Please help me properly stress-test an nMP with D700 GPUs to make sure they don't need replacing.
A colleague asked me to set up a Resolve workstation for his prodco using a spare trashcan mac Pro they were repurposing. It's a 2013 MacPro, 12-core dual D700s. It's under AppleCare for about another week, so I needed to hurry up and stress-test it to see if the GPUs need replacing.
NOTE: This MacPro does not qualify for the Apple GPU recall. It was built before the recall window.
It's also worth noting that this is a replacement Mac. The owner bought one of the first available trashcans, and it had a bad motherboard. They swapped out the whole machine for this unit. It is possible that the replacement was more stringently tested than normal, as this has been Apple's policy with replacement hardware.
Okay, so this is what I did to try to provoke the dreaded green glitch in Resolve:
Source footage: BMD4KPC 4K RAW 4 clips of 5-6 minutes each, split into smaller clips for about 12 shots totalling 22 mintutes TRT.
Each of the 12 clips had the following nodes applied:
3 color correction
2 secondaries with one power window
1 blur with a power window
1 sharpen with a power window
1 secondary with a key qualifier
1 OFX with a power window
1 Resolve Temporal/Spatial NR
I turned all peripherals and let it warm up for an hour. GPU Temp around 130ºF
I rendered at Max to 4K ProRes 4444 XQ, then I rendered a second version to HD 1920 x 1080 H264. Later, I did 4K and HD H264 with render set to 100.
The internal GPU temperature got up to 156ºF.
No glitches or malformed frames that I can see.
Is there anything else that I could do to make sure these GPUs aren't faulty?
Thanks in advance for your help.
