Try clear CMOS...

I did - i basically tried all the usual stuff, except swapping the cpu. So far, i only spot that I'm using a 5650g. QVL and latest bios shows no Cezanne support, so maybe this is an oversight by me.

I did see others in this thread say they run a 5650g just fine, soo.. Can someone confirm that they are running an actual OS on this board with a 5650g without issues?


Edit: Ignore this, the cpu was doa.

Just a heads up people, new BIOS is out F17.

1) Fixed CVE-2023-31315.
2) Fixed PKfail issue.

MC12-LE0 (rev. 1.x) | Workstation Motherboard - GIGABYTE Global

Edit:
Secure boot is back and working

Second Edit:
Eco mode is not showing for me anymore on 5950x. I had to go into PBO an set it manually. No big problem there. Would be interested to hear if everyone is seeing the same thing.
The global website does not contain F17 anymore.
I downloaded the F17 BIOS from German site and installed yesterday over BMC. It shows now as F16 and not F17. Also F16 over VGA output.

The uploader from Gigabyte probably messed up everything.

Hello
So i have a few questions about this board
I want to use a Mellanox MCX311A-XCAT CX311A ConnectX-3 EN 10GbE SFP+ NIC (which has a PCIe x8) so i have to put it on the PCIe x16 slot.
So what happens if i also want later to add a GPU?
I plan o put a 3700X CPU on it but since the PCIe slot being occupied by the NIC should a go for a 4700G CPU to use the iGPU?
I have read the thread but i saw that the iGPU is not recognized by the board because it already have one integrated?

The MCX311A-XCAT is a x4 card. Either way, putting an x8 card in an x4 slot will work just fine. you will be limited to x4 bandwidth, which on gen 3 is fine for even dual 10gbe. The physical connector for the x4 slot is open back, so any size pcie card will fit and just stick out a bit.

You can use an igpu but not for display output from the machine like you would a desktop. The board only has vga output so it would be a bad experience too. It will also (according to other posts) make remote display not work. I have not verified this though - there might be a workaround. You can use an igpu for transcoding things if you have software that supports it.

Edit: forgot to mention that the afaik, connectx3 does not support aspm and will use a bit more power idle than something slightly newer, like connectx4 or intel x710 (and some others that i don't remember at the moment). Hard to find at connectx3 prices though.

The 4x port is open-ended, so you can put your Mellanox network card there, the space behind the port is empty.

I think it will work OK, this is a SFP+ single-port, PCIe3 4x should be enough.

EDIT: @smakkerlak was quicker... And looking at pictures, I think his assession that that card is 4x seems right too.

I could have swear that it was PCIe 8x NIC.
Would i get the full speed of it or it will be limited?

I want to buy one also for my main PC and link them directly (i will be using TrueNAS)

Went ahead and tested this with a Ryzen 5 Pro 5650g, bios F18: Machine boots just fine with UEFI display and desktop available in ipmi kvm. The igpu device is available and my windows test desktop pulled the driver for it like normal.

A single PCIe 3 x4 slot has 4GB/s of bandwidth - this is 32Gb/s, way more than you need for a single 10Gb Ethernet connection.

Hello

I have a problem with passthrough HDDs to the proxmox VM, whenever I power on the VM entire proxmox freezes.

To be honest I read about IOMMU but I don't fully understand all of this.

I have 4x 8 TB SATA HDD connected to the internal controller and 1 NVMe drive as a boot device. Is buying separate SATA controller my only option? If so, what should I buy?

Additionally I have my old GTX 1080 GPU installed and I prefer to stay it there because of video transcoding. Any suggestion?

Yes you can check few pages back... But you can only passtrough all controller(In your case ALL 4 SATA drives)...

After flashing bmc firmware, it seems like some sensor related information is missing from ipmi. Everything in the log shows up as "Unknown":

Did i miss a checkbox somewhere? Can i get it back to how it was delivered?
