Hi everybody.
Firstly, thx for this thread.

I have a mb x370 gaming pro carbon and a Vega 56 (sapphire)
I manage to get a steady 1800h/s 1850h/s with the tuning from hallae

Now I bought a second card,vega 56 (gigabyte)
I can't manage to get 1800h/s on both. (I have 3100h/s)

I disable crossfire, and deactivate/reactivte HBCC each time I start.
On both card i'am with intensity 2016/1600

In wattman i notice one thing, on the second card I can't go upper that 920Mhz for the memory. ( but the first one handle the 950Mhz).
Do you think is a GPU default?

Thx for your answers!
