32GB DDR5 4800 SODIMM for Latitude

This 32GB DDR5 4800 CL40 SODIMM is built for Dell Latitude 5431 and 5531 laptops. It runs at 1.1V with a 2Rx8 layout and fits the 262-pin slot. The module is JEDEC compliant and requires no heat spreader.

Suits single-slot upgrades on supported models

Owners of a Latitude 5431 or 5531 who need a single 32GB stick will find this module fits the factory slot. Systems that require ECC memory, registered DIMMs or a different pin count cannot use this part.

262-pin DDR5 form factor decides fit

The 262-pin DDR5 SODIMM form factor is the only physical interface that matches the Latitude 5431 and 5531 memory sockets. Any module with a different pin count or DDR generation will not seat in these laptops.

Questions about this item

What does the 4800 MHz speed mean once the module is installed in a Latitude 5431 or 5531?

The module runs at the JEDEC-standard 4800 MHz DDR5 rate, delivering PC5-38400 bandwidth with CL40 latency for faster multitasking and large-file handling.

How does the DDR5 SODIMM interface limit performance in practice?

The 262-pin DDR5 SODIMM slot caps the module at the JEDEC 4800 MHz specification; no higher XMP or overclock profiles are supported on these Latitude models.

What physical space does the 262-pin SODIMM need to fit inside the laptop?

It uses the standard 262-pin DDR5 SODIMM form factor with no heat spreader, so it fits the single memory slot in the Latitude 5431 and 5531 chassis.
