Help with 380x on Sierra 10.12.3

Hey everyone,

I am trying to get back into hackintoshes after a very long hiatus and am having issues with getting my graphics card to properly function under Sierra. I have tried for hours, but am still lost as it shows my graphics card as:

ATI Radeon R9 M295X 7 MB

instead of the 4096 MB of VRam that it has.

My system specs (on this) are as follows, although I plan on swapping back my 4790k soon as well, but I doubt the CPU has to do with this:

• Asrock Motherboard
• i3-6100
• 32GB DDR4-2133 RAM
• 380x (have tried with two seperate ones and still same issue)

Please help!

Thanks
