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:

Here's my system specs:
Mac Pro 5,1 Mid-2010 dual CPU model, BootROM (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
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

    I should note, I can run Geekbench 4 Compute test perfectly fine on this same system. Here is my result:

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

    /Applications/Geekbench\ --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.

    Looks to me like there's a problem with the GB app:

    /Applications/Geekbench\ --compute metal
    Geekbench 5.1.1 Tryout :

    Geekbench 5 is in tryout mode.

    Geekbench 5 requires an active Internet connection when in tryout mode, and
    automatically uploads test results to the Geekbench Browser. Other features
    are unavailable in tryout mode.

    Buy a Geekbench 5 license to enable offline use and remove the limitations of
    tryout mode.

    If you would like to purchase Geekbench you can do so online:

    If you have already purchased Geekbench, enter your email address and license
    key from your email receipt with the following command line:

      /Applications/Geekbench -r <email
    address> <license key>

    Me too getting the same problem... it crashes on Gaussian Blur. I am using GB 5.1.0.

    I'm having the same issue on my 5,1.

    I think the common factor could be the RX580 card. I too have a 580 flashed by MacVidCards. I just installed the card today (replacing a NVIDIA GTX 780, so that I could upgrade to Mojave), and got the same hard-crashing issue you described.

    This did not occur with the GTX 780 installed.

    I uninstalled NVidia specific drivers (including CUDA), but the issue still occurs.

    for what its worth, my RX580 card was *not* flashed by MVC so I don't think flashing is related to the problem.

    this part says it all for me, that the problem is with the benchmark, not our system, not flashing, not the OS:

    That’s interesting Mel that you did not see the crash with a different GPU. I wonder if that possibly means it is a power overload shutdown from too much GPU power draw, as someone suggested. I’ve never experienced that, so I don’t know what it looks like.

    MM I’m curious does your system show the same type of black screen crash as mine? Or is that error message from some other type of crash? I don’t think I’m able to retrieve any error messages with how hard my system crashes...

    There is no other external affect on my 5,1 other than the GB test fails.
    When run in the GUI the progress window just disappears at the point of failure - every time.
    I have to use the command line that exposes the problem is with the GB 5 benchmark.

    I've used multiple cards on this system, some with greater power draws than the RX580.
    I see no evidence of power overload here. That plays nothing into what the log shows me.

    This says it all: -> Geekbench encountered an internal error and cannot continue.

    The problem is the benchmark code; only the GB folks would be able to give reliably more details.

    I can confirm I have the same issue with metal test on RX580 in HIgh Sierra.
    The test aborts after horizontal detection (there are no power issues though).

    GB4 runs the metal test fine.

    Please fix this, as I just paid for the app.

    Hi, sorry for my english (german)

    GB 5.2 crashed with Metal Test on RX 580 Pulse (flashed) but not the MP (3 times)
    GB 4.1.1 do nothing on Metal Test (High Sierra)
    I did lookup on my Hardware Monitor and possible is it the amperage A und performance Watt, explicit CPU IA-Core ? PCIe-slot and 2x 6 pin Connector are ok,
    also Power Supply. Can anybody replica ?
    Attach File 1 left GB 4.1.1 right GB 5.2 Amperage
    Attach File 2 left GB 4.1.1 right GB 5.2 Watt
    I don't know what is the limit for the CPU-Core, anyone know that?
    Also is it possible GB have a Problem.

    Latest update (5.2) still fails metal test half way through.

    Just a thought from someone whose MB5,1 where I too have a Radeon RX 580 graphics card but never had any problems UNTIL I updated one of my two monitors to a DELL P2415Q (4K capable) screen running alongside my old DELL 2407WFP (HD Screen). Running the new screen in 2560 x 1440 while the old screen is 1920 x 1200 results in system crash when playing video full screen on the new DELL!

    Running them both at 1920 x 1080 (new DELL) and 1920 x 1200 (old DELL) seems to be ok?????? Is this the dreaded power supply issue mentioned in this thread? Maybe I should unplug a few off the many USB devices I have installed...
