I am planning on finally rebuilding my NAS this winter after plenty of time tinkering! Bought back in 2024! Glad I got my 64GB DDR4 EEC when I did. Thought it was expensive then 
There was a new SOP manual added to the support page a few days ago for doing BIOS updates. New BIOS soon I hope!

Isn't F20 new even though it's dated april 24 ?
I just updated to 3 boards to f19 the other day and don't remember seeing f20 at that time
Hmm I am not too sure. I think f20 came out a day after f19 after some really basic mistake. I will download and check the notes. 2min
Nice 1am planning on finally rebuilding my NAS this winter after plenty of time tinkering! Bought back in 2024! Glad I got my 64GB DDR4 EEC when I did. Thought it was expensive then
Ya same here got 4x32 and 4x16 spread over my 3 board, most expensive ram I ever bought at the time, but nothing compared to now
I am using 128GB DDR4 non ECC in my second one (still testing over a year later also...more of a time thing really)
Would be nice to run that at XMP.
Anyone know if any of these secret BIOS options let you set RAM voltage manually? That seems like the biggest hurdle.
Its all good at 2133 but I’d like to try and get it at the RAM’s rated speed (3200) just for fun.

Sorry never had the need to, all my 3200MT's are detected and run at 3200 OOB
Your ram has to have JEDEC spec set to 3200 as base and not via XMPYour living the dream there
Most RAM only has 1333 in JEDEC spec + XMP profile
From Kingston PDF : The SPD is programmed to JEDEC standard latency DDR4-3200 timing of 22-22-22 at 1.2V
If anyone ever comes across this:
I worked around this by moving the GPU from the x4 slot of the board to the top x16 slot which would probably be the one expected to run GPUs.
It works in this configuration although I think it should've been doable with the other slot as well.
Any BIOS Settings that are recommend for using an Intel Arc A310 ECO 4 GB for jellyfin transcoding and low power?
I just enabled aspm in TrueNAS, I don't think there was anything to set in the BIOS
Hi guys,
I've been using the MC12 for a couple of years. In December 2025, I managed to buy a couple of DDR5 32GB ECC UDIMM RAM sticks, and since they're just sitting around, I decided to try building an AM5 platform with the follow-up model, the MC13.
I found a refubrished board with a one-year warranty on eBay in Germany, but it appears to be defective. The BMC works well, but there is no POST, and it shows devices in the WebUI that I did not install (CPU, RAM, and SSD). Therefore, I am going to return it.
Interestingly, the MC13 only supports the Ryzen 7^(th) and 9^(th) series, as well as the AM5 Epic. However, it doesn't work with the 8^(th) series APUs at all. They are also not in the QVL. Therefore, I will stick with my plan for the future upgrade: Ryzen 7 Pro 8700GE, Asrock B850, and PicoKVM.

This list is only populated after a successful POST, so it's probably the components installed prior to the board being removed from service.
I very much hope you did not pay 700€ for this
The price tag was €360, shipping included. I used the CPU and RAM from the QVL, and they worked very well on an Asrock board.
In general, I find that these new MC13 boards are very limited in terms of PCIe, M.2, and SATA slots. This makes them difficult to use for a home server.
In this case, I would probably be better off getting the MC13-LE3 model (which saves one PCIe slot for SFP), but it costs even more than the LE1 model. Therefore, I will choose a consumer board with ECC support (MSI is out).
