I am having trouble finding, or perhaps just not comprehending, what memory for what board? Do all the DDR4 memories work for all the boards?

For reference, MSI X99S SLI Plus is the board I am looking at most.
Saw a few memory on main site was PC4-17000. Newegg comboed it with 22400. If it isn't listed on site, should it be bought?

Anyone know which should be bought, and if Newegg is just mistaken or worse yet...

In theory, all DDR4 memory modules should be compatible with all motherboards that support DDR4. In practice, slight [almost always unintentional] deviations from the JEDEC standards on behalf of the memory manufacturer (Samsung, Hynix, Micron), memory module manufacturer (Corsair, Mushkin, G.Skill, etc...), motherboard manufacturer (Asus, Gigabyte, MSI, etc...), CPU/chipset manufacturer (only Intel at this point), or upstream firmware designer (American Megatends, Insyde) can cause problems. There are an enormous number of points of failure and all it takes is one. This is not a new problem, it has been a problem ever since motherboards began supporting modular memory.

well, if in theory it should, than I will have to hope for the best. Thank you for your response Pinhedd.


Though, since I might still have this open for questions, might as well ask an extension of this question. If I buy 1-2 or have 5-6 memory sticks, (lets say for bigger numbers, 4 are the same) should they all be bought as same company, speeds, etc? (Is this similar to sli and such?)

Could I have 1-4 being the better, and a kit, together and something that will come out in a year, with #5 and #6 sticks being my starter sticks. Will any problems, or rather, any form of an anomaly occur from this method?

Even further, will problems occur just have 1-2 sticks at 8 gbs each (16 total), rather than 4 sticks at 16gbs overall?
 


Leaving this open is probably a good idea. Testimonials should start coming out in a few days.

As for mixing and matching sticks...

Mixing and matching sticks has always been a bad idea. It's usually fine to do so in low and mid range servers because those modules are designed with RAS in mind. PCs on the other hand are often treated much more liberally, so interoperability issues, while rare, do arise.

If you have the opportunity to purchase the exact same model then that would be best. Matched kits, while nice, are a bit over rated.
