HP 4GB DDR3 1333 Registered 240-pin desktop RAM

HP 4GB DDR3 Registered DIMM

This HP module provides 4 GB of DDR3 SDRAM running at 1333 MHz with a PC3 10600 rating. It uses a 240-pin DIMM form factor and registered signal processing for stable operation in compatible desktop systems. The single stick suits users adding capacity to workstations or servers that require registered memory. It is not for buyers who need unbuffered modules for standard consumer motherboards.

Registered signal processing and 240-pin layout

Registered buffering reduces electrical load on the memory controller, which helps reliability when multiple modules are populated. The 240-pin edge connector fits only DDR3 DIMM slots keyed for this generation. Day to day, the module installs like any DIMM but will not work in boards that accept only unbuffered memory. It is not for builders whose platforms lack registered-memory support.

Upgrade from lower-capacity registered DDR3

Replacing smaller registered sticks with this 4 GB module increases total memory without changing the registered topology your system requires. The jump is worth it when your workload hits the current limit and the motherboard has free DDR3 slots that accept registered DIMMs. It is not for users moving from unbuffered DDR3 or migrating to a newer DDR generation.
