Memory - RAM

System memory plays a direct role in how responsive and capable a PC feels day to day. It handles active data for your operating system, applications, and games, allowing tasks to load faster and run smoothly without relying on slower storage. Whether you are refreshing an older machine or specifying parts for a new build, choosing the right memory can make a noticeable difference.

This category includes DDR4 and DDR5 kits in a range of capacities, speeds, and latency profiles, suited to everything from general home use to high-end gaming, creative workloads, and professional software. Faster frequencies and tighter timings can improve performance in supported systems, while larger capacities are ideal for multitasking, video editing, and demanding productivity tools. Compatibility with your motherboard and processor is just as important as raw speed.

DDR5 Server RAM Memory Kits 6400MHz+

Computer memory, or RAM (Random Access Memory) is used by CPUs to run applications and host VMs. Generally speaking, the more RAM your server or workstation has the faster it will run as well as being able to support more users. Server RAM differs from standard unbuffered DIMMs for desktop PCs by supporting ECC and Registered functionality for greater reliability, and is available in much higher capacities.

DDR5 is the latest type of system RAM available and is supported by a wide range of AMD EPYC, AMD Ryzen Threadripper PRO and Intel Xeon processors and in this category you'll find a variety of DIMMs for servers and workstations, capable of running at 6,400MHz or higher in various capacities.

Make sure to choose RAM that is compatible not only with your system's CPU(s) but also the system itself; reputatable server and workstation manufacturers publishing lists of certified memory on their websites or on request.
