I feel like it is 2007/2008 again .... I'm struggling with this almost whole week:
Xeon 5530 x 2
Nvidia GTX 570
SSD for OS
- Installation went smoothly, like many times before with different configurations (however this is my first dual Xeon build)
- After restart I see that I can barely interact with UI. Terrible lag and completely unresponsive. Ok .... looks like GPU issue, although that is very strange because the same GPU works W/O issues on X58A-UD3R and Z77X-UP5TH (GraphicsEnabler=yes).
- Safe mode (-x), boots fine, both CPUs are there, RAM ..... good.
- For troubleshooting I deleted GeForce.kext, reboot. System boots fine (of course with crippled graphics), but there is no lag and freezing. Definitely looks like GPU issue.
- Edited AGPM.kext (device ID and threshold), than fakesmc.kext to match Mac Pro 5.1 system definition. Installed GeForce.kext back, reboot. Result - just a bit less lag and freezing, but far, far from normal.
- Again safe boot, system boots fine, no lag.
- OK, maybe I'm going mad .... pulled out GTX 570, installed GTX 285 (also from other working system), edited AGPM.kext accordingly. Result - same lag and freezing.
- Back in with GTX 570. I installed Windows (just to check that there are no hardware issues with MB). Everything works great.
- Formated drive (to avoid temptation of the dark side )
- Reinstalled OS X with Mac Pro 3.1 definition this time (to avoid AGPM). Result - even more freezing.
- Back to Mac Pro 5.1, GraphicsEnabler=no, GPU injection via DSDT .... no luck.
- Various tests with different BIOS options,.... nothing
What ever I try, with any GPU, I always have lag and freezing. Safe boot and booting without GeForce.kext are fine. I have read countless threads trying to find solution, but W/O success.
I'm probably overlooking something obvious .... but WHAT?
Any help would be much appreciated.
