4GB DDR3 1333MHz Desktop Module

This 4GB DDR3 1333MHz module uses the 240-pin DIMM form factor and runs at the standard 1.5V. It is built as a non-ECC unbuffered stick with CL9 timing for everyday desktop workloads. The single 1Rx8 rank keeps the design simple for mainstream boards.

Thermals Noise and Power Draw

At the standard 1.50V the module draws only modest power and produces little heat during typical office tasks. Passive cooling from normal case airflow is sufficient because the low voltage and single rank limit thermal output. No active fan is required and acoustic impact is negligible.

Tested Compatibility and Support

Every stick is tested to meet the PC3-10600 specification before it ships, reducing the chance of boot issues. The part is listed as a direct replacement for the HP 497158-W01 reference, simplifying verification for that platform. US-based technical support is available for configuration questions.

Questions about this item

How do I install the 240-pin DDR3 DIMM, and which step do people often get wrong?

Align the notch on the module with the slot key, press down firmly until both side clips click into place. The step people miss is pushing hard enough to engage both clips; a single click means the module is not fully seated.

What maintenance or replacement will this 4GB DDR3 module need later?

No routine maintenance is required. If errors appear, run a memory diagnostic; the module either passes or it must be replaced as a single 4GB unit.

What limit shows up first under sustained use with this CL9 1.50V DDR3 module?

The 1333 MHz speed and CL9 latency are the fixed performance ceiling; sustained workloads cannot exceed the rated frequency or tighten the timings.
