Micron’s Crucial division has taken a significant step forward in PC memory technology with the launch of its new memory modules: CUDIMMs for laptops and CSODIMMs for desktops. These innovations are essential for meeting the increasing demands for faster memory speeds, particularly as Intel prepares to introduce its Arrow Lake chip.
The clocked unbuffered dual inline memory modules (CUDIMMs) and clocked small-outline dual memory modules (CSODIMMs) incorporate a clock driver circuit directly onto the module, moving away from the traditional approach where DIMMs depend on the CPU clock. This new architecture allows for impressive memory speeds of 6,400 megatransfers per second, a 15 percent improvement over standard DDR5 DIMMs. Specifically, these modules achieve DDR5-6400 speeds, thanks to the more precise timing enabled by the integrated clock driver.
While Micron is marketing these new modules primarily to those interested in AI, they are versatile enough to serve gamers and general users alike, especially those running demanding applications like high-speed large language model (LLM) chatbots.
Intel has officially validated these memory modules for use with its Arrow Lake processors, which are set to ship later this month. Micron has already begun shipping these new modules to PC manufacturers, with configurations available in 32Gbit modules that can support up to 256GB in Arrow Lake desktops. However, consumers will have to wait until the first half of 2025 to purchase these modules online, and no pricing information has been released yet. The modules will come with a limited lifetime warranty.
