Intel Z790 motherboards listed with support for DDR5-6800 and DDR4-5333 memory

Intel Z790 motherboards support up to DDR5-6800 memory

These are some of the first details about support for Intel Z790 memory.

We have received documents for the upcoming MSI Z790 series of motherboards, including their specifications. The documents confirm that these motherboards will support JEDEC DDR5-5600 specs by default (for Alder Lake, that was 4800 MT/s).

MSI MEG Z790 series supports up to 6800+ MT/s in 1 DIMM per channel (1DPC) and 1 rank configuration. For 2-rank memory, that speed will drop to 6400 MT/s. For comparison, MSI’s premium Z690 MEG boards such as GODLIKE, ACE, or UNIFY support DDR5 memory up to 6666MT/s, while the high-end (MPG) segment goes up to 6400MT/s.

There will also be Z790 motherboards with DDR4 memory supporting speeds of up to 5333MT/s in 1DPC and 1R configurations. The fastest MSI Z690 DDR4 board supports up to 5200MT/s of memory.

Interestingly, none of the MSI X670E motherboards already listed on official websites have any memory specifications. So it cannot be said precisely whether the Z790 or X670E series supports faster memory, or maybe there is no difference at all.

In fact, neither ASUS, Gigabyte nor ASRock list memory specs, however Biostar does (thanks to dudulab for letting us know). According to X670E Valkyrie specifications, it supports DDR5-6000 overclocked memory.

AMD has not yet revealed details about its EXPO technology for DDR5 memory overclocking profiles. This information has not yet been shared by any board partner or even AMD.
