Wrong VRAM for my Video Card

[Swear]

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

There should be no need to use inject ATI (-> mostely cosmetic) or edited kexts (-> will be overwritten with next OS X update anyhow). Spoofing your device ID to match R9 290X should usually do it.

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 ******, 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?

As I said before, the card should work properly when you spoof the device id in Clover.

It does not. That's why I opened this thread...

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?
