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.

Questions about this item

Does the DDR3-1333 interface cap memory bandwidth at the PC3-10600 rating?

Yes, the module runs at 1333 MHz and is rated PC3-10600, which defines the maximum transfer rate for this DDR3 standard.

Will the 240-pin registered DIMM fit a standard desktop motherboard slot?

It requires a DDR3 DIMM slot that supports registered modules; the 240-pin form factor matches the slot, but the motherboard must explicitly accept registered memory.

What is the correct installation step for this registered DDR3 module?

Align the notch on the 240-pin edge connector with the key in the DDR3 slot, press straight down until both retention clips click, and verify the motherboard recognises the registered module in BIOS.
