Laptop DDR5 32GB SODIMM

This 32GB DDR5 module uses the 262-pin SO-DIMM form factor and runs at 4800 MT/s with CL40 latency. It operates at the standard 1.1V and is unbuffered non-ECC, making it a direct replacement for the Samsung M425R4GA3BB0-CQK part. The module is designed for laptops, all-in-one PCs and NAS systems that accept DDR5 memory.

Fits DDR5 SO-DIMM slots only

Buyers whose systems require DDR5 SO-DIMM memory at 4800 MT/s and 1.1V will find this module matches those specifications. It is not suitable for desktops that use 288-pin DIMMs, for platforms that mandate ECC or registered memory, or for machines that cannot accept a 2Rx8 density configuration. Systems limited to lower-speed DDR5 grades should verify compatibility before purchase.

4800 MT/s CL40 DDR5 speed grade

The single specification that determines fit is the DDR5 4800 PC5-38400 CL40 rating combined with the 262-pin SO-DIMM form factor and 1.1V operation. If the target device lists this exact speed grade, pin count and voltage, the module will install and run at its rated timing. Any deviation in speed, pin layout or voltage means the part will not function correctly.

Questions about this item

What comes in the box with the OWC 32GB DDR5 4800 SODIMM, and do I need any extra parts to install it?

The box contains the single 32GB DDR5 4800 CL40 262-pin SODIMM module. No additional parts are required; installation uses the laptop's existing memory slot and a small screwdriver.

How do I decide between this 32GB CL40 module and other capacities or speeds listed for my laptop?

Choose this 32GB module when your system supports DDR5 4800 and you need the maximum single-stick capacity; lower capacities cost less but limit total memory, while higher speeds only help if the platform runs them natively.

What does the 4800 MT/s rating actually deliver once the module is seated in a real machine?

The module runs at the JEDEC-standard 4800 MT/s with CL40 latency at 1.1 V, giving the bandwidth and responsiveness the platform's memory controller is designed for without overclocking.
