Hello Guys,

I am noob in mining and i am building my mining rig in win 10 64 bit. I have 2 MSI RX580 Armor 8G. For every individual GPU, i can undervolt/overlock the GPU by these parameters (single GPU in rig).

-cvddc 900 -cclock 1200 -mclock 2080. I verified in GPU-Z, it is working.

But if there are 2 GPU cards in rig, I found these parameters only applied in the first GPU #0, for the second GPU, it is working in the default clock and volt.

I tried the following command, while the result is still same, only GPU #0 is undervolted and overclocked.  

Just wondering if i did something wrong. Can anyone help, please?


setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
