Have you tried this exact one? I need something just like this one.

Yes, I've been running this card for a couple of months now, with no issues.
just recently installed 2 Optane P1600x in the nvme slots for meta device in Truenas, no problems

There are many sellers of this exact model, just find the cheapest listing on the day

Interesting, how strudy is the thing with a low-profile card as there's no support at the bottom?

I believe if to use it with low profile x8 pcie, but with standar support which in the end to the mb would be fixed to the case and other end fixes on screw. so it would makes sturdy line from pcie slot to the end of low profile pciecard. And the whole Decepticon thing should be pretty solid overall)

Uhm....I like your logic but sadly if you use the standard profile bracket the screwholes are in the wrong end. :(

If you use a low-profile bracket on the x8 PCI-E. it will be the height of a normal bracket when mounted in adaptor and screws right in any normal size case

Looks a bit bodge granted hehe, but quite sturdy and is not going anywhere :)

Have not used that specific card yet, but ive used similar size x4 to x16 etc just physical adapters and never had any concern.
Since it has a screw hole + i dont think i have low bracket for the nics anyhow il probably just 3d print a new full height with adapter+nic screw holes.

Plus on a sad note i suppose, the supply of cards is going doooown.

For anyone interested in this board but not thrilled with the shipping options, its priced quite aggressively priced on Amazon DE. €53 + €30 shipping to New Zealand as an example.

Has anyone seen good deals on 32gb ECC udimms? :)

No such thing. I've literally found it cheaper to wait for crucial to have site sales and just buying micron udimms.

Beware :

The Kingston Server Premier KSM32ED8/32HC, only works with 2 sticks not 4 on this board, properly due to the dual rank nature of the sticks

funny enough my ASRockRack X470DU4 based on the older x470 chipset boots fine with 4 sticks

Can you be more specific about the problem with running 4 sticks of KSM32ED8/32HC on this board?

I'm using MC12-LE0 board with 5900X CPU and 4x KSM32ED8/32HC, and it seems to work correctly:
Code: 
# dmidecode -t memory | grep 'Part Number\|GB'
        Maximum Capacity: 128 GB
        Size: 32 GB
        Part Number: 9965745-039.A00G

        Part Number: 9965745-039.A00G

Was the observed behavior "does not boot" or "runs with stability issues"?
Thanks!

The only minor "issue" with this board:
Front USB ports are handled by a controller in a large IOMMU group, unsuitable for passing to VM.
Passing individual USB devices works.

(GPU and back USB ports controller can be passed directly to VM as PCIE devices.)

Thank you !

That's somewhat good news for me then :)

I haven't been able to get post with 4 sticks. 2 sticks posts right away (5600x)

Could you share some memory settings and bios version ?

Do not remember changing any memory settings.
Just installed the CPU, memory and it booted and detected all the memory, so it should work with default values.
Later updated BMC and BIOS through BMC web interface, and verified the machine using complete memtest run.

Well.. changing CPU to my 5700x worked ... board now boots fine with all 4 dimms :p 128GB FTW lol

my 5600x is from one of the first batches bought very early on .. something happend with mem controller for the better with later on sku's and batches...

actually good job AMD :)
