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: Windows Registry Editor Version 5.00

I'm trying to find the sweet spot but it's hard. I'm the only one trying to use lower core frequency ? Is it possible to go bellow 825mV core?
