DDR5-6400 CUDIMM 32GB

Background on DDR5 Clocked Memory

DDR5 is the fifth generation of 'double data rate' memory technology. It features reduced power consumption compared to previous generations, while also boosting clock speed and memory density. That means both higher performance and lower power usage, with the potential for larger memory modules as the standard matures.

A new development with DDR5 is a type of module being called CUDIMMs. The "C" there stands for "Clocked", which refers to the fact that these sticks of memory include a clock driver right on the module. That helps keep the data signal synced with the memory controller on the CPU, allowing for higher frequencies by minimizing jitter and overall improving signal integrity.

Due to market volatility, the exact brand and model of memory that we use can vary - but we adhere to strict quality standards and prioritize modules that use Micron or Samsung chips.

Please note that the actual speed at which memory modules will operate in any given system is a combination of several factors: the memory specs, official CPU-supported speeds from Intel & AMD, motherboard memory QVLs, and what we have found to work the best in our internal testing and qualification. If you have questions about what frequency the RAM in your Puget system will be set to, please contact your sales consultant.

William George (Go-To-Market (GTM) Manager) Says:
CUDIMMs are a new variant of DDR5 memory modules, and at launch they are only supported by Intel Core Ultra processors. The higher clock speeds they enable aren't a huge deal, but can provide a small boost in performance in some applications (up to ~5% for 6400 vs 5600, for example). That full speed can only be reached with just 2 memory modules installed, though!
