INTRODUCTION

    CUDIMM (Clocked Unbuffered DIMM) DDR5 RAM kits have been around for a couple of months already and even though currently only Intel supports them with their latest Z890 motherboards this will soon change (more Intel models on the way and AMD may also follow later on). On top of that thanks to speeds all the way up to 9000MHz-MT/s and higher CUDIMM kits are starting to become the number one choice of not only enthusiasts and professionals but also gamers. Still, not all CUDIMM DDR5 RAM kits are of such high frequencies, there are also cost-effective models like the latest 32GB 6400MT/s DDR5 Dual-Channel Kit released just a few weeks ago by Crucial.

    So, what is the latest CUDIMM technology and what does it do exactly? Well as included in the name CUDIMM modules are equipped with CKD (Clock Driver) components which help improve stability and performance by buffering all distributed signals. Since this basically means there's no longer need for XMP profiles on compatible motherboards (plug and play of sorts) and available speeds should soon surpass 10000MT/s CUDIMM kits are the perfect choice for demanding workloads such as AI computing, high-performance data processing, and machine learning. The 32GB DDR5 6400MT/s Dual Channel Kit by Crucial is their sole CUDIMM kit as of now (single 16GB modules are also available – XMP 3.0 and EXPO compatible) and is equipped with Micron single-die, single-side modules featuring a CAS latency of 52 and requiring just 1.1V. Unfortunately, since this is their entry-level line, the modules lack heatspreaders but even so thanks to their low voltage requirements they should still allow for a somewhat good overclocking headroom. As for warranty Crucial offers a lifetime limited one except from Germany and France where they offer a 10 year limited one.
