Hello guys, ive been having this issue of black screen.
What ive done was to
1 - donwload CPUZ and download the vbios file
2 - download morepowertools from igorslab
3 - open the VBIOS file on MorePowerTools and change the FCLK boost and frequency to 1/2 to my ram speed, in my case theyre 3200mhz so i put 1600mhz in FCLK.
This erases at all my crashes since the change, no more suddenly blackscreen while playing/browsing.
