Ok. Not a noob user then

I have been running HBM at as high as 1199mhz as well with the soc overclock but not getting 2500

What might change using a tv.... I know the drivers to make a difference between a monitor and actual tv but....
I happen to own the exact same tv but its fcking heavy and dont want start draging it to my rigs at the moment

First I connected the vega 56@64, installed the driver, then replaced it with 64, I think it's somehow related. After rebooting hashrate drops to 2000 and that would get 2500 I need to remove the driver, insert the vega 56 and so on
