BMC information generally won't update until there's successful boot. I'd try different RAM if possible.

Previously I had ECC memory. And now I inserted the 8GB stick HMA81GU6CJR8N-VK and 8GB stick m378a1g43db0-cpb. Maybe it's a matter of clocks, but I think it should start check it.

I have a problem too. I added memory and a Ryzen 7 3800x processor. However, there is no information about postal errors. I removed the CMOS battery and replaced the memory, but there is still no image in IPMI. The processor that is detected is Ryzen 5 3600. RAM is not detected, although I took the chips from a standard PC.
Very likely incompatible memory.

I was able to update the BMC/BIOS via IPMI with only a 4650GE.

Thanks ! I assumed the .RBU also contained the BMC firmware in the same file, guess not. Updating the BMC worked, but .RBU is still not being accepted despite selecting BIOS in the dropdown.
Updating the BIOS using an OS is not option as I can't get the system to boot up with the 4650ge.

edit: Error message changed to "Failed due to update fail" which is rather cryptic

In case anyone else has this issue, I was able to update first the BMC, and then the bios via IPMI with only an APU (4650GE on hand).

Steps:

1. Update the BMC via IMPI web ui.

2. Install the CPU and a DIMM into slot A1 (without doing this you will get the "Failed due to update fail" warning)

3. Now update the bios (I used F13) and everything will work out fine.


I originally thought I was going to have to manually flash the bios, but its 1.8V and my dediprog only does 3.3V, so glad this worked.

Sorry, I struggle with PCI-E lanes :D
I'm thinking of using this motherboard as my new main proxmox host.
Is there any way of running a 10gb nic and for example 2x nvme drives in RAID1 with this motherboard?

I say yes, currently doing so. An option:
10gb NIC in the x4 slot (MCX311A here)
Then bifurcate the x16 slot for your NVME's.

Much earlier in this thread a x4x4x8 adapter is linked which works great.

Has anyone successfully passed through the SATA controller in Proxmox?

These errors and some searching are suggesting IRQ conflicts. I have been trying various fixes for a few days without any luck.

Code:
Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Transport endpoint is not connected
TASK ERROR: start failed: QEMU exited with code 1

can't derive routing for PCI INT B

SATA controller is sharing IOMMU group with USB and chipset so no, can't be done

As you mention youself, with a 4x4x8 (or 4x4x4x4) adaptor you can get some nvme running at full speed, and by doing so free up the internal slot for an sata adaptor, where the speed of lanes are less important

otherwise you need a HBA

Yes you're right that is a good option, I think I have one as well. My intention was to pass through a SATA controller to a TrueNAS VM for zfs, but if not I will utilise the proxmox cli.

I use a 4x4x8 for nvme mirror for proxmox and the 8x slot for an HBA passed through to TrueNAS, but depending on drive numbers the NVME to sata solution is better for lower power

Hey, worth it buy nowadays? i am looking for change for my SuperMicro X9SRI. for some more power, efficient and less power hungry solution.

AMD is far away from being low power. 5700X - 200W peak consumption, 5950X - 300W peak consumption (full load). Maybe some lower models.

This is not true at all... 5700x max power draw around 75w, and 5950X around 120w stock voltages ofc

Intel chips on the other hand will draw 300w at stock on cpu alone (13900K)

Idle power consumption is certainly better on AM4 than on old Xeon E5, and far more relevant for home servers than full load.
Most relevant CPUs are, or may be tuned down to 65 W TDP, and with AMD max power is strictly predicatable as 135% TDP, not 250-300% as now hapens in Intel land.
