Expect to see new RAM modules with huge boosts in speeds in the coming months, as a new class of DDR5 RAM has emerged to enable significantly faster clock speeds. It’s called CUDIMM – short for Clocked Unbuffered Dual In-Line Memory Module, which is a subset of current desktop standard, UDIMM.
CUDIMM Enables Up To 10,000MT/s
The main feature of CUDIMM modules is a dedicated clock driver on the memory modules themselves – this additional chip allows the clock speed to maintain stability at higher speeds. Better stability means more headroom to push for faster modules, and there are models already advertising speeds at 9200MT/s, some even higher. (It’s worth noting that the JEDEC default for CUDIMMs fall on 6400MT/s, as opposed to 4800MT/s on DDR5 UDIMMs.)
According to leaker MebiuW, Intel’s Arrow Lake-S lineup (Core Ultra 200 desktop) will be capable of supporting CUDIMMs via Gear 2 – meaning, the integrated memory controller maintains a 1:2 ratio to the memory modules, since IMCs for Intel’s current crop of chips pretty much can’t run at speeds beyond 8000MT/s natively. What about AMD? No signs thus far, and it’s unclear if AMD has implemented CUDIMM support for its X870 motherboards and the new Ryzen 9000 chips.
In the near future, these modules are expected to break the 10,000MT/s barrier, and it’ll be interesting to see how far can motherboard makers push these modules for their designs. Extreme overclockers may be rubbing hands as we speak…

Pokdepinion: One does wonder if Ryzen CPUs today are capable of supporting these new modules via 1:2 ratio as well.
