Has anyone found a workaround for the red screen glitches using an AMD Radeon HD 7950 on a Mac Pro 3,1?
Is the only solution to install an Nvidia GTX 680? Is that the best Nvidia card you can put in one of these old beasts and resolve the graphic glitches?
TIA
+1 for that request, I'm late to the party on this thread, I have a Mac Pro 3,1 I've been using the Sierra dosdude build for a few years, but now I have to move up to High Sierra for Logic 10.4.5. My asus card has a flashing glitchiness. I installed a 5770 last night and still the glitchiness, not a red screen however. I've ran the patch again, no luck. Still glitching, flashing, rolling horizontal lines that move from bottom to top vertically, screen redraws every few seconds on Logic mixer view etc, open up a plugin GUI and it's black inside, not GUI. I'm gonna try the 2.3.2 High Sierra patch I read about in some thread #1700 ish. If that fails I have a seller lined up for a Nvidia GXT 285 , for $50 that'll be the next step for me. Is the 680 the best case scenario I'm asking myself too .
Update: I bought the GTX 285 ; $40 , failed to realize it takes two PCI-E apple 6 pin molex power cables, sourced another from a friend and I'm back in business. Ran that script that uninstalled the amd gpu patch and all seems good now, I'm running the GTX 285 alongside the original Radeon card that came with my Mac Pro 3,1 running 3 or 4 monitors at the moment, seems pretty good. I do get the occasional audio drop out when first playing audio from a stream, itunes or logic , but it's rare and doesn't affect me too negatively, mostly doing work in Logic and happy to be running 10.4.5 the latest version atm on a machine that's coming up on 12 years old , it's older than my youngest child and I'm a Grandparent .
