I have posted about this before, but I did not get an answer and I have found some more information.
I have a Huananzhi x79 8D motherboard with 8x8GB of DDR3 ECC memory and 2 x Xeon E5 2670 CPU:s.
The unraid dashboard lists my RAM to be 32GB (instead of 64GB). The system information as well:
M/B: HUANANZHI X79-8D Version VAA31 - s/n: MB-201903272019
BIOS: American Megatrends Inc. Version 4.6.5. Dated: 03/28/2019
CPU: Intel® Xeon® CPU E5-2670 0 @ 2.
