hi there!

i recently purchased a MC12-LE0 Motherboard off of ebay. shipped all the way from germany!

anyways, the computer posts correctly, but does not boot. The BMC & BIOS firmware has been updated to 12.61.21 and F13 respectively, which are both (to my knowledge) the latest stable versions available. however, I'm having trouble booting past the loading screen for proxmox, debian, and ubuntu. proxmox is installed on an nvme drive, and both debian and ubuntu were tried both with a usb and the BMC's fancy CD image media thing. every time I would attempt to load any of these os's, they would freeze randomly, sometimes 8 seconds in, sometimes 3, sometimes even less. there doesn't appear to be any sort of meaning to where they stop booting at. out of the ~10 times i tried with the different methods, they all failed.

this is so confusing! i feel like its obvious theres some issue with the motherboard, but i dont want to discount it immediately because i paid ~$200 including youshop shipping so refunding it would only give me half the amount, as well as i'd have to go back to my old motherboard (an asus prime B550M-A, without ipmi which is why i'd like to use this one).

can anyone help me solve this? attached is a screenshot of where it froze, (booting proxmox), although i dont think it would help because as i said it's random and the point it freezes at is always different.

Specs:

CPU: AMD 5950X
RAM: 4x 128GB ECC UDIMM (HMAA4GU7AJR8N-WM)
Motherboard: MC12-LE0
Storage: 2TB Crucial P2 (CT2000P2SSD8)
Network: XG-C100C running @ 2.5G (AQtion AQC107)

i appreciate anyone who can help, and i'm happy to answer any questions

@Ruphus The 5950X supports ECC, it worked in my previous motherboard. All i did in the switch was switch motherboards.

But THIS motherboard only supports ECC ram with CPUs with PRO technologies.

@Ruphus tried it with 2x 16G non-ecc sticks (CMK16GX4M1D3000C16) and it still freezes, so I don't think it's a problem with the ECC. also if it did turn out to be the solution i'd be slightly annoyed cause for the amount I paid it had better be pro lol

realized I didn't attach a screenshot, so three are on this post, the one showing the original freeze, one showing the new memory, and one showing the new freeze. like i said it's random where it freezes so i dont think showing where it freezes will help but i've included it for clarity

this is an old picture of the freezing, with the previously mentioned 4x32g ecc dimms

new dimms & freeze

Would have been nice to have posted the info about the memory from the start.

Have a read through this tread. Numerous people appear to be having issues with this board.

That looks like an early failure in the first screenshot. SCSI driver or other storage driver issues? It's been a while since I did anything like this. Assuming that's anywhere near correct I'd try to boot some old live stick and see what driver/config it uses successfully there and compare. I'd also look for some additional logging options for more detail on the failure point.

Stepping is sometimes interesting when it fails in a different place with stepping.

@Ruphus not sure what you mean about posted from the start? i just tried it after you suggested it if that's what you mean. The

i've read through that thread already before purchasing it, most of people's issues were updating the bios/bmc firmware, or the nvme only being pcie 3x1. I haven't seen anybody with my specific issue, and there's a poster there who's used ECC with a 5950X on this board. (https://forums.servethehome.com/index.php?threads/gigabyte-mainboard-mc12-le0-re1-0-amd-b550-am4-ryzen.42579/page-16#post-420835)

@gzt it freezes with a live stick as well, tried with the ubuntu live iso and the debian installer, the ubuntu live iso freezes while the loading circle is showing, and the debian installer freezes with a blank screen (it never showed any text past selecting any of the GUI or text based installer options).

i did forget to mention, i apologize, but with the usb/iso booting, it lets me select the installer type but freezes after selecting it, i left it on the selection screen for 5 minutes and it didn't freeze whatsover, selected an option and it froze after 10-30 ish seconds, same as selecting the option immediately

Do you have an older bootstick or some other or older distribution?

@gzt I tried with arch 2024.07.01 and it also let me select an option, and froze after that.

somewhat boring! (note: the number in the top right goes up and i waited after it stopped at 159701 and the screen still didn't change, i did this for all of them)

Once again a very recent distribution. The other approach might be to look for some more logging options in the area of interest.

@gzt i really appreciate you helping but do you think you could explain how using an older distro would help really? because it worked with the previous motherboard, all i did was swap motherboards which both have the same chipset, and if it was older wouldn't it support less hardware? i'm also not sure what you mean by logging options because i cannot even get into the os, let alone enable more logging options. there's little to no logging in the bmc apart from "power down" and "bios boot completed event"

Might. Might not. Either approach might yield more information which in turn might lead to another approach.

By the way, it's a new product, you probably have some support with that. The OEM may well have an instant answer to this one if you ask them.

I made a thread in https://forums.servethehome.com/index.php?threads/gigabyte-mainboard-mc12-le0-re1-0-amd-b550-am4-ryzen.42579/, and someone suggested settings the CPU to eco mode. I tried that and it extended the time the os could run by 20-30 seconds on average, but it still ends up freezing before anything can be done. Does anyone have and guesses as to why that might be happening? and a probable fix

You’re not running XMP or PBO are you? Likely not given the use case for this type of setup but if lowering power limits to eco mode gave you a little bit of stability then something is not right with stock settings.

@SpartanVXL nope and nope! pbo & xmp are both off, I'm literally considering undervolting the CPU or swapping it with a 5800X at this point because I can't find anything online about it.
