V8 is much more power hungry.

Your power is 208 watts per Vega 56. My seven average 225 watts.

Can you provide what your Core P6/P7 frequency/mv are set to and the MEM_P3 frequency/mv is. Thanks



Here you go.

GPU_P0=852;800;0
GPU_P1=991;900;0
GPU_P2=1084;950;0
GPU_P3=1138;1000;0
GPU_P4=1200;1050;0
GPU_P5=1401;1100;0
GPU_P6=1536;1150;0
GPU_P7=1552;840
Mem_P0=167;800;0
Mem_P1=500;800;0
Mem_P2=800;950;0
Mem_P3=1100;875
Fan_Min=2750
Fan_Max=3500
Fan_Target=65
Fan_Acoustic=2400
Power_Temp=75
Power_Target=0

Thanks, I changed my settings to:

Min  P6: 1352 MHz @ 880mv
Max P7: 1552 MHz @ 880mv

Min/Max M3: 930 MHz @ 875mv

The one problematic Vega 56 I still have to run at 985mv on the core.

Doing the above settings on the other six saved me 30 watts while adding 165 H/s.

I plan to do additional tweaks when I determine the above is stable long term.

Current systems are stock reference Vega 56's, Stock BIOS, no soft PP:

System #1 with 3x Vega 56's and i3-4130

GPU #0: 1932 H/s
GPU #1: 1911 H/s
GPU #2: 1922 H/s
--------------------
             5765 H/s
i3-4130     72 H/s
--------------------
Totals     5837 H/s @ 655 watts at the wall = 8.9 hashes per watt

System #2 with 4x Vega 56's and i5-4570

GPU #0: 1869 H/s <--- problematic Vega 56 @ 985mv, if it stops hashing all stop hashing and system locks up requiring hard power off
GPU #1: 1900 H/s
GPU #2: 1910 H/s
GPU #2: 1899 H/s
--------------------
             7578 H/s
i5-4570    197 H/s
--------------------
Totals     7775 H/s @ 888 watts at the wall = 8.75 hashes per watt
