HP Pro Desktop Upgrade

This 4GB DDR3 module upgrades HP Pro 3115, 3125, 3130, 3135 and 3300 systems. It installs as a single 240-pin UDIMM running at 1333 MT/s with CL9 timing and 1.5V operation. The non-ECC unbuffered design matches the original factory specification for these workstations.

Replace Slower DDR3

It replaces any lower-capacity or slower DDR3 DIMM currently fitted in the listed HP Pro models. The jump is worth it when the existing memory limits multitasking or forces excessive paging on typical office workloads. Buyers needing ECC, registered modules or speeds above 1333 MT/s cannot use this part.

Sustained Office Loads

Under continuous use the JEDEC-standard 1.5V voltage keeps power draw stable without thermal throttling. The 2Rx8 organisation delivers consistent bandwidth for long document editing, web sessions or background backups. No heat spreader is fitted, so airflow in the chassis handles the thermal load.

Questions about this item

Will the 240-pin DDR3 module fit the DIMM slots on my HP Pro 3130?

Yes, the 240-pin UDIMM matches the desktop DIMM slots used by the HP Pro 3130 and the other listed Pro models.

What is the correct way to seat the module so the system recognises the full 4 GB?

Align the notch with the slot key, press down firmly until both side clips click into place, and verify the BIOS shows 4 GB at 1333 MHz.

Does the lack of a heat spreader mean I must replace the module sooner?

No, JEDEC-standard DDR3 at 1.5 V runs within thermal limits without a spreader; the module is rated for a limited lifetime of service.
