In "About this Mac" it says "AMD Radeon R9 290 5MB" instead of 4GB or something like that.

Hello, is there any way to fix this problem?

I installed Yosemite using Clover and everything is fine but video card. Everything is slow and I have to use my Intel GPU to have some smoothness.

I already injected ATI and its ID with clover, installed edited Kexts but it's still the same, except if I don't inject video card stuff in Clover, it just says "Monitor 5MB"

Thank you for your help and sorry for my English

Hi, thanks for the reply.

In 10.10 it was necessary to inject ATI. From 10.10.2 as I read in a post on reddit, it is not anymore.
But for 10.10.5 I can't find any news to know what to do.
Is there anything I can do about this VRAM thing?

Did you verify that the spoof actually worked? I think you'll need a gfx section in your dsdt (can be added automatically in clover). You should see the R9 290X device ID in System Profiler.
I tried by putting 0x67B01002 and even 0x67B11002 in Devices section on Clover Configurator with Inject ATI on and off too. Actually, I notice something different injecting ATI, because it seems a bit faster but it's always 5MB.

What should I do exactly to follow your advice?
