That matches my experience with the Supermicro X9DRT boards; if you don't populate the DIMMs in the expected order, the system won't post.They are quad channel.
You are supposed to populate the channels before you start populating multiple DIMMs in the same channel. Therefore if you had 4 DIMMs you would populate one DIMM per channel instead of populating two DIMMs in the first two channels.
So from your description you should populate A0, A2, B0, B2.

From personal experience, I have 4 x 16GB RDIMMs and 4 x 8GB RDIMMs in my node for a total of 96GB. According to the above, you're not supposed to mix and match capacities. I cannot mix 8GB and 16GB DIMMs in the same channel, it won't POST.
I also cannot put two 8GB DIMMs in one channel, that doesn't POST either.
So in my configuration I have:
Channel 1: single 16GB RDIMM
Channel 2: single 16GB RDIMM
Channel 3: single 8GB RDIMM
Channel 4: single 8GB RDIMM
This seems to work fine, it POSTs, all the RAM is visible. Performance is probably not optimal though since the channels do not all have equal capacities.
I can post an annotated diagram later today. CPU1 has Channel 1 starting on the opposite side to CPU0, but I don't recall which side that is. Channel 1 slot 1 is the furthest from the CPU, but the side changes depending if it's CPU0 or CPU1

Which BIOS are you running? In my BIOS I can see which channels/slots are populated.
Under Advanced -> Memory Configuration -> DIMM Information
In my BIOS there is
"Preproduction Debug Option
Show Hidden Options [Enabled]" which may be necessary to show the DIMM Information screen.
Checking now, I guess I do have both 8GB DIMMs in the same channel... so maybe it wasn't posting with them in separate channels. ¯\_(ツ)_/¯
I think the maximum performance would be at the highest memory clock. The Supermicro documentation above might have more information on memory speed with different channel configurations.
Since I have a v1 CPU I'm limited to 1333MHz.
Does anyone have a good guide on how to set up the Mellanox 10G mezzanine cards for the Wywinn's?
I have the F03C3A07 if that would be helpful.
Not sure if there is any difference of Quanta and the Wywinn 's one for the 10G card, you need to check the model of the 10G vard and download the driver and install it for the OS you are going to install .
E.g Refer this for the linux drivers for different Linuxz destro

After setting up several dozen Windmill nodes, i've grown quite weary of the all the wiring and customized rack/power issues that we had to deal with. For our new deployments, i'm looking at the Winterfell systems as a complete rack. It looks like there are two PDUs in the rack... does anybody have any information on the input power? phase? Couldn't seem to locate anything "concrete" for the 3-node Winterfell systems. I'm seeing 230, 277, 380v.. single phase, 3 phase... doesn't seem to be as standardized as the Windmill nodes.

Just remember that there's a lot about these that are nonstandard (power supply connection is probably the biggest issue to figure out). Plenty of info in this very thread.
Yes, in Russia. I was told the board weighs about 2 kg.
In fact, there are only two issues with this Board. The first is the use of a standard ATX power supply, the second is the lack of fan power connectors for cooling.
Have you tried using a normal ATX power supply with Zero Load technology? Like it is not necessary to load additionally power supply circuit 3 and 5 volt.
The PSU is a separate board when you have a dual node and there are also fan connectors on the board. This what I have.
You should look at the mod of hmartin for single board https://forums.servethehome.com/ind...-199-quanta-openrack.6856/page-34#post-175931
PS: I don't know what is the weight of a single board alone.
The firmware is brain dead. I neutralized the pwm cable to have the fans running at 100%. Hmartin made a mod to control his fan manually with a little pwm controller that you can find online for a few bucks.
My cpus are v1.

Interesting. Do you know how power is distributed from the PDUs to the PSUs? The sellers can't really provide me with clear details e.g. how much power is sent (since the PSUs themselves are the same as Windmill and are single phase) and i'm trying to figure out. The most I can get is the input plug is a 63A 5-pin commando plug. Any more PSU/PDU related pictures are appreciated..
