Replaced the battery, still nothing.



No, I don't have any graphics card installed.

So the last few days have been a bit chaotic...
I manage to get another PC to test the Ryzen 5 4650G, and it got to the BIOS in a B450 Tomahawk Max.
Also I tried again in my MC12-LE0 motherboard with the Ryzen 5 3600 but now with my RAM and I was able to POST and get to the BIOS.

So I'm not sure what to do :( I think I will give up on the 4650G and buy a 3600, what do you guys think or have any CPU suggestion?
Did I forgot to test anything?

Thanks.

I don't think that problem is in battery... Also BMC version do not effect board boot...

I had 3 boards, 3 CPU's and 3 memory's and run them in this configuration without issue:
1.) MB + CPU 5600 + 64GB(2x32GB) NON ECC RAM
2.) MB + CPU 5600 + 64GB(2x32GB) ECC RAM
3.) MB + CPU PRO 4650G + 8GB(1x8GB) NON ECC RAM

System with PRO 4650G CPU boot normaly with stock BIOS and F18...

I run mine off a 5600 from Ali Express. I think it cost £60 :) Happy with it.

Got a 5900X running on one of these boards I have. I finally found Eco-Mode for this version of the BIOS (ver. F18) but was wondering if anyone saw any impact of the "cTDP" option set to manual.
Setting a value (example 65W) doesn't seem to do anything. Has anyone gotten this to work by chance?

Edit: After some more digging around, I found this German forum that has a lot of useful info too around this MB:

[Sammelthread] - Gigabyte MC12-LE0 (AM4, B550, servertauglich: IPMI, Dual Lan, ECC)

2 New BIOS releases in the last few days. I assume F20 is a bug fix for F19 but no release notes.

Edit: from relase notes in F20:
F20
1. Fixed Gigabyte Logo display.
---------------------------------------------------------------------------------------------------------------------
F19
1. Update AGESA 1.2.0.E.
2. [Security Update] CVE-2024-0179, CVE-2024-21925, CVE-2024-36347.

My av went mental when I unzipped F20, did you have any issues?
