DDR4 Server RAM & ECC Memory

Compare DDR4 server memory for capacity upgrades and replacement modules using speed, rank, ECC and module-type filters.

Confirm RDIMM or LRDIMM support and supported capacities for your server. DDR4 cannot be installed in DDR3 or DDR5 slots.

Hardware supplied by KahnServers includes a 90-day warranty. Check current availability and the individual product specification before ordering.

Choose DDR4 memory for the complete layout

Start with the server model, processor configuration and current DIMM labels. Record the capacity per module, speed, rank and registered or load-reduced format. Check supported capacities and slot population rules in the platform documentation; the speed printed on a DIMM does not by itself establish the speed at which a proposed server configuration will run.

For an upgrade, compare the number of modules you need with the slots available and the desired final capacity. Browse 32GB DDR4 RDIMMs and 64GB DDR4 RDIMMs only where those capacities and the registered format are supported by the target system.

Confirm compatibility before placing a batch order

Our server memory compatibility guide explains the details to collect before selecting modules. For a repeat deployment, use wholesale server memory with the exact part numbers, quantities per server and existing layout, so the proposed supply can be checked against the requirement.
