4 GB DDR3 1600 laptop module

This 4 GB SODIMM runs at DDR3 1600 with a CL11 latency and 1.35 V operation. It fits standard 204 pin laptop slots and is sold as a new single rank unit. Ideal for owners upgrading an older notebook that requires low voltage DDR3 memory.

Low voltage single rank build

The 1.35 V rating reduces power draw compared to standard 1.5 V modules while keeping the same 1600 MT/s data rate. Single rank organisation helps compatibility with chipsets that limit rank count per channel. The 204 pin edge connector matches the physical keying used by DDR3 laptop sockets.
