CUDIMM Standard Set to Make Desktop Memory a Bit Smarter and a Lot More Robust

h & Anton Shilov on June 21, 2024 10:30 AM EST While the new CAMM and LPCAMM memory modules for laptops have garnered a great deal of attention in recent months, it's not just the mobile side of the PC memory industry that is looking at changes. The desktop memory market is also coming due for some upgrades to further improve DIMM performance, in the form of a new DIMM variety called the Clocked Unbuffered DIMM (CUDIMM).

DDR5 allows for rather speedy transfer rates with removable (and easily installed) DIMMs, but further performance increases are running up against the laws of physics when it comes to the electrical challenges of supporting memory on a stick – particularly with so many capacity/performance combinations like we see today. Meanwhile, phase adjustment capabilities allow CKD to align the clock signal with the specific timing needs of different components, which means some additional work on the memory module maker's side. Finally, unlike some of its rivals, V-Color seems to be taking some serious advantage of CKD chips for high-performance memory offerings, as it showcased both CUDIMMs and CSODIMMs at the trade show.
