Radeon PRO V620

Hardware Hub GPU

Good afternoon all!

Looking to see if some one smarter than me can point me in a direction to get this setup working.
I just picked up a Pro V620, and am attempting to use it on an ASRock Rack E3C236D2I with an E3-1245V5, 32GB (2x16) ECC Ram, 1TB Kingston SDD.
Above 4G Encoding is enabled in BIOS ( to fix the “System is running with Insufficient PCI Resources”), but reset all other setting to default, for troubleshooting purposes.
While digging around the internet I have found AMD’s write up on it.

System Requirements (along with detailed install steps) and I appear to meet all of them.

However, I didn’t see the GPU in the rocm-smi, and got the dmesg errors below.

So, to start from square one on a fresh 24.04.2, and only an apt upgrade, in dmesg | grep -i amd, I get this

[    6.070551] [drm:amdgpu_bo_init [amdgpu]] *ERROR* Unable to set WC memtype for the aperture base
[    6.070940] [drm:amdgpu_device_ip_init [amdgpu]] *ERROR* sw_init of IP block <gmc_v10_0> failed -22

[    6.073520] amdgpu: probe of 0000:03:00.0 failed with error -22

But I see it in lspci -vnn

My guess is, this is unholy, and wont work (because it does seem a bit of a stretch with cobbled together hardware). OR, I there is a gap in my basic knowledge and have missed something.

Has anyone else been able to get this working on their setups?

What OS are you using?

Just commenting to ask but also ive had similar issues on my V520 and V540 and seems to have them working only under proxmox and Fedora for ROCM and ML tasks, but never anything else.

Apologies, I missed that!

I’ve done the AMD Quick install instructions on both Ubuntu 22.04.2 and 24.04.5.

I will try Fedora and Proxmox tonight and report back what I find.

What are your hardware specs? I’m speculating it might have something to do with my motherboard/PCIe layout.

And Fedora has the same dmesg errors… I’m going to slap it in another system all together to see if it’s a platform issue, and hopefully that is it. Otherwise its off to see about refund/warranty.

Good news everyone!

Reinstalled the Card into the original system. Forced the PCIe slot to operate at its highest speed (Gen 3). Then installed Ubuntu 24.04.2, following up with the AMD Quick Start Installation guide. Square one right? But the seller on reddit pointed me to another fellow that found updating the grub to GRUB_CMDLINE_LINUX="pci=realloc=off amdgpu.gpu_recovery=1 amdgpu.mcbp=0"

So, the card works, and shout out to the seller juddle1414 on reddit and his company Rhino Technology Group for being responsive and willing to assist.

For reference!

AMD’s quick reference guide.

P.S. If anyone wants to point me to some learning material that explains those grub changes, I would appreciate it!

Glad you got this working! Also the Video out does work on these cars by the way!

i got a pair of plyers and cut the room enough for the miniDP and it worked for me out the box on the older cards anyway

Noted! Makes me appreciate how lucky I am to be able to have the means to get hardware like this, and just abuse it LOL
