XFX R9-280X not being identified!
2 2

Question

Hey guyz please help, I have an FX-8350 CPU and XFX R9-280X GPU but I cannot get graphics acceleration out of my GPU! In -v mode once there was a Vbios error! My GPU has uefi bios on-board (its written on the box) so can that be a reason that my GPU is not getting accelerated?

My GPU gets detected by mavericks in -v mode as "AMD Tahiti graphics accelerator in slot 1" but when I boot up to desktop in system information it says Graphics:Display(7 MB) What should I do?

@k2sheth try to boot with clover it may trigger acceleration

Hey I installed clover and atleast I get some name for my GPU but still no QE/CI coz it says Vram(Total)-7MB whereas I have 3GB!!

That means it's a frame buffer issue! How to resolve?

your GFX card will work OOB but it doesnt working this leads to wrong kext may be you dont have proper kext ,what connector you used for connecting through monitor ??

try vanilla installation with full kexts ,,.

Yeah man you are right! Its a kext issue! I don't have AMD radeon accelerator.kext and ati7xxxcontroller.kext but I installed them perfectly, so why isn't it showing up?

And which kexts are you talking about?

By the way can you please detail about kext installation, maybe I would be doing it wrong! Thanks

Will this vanilla install method work for my build,

FX 8350 CPU

M5A99FX pro r2.0

XFX R9-280X?

Should I put kexts for my GPU during installation of macpwn or after OSX installation!?

while making installer don't select option of backup graphics extensions/kexts 

 

make sure you have selected AMDFX kernel.

I had this problem with yosemite , xfx r9 280 dd black oc edition so what i did was dumped my gpu bios then checked it with vbe7 tool and wrote the subsystem id  down.

downloaded Asus HD 7950 3072 bios from techpowerup and changed the the subsystem id to the one i wrote down

Then save the bios, then flashed it with atiwinflash.

 booted up and it was perfect  :) gl.
