Question RAM and MOBO

[Fed1]

OK I'm narrowing down my search for the perfect memory and have landed on MSI's QVL list for compatible memory by MOBO. My first question is, What is important, that the memory was tested with the MOBO or that the memory was tested with the CPU? Or both? If I were to chose 1 which one should it be?

Second question has to do with the number of DIMMS and speed. Here is what the list looks like and my 2 choices.

Vendor	Model	DDR	SPD Speed	Supported Speed	Chipset	Voltage	Sided	Size	1|2|4 DIMM

G.SKILL

F5-6000J3040G32GX2-TZ5NR

DDR5

4800MHz

6000 MHz

SK hynix M

1.4V

DUAL

32GB

√ | √ |

CORSAIR

CMT64GX5M2B5600C40 ver5.43.13

DDR5

4000MHz

5600 MHz

SK hynix M

1.25V

DUAL

32GB

√ | √ | √

The Gskill only has checkmarks in the 1|2 DIMM columns and the Corsair has checkmarks in all 3 DIMM columns 1|2|4. What do the checkmarks mean? Basically I want to start out with a 2X32GB kit and maybe eventually add another 2X32GB kit to achieve the 128 GBs the mobo holds. Do the checkmarks mean I can only do that with the Corsair and not the GSKILL?

Thanks

The QVL list applies to the motherboard.

But the QVL list is not complete. It just means those specific choices are known to work. Many others will as well.

Not sure about your other question....but the standard advice would be to buy 128 now if you need 128....rather than 64 now and 64 more later. Because there is some chance the first pair of 64 will not play nice with the second pair. Maybe you are prepared to take that chance...that would be a personal choice. Might work fine, but no certainty.

With motherboard model you can check to see which combinations G.Skill has validated:
