Adding memory to Precision 5820 Tower gives me error 2000-0722

I am using a Precision 5820 Tower.​
I have added more memory, and when booting with Dell Reliable Memory Technology (RMT), I always get a “SupportAssist |Pre-Boot System Performance Check” and a Critical Error Mesasge of “2000-0722”.​
Can you please tell me how to solve this problem?​

The main parts of the configuration at the time of purchase are as follows​
OS: Windows 10 Pro Workstations​
CPU:Xeon W-2102 (parts no.T2K79)​
MEM:32GB (2x16GB) DDR4 2666MHz RDIMM ECC (parts no.VM51C)​

Non-genuine memory for this 5820,​
A-Tech 16GB RAM Samsung M393A2K43CB2-CTD | DDR4 2666MHz PC4-21300 2Rx8 1.2V ECC RDIMM 288pin​
and inserted them into memory slots 3 and 4.​

Now both BIOS and Windows recognize it as 64GB, but I always get a “2000-0722” error when booting.​
If I press “continue”, it starts up and 64GB is recognized in Windows, so I can use it,​
However, no matter how many times I reinsert the memory as per the remedy, it does not improve.​
I spent almost 4 hours in BIOS to check all the memory, but the result was no problem.​

Q1. Why does this warning appear?​
Q2. Is this always the case with non-genuine memory?​
Q3. If Dell Reliable Memory Technology (RMT) is turned off, the warning will probably not appear,​
 But is it possible to cause fatal problems such as unstable operation or file corruption?​
