One of the gaming optimised DDR4 RAM from Kingston for Intel's chipset(s) Z490 & Z590 (using the 4th revision (released to market by 2020) of the RAM, 3rd revision differs in main timings). I'm getting solid stability on fully populated multi channel config (4x8GB) with XMP timings C19-23-23-42 @ 4000MHz. [Oct '22 CeeKay555]
