Computer Memory Solutions 8GB (2x4GB) DDR3 1333MHz CL7 SODIMM Vostro 3550

System-Specific DDR3 Kit for Dell Vostro 3550

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for Dell Vostro 3550 notebooks. It uses the 204-pin form factor required by that platform. The memory runs at 1333 MHz with a CAS latency of CL7 and operates at 1.5 V. It is an unbuffered, non-ECC upgrade sold new in a matched pair.

Dual-Channel Pair Requirement

The Vostro 3550 has two memory sockets with a maximum capacity of 8 GB. Modules must be installed in pairs to enable dual-channel operation. This kit provides the exact matched pair needed to reach that limit. A 64-bit operating system is required to address the full 8 GB; otherwise the system may recognise only 3.5 GB or less.

Sustained Load Stability

Major-brand DRAM chips and a 7-7-7 timing profile deliver consistent throughput during extended workloads. The CL7 latency helps maintain responsiveness when the memory controller is saturated. Without a heat spreader, the modules rely on the notebook's internal airflow, which is sufficient for the standard 1.5 V operating voltage.
