Problem with ATI 5770 and Mac Pro 2008, Problem with ATI 5770 and Mac Pro 2008

Could you tell me were to get Temperture Monitor 🙂

I am having 2 x ATI 5770 installed on my Mac Pro atm, but there isn't much point for doing so unless you need more than 3 monitors going at the same time. If you are thinking about using cross fire or that 2 x 5770 cards will make your graphic better then don't bother. It's because Mac Pro doesn't support crossfire.

The ATI 5770 card support upto 3 monitors at the same time (1 via DVI port and 2 via Mini Display Port), if your monitor does not support mini display port, you can buy adapters for the port you need, save you more money from buying another ATI 5770.

If you decide to buy another card, make sure you have another PCIe port and a spare auxilary power availabe for the 2nd 5770 card.

I don't think you can monitor temperature for the video card on Mac, but if you want to monitor other temperature, you can download the widget iStat Nano or iStat Pro, they are both free to download. I think you can monitor the GPU temperature if you install Catalyst in bootcamp windows but don't take my word on this one though.

Hi Appledine, Thanks for your reply, I wasn't so interested in running more displays as my 30 from apple has been fine. I do a lot of Video editing and when i changed to the 5770 from my 8800 i noticed a increase in performance,my programs had less lag.. they were running slow when loaded up, I was wondering if a second 5770 would help even more🙂

I doubt it would help more if you are only using one monitor, more ram might help though 😝

My Mac is running 24GB Ram and 1 x 600 GB VoliciRapter HD,and 4 other HD's the combined total 5100GB mostly used to store my Video for and after editing, there the basic's, It's funny that iMovie seems to be running heaps faster so to Motion and Final Cut X which i have been giving a go and having a rest from final cut pro, I may edit but when it comes down to computers i rely on the info that you guy's provide. I only noticed a change in performance after changing the Graphics Card to the 5770 ? Just wondering will 2 be better than 1

Ha Ha ha, Lance i don't believe you just said that you old woman😁 now back to me.. I do believe i will get the second 5770 and see how it goes, plenty of room inside a Mac Pro for another card.

Hi there! I was having a similar problem with flashing red and blue lines in dark areas and swore up and down it was the card. The card was replaced twice, and then apple took my 30" in and that was the problem! They replaced the logic board in the display, the panel, and the cable and I haven't had an issue since.

The 8800 didn't do it for me either but when I upgraded to the 57x0 that's when I started having the problem. 2600XT was fine too. I think my old Core2Duo may have done it as well but I can't remember.

I purchased the new 5770 and i'm going to put it in the other Mac Pro,later tonight. Great work Ryan🙂 i noticed that the 5770 gives a screen flicker on start up but i am not to worried about that, I wonder if the card has a problem right from the factory.

Let us know Lance if you are chasing another 30 inch Cinema HD, I do have one here in perfect condition thats only done 6 and half months work $500.🙂

I am getting little green sparkles in black areas on my mac pro while using the 30inch apple display with the ATI 5770 on the dvi port no other monitors are connected to the card, my older video card does not have the issue and is running two other monitors.

It is only occasional. I removed the 5770 and only used my Geforse 8800 xt and it does not have the issue. Is it bad vram

perhaps. I got it from a friend who upgraded his mac pro 2010 to the 5870 so it could be tough to return it.

Lance any idea if this is unique to particular combos of GPU/display.

Have you tried it with any other monitor to see if it's specific with that combination (and maybe some others) or a problem across the board ? Clearly you want to use the 30" not something else but I wonder if problems only manifest in some hardware combinations.

I don't have any Apple Cinema displays but do want to replace/upgrade the ATI HD 2600 XT in my Mac Pro 3.1.

Most user comments on UK/US Apple store seem favourable about unofficial compatibility with older MPs including the 2008 models. Having said that one user said his 1920x1200 native res Samsung was only recognised as a 1080p TV, though I can't remember what OS X version that was if stated at all. (I have a different similar res Samsung).
