MSI has just launched four new AMD X870 and X870E motherboards: the flagship MEG X870E GODLIKE, MPG X870E CARBON WIFI, MAG X870 TOMAHAWK WIFI, and PRO X870-P WIFI. However, only the two top-tier X870E boards feature support for CUDIMM memory (UDIMM equipped with CKD clock driver chips).

MSI’s High-End X870E Motherboards Support CUDIMM RAM — But With a Catch-3CGO

But there’s a caveat: while these boards support CUDIMM, they only operate in CKD bypass mode. This means users won’t benefit from the full advantages of CKD technology, such as enhanced signal integrity and reliability at higher data rates.

The impact is evident in the overclocking capabilities of these boards. Despite CUDIMM memory having the potential to overclock beyond 9000 MT/s, the MEG X870E GODLIKE and MPG X870E CARBON WIFI top out at 8400+ MT/s — the same limit as the MAG X870 TOMAHAWK WIFI, which lacks CUDIMM support entirely.

While CUDIMM offers promising potential, MSI’s implementation limits its effectiveness on these boards, making the feature more of a spec sheet highlight rather than a game-changing performance boost — at least for now.
