Geekbench 5 Compute test crashes RX580 Mac Pro 2010

I've just tried running Geekbench 5 Compute test twice, both times the system crashed in a drastic way I've never experienced before. When the Geekbench 5 app is the only app open, suddenly the screen goes black and all the system fans start running at full speed. The caps lock key on the keyboard still toggles on and off but I can't use the system, have to hold the power button to turn it off. This happened the first time while the Geekbench app was open to the Compute tab but not running the benchmark, I believe. Or maybe I had just clicked the button. The second crash happened about 15-30 seconds into running the Compute test.

I was able to run the CPU test without problems. Here is my result: https://browser.geekbench.com/v5/cpu/141029

Here's my system specs:
Mac Pro 5,1 Mid-2010 dual CPU model, BootROM 144.0.0.0.0 (latest)
MacOS Mojave 10.14.6 with all updates
Dual 3.33GHz Xeon X5680 processors (upgraded)
Sapphire Pulse Radeon RX580 8GB with Apple EFI from MacVidCards.com
48GB ECC DDR3-10600 RAM (3x16GB matched set)
Sabrent Rocket 1TB NVMe SSD in IO-Crest SI-PEX40129 dual NVMe PCIe adapter
Inateck KT4001 USB 3.0 PCIe adapter
WD Red 6TB x2 RAID 0 + WD Green 2TB concatenated (JBOD) Apple RAID array
LG 3840x2160 Monitor (DisplayPort) + LG 1920x1080 Monitor (HDMI)

    I should note, I can run Geekbench 4 Compute test perfectly fine on this same system. Here is my result: https://browser.geekbench.com/v4/compute/4538080

    Could you run the following command from the Terminal and send me the output?

    /Applications/Geekbench\ 5.app/Contents/Resources/geekbench_x86_64 --compute

    Hi John, that caused my computer to crash hard again, in the same way.
    Which, I wish you would have warned me about, because I was in the middle
    of an important work file upload.

    I believe it crashed after it said it started the second test, "Running
    Canny" or something like that.

    If there's a way I can send you diagnostic info without running the test /
    crashing my computer, I will, but I don't want to suffer another crash like
    this again, it's extremely concerning.

    PS, running this command made me notice the Geekbench 5 app is in my
    Downloads folder, not Applications, if that makes any difference.

    Interesting. I have the almost exact same config as you and I ran the GPU benchmark. I got a crash during the compute phase (Gaussian blur) - computer actually shut down. I had to power cycle the Mac to turn it back on again. I read somewhere else that maybe the power supply isn't sufficient for these updated tests for Geekbench 5.

    Hi there, thanks for following up about this.

    I have heard of Mac Pros crashing due to overloaded power supplies from GPUs drawing too much power. However I have never experienced that on my Mac Pro with this GPU even when running known power-hungry benchmark / stress-test apps like Furmark.

    I guess one way to test that would be to run it with a GPU that draws less power than the RX580.

    My cMP5,1 shuts down in the middle of the GB test. My video card is installed in an expansion chassis with its own platinum 1500W PSU so the power draw inside the cMP should be minimal.

    Again, I've said that before and I'll repeat it: if your OS crashes while running a user space application, it's the OS issue, not the application's.

    Please consult with "How to Use the Mac Console App to Diagnose a Crash" (find it via Google - this forum doesn't allow me to post links).

    Then google for Technical Note TN2118, Kernel Core Dumps.

    In any case you should request support from Apple, not from GB.
