I purchased a T430 from a 3rd party. I wanted to take the memory to 12x32GB. However, I get random errors in the BIOS not detecting modules in different banks. I have tried different CPUs and in different configurations (dual CPU and single and different models of CPUs) but it never fully detects the correct amount of RAM installed (yes, I reseated the RAM a bunch of times and changed the order). I thought it was the server so I purchased an identical server and RAM and it does the same thing (mostly reporting bank A4 and with different sticks installed in that bank).

The RAM modules are Hynix 32GB 2R4 PC4-2400T-RB1-11 (HMA84GR7MFR4N-UH) and Hynix 32GB 3Rx4 PC4-2400T-RB2-11 (HMa84GR7AFR4N-UH). The issue duplicates in 2 systems but it appears that one system likes the HMA84GR7MFR4N-UH better.

I have updated the BIOS as well as iDRAC to the current versions. My ultimate goal is to have dual CPUs with 384GB RAM running TrueNAS scale and 12x4GB (2 of them being parity) SAS 12gbps drives. However, this memory issue is driving me nuts.

What are the odds that I purchased 2 faulty systems with pretty much the same exact issues? 

Thank you in advance!
