I added a second pair of 2x8GB modules (G.Skill Ripjaws V Black 16GB DDR4 3200MHz CL16 1.35v Dual Channel Kit F4-3200C16D-16GVKB), because one local store had a very good price. So now I have 32GB of RAM.
CPU-Z reports all 4 modules as having Samsung chips.
Motherboard: MSI X570-A Pro.
Initially after I added the second pair of RAM, the PC did not boot. DRAM diagnostic LED was lit and I had 3 beeps. After trying only the new pair of memory modules, it was OK so I put back all 4 modules and this time it worked. So I guess I did not properly inserted one of the new modules (in my defense, I inserted the new memory modules with the PC still under the desk; also this board uses those memory slots with latches only on one end).
With A-XMP disabled, when all 4 modules were inserted, they would run at 1866. SPD speed should be 2133 in this case. With only 2 modules (only with "old" pair or only with new pair) they would run at the correct 2133.
With A-XMP enabled and 4 modules, it would correctly run at 3200 (voltage automatically set at 1.35V). Same as with only 2 modules.
This was with 7C37vH4 BIOS (AGESA ComboPI 1.0.0.3 ABBA).
I updated the BIOS to 7C37vH6 (ComboPI 1.0.0.4 Patch B) and with A-XMP disabled and all 4 modules it now runs at 2133.
No difference with A-XMP enabled (still running at 3200/1.35V).
So in my case 1.0.0.4 is an improvement.
Also the boot time decreased with about 4 seconds. Not that I care much about the boot time (as long as we are not talking about minutes or worse).
