Problems with AMD graphics card

[jubilein]

Hey everybody,

i've got some problems with my AMD Radeon R9 390.
Everything is working well, but the screen is flickering.
In the options i saw that OSX is using just 5mb of my vRAM.
But how can i change it? I already tried to install the .ROM file of my GPU,
but i did not know how it works.

Can you help me?

Thank you!
Robin

Some ATI Radeon Graphics cards have problems. You may want to check this guide out. Radeon Compatibility Guide - ATI/AMD Graphics Cards Hope this helps.

Thank you for your quick answer!
I already tried to do it with this guide. But most of the things did not work (or i did not understand them as well)....
