ATI Radeon HD 4870 Driver For Mac tmhanser Aug 12, 2015 9:58 PM I'm having problems with Adobe CC 2015 Photoshop crashing on OS X Yosemite and I'm trying to determine if it's the driver that Apple installed. ATI Radeon™ Series Drivers. With PowerDirector 7 and ATI Stream and, anyone can edit high definition video, create an amazing movie, and encode it for playback on virtually amd radeon hd 4890 device faster than ever before. Performance tuning flexibility will vary from graphics card to graphics card. In this review, we'll be comparing the Sapphire Radeon HD 4890 1GB OC to. Caused by overclocking, even when overclocking is enabled via AMD software.
4890 and 4870 so similar so 4890 didnt even need special driver in osx, it was using 4870's drivers so plan is to merge efi part of 4870 rom into 4890 rom problems: 1) we dont know if there any checks for device-id in code of efi rom 2) bios rom of 4890 is slightly larger than 4870's, so need to relocate MCuC section to fit efi rom here is two roms for test, pc part is from msi 4890, since most 4890 is amd's design, the rom should work on other cards too in first rom I changed matching in efi part and tried to relocate MCuC section to second rom I also added small patch of efi code. Need to test both with macpro, and if possible with pc (to know if relocation of MCuC section done right) make sure you made backup of your rom and have a way to flash it if smth goes wrong good luck testing!
Netkas 4890 ROM working!!! With ATYinit out of extensions folder.and it still works!!! Netkas is indeed King for today. There are a couplde moments in grey boot screen areas where the screen 'breaks' for just a second, as if vertical sync off, but other than that it seems perfect. I was able to hold 'option' and pick a bot disk.a new thing for 4890 in Mac Pro.

Mine is an MSI 4890 1 Gig Most of questions are answered in screen shots. Will try WIndows shortly but it should be fine. Now to drag the 2407 in here and do a 2nd monitor test.
If it does second monitor, the XFX 4870 will lose out as 'top' ATI card. Mine is Quad 3.0 from first Gen.so link speed will be 2.5 til it dies. OK.moving over to 'the Dark Side' I'll be back with more news shortly. (unless Bill Gates takes me) IM BACK- Works fine into Windows In any case.runs beautifully in either OS once drivers are loaded. It states 'Crossfire Disabled (Unsure in Vista64' in GPU-Z but I'm in Vista64 so hardly surprising.
If anyone is losing sleep over it I can try Crossfire but I have every reason to believe it will work 100%. Screen glitches in grey at first grey screen, and then into the Grey Apple screen. Perhaps getting clocks from EFI ROM and they are slightly 'off' what it loads from BIOS with drivers? OK.moving over to 'the Dark Side' I'll be back with more news shortly.

Does anyone know a design of experiments (doe free software for mac mac. It states 'Crossfire Disabled (Unsure in Vista64' in GPU-Z but I'm in Vista64 so hardly surprising.
