X10SDV-8C-TLN4F+ build questions

[cinfd]

I'm planning a compact low power server to host multiple linuxVMs, Firewall & VPN. Redundancy/backup is not an issue. Current plan is:
Operating System/ Storage Platform: HyperV Server or linux kvm/qemu
Motherboard: Supermicro X10SDV-8C-TLN4F+ (8 Core 35w Xeon D)
Chassis: Custom, probably
Drives: Samsung SM951 512GB M.2 PCI-e 3.0 x 4 NVMe, +3 SSDs
RAM: 64GB - 4x Samsung M393A2K40BB1-CRC - Samsung 16GB DDR4 2400MHz or
2x 32GB (MTA36ASF4G72PZ-2G3B1 or more expensive MEM-DR432L-CL01-ER24)

But need some pointers from someone who has experience of these boards,
Memory - Does 4x16GB give much/any improvement over 2x32GB due to extra bandwidth?
Would MTA36ASF4G72PZ-2G3B1 work, the SM tested part ends in A1 not B1.
Power - What's the best power supply for this setup? Will a Pico supply do?
Has anyone tried a 12v only supply? Would a TDK Lambda 100W/150W - LS100-12 LS150-12 work?

How much cooling to these boards need?

You should see no difference between 2x32 vs 4x16. Xeon-D is a dual-channel memory design.

Pico PSU should work fine.

Can't speak to the specific memory part number - sorry.

12v supply should work too but I've got no direct experience with it.

I use Samsung part number M393A2G40DB0-CPB0 (16GB) with all of my X10SDV boards.
I would look at the parts list for a X10SDV based board like the SYS-E300-8D for what they use for their 12V power supply. It'll give you a better idea of what is required.

Unless I am sure I will never need more, I use 32GB DDR4 RDIMMs now in these systems. There are a few where I know I will never use more than 64GB and so I will use 4x 16GB configurations. With an 8 core/ 16 thread chip, if you are doing virtualization and then decide you want ZFS you will likely arrive at 128GB at some point in the future making 2x 32GB a better option.

Many folks here are using Proxmox VE with these boards since you can have ZFS storage plus VMs and a nice Web GUI. It may be worth checking out if you have not decided on a potential Linux / KVM platform.

Great advice, thanks! I'll go for 2x32gb to allow expansion as it makes no speed difference.
I've not been able to find a UK source or spec for the SM 12v supply and don't want to damaging the board with an untested one. May go with a small ATX or pico. I'm guessing 100w to 120w should power the board, ram and SSDs, and may add fibre SPF module later.
