[SOLVED] Which memory option should I choose with these specs?

Yes. It's quite a fine line. The 9900k/10700k/10900k are power hungry beasts, easily attaining in the 250w + range with locked cores at turbo speeds or higher. That takes some seriously beefy VRM's, mosfets, power delivery system and at least an 8pin EPS, but preferably the full 12pin (4+4, +4) EPS if overclocking. Most boards, especially the more budget boards, do not have the components nor the power capability to deliver that amount of power safely.

Vendors shortchange the lesser boards for 2 main reasons. First is that there's a cost difference in a lesser amperage mosfet. Might only be less than 10¢ per mosfet, but use millions of those every year, it adds up quick and cuts into profit margins.
Secondly, they feel if you can...

Z590 is compatible with a 10900k. That particular Z590 will last about as long as it takes to power up the pc and run the first stress test.

Compatibility isn't the issue. Ability is, and low/mid grade motherboards are simply not designed heavy duty enough to handle that cpus power requirements and demands for any length of time. Very similar concept was tried by AMD with the FX 8 core 125w cpus on a 95w 760g chipset. If you sneezed wrong, the VRM's roasted.

To allow that cpu to actually hit its boost ratings and not damage the board requires more power than that board can support. You can't cheap out on the motherboard with a cpu capable of over 250w boosts.

Max I'd use on that board would be an i5-10600k.

Gigabyte Aorus Master is an excellent board, used by top pro reviewers because it's that good. The Gigabyte Vision G is also nice. The Aorus Ultra isn't bad. The rest are questionable, using 50A DrMos mosfets or lower. Ok for a 10700k, but iffy for the 10900k.

That's a pretty fine line you're drawing . Compatible but, will only last until powered up....Ok, I stand corrected.

Secondly, they feel if you can afford the best cpu, you can afford a best motherboard, and not cheap out by buying a budget board. Or no one would buy the more expensive models if the cheapo's did the same job.

So the high dollar boards are built to handle upto the high dollar cpus, the low dollar boards built only to handle the lower dollar cpus.
