Micron has announced that it is expanding its portfolio with clock driver memory, a brand-new category of memory products that comprise Crucial DDR5 clocked unbuffered dual inline memory modules (CUDIMM) and clocked small outline dual memory modules (CSODIMM), JEDEC-standard solutions that are advertised to run at speeds of up to 6,400 MT/s (megatransfers per second). This level of performance is not only 2x as fast as DDR4, but 15% faster than traditional, non-clock-driver-based DDR5, Micron noted in a press release that it shared today. The CUDIMM and CSODIMM solutions in 16 GB capacities will be available for purchase through Crucial.com, while 64 GB kits will be available in H1 2025.
While DDR5 offers rapid speeds, scaling challenges have made it difficult to deliver DDR performance increases while ensuring reliable high speeds and signal integrity, especially when combining high bandwidth with large capacity. Representing an evolution of traditional UDIMMs, the new category of CUDIMMs and CSODIMMs feature a clock driver directly on the memory module to stabilize speeds. While most systems today rely on the clock from the CPU, using innovative engineering, Micron has directly integrated the clock driver into the memory module to conquer electrical challenges at the root, making memory faster and more stable.
The 6,400MT/s speeds provided by Crucial’s plug-and-play DDR5 CUDIMM and CSODIMM memory offer an out-of-the-box performance boost to AI PCs and other data-hungry workloads, whether users are upgrading from a DDR4 system or looking to increase DDR5 performance. The CUDIMM solutions are suited for desktop computers and the CSODIMM solutions for laptops.
