Ohh, I think this is not so ... :(
The second PCIe x16 is only an x4 from X570 chipset. And in the manual I don't find, that I can split the 16 lines to 8/8.
So I guess I now have one of the few X570 boards where it won't work.
I just have no...
I had the change to get a cheap x570 over a forum.
So i bought a ASUS X570 TUF gaming plus Wifi.
I hope, that with this board a dual GPU passthrough will work in combination with pasthrough of an PCIe HBA.
Yes, but unfortunately, many devices of the big chipset group are accessible-from/have-access-to the Proxmox host (like the network, drive and USB controllers and more). Your VM can, in principle, read all of the host memory (and therefore all of...
I've spent several hours now looking into the ACS patch.
Initially, I had serious security concerns, but if I understand correctly, the risk depends on many factors.
If I use the patch, than the memory management group is ignored and every PCI...
It only states what speeds and lanes are available for each slot when using Vermeer or Matrisse. It does not specify that they are connected to the CPU (nor that they are in a separate IOMMU group)...
It is not possible with the 24 PCIe lanes from the AM4 socket. Where does it say that it is connected to the CPU? The website only shows which slots with which speed and lanes works when which Ryzen family is installed. It does not say how they...
Only the first PCIe x16 slot and the first M.2 slot (which is like PCIe x4) are usually connected to the CPU and can be used for PCI(e) passthrough. What makes you think the second slot will put a GPU (or other PCIe device) in a separate IOMMU...
In the manual of the ASRock B550 PG Riptide is written, that 3 PCIe are connected to the CPU.
Is this electrical possible with B550?
If yes, then I maybe give the board a try .....
It's really crazy.
The MSI B550-A Pro seems to be the only board that has two PCIe slots connected to the CPU and not End Of Life.
Unfortunately, for some reason, the MSI doesn't support ECC. :(
I'd even be happy with a second PCIe slot, even...
Make sure not to get a MSI as it blocks ECC. I believe most other brands do unofficially work with ECC but I cannot guarantee anything.
If you want to passthrough two PCIe slots (both working in x8 mode) you need a motherboard with a X570(S)...
You can find this information by checking the block diagram published in the motherboard manual or on the web.
Whether it operates with two units also requires checking the manual to see if the IOMMU can be separated.
ex...
I'm searching a B550 board with ECC support and opssibility to passthrough two PCIe slots (GPUs).
How do you find out, that the secound PCIe is connected to the CPU?
And can all boards with "AMD 2-Way-CrossFireX" passthrough 2 PCIe slots to...
Hallo,
ich betreibe auf meinem Backup Server per Passthrough einer GPU ein Windows System mit dem ich gelegentlich arbeiten muss.
Ansonsten nutze ich eher Linux mit mit der selben GPU (Passthrough).
Heißt es kann immer nur eine VM gleichzeitig...
Hello,
The console initially loads the Proxmox UEFI bootloader, but then only displays dashes when installing the TrueNAS VM.
It looks so:
How can this be fixed?
