Hey guys,
I have a Mac Pro 4,1 updated to 5,1 with firmware. OSX 10.10.5 build 14F1912
I recently purchased the GTX 980 FTW ACX 2.0 from here.
Installed the Nvidia web driver 346.02.03f09 and Cuda driver 7.5.30
Connected the card with this 6 pin cable and this 6 pin to 8 pin cable.
At first it booted and everything was smooth and i ran a couple of benchmarks and all was well. Very soon after the 3rd or 4th boot i started getting a couple of scenarios happening:
- When i boot the card's fans go insanely fast and loud and i dont get to the login screen.
- When i boot the card acts normal but i still dont get to the login screen, stays black.
- When i boot everything goes well.
I had installed 32GB 1333 non ECC ram, Sonnet Tempo PCI card, and a 4 port USB 3.0 card as well.
I took all of those out and reverted back to my 16GB OWC ECC ram to troubleshoot and still same results.
Any idea whats happening here?
The reason i updated the firmware is because im plannng to upgrade to dual x5680 cpus but still didnt.
Cheers
