Speed DDR2 400 (PC2 3200)

CAS Latency CL3

  • 4GB dual-channel kit doubles memory bandwidth for smoother multitasking
  • DDR2 400 MHz speed accelerates application loading and system responsiveness
  • CL3 latency at 1.8 V standard voltage ensures stable operation
  • 200-pin SO-DIMM form factor fits compatible laptop and AIO slots
  • Rigorously tested modules deliver dependable performance for everyday workloads

DDR2 400MHz SODIMM kit

This 4GB kit contains two 2GB DDR2 400MHz modules built to the PC2-3200 standard. It targets owners of older laptops, notebooks or all-in-one systems that accept 200-pin DDR2 SO-DIMM memory and need a straightforward capacity increase.

PC2-3200 speed ceiling

The modules run at 400MHz with CL3 latency and 1.8V, which is the native ceiling for the DDR2 400 interface. Systems limited to this speed cannot use faster DDR2 or later DDR generations, so the upgrade stops at this bandwidth.

Dual-channel 4GB headroom

The paired 2GB sticks enable dual-channel operation on compatible platforms, doubling theoretical throughput over a single module. 4GB total suits everyday multitasking and legacy applications, while memory-intensive workloads or modern operating systems will exceed the available capacity.
