The x3950 X6 server can be used as 4/6/8 socket server if top and bottom half IMM2 boards are powered.
And it can be used as a 2/4 socket server if only the bottom half is powered.
Since now with 1TB installed every compute board has 8 RAM modules with best balanced 1:1:1:1:1:1:1:1 config, the server can be run as 2/4/6/8 socket server with always best possible balanced memory config without any RAM module changes.
I did buy the RAM modules from ebay for being able to have contiguous 2^40 bytes array, but the much increased memory bandwidth could not have been achieved with 16GB RAM modules and less than 1TB on x3950 X6.
P.S, regarding being a student of Heidelberg University now:
I bought the Pi5 two years ago because of the free Wolfram license for Raspberry computers.
Today I provided my student email address on Wolfram website and got this response:
Ruprecht Karls Universitaet Heidelberg Has Access to Wolfram Products
So I will be able to install Wolfram products on my 8-socket Intel server as well ...
