I recently purchased a Xeon E5-2678v3 kit with 64Gb of DDR4 2133 and a Huananzhi x99-f8 board. The thing is that the board detects a maximum of 32Gb of RAM when I mount the 4 modules in the arrangement recommended by the manufacturer for QuadChannel. I have mounted a GTX-745 as graphics card and a 500Gb NvME Sabrent-rocket as disk (I want it as a virtualization environment, not as a gamming device).
I am not sure if it is the memory modules that have arrived badly, if I have something in the BIOS that is not configured correctly or if it is some hardware incompatibility. I have tested the board by installing W10 and it works correctly, maintaining very good temperatures and withstanding the CPUz stress test without any problem.
Can you think of something?
