Buying guide: DDR3 Memory for Servers, Desktops & Laptops

Find DDR3 memory by capacity, speed, ECC type, module format and rank. The category covers server DIMMs and laptop SODIMMs, which are not interchangeable. Match the part number and memory format to your machine before ordering.

Identify the DDR3 module

Record the full label on an installed module, including part number, capacity, speed, rank and voltage designation. Servers may need registered, load reduced or unbuffered ECC memory, with platform specific population rules. Laptops require the correct SODIMM form factor and supported voltage.

Check the manufacturer’s memory support list for the exact model and processor. DDR3 is not interchangeable with DDR4 or DDR5. Our DDR3 versus DDR4 guide explains the generation difference, while the server memory upgrade guide covers preparation for a server upgrade.

Match a replacement or batch

Compare individual listings for condition and current availability. For several machines, provide the system model, module part numbers and quantities through wholesale server memory.
