Capacity and Compatibility

This 4GB DDR3 module runs at 1600MHz with CL11 latency and 1.50V operation. It is built as a single unbuffered DIMM using major-brand chips and targets desktop owners who need a direct replacement for specific Crucial part numbers.

Build and Connectors

The 240-pin DIMM fits standard desktop slots and uses the standard 1.5V DDR3 voltage. Non-ECC unbuffered design means it installs without server-grade requirements and works in typical consumer motherboards that accept this generation.

Upgrade Context

It replaces Crucial CT51264BA160B, BLT4G3D1608DT1TX0 and CT2KIT51264BA160B modules. The jump is worthwhile when a system has empty slots or slower DDR3 installed and the platform supports 1600MHz operation at CL11.
