OWC 8GB DDR4 2133MHz SODIMM for Dell XPS 15 9550

This 8GB DDR4 module is built specifically for the Dell XPS 15 9550 laptop. It uses a 260-pin SODIMM form factor and operates at 1.2V without ECC or a heat spreader. The unbuffered, dual-rank design meets JEDEC standards for a direct, warranty-safe memory upgrade.

8GB capacity handles everyday multitasking

The single 8GB stick boosts responsiveness when opening multiple applications or working with bigger documents. It runs at DDR4 2133MHz with CL15 latency, matching the system's native memory speed. Total capacity remains limited to the number of slots available in the laptop.

260-pin DDR4 SODIMM interface decides fit

Only systems accepting 260-pin DDR4 SODIMM modules at 2133MHz can use this part. The Dell XPS 15 9550 is the validated platform; other laptops, mini desktops or NAS units require separate compatibility checks. Buyers needing ECC, registered DIMMs or a different pin count must choose another module.
