EU Gigabyte Mainboard MC12-LE0 Re1.0 AMD B550 AM4 Ryzen

[Cruzader]

4 of these boards with 5700x and a set of these will be my compute now, probably under that 400w for the 8 of them idle.

i bought one of these boards and had it shipped to new zealand, and it appears to not be working? it posts, but booting into proxmox/debian/ubuntu/arch fails, with it freezing 10-30 seconds in (proxmox being off the m.2 and the others both with a usb and the iso option in remote control). if there's an installer screen, it appears to be able to idle there indefinitely, but it will freeze again 10-30 seconds after selecting an option. has this happened to anyone else? is the board DOA?

cpu is a 5950x and i tried with both ecc udimms (HMAA4GU7AJR8N-WM) and regular off the shelf stuff (CMK16GX4M1D3000C16), had no effect.

everything worked correctly before, this issue only started happening after swapping my motherboard from an asus prime B550M-A to this one.

bmc updated to 12.61.21 & bios to F13.

Same for me and some others in the German forum. Seems to affect only 5950X. Worked for me after going to BIOS and setting "ECO mode" (can't recall the exact naming convention, might be "turbo-boost: off" or the like). The hypothesis is that for the 2-CCD chips the VRMs are underpowered causing power instability and crash when the CPU boosts.

CPU is in QVL - should not be a problem.

Agreed, it should not be a problem, but it is. Also it's a reproducible error with several reported cases and there is a workaround.

check IPMI LOGs for temp issues.

 

[msth]

I checked and there were no errors. Also measured the temperature of my VRMs and they were cool.
But yes, there are reported cases for this board where the VRMs overheat. It was recommended to use high airflow coolers and/or top-down blowers.

 

[Joyte]

i disabled quite a few settings:

• set it to eco mode
• disabled precision boost overdrive
• some other setting called core performance boost, under AMD CBS -> CPU Common Options

and it works! kind of. it went for a total of 100~ seconds before failing, i was able to log in and run commands before it froze with three final messages: [sr0] CDROM not ready. Make sure there is a disc in the drive. repeated three times.

My assumption is, based on what you said, that the vrms are slowly getting hotter instead of suddenly getting super hot? that's my guess anyway, do you or anyone else have any other ideas?

 

[Joyte]

check IPMI LOGs for temp issues.

no temp issues in logs. also it seems i spoke too soon because the ~100s was just a lucky shot, it seems to average around 40s with a couple times going high

attached is an image of the sensors: it froze around 30 seconds in, so it should be visible.
the fans are set that high on purpose

shows "Normal" sensors LOL
have you a Temp Gun ir IR cam to view the VRMs ?

 

[RolloZ170]

Also measured the temperature of my VRMs and they were cool.

how ?

 

[Joyte]

i'm still having the same issue, with the freezing just delayed a bit. does anyone know a potential fix? would swapping to a 5800X i have on hand help at all?

Hi everyone,

Can someone write tutorial/guide what options in BIOS will increase power savings(System use less power)? BIOS have a lot of options and probably some of them do not imact performance to much but can save some energy...
For example id disabling serial console safe some power?
Or for example disabling SRV-IO?
Disabling onboard LAN card will save some power(I need only IPMI + 1x LAN) so another one will not be used?

About bifurcation with 8x + 4x nvme + 4x nvme aliexpress adapter which setting need to be set in BIOS? 8x4x4x or 4x4x8 ? Im asking this because this ali express board will arrive probably in the middle of august but I have one spare ASROCK HYPER QUAD M.2 PCIe board and would like use 2x nvme and prepare and test system and later only replace card... Im not sure if moving nvme to another pcie lanes will produce some issues but still would like minimize this option...

Try to use powertop --auto-tune now if it will bork your system just disable anything you do not need such as sata hotwap

 

[_Dejan_]

I know for powertop. In current system it didn't make any difference. Only changing from performance governor to power_safe make difference 248W -> 241W for whole rack(Around 190-200W is server power consumption)...

All parts for "new" server are ordered and I think I will have them next week...
Conf:
MB: Gigabyte MC12
CPU: AMD Ryzen 5 5600
RAM: 2x Kingston KSM32ED8/32HC
SSD: 2x NVME Seagate Nytro 5000 960GB

Case: INTER-TECH IPC 4U-40240
PSU: BE QUIET! Pure Power 11 500W 80Plus Gold (BN293)

Around 190-200W is server power consumption)

That does seem very high. My main Truenas build with this board uses 138w from wall at idle and that includes separate router (n100) and switches (CRS309-1G-8S+ and cheap 4+2 realtek)

Truenas consisted of 5700x, 128gb ECC, 8 HDDs, 4 SSDs, 3 NVME, LSI controller and a X710-DA4 NIC

sorry I misread, this is your old system ofc

New build should use less

 

[_Dejan_]

Yes this is power consumption of my current server which is Supermicro H11DSi motherboard, Epyc 7601 CPU, 128GB RDIMM RAM(8x16GB), Mellanox CX354(Using only 1x10G), 2x Samsung PM983 960GB, 2x 8TB HDD, few FAN's ...

Hi all,
I found a fix for my issue. It appears to be related to the 5950X only. I limited the core voltage to 1400mv, and the crashes stopped. This is apparently a common issue with the 5950X, happening ~2 years after purchase (coincidentally, it's been 2 years and 3 months since i bought mine).

After limiting, all crashes stopped, and booting into the operating system worked flawlessly.
Thanks to everyone who helped.

Im receive parts and update BIOS & BMC and install proxmox.
With BMC and one LAN connected idle power usage is 42W(Running only proxmox)

System:
MB: Gigabyte MC12
CPU: AMD Ryzen 5600
RAM: 2x32GB Kingston KSM32ED8/32HC
NVME: 2x 960GB Seagate Nitro 5000
LAN: 1x TRENDnet TEG-10GECSFP (DAC Cable unpluged)
PSU: BE QUIET Pure Power 11 500W 80Plus Gold (BN293)

Is there some way to decrease power usage little more?
