Does anyone have the H board?
The documentation is all over the place in terms of Max memory speed.
The box states 4000 but the booklet inside says 3866
Even Asus site shows both numbers.

Which one is actually true? If it's not 4000 I need to return this board.
I can't test it myself until my CPU is delivered 4 days from now...

Whatever it is, take at least two ratios off. The max supported speed is always conditional and optimistic. DDR4-3600 to DDR4-3733 is where I expect most four-slot boards to top out for the masses. Higher speeds require a good CPU, memory kit, and that the user is adept at tuning memory settings.

Most users purchase good memory kits; the motherboard spec advertises something like DDR4-4000 so they buy something like DDR4-4000.
But yeah, a good CPU and properly tweaked memory configuration are required.

A question about the QVL ...

When, for instance, a particular 4x8GB DDR4-3600 kit is listed and "4 DIMMs" is specified, does that mean it was tested as 4x8GB DIMMs operating at rated XMP DDR4-3600 frequencies? Or just that all four DIMMs from that kit part/model can be recognized and addressed at natively-supported JEDEC SPD?
