R9 290 TRI-X OC Frame Buffer

[jura11]

Hi guys

Not sure if you could help me with patching the framebuffer,currently my GPU Sapphire R9 290 TRI-X OC is recognized under Yosemite as R9 290,but only HDMI is working and would like if its possible to have multi monitor support

Here is my extract from R9 290 BIOS

I guess you are on a hackintosh and inject a framebuffer (which one)? Did you try with standard RadeonFramebuffer?

Hi there

I'm using right now Yosemite 10.10.3 and FB I'm using "Baladi"

Which one is standard RadeonFramebuffer?

I can post my Clover settings if this does help,but really I'm stuck,I can't use two monitors,but only one with which is connected via HDMI

Thanks,Jura

RadeonFramebuffer is the default one when you don't inject a framebuffer.
Try to disable ATIInject or just overwrite "Baladi" with some random garbage.

btw, anyone got 290(x) working in 10.10.4 ?

with self-init I can see mouse pointer for a moment then it goes black screen.

Aha,then I will try that and will post the outcome

Thanks,Jura

Hi there

Not sure,but I've seen few guys tried that and they seems reverted to 10.10.3 as they have few issues with this,I'm still on 10.10.3 for now

Hope this helps

Thanks,Jura

I have same issue via DP.

But works fine on DVI. DP isn't it's friend in 10.10.4
