I'm just curious if anyone can share any experience about external PCIe devices (particularly GPU) over SFF-8654? My Asrock Rack ROMED8 2-T only has full x16 slots and many GPUs such as the Intel ARC B50 are electrical x8. In addition, a duo card frees up 2 slots, effectively losing 32 lanes...

Hi all, I used AI to summarize what I have tried, the problem, etc... Problem Statement Issue: NVIDIA RTX 5090 GPU negotiates PCIe x16 on cold boot but downgrades to x8 after Function Level Reset (FLR) during VFIO passthrough to a VM. The ASUS X870E motherboard's PCIe controller incorrectly...

Hello all, I've followed the PocoLoco guide to get the vGPU drivers installed on one of my Proxmox servers, but I'm having a hell of a time getting any VM to start with a mediated device selected. Every so often one will boot, but mostly I'm getting the same error across multiple Windows and...

Hallo zusammen, bin schon länger aus dem Hardwaredschungel raus und wäre dankbar über Einschätzungen, Beratung und Tips. Ich plane evtl. meinen Server zu ersetzen. Dazu erstmal derzeitige Randdaten und Nutzungsverhalten: Fujitsu Primergy TX2450 M1: Genutzte Software: Nun ist mein...

Hello, first time on the forum so sorry if I do something wrong. My problem is that after updating my server from version 8 to 9 I started having problems with my TrueNAS VM. The configuration is pretty simple, I just have one of the SATA controller on my board passthrough to the VM. Basically...

I keep getting the error on only *some* of my nodes when trying to edit the PCIe resource setting on a VM that 'Parameter verification failed (400)'. I have resource mapping set up across all nodes that have GPUs (Tesla P4s), they are all the same GPU and since they're on the same slot on the...

Hello, I've had PCIe passthrough working for quite some time on a TRX50 Threadripper build with an Nvidia 4070ti Super Asus Tuf and an AMD 7900xtx Sapphire Pulse. I recently swapped the 4070ti Super out for an AMD 7700xt Sapphire Pulse, though, and started having issues. On two different...

Hello, I am struggling to get audio passthrough working well on one of my Proxmox machines. I have tried USB and PCIe passthrough and in either case I get minor crackles on occasion, but it's a bit better when using PCIe passthrough although still not acceptable to me. I believe the devices...

Hello, I use proxmox with kernel: # uname -r 6.8.12-2-pve I have ASUS Radeon RX 7900 XTX TUF Gaming OC 24GB GDDR6 installed in PCI slot From proxmox I can see it as: 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX] (rev c8)...

I am trying this ASROCK X470D4U + CPU 3700X combo and to make a proxmox based hyperconverged server. As the title said, whenever I enable sata ahci or nvme controllers in PVE (both amd and asmedia), the machine would crash. i.e. symptom: immediately blank terminal screen in live tty session...

Should I sell the RAID controllers in each of my R740s and just put Mini H330 HBA controllers in? The general consensus seems to be to use ZFS, so why waste a PCIe slot on these things?

I'm running Proxmox 8.2.2 with a GPU passed through to a VM. When it's booting, the image on my screen freezes right after Proxmox boots - so I can't really do anything on it, but the VM passthrough works well. Now, I've tried to insert a new PCI-E Wifi/BT card. Proxmox then boots up, but gets...

Hi there, I have the ASUS XG-C100C in my PVE host, but since the latest round of updates it get the following error message: Apr 16 09:38:00 pve1 kernel: e1000e 0000:00:1f.6 enp0s31f6: Detected Hardware Unit Hang: TDH <cd> TDT <4> next_to_use <4>...

I've installed a PCIE NIC into my machine running Proxmox, but no new interfaces are showing up under the network tab. I can tell that the NIC is detected by the computer because it shows up when I run lspci | egrep -i --color 'network|ethernet', which I've shown in the first screenshot. The NIC...

Hello, after my proxmox node started having really bad performance issues in my vms, I decided to reboot the node and after reboot, networking refuses to work and the network card reports "PCIe link lost, device now detatched", and most if not all of my pcie devices fill my screen with the...

I have been trying for hours to get the Coral TPU (install in a pcie slot) operating correctly in Proxmox. I'm on the lastest dev 6.5.11-7. I've followed the instructions on the Coral website (and tried many workarounds from google searches!) and am at a loss. Coral TPU is recognised...

I am trying to add a 2.5" SSD to my system using the Accelsior S PCIe adapter card. When I add the card to the system and boot, I can see the disk drive in fdisk as well as format, add/remove partitions etc. But then my ethernet connection is broken: Jan 13 14:26:08 pve-1 networking[887]...

I have a asus Z9PE-D8-WS which I recently installed a Asus hyper m.2 into to get myself some high speed(ish) storage. Problem I'm having is Proxmox only detects the first drive out of 4. As far as I can tell, PCI-E bifurcation is enabled and set up as 4x4x4x4 on the required slot, The bios...

Hello everyone, I hope someone can give me some clarity about PCIe Lanes. Situation with a Mellanox X3 10GB network card. I have a PCIe 4.0x8 slot working on 4 lanes (CPU lanes) The duo Mellanox card uses a 3.0x8 connection. As far as I know 10 Gbps lets you transfer at a rate of 1.25 GB/s...

I'm trying to passthrough 2 GPUs to the same VM without luck. If I boot it with only one of them configured, the VM boots and everything works as expected. But when I configure both at the same time, the VM doesn't output anything nor collects logs (checked multiple logs inside `/var/log` and...
