Buying guide: DDR4 Memory for Servers, Desktops & Laptops
Browse DDR4 memory by capacity, speed, rank and module type. This category includes registered server RDIMMs, load reduced server LRDIMMs, desktop UDIMMs and laptop SODIMMs. Choose the correct form factor and electrical specification for the machine rather than selecting by DDR generation alone.
Choose the right DDR4 module
For a server, compare RDIMM and LRDIMM support with the exact platform and processor configuration. For a laptop, browse DDR4 SODIMM memory and check its supported capacity and speed. For a desktop or workstation that needs unbuffered memory, see UDIMMs.
Record the existing module’s part number, capacity, speed, rank and ECC status. Check slot population rules and firmware support before mixing modules or planning a batch upgrade. DDR4 cannot be installed in DDR3 or DDR5 slots.
Find server memory by capacity
For supported registered configurations, browse 32GB DDR4 RDIMMs and 64GB DDR4 RDIMMs. Our server memory compatibility guide explains what to check, and wholesale server memory covers repeat deployments with specified quantities and part numbers.
