maybe with more gpus than one result is better. i only have one. so half of my total watt is wasted on the pc
It's not wasted , your memory and memory controller using it . Set the memory voltage to 950 , 925 , 900 , 880 with wattman. Find the stable settings where your not loosing from the hashing speed, and you can save a lot of extra watts .
I am talking about cpu - ram - motherboard watt. with only 1 gpu, half of the total watt are consumed on all the other components of the pc.
I am here right now with another rom and i am quite happy. dont think it can get much lower
