Hello,
It's summer in Europe now and my Vega are running really hot now .
I have 21 Vega ( 3 RIG ) in one room running at 1950h/s but at 75-79°C, room temperature is more than 40°C now.
I'm trying to find the best setting for ultralow consumption for this summer even if I lose some hashrate.
For now I'm running at 1222 core and 1025 memory on Vega 64 and 1222 core and 900 memory on Vega 56. Both at 825mV Core and Memory. ( Average 1680h/s). I'm now arround 70°C on each card.
Did someone find better setting for lower consumption ?
I am in the same situation. I am balancing hashrate with temperature, too at one of my locations. Here is what I use for Vega 56. Make a .reg of the following for each of your GPU's:

Now with OverdriveNTool, try this on each gpu:
[Profile_0]
Name=Gpu1
GPU_P0=402;800
GPU_P1=692;880
GPU_P2=772;880
GPU_P3=842;880
GPU_P4=904;880
GPU_P5=1262;880
GPU_P6=1212;905
GPU_P7=1407;935
Mem_P0=167;800
Mem_P1=500;800
Mem_P2=800;880
Mem_P3=900;900
Fan_Min=2700
Fan_Max=4000
Fan_Target=75
Fan_Acoustic=2400
Power_Temp=70
Power_Target=-22
That's about as low as my Sapphire's can go. Of course, YMMV.
