MSI and ADATA recently collaborated on a new feature update for memory modules. This upgrade involves modernizing the existing CUDIMM design from 2 ranks to 4 ranks, offering larger capacities up to 128 GB per module.
And that, essentially, would double the memory capacity of existing platforms while maintaining fast CKD implementation. Now, the information is that it is not just MSI that is working on this new memory module solution.
One of the reasons other manufacturers are working on this design is JEDEC, which plans introduce technology as a new standard called CQDIMM. Although CUDIMM currently supports 2-rank CKD, the CQDIMM will support 4-rank CKD.
In this case, the “Q” stands for Quad. And the advantage of CKD (Clock Driver) is that these modules must maintain speeds of 7200 MT/s, which will be natively supported by next generation platforms.

According to Benchlife, other motherboard manufacturers, such as Gigabyte and ASUS, are also working to enable support for 4-rank DDR5 memory modules on current and future motherboards.
Support is currently restricted to high-end overclocking designs. Examples are Dual-DIMM Unify X from MSI, Tachyon ICE from Gigabyte and Apex from ASUS. However, there will likely be more motherboards supporting the technology in the future.
For those interested in these high-end cards (or for those who want a price estimate), a Z890 AORUS Tachyon ICE is available for R$6,605.91 on Amazon. ASUS models cost R$4,616.85 (ASUS ROG Maximus Z890 Apex) to R$8,150.39 (ROG Crosshair X870E Apex).
Additionally, based on available information, Intel’s Arrow Lake-S Refresh, which will be released for desktops and laptops early next year, will be the first platform to utilize the CQDIMM DDR5 standard.
Availability
However, 128 GB memory modules will be quite expensive. Not only because of their value, but because of the increase in memories that is happening in the world.
Thus, a reasonable scenario is for Arrow Lake-S Refresh to serve as a testing ground for the CQDIMM memory standard. Therefore, it will only receive broader support when the market normalizes around the launch of Nova Lake-S processors in the second half of 2026.
CES 2026 is just around the corner, so more will likely be said about this technology in the coming weeks.
