AMD Radeon Pro v540 Research Thread

[Aspect]

Going to see if i can Jank together my Radeon Pro Duo cooler to this V540, PCBs are far apart from each other but lets see if i can get something working! if not im going to be listing my V540 for sale for cheap sub $200 if anyone is interested

Any further progress?

From the looks of it, probably not. Best bet is @mczkrt and his Proxmox setup where he spoofed the ID for the VMs but he hasn't mentioned any specifics about how he got there. I know how to spoof the device ID, it's a common setting but the setup prior could be very specific.

No further progress from my side, mainly because I have setup that works for me and I don't see any reasonable way forward. I can share my notes about setting up Proxmox hypervisor, if there is any interest maybe write a short guide, but I can't promise a timeline for that.

One interesting discovery I recall - it's possible to use MorePowerTool to create working SPPT. While the card is not visible in the tool, you can export SPPT to .reg file, manually edit adapter number to point to one of V540 GPUs, and import directly to registry. I briefly tested with clock raised to 1650MHz and there was measurable performance uplift. This might interest @LabRat 891 .

That would be awesome a Tutorial and how to do it, so we can use it also

I would second any notes on setting it up in Proxmox, as it would be nice for the sake of knowledge alone.

Quick and dirty notes on installing V540 in Windows VM, running on Proxmox hypervisor.

Host platform shouldn't matter much, but needs to have decent IOMMU support. On desktop boards it's hit or miss. For display adapter, any vendor is fine, we only need it for Proxmox installation. If using discreet card, better connect it to secondary PCIe x16 slot.

Enable IOMMU in BIOS.

Proxmox installer

https://enterprise.proxmox.com/iso/proxmox-ve_8.2-2.iso

I suggest configuring static IP for host, to simplify access.

After completing installation, login to Proxmox via Web browser, click on your host in left pane, then in middle pane Updates>Repositories, disable Enterprise repo, add No-Subscription repo.

Open shell on host, run:

apt update

apt dist-upgrade

nano /etc/default/grub

edit:

GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"

nano /etc/modules

add:

vfio
vfio_iommu_type1
vfio_pci

nano /etc/modeprobe.d/pve-blacklist.conf

add:

blacklist amdgpu

update-initramfs -u -k all
reboot

Create Windows VM - detailed steps are beyond scope of this post.
Guest OS - MS Windows
Version - depending on your ISO, Pro/Enterprise version strongly recommended due to RDP support.
Graphics - Default
Machine - q35
BIOS - OVMF
Add EFI Disk
Pre-enroll keys yes
Qemu Agent yes
Add TPM yes
Disks - add OS disk to IDE or SATA bus, check Advanced > SSD Emulation yes
CPU - cores as needed, Type - host
Memory - as needed, Ballooning device no
Network - Model Intel E1000

Finish Windows setup, enable RDP, install VirtIO drivers:

https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso

Shutdown VM.

For better performance, now we can connect OS disk to VirtIO SCSI bus, and change network to VirtIO adapter.

Start VM, verify that OS boots and RDP access works. Shutdown VM.

In VM Hardware:
set display to none
add PCI device
Raw Device - look for Navi12 with lower bus-id
Primary GPU yes
Advanced
ROM-bar yes
PCI-Express yes
Vendor ID: 0x1002
Device ID: 0x7362
Sub-Vendor ID: 0x1002
Sub-Device ID: 0x1a34

Start VM, from now only access is by RDP. Manually install drivers for V540 via Device Manager. From my experience, these are most stable:

https://s3.amazonaws.com/ec2-amd-windows-drivers/latest/22.10.01.12-220930a-384126e-WHQLCert_.zip

If you need virtual display for streaming, use these drivers:

For good gaming performance, I recommend Sunshine/Moonlight combo. Other streaming apps should also be fine. GPU hardware encoding is working.

Much appreciated for your notes, I think I can replicate this another day but I am unfortunately not able to for quite some time.
