Ati radeon hd 7950 3gb oc sapphire

[quikblond]

Hi guys!

I recently configured my new pc (gaming & studies).

It's based on

Gigabyte Z77 UD5H + i5 3570k + Radeon HD 7950 3GB OC

I installed ML and upgraded to 10.8.4 but graphics didn't work.

I have to use nvidia gtx 610 silent with graghics enabler=yes to boot and work on 1080p.

I viewed the thread with 10.8.3 AMD 7XX series and configured my bios through the guide, but not worked.

Any helps?

thx in advance ^^

I'm not sure exactly what issue you're having, but I'm having a similar problem. I did a unibeast/multibeast (dsdt free) install of 10.8.4 on a GA Z77X-UP4 TH board using the onboard Intel HD4000 graphics and had no issues (other than the kext dance - remove the AppleIntelHD4*.kext before install and reinstall it after multibeast). However, once I plug in a GA HD 6850, booting gets as far as macosx_swapon success (white screen with gray apple log and spinning wheel that lasts forever). The card worked find on an earlier GA 68x series mobo with GraphicsEnabler=Y and the dsdt from the tonymacx database. It seems that UEFI mobos are problematic for ATI 6xxx cards? I've tried all framebuffers and all variations of AtiConfig, AtiPorts, PCIRootUID and GraphicsEnabler to no avail.
