Frequently Asked Questions

What is the difference between SO-DIMM and DIMM?

SO-DIMM (Small Outline DIMM) is a smaller form factor used in laptops, compact servers, and mini PCs. Standard DIMM is used in desktop and rack server motherboards. They are not interchangeable.

Is ECC Unbuffered SO-DIMM compatible with all DDR5 platforms?

No — ECC Unbuffered SO-DIMM requires a platform that specifically supports ECC UDIMM SO-DIMM. Many consumer platforms support non-ECC SO-DIMM only. Verify your platform's memory specifications before ordering.

Can I use this module in a laptop?

While the SO-DIMM form factor fits laptop slots, ECC memory requires platform support that most consumer laptops do not provide. This module is intended for server and workstation platforms with ECC SO-DIMM support.

Whether you are expanding memory in a compact server, upgrading an Intel NUC Pro for ECC reliability, or deploying DDR5 ECC memory in an edge computing platform, the Samsung M425R4GA3BB0-CQK0L delivers the 32GB DDR5 capacity, ECC protection, and Samsung reliability your compact server demands.
