Server DDR4 2666MHz RAM Memory Kits

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.

DDR4 is an older type of system RAM 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 2,666MHz 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.
