8GB DDR4 SODIMM for Dell Precision 3550

This SK hynix module delivers 8GB of DDR4 2666MHz memory in a 260-pin SODIMM form factor. It operates at 1.2V with CL19 latency and uses a single-rank 1Rx8 configuration. The unbuffered, non-ECC design matches the factory specification for the Precision 3550 mobile workstation.

Suits owners of listed Dell laptops and workstations

The module is validated for a wide range of Dell systems including Inspiron, Latitude, OptiPlex, Precision and G-series models listed in the compatibility data. Builders upgrading machines outside this validated list, or who require ECC error correction or registered buffering, should verify support before purchase.

Single specification that decides fit

The 260-pin DDR4 SODIMM interface at 2666MHz CL19 1.2V is the decisive factor; the slot must accept DDR4 SO-DIMMs at this speed and voltage with non-ECC unbuffered operation.

Points forts

  • 8 GB capacity for smoother multitasking
  • DDR4 2666 MHz speed for responsive performance
  • CL19 latency with 1.2 V operation
  • 260-pin SODIMM fits compatible Dell laptops
