Questions & Answers for ATI Radeon HD 5770 Graphics Upgrade Kit for Mac Pro (Mid 2010)

It Works. I just installed one on my 2006 1.1 Mac pro. BUT: I connected each of my two 22" monitors to the mini-display ports using adapters to DVI cables, which works perfectly. Then, when I connected my HD TV to the DVI port, it won't work. I read something about it being overridden by the MiniDisplay Ports. Not sure why this happens, but Apple, if your listening, a software fix for this would be greatly appreciated! I want to use it to run my Netflix on the big 42"...

Greetings,

I have a 2008 Mac Pro 3,1 Tower with the ATI Radeon HD 5770 Graphics Upgrade Kit for Mac Pro. Currently I'm running two full HD monitors off this one card and have not had a problem.

I don't have an iMac so I can't test it out for you, but from what I've gleaned from the net, it should not be a problem.

Do a Google search for "Target Display Mode". Find the link for an article on this subject by Tom Nelson.

Indications are that all is needed for your iMac to work in Target Display Mode is a video signal at your Thunderbolt port or DisplayPort, or you can select Target Display Mode manually by using Command F2.

The ATI Radeon HD 5770 card is equipped with 2 DisplayPorts and 1 DVI port.

All you need is the proper cable. Apple now sell a shorter 50cm version.

Regardless, the ATI Radeon HD 5770 Graphics Upgrade Kit is a good buy and is compatible with all the latest and greatest software.

Cheers
Grant

Yes you can fit two but it may block one of your slower pcie slots. But there are two power connectors for two video cards on teh mother board and I know folks who are doing it. I also know it will be tricky to get the second card in once the first card is in the first slot. I have one 5770 and was using my 8800 as well but the 8800 just fried. I am going to put my older ati 2600xt in so I can run four monitors.
There however have been issues with the 5770s in general. They sometimes produce green pixels in the black parts of your desktop if you have a black picture or something with a lot of black like a widescreen movie with black bars, Some folks have them and some don't. I had some issues with my 30 inch and the dvi port of the 5770, now I have the mini display port to dual link dvi adapter and some of my issues are gone. Search the discussions there are quite a few posts on the 5770. Hope that helps.

No, this card is for MacPro towers only. There is no connector and no physical room in the iMac for a desktop card.

Hi,

You have a very similar configuration to my own machine.

The 8800GT was a good card, but often suffered from overheating, it's also quite old with GDDR3 memory; you will definitely notice a benefit with the HD 5770

Yes this card is compatible with the 2008 Mac Pro (the MacPro3,1).

I installed this card last night with no trouble. A few things to note however.

1. The card is rather large, and is designed to use all the space in the PCI Express bracket. Take care inserting it into the chassis of the machine, the power cable was a little fiddly to attach too.

NOTE: once the card was installed (I use PCIe slot 1 only one of the two screws on) the PCI bracket was fastenable.

2. The card is recognised by Mac OS X 10.6.4 (this is what Apple specifies for the card) with basic functionality, however you will need to upgrade to 10.6.5 or newer as the Mac drivers for the card are actually bundled in those newer updates.

As with any new hardware, reset your machine's PRAM once you're finished installing it.

If you use Bootcamp, there are drivers for Windows XP, Vista, and Windows 7 from the AMD website.

I hope this helps you out, enjoy your new card!

Hi Steven I have the very same setup and it works without any problems. At first I had to unplug the Mini DisplayPort to DVI Adapter after the computer started and then replug it in. After I installed Lion everything worked just fine no replugging or anything.

The answer to my own question is no.

I found a very detailed explanation in Apple Support Discussions.
