RTX PRO 5000 Blackwell 72GB: MIG cannot be enabled / "Not Supported", but 48GB works fine on the same system

Body:

I’m trying to enable MIG on an RTX PRO 5000 Blackwell 72GB card, but I’m getting Not Supported. The puzzling part is that the exact same steps work perfectly on a 48GB card in the same system.

My setup:

  • OS: Ubuntu 26.04 Server

  • Driver: 595.58.03 (Data Center Driver)

  • Tool: displaymodeselector 1.72.0

72GB Card (the problematic one):

  • vBIOS: 98.02.9F.00.01

  • SKU: G153-0540-0

  • Build Date: 11/21/25

  • MIG M. in nvidia-smi: N/A

Steps I followed (from NVIDIA MIG User Guide):

  1. sudo systemctl isolate multi-user.target

  2. sudo rmmod nvidia_uvm nvidia_drm nvidia_modeset nvidia

  3. sudo ./displaymodeselector --gpumode

    • Selected option 1 (physical_display_disabled)

    • Result: Specified GPU mode not supported on this device 0x2BB3

Comparison (48GB Card - working):

  • vBIOS: 98.02.92.00.01 / SKU: G153-0530-0 / Build Date: 09/18/25

  • Same steps: ✅ SUCCESSFUL

  • MIG M. status: N/A → Disabled → Can be enabled

My questions:

  1. According to official NVIDIA MIG docs and tech reviews (TechRadar, etc.), the RTX PRO 5000 Blackwell should support up to 2 MIG instances. Why is the 72GB SKU failing?

  2. Could this be a vBIOS compatibility issue with displaymodeselector? The 72GB card has a newer vBIOS (9F vs 92).

  3. Is there any vBIOS update available for the 72GB SKU (G153-0540-0) to fix this?

  4. Do I need a separate license (like NVIDIA AI Enterprise) to enable this on a single 72GB card?

I’ve attached the logs and comparison table. Any help is appreciated.

Hi @shutong8511,

This topic is about Aftermath SDK, but not MIG. Maybe you need to ask in the corresponding topic.

Thanks

Finally, the new version of displaymodeselector tool v1.76, which supports the 72GB version of RTX PRO 5000 is released:

Pls. use this version of the tool specially for the RTX PRO 5000 variant with the 72GB of memory, this GPU is only supported from this version onwards…
Change the RTX PRO into display=OFF, to then be able to enable MIG…

Appologies for the delay..
