OWC 8GB DDR5 4800 CL40 1Rx16 262-pin 1.1V Non-ECC SODIMM for Latitude 5431 5531

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.
