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

I am returning from Bulgaria tomorrow and will get back to messing with my setup. It's not a major problem just a bit of a nuisance. Usually if I unplug the 30 inch dvi connection to the port on the mac pro while its on then plug it back in, it then fixes the issue at least for a while.. It happens very randomly and usually after the computers been on for a bunch of hours.

Musicfromcapalaba.... That's a very generous offer thanks!, I will see what switching around the monitors does as Pro Tools does not need much video card power and the 8800 will be fine to run my 30 inch while I work.

The 5770 on the whole is good and I have no resolution setting problems at least with the 30 inch, I will post what happens when I switch around the monitors, thanks all.

Great Jazzimus!!

Please do as I could get my friend who I bought it from to return it for me.

I have an issue with Pro Tools and the new mbox pro and Avid said it could be the video cards are sucking power away from the firewire ports, Does any one know if this could be true?

I'm going to switch the montors around and hook my 30 inch to the 8800 and my acer then connect my 20 inch to the 5770 and see if the pixel issue shows up on it. It most likely will take a few days to see if it shows up or not because it does not always happen.

It seems the issue only happens with the 30 inch monitor which is a duel link dvi connection when connected to the dvi port of the 5770. My other monitior does not share the issue. I hooked up my 22 inch older apple display only to the 5770 and have not seen any green pixels in over a week and the desktop photo has a ton of black in it where the issue usually occurs. My thirty inch is connected to the geforse 8800 and there have been no green pixels there either so it apperars to be an issue only when the 30 inch is connected to the ATI 5770. So not sure what to do at this point I guess I can try to return the card but I bought it from a friend who got it with a new mac pro then and he then upgraded to a 5870 it would still fall under his one year waranty.

Don't really want to spend the money on a duel link mini display port to dvi adapter to see if the problem still persists. hmmmm what to do.

Cool, keep me posted, I just updated to 10.6.8 and switched the monitors back, 30 inch on ati 22 on geforce, will see if it appears again.

Well my Geforce 8800 just died and my 5770 is really acting up and I have boot problems when it's attached to my 30 inch so not sure what to do at this point, I think my 30 inch is slowly dieing. Apple does not support the 5770 with anything older than a 2010 mac pro. I saw on youtube that people are baking their 8800 in the oven to fix broken solder connections which is really odd but it seems to work so seeing its dead I will try that.

I may buy a dual link dvi to mini display port to see if that works with the 30inch better than when connected to the dvi. Is anyone using a dula link minidisplay to dvi adapter with their 30 inch and is it working? I guess it's worth a shot as I can return it in 30 days. Oddly my green pixel issues seems to be gone and only happened when I connected the thiry inch to the 5770 not with smaller monitors. Lately I've been using my 8800 with the 30 inch and a 22 inch, and my 5770 is connected to a 720p tv. All was great but not really how I want my setup as I bought the card to run my 30 inch, Then yesterday at the end of my session working on a film score I got jaggies across both screens via the 8800 and then they went black for good, the card died. Dang it!

I bought a mini displayport to duel link dvi adatper from the apple store to see if it would fix some issues I have been having with my mac pro and the 5770. The green pixels had stopped on the dvi port lately for some reason but now it's back using the adapter. What is gone however is the errors I was getting in Pro Tools 9 using an Mbox pro 3. I kept getting error 6085 and now that Im using the adapter I am not at least so far. I only get green stuff in the black areas as described before. I will try and get my card replaced if I can, but I bought it from a friend so it will be a hassle and my local apple store was not even showing the 5770 in their list of video card options just the 5870. That was odd. But I am happy I can work without errors and the reason I believe is the adapter sends more power to the 30 inch monitor via the minidisplay port duel link dvi adapter than connecting diretly in to the dvi port. This should not be the case but whatever is going on the adapter seems to help my main issue with Pro Tools, minus the green pixels when the screen has a lot of black that is there now and disapeared for quite a while when I was connected to the dvi port. Strange stuff.

No not going to do any baking except for outmeal cookies😁 8800 card is dead put older 1600xt in with the 5770 and the mini display port to duel link dvi has fixed my issues with not enough power going to the 30 inch monitor, I guess the active part of the adapter is helping the 30inch is helping. Now have 4 monitors running, keep my fingures crossed. I think the 5770 does have issues with duel link connections.

Jazzimus is your replacement still working without issues?

Apple replaced my card but the issue is still there and if anything it's worse than it was before guess I should have kept my card and returned the new one. It's only with my thirty inch display though. I guess I give up and will live with it until the new Mac pros come out.
