Body:

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

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 (physical_display_disabled)1

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

Comparison (48GB Card - working):

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

  • Same steps: ✅ SUCCESSFUL

  • MIG M. status: → -> Can be enabledN/ADisabled

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 ( vs ).9F92

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

  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.

Hey there, we’re having the exact same problem with an RTX Pro 5000 72GB, the identical vBIOS Version and the 1.72.0 Version of the Displaymodeselector.

Any help would be highly appreciated. We’re stuck with an unusable GPU for our setup for weeks.

Thanks!

Apologies to both of you, it seems to need the v1.75 of DisplayModeSelector tool to support the 72GB version of RTX PRO 5000, to change that one to display=OFF mode, and then enable MIG…

I’ve been pushing internally for the website to offer that newer version, pls stay tuned, I’m increasing urgency and frequency of my requests to the owner of the tool/website…

thanks

Thank you very much. Please send the operation method and download link when DisplayModeSelect version 1.75 is released. Thanks!

Hey, did you get an updated Displaymodeselector-Tool or how did you achieve that? Thanks!

DisplayModeSelector 1.75

Where did you get that Version from? NVIDIA Display Mode Selector Tool | NVIDIA Developer still gives me the 1.72 Tool.

I’m also checking, and still get pointed to public v 1.72.
It needs v1.75 at least, to support the newer SKU with 72GB. We are working on updating the webpage with v1.76, as we speak, but there are a few more edits (around defaulting to MCDM instead of TCC starting with r595 driver), and updating the docu takes some extra steps and time…
I shall update here, once I get green light, a newer version - one that supports the 72GB version - is online…

thanks for your patience
