Meanwhile, Z390 motherboards have at most, four DIMM slots so this required 32GB DDR4 modules. ASUS has been working with G.SKILL in bringing these “Double-Capacity” DDR4 to the market.

We can't tell from the names if any of these models have both DDR5 and DDR4 slots, but we can expect MSI and ASRock to come up with similar arrangements. ASUS Z690 motherboards listed give you a ...
