6 channels per socket (2 controllers with 3 lanes each), 8 sockets, and 64 GB LR DIMMs.
128 DIMMs are $2-3k a pop.
192 sockets, 8 way, up to 24TB of ram w 128GB or 12TB with 64GB sticks:

If someone wants to throw more money on RAM to be slightly faster, that's a solution design-decision; it's doubtful Amazon would do that. If they are, great.
That's previous generation:
>Intel® Xeon® processor E7-8800 v4/v3 family
The articles states:
> All three sizes are powered by the latest generation Intel® Xeon® Platinum 8176M (Skylake) processors
You mention the 8176Ms in your original comment, too. The current SuperMicro product that supports those is https://www.supermicro.com/products/system/7U/7089/SYS-7089P... and that only has 96 DIMM slots.
> Intel® Xeon® Scalable Processors, 8S-3 UPI up to 10.4GT/s
> 96x 288-pin DDR4 DIMM slots
> Supports up to 12TB DDR4 ECC 3DS LRDIMM in 96 DIMM slots
I think you'll find that this is due to the limitations of the CPU itself:
> Max Memory Size (dependent on memory type) 1.5 TB
