Gigabyte MJ11-EC1 EPYC 3151 Mystery

[BadMax02]

EPYC Zen1 have problems with PCIe ASPM. You need to deactivate it in "/etc/kernel/cmdline" with "pcie_aspm=off". After this you need to do a "update-initramfs -u" otherwise the change will not used by the system. In UEFI the ASPM settings are unfortunately missing.

ive messed around with this a lil more after installing proxmox a few weeks ago,
for me those spamming errors went away when i turned the sata hotswapping into mode 2, others worked for me aswell but i cant recall which ones made the console spam those errors and which one didnt.

I followed the kernel parameter found here: AMD EPYC Server with Ubuntu - Enable SATA Hot-Swap - Thomas-Krenn-Wiki-en

that way u still retain the advancedpcie error reporting but dont get a spammed console, seems to be working perfectly fine for me with mode 2, but i didnt test hot swap since i dont really need it

I can't stop the board with the power button. It seems to be starting automatically once the PSU receives voltage. Probably some setting in the BMC which I didn't find ?

I've tried resetting the BMC configuration to default. Also tried flashing the F09 default BIOS I've found here, it uploads but then nothing happens (stuck at Uploaded 100% for more than 15-20min).

Provide some screenshots. What can you do? Have you tried factory resetting the BMC from the web management interface?

I have the usual BMC options from the Power Control menu. The BMC sees that the board is powered on and if I choose any of the other options (Power Off, Hard Reset, etc) and click Perform Action, nothing happens. Keeping the power on physical button pressed for about 20s does nothing.

Where can I find new bios for this MB the 126117.bin ? I tried searching for it here but no luck, bios is f09 according to the bios post screen

I can only get ram two work in the first two slots, the blue ones. anyone got quad rank to work ? I have 4x8GB reg ecc 2400 that Id like to use

Do you have a multimeter? Verify that the ATX to 4 pin adapter (the tiny black connector) has all the wires connected. There have been previous posts from people who received adapters with loose/broken connections.

It sounds like you either have:

1. Defective ATX adapter (e.g. some signal like PSU power good is spotty)
2. Defective PSU
3. Defective motherboard

I tested with 2 different PSUs (One brand new and one older). It has the same behaviour.

For the ATX adapter, I receive from PSU without the 4pin small connector connected to MB:

- Black pin -> Ground
- Red pin -> 5V
- Grey pin -> 0V
- Green pin -> 5V

When the 4pin connector is connected and power supply button is ON:

- Black pin -> Ground
- Red pin -> 5V
- Grey pin -> 5V
- Green pin -> Ground

Also tested the continuity on the adapter at both ends and looks ok.

SlimSAS-4i is already populated, you just need to cross-flash the EC0 BIOS to be able to configure it as PCIe (I believe there is also a modded EC1 BIOS mentioned previously in this thread).

In summary:
NVMe (PCIe x4, adapter required if you plan to use standard PCIe instead of M.2)
SlimSAS-4i (PCIe x4, cable and adapter required)

The SlimSAS-4i is for the additional SATA or PCIE lanes (the connector close to the SATA-ports)? If yes, do I need to cross-flash the bios to enable the PCIE lanes?

Yes, just take it from Gigabyte site: MJ11-EC0 (rev. 1.2) | Server Motherboard - GIGABYTE Global

And flash the rbu file via BMC. After that you can also unlock the other FAN headers curve controls by applying this:

EDIT: Before you do anything of that above, you should update the BMC first:

For instance, I could not dump my OG bios before the BMC update.

Thanks a lot! All seems to work fine with dumping and flashing. Now just waiting for adapter and cable.

How far have you managed to push the ram speed? I just tried 2666 (on 2400 ram). dmidecode -t memory do report higher speed but GB6 scores are not changed at all, hum. Wanna break that 1K single core score (just for fun).

Update: Yeah, 2666MHz is max. Not possible to overclock the ram as far as I can tell.

Hey fellow home server enthusiasts

I have bought a Gigabyte Mj11-EC1 previously bought at Ram König for 35 Euro and 5 Euro shipping a good deal and probably working because sold via Ram König previously but without the ATX adapter.

That is a bit of a problem because I can not find the adapter anywhere.

It seems Ram König makes the adapter for the boards they will sell but yeah this one was not so lucky to have it and they say they do not sell it separately and gave me that instruction

https://files.ram-koenig.de/information/649/power-guide_de.pdf

Well I can not solder and I have another idea so if you would be so kind and tell me that my idea is not crazy.

I can just buy an ATX 24 pin extension male to female and then cut of or rip the not needed wires off and the 4 I need insert directly to the 4 pin socket and secure with electric tape for security and never probably touch it again hopefully?
