DDR5 SODIMM for Latitude 5431 5531

This OWC module adds 8GB of DDR5 4800 memory to Dell Latitude 5431 and 5531 laptops. It uses the standard 262-pin SODIMM form factor and runs at 1.1V with CL40 latency. The single-rank 1Rx16 design is unbuffered and non-ECC. It replaces Dell part numbers AB949333 and SNPMVK8PC/8G.

Verify slot count and maximum capacity

Check how many SODIMM slots your Latitude 5431 or 5531 provides and the maximum memory the system accepts. Confirm the existing modules are also DDR5 4800 so the new stick can run at its rated speed. The laptop must support 1.1V DDR5 non-ECC unbuffered memory for this upgrade to work.

Fits alongside existing DDR5 4800 modules

This 8GB stick occupies one SODIMM slot and leaves any second slot free for another module. It draws power at the standard 1.1V DDR5 level and requires no heat spreader clearance. The JEDEC-compliant design keeps the original warranty intact while adding capacity for multitasking and larger files.

Soalan tentang produk ini

Does the OWC 8GB DDR5 4800 module arrive as a single stick or a kit, and is any tool required for installation?

The package contains one 8GB 262-pin SODIMM; no extra parts or tools are needed for the Latitude 5431 or 5531 slot.

Should I choose this 8GB 1Rx16 CL40 stick or look for a 16GB alternative for my Latitude 5431?

This 8GB 1Rx16 module matches the Dell AB949333 spec; add a second identical stick later if you want 16GB dual-channel.

What does the 4800 PC5-38400 rating actually deliver inside a Latitude 5531?

It runs at JEDEC-standard 4800 MT/s with CL40 latency at 1.1V, giving the maximum supported DDR5 speed for that platform.
