Hello ! Thanks for looking at my question.
I have the rx590 8GB.
You can do an automatic overclock in the Radeon control panel.
If I do this, I get about 1640MHz (80 MHz more then base clock - 5% more) on my GPU-clock.
This is very stable and works excellent.
I checked if the overclock applies and stuff, and it does. (checked it with Unigine)
But this automatic overclock doesn't boost my VRAM.
So I tried to do the GPU-clock first of all manually to do the VRAM clock later.
But the problem is that the GPU-clock already crashes when the it is higher then 2%. (only 31.2Mhz more)
Does anyone know how to fix this? Or is this normal?
