Question 1

What is a DDR memory cross-reference?

Accepted Answer

A DDR memory cross-reference allows you to find equivalent memory modules from different manufacturers. For example, if you have a Samsung DDR4 8GB RDIMM, you can find the equivalent Micron or SK Hynix module with matching specifications (type, density, speed, voltage, ranks, ECC).

Question 2

How do I find an equivalent memory module for Samsung, Micron, or SK Hynix?

Accepted Answer

Use MemoryXRef to search by part number (e.g., M393A1G40DB0-CPB) or by specification (e.g., DDR4 RDIMM 8GB 3200). The tool instantly shows equivalent modules from all manufacturers including Samsung, Micron, SK Hynix, Kingston, Corsair, Apacer, ADATA, and Innodisk.

Question 3

What memory types does MemoryXRef support?
