I'm not sure if I'm doing things right, but every time I tested swap 1750 timing to 2000 or used Ubermix 3.1 timing to 2000. After the restart of the PC, Windows gets 640x480 resolution and what I need to do is uninstall Crimson (running v 17.4.3) and install it again. After that I can rewrite to its orginal rom. Not get this to work at all, running it on a quite old motherboard, could it be the reason?

Have two ASUS ROG STRIX RX 480 8GB, running around 24MH/s stock each and both are Samsung memory



Appreciate all inputs to my problem here!
