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

i doubt he has local access.

Other Options maybe:
- Try to mount ISO/Virtual USB Image via Management Interface (GUI)
- Maybe you can change Boot Order from a Menu instead of BIOS directly, if KVM works e.g. Supermicro you can override Boot Device with F11, then select your Drive

Alternative is of course Network Boot although that depends a lot on Circumstances.

As Im understand he has access to BMC and KVM console(Video&Keyboard) so he can do everything... He can go to BIOS, edit GRUB and boot to reset password(Method 1) ...

Same as install OS over BMC(Mount ISO, boot, install) ... Im do this several times but is very slow...

all is solved, the issue was he can't send the character ^ included in the password with H5viewer of gigabyte AST2500 BMC FW.

It didn't seem so, are you sure ?

what ? solved, or can't send ^ ?

Gladly i just wasted a few settings in proxmox and just started setting it up.

 

[luckylinux]

what ? solved, or can't send ^ ?

"solved".

What he wrote there sounded more like a "I'll just reinstall Proxmox VE and start from Scratch though".

yes, and he don't use charachters in password not possible (or hard) to send in H5viewer.
but i bet the JViewer supports a Virtual Keyboard (seen with my ASRock C741)

 

[Gruenschnabel]

@Gruenschnabel what if you simply reset password?

Root Password Reset - Proxmox VE

I did ofc by h5viewer. My Keyboard isnt recognized there. I was too lazy connecting my monitor and keyboard on my server rack to do it there so i reinstalled. Took me 10 minutes.

Just installed Truenas 25.04.2.4 on that board; 32GM RAM, AMD Ryen 5 5500, latest BIOS F20 and BMC 12.61.39 is installed.

I'm getting every minutes or so this message on the console and haven't figured out, how to fix it:

1. Does everything work, and do you have something plugged into 2nd port of onboard nics ? If yes and no then why are you posting here ?

2. version 25.10 is very close to release, is your problem still present there ?

3. maybe you do 1 and 2 before posting here for a software log warning on a hardware motherboard tread ?

4. rant over

Sorry m8

bad day got the better of me !

Welcome to the forum

Normally warnings in logs can be ignored to a large extent unless it co-insides with a real hardware problem, but a lot of new users get scared for no reason at all..

Anyways your question would have been more at home at the Truenas forum than here

Bottom line it sounds like your system is running fine

 

[Gruenschnabel]

Running a Ryzen 5 5600 on the Gigabyte MC12-LE0 with a be quiet! Pure Power 12M 550W.

Any recommended BIOS/UEFI settings (eco mode, C-states, undervolting, etc.) to cut down idle power draw but still keep decent performance under load?

Idle (Proxmox with no vms/lxcs): 22-23W

Hi all

Do you know where in Europe i can buy this board? Or anyone has it for sale?

On ebay i see only boards from China.

the cheap sale is long time over. with luck you can get one for 200-250€ (scalper)

I have one board on hold for backup, but since board is very stable, I might let it go

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.

For the love of god - i can't seem to find this "1400mv" limit setting in bios. I did put it in eco mode, but it's like 2/3 speed of real 5950x.

both solutions reduce the max. current at the VRM unit.

 

[jannoke]

both solutions reduce the max. current at the VRM unit.

Was asking about the voltage limit. What "both" are we talking about. So question is is it the voltage or current or power that trips the motherboard?

I was able to tame it by setting PPT, EDC and TDC Limits. Wierd thing that it's under 2 different menus and the menus are not in sync (meaning you can disable limits under one menu and enable them on another. Would be interesting to know what happens if you set different limits under different menus.

the more voltage, the more current eats a processor. current = heat.
otp or ocp triggered.

Facinating. Not having thermal problems. Blasting MB with 3x9000RPM 80mm fans and cpu with dynatron 6000rpm blower on cpu in 20c ambient temp with zero load. If i would cool it more i would be in space. Asking about setting voltage limit of 1400mv.
