Ati 5870 Drivers For Mac
Yes it’s a day spent reinstalling your system. But for me it was all positives, no regrets whatsoever. I like El Cap better and so do my GPUs.
When i had snow leopard, software update made it work. Please assist. When did i ever deny the answer? Qq download for mac. I myself aware that software update should fix this issue from my previous experience with snow leopard. But it did not help with mountain lion. Just wanted to understand what could be the issue, and what 's the trial that i can make to have this resolved. I did try to remove the graphics card and put it back, but it was too tight.
Feb 13, 2013 Question: Q: ATI Radeon HD 5870 Driver for Mac OS X I have a 2009 Mac Pro with a default NVidia GeForce GT 120 graphics card AND the ATI Radeon HD 5870 as a additional graphics card which is hooked into my two external monitor. For amazing graphics processing power, the ATI Radeon HD 5870 with 1GB of GDDR5 memory is an ideal choice for visual creative, scientific, and technical applications. ATI Radeon HD 5870 includes three video ports: two Mini DisplayPorts and one dual-link DVI port. This software set also supports most ATI graphics built into many Macintosh models. It is safe to use both a retail product along with an existing built-in product with this single driver set.
(Special thanks to 'Pegasusrjf' for his input.) With the Radeon HD 5870 installed in the 2008 Mac Pro, I got three displays to light up and work with this setup: 1. 23' Cinema on the DVI port 2. 23' Cinema with MDP to dual-link DVI adapter on first MDP port 3. 24' LED Cinema with direct MDP connection to second MDP port Tried the same setup with the Radeon HD 5770 in the 2008 Mac Pro: Only 2 of the 3 displays light up.
I have no idea what caused the graphical glitches I saw under Sierra but they persisted no matter what Clover/DSDT/SSDT options I tried. As zero backflips were needed for the 5870 to work flawlessly under El Cap and the previous OS X gens, I have to conclude that Sierra doesn't fully support the 5870 anymore. Just the fact that it's not compatible with Metal seems to indicate that it's not a viable GPU moving forward for those who want to run the current and future versions of macOS. Which, frankly, no longer describes me. I'm currently running both Sierra and El Capitan on various Hacks here, but for my main workstation I’ve gone back to El Cap. Even though the 280X works OOB with Sierra, macOS stresses the GPU so much more you need a faster graphics card just to equal the performance you had before with an older GPU under El Cap.
If you take a look in Apple System Profiler and look at the PCI Cards section, does it list your link speed at 2.5 or 5.0? There's a guy selling flashed cards on eBay that has a working 5.0 ROM, and he's using it as his competitive advantage against other flashed cards. I don't care about that though, I just want the full speed link on mine:blink: Anyway, if you could post back if your EFI injection does the faster link speed, I'd appreciate it - I'll spin a new ROM for my card this weekend. I've been running a flashed 5870 in my Mac Pro for a bit now, but the one problem (other than no EFI video on boot) that I can't shake, is that it's only connecting at x8 speed (2.5GT/sec) rather than the full x16 (5.0GT/sec) that it should be, and the Apple-provided 5870 does. There's something in the ROM that tells the system that it's capable of the PCI-E 2.0 speed, that I don't have.

Ati 5870
The Radeon HD 5870 Mac Edition was a high-end graphics card by ATI, launched in June 2010. Built on the 40 nm process, and based on the Cypress graphics processor, in its Cypress XT variant, the card supports DirectX 11.2. The Cypress graphics processor is a large chip with a die area of 334 mm² and 2,154 million transistors. It features 1600 shading units, 80 texture mapping units and 32 ROPs. ATI has placed 1,024 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 850 MHz, memory is running at 1195 MHz. Being a dual-slot card, the ATI Radeon HD 5870 Mac Edition draws power from 2x 6-pin power connectors, with power draw rated at 228 W maximum.
Any ATI 5xxx series and I think even ATI 6xxxx series cards excluding the 6890/6990 will work out the box with OSX Lion. I strongly encourage you guys to not use this guide and just upgrade to Lion. Then you can use most Nvidia and ATI cards these days right out of the box on your mac without the need to flash anything.
