I have only heard about up to 8-channel memory so far on the newest servers.
Searching for Dell 7920:

Intel Xeon Scalable Processor CPU installed
To get 6-channel memory, I think you need to install 6 DIMMs in every 2nd slot or all 12 DIMMs, and it should be the exact same type of RAM.


Try CPU-Z: https://www.cpuid.com/
You do not have to install anything, there is a zip file with CPU-Z:

Just run the "cpuz_x64.exe" and on the Memory tab it will show you how many memory channels you use, mine is running 4-channel memory (quad):
