Micron announced the launch of DDR5 clocked unbuffered dual in-line memory modules (CUDIMMs) for desktops and clocked small outline dual in-line memory modules (CSODIMMs) for laptops under its Crucial brand. Both modules comply with the design standards set by the JEDEC Solid State Technology Association and support a data transfer rate of 6400 MT/s. This is approximately 5% faster than traditional non-clocked DDR15 memory modules and more than twice that of DDR4 memory modules. Micron expects these memory modules to drive the computing performance of the next generation of AI PCs.
In addition to being the industry's first commercial DDR5 CUDIMM and CSODIMM memory module designs that meet JEDEC standards, Micron also emphasized that its designs have been verified by Intel and are available for public release soon.Core Ultra 200S series processors codenamed Arrow Lake, and can use 32GB chips to form 64GB CUDIMM and CSODIMM memory modules, allowing AI PC devices to use up to 256GB of memory module resources.
Micron explained that although current DDR5 memory modules can already cope with faster data transfer rates, it is difficult to ensure reliability and signal integrity under higher bandwidth and higher capacity conditions. The new CUDIMM and CSODIMM memory modules are an evolution of traditional UDIMM and SODIMM. Their feature is that the clock driver is directly installed on the memory module to stabilize the speed.
While most current systems rely on clock signals from the CPU, Micron integrates the clock driver directly into the memory module to improve electrical signal degradation and make memory data transfer faster and more stable.
Crucial's DDR5 CUDIMM and CSODIMM memory modules currently offer data transfer speeds of up to 6400 MT/s and come with a lifetime limited warranty in the 16GB capacity specification.
