DDR3 Server RAM & ECC Memory

Find DDR3 server memory by capacity, speed, ECC type, module format and rank.

Match the exact server's DIMM support and population rules. DDR3 is not interchangeable with DDR4 or DDR5.

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

Identify the DDR3 module before replacing it

Record the full label on an installed DIMM, including its part number, capacity, speed, rank and voltage designation. Confirm whether the platform uses registered, load-reduced or unbuffered ECC memory; a shared DDR3 generation does not make these module types equivalent. Check the manufacturer's supported memory list and installation order for the exact processor configuration.

For an expansion, work out the required final capacity and which slots are already occupied. Check the proposed combination of existing and additional modules before ordering, rather than choosing only by the number of free slots. Our DDR3 versus DDR4 server memory guide helps explain the generation distinction.

Plan a replacement or matching batch

Use the server memory upgrade guide to prepare the existing layout and proposed change. For several machines, send each platform, module part number and quantity through wholesale server memory, stating whether alternatives or a matching batch are acceptable.
