4GB DDR3 1600 Module for HP Pavilion

This 4 GB DDR3 1600 CL11 unbuffered DIMM is built for HP Pavilion 500-B23W, 500-C00Z, P6-2480Ea and P6-2420L desktops. It runs at 1.5 V with 11-11-11 timing and uses a 2Rx8 rank layout on a 240-pin interface. The single stick adds 4 GB of non-ECC memory to compatible systems.

Upgrade Path from Lower Capacity or Speed

The module replaces slower DDR3 modules or smaller capacity sticks in the supported Pavilion models. It is worth fitting when the board has a free 240-pin slot and the current memory runs below 1600 MHz or totals less than the 16 GB maximum the platform accepts. Builders needing ECC, registered buffers or speeds above 1600 MHz should look elsewhere.

Steady Operation at Rated Speed

Under sustained load the stick maintains its 1600 MHz data rate and CL11 latency without a heat spreader. The 1.5 V supply keeps power draw predictable during long sessions. Stability relies on the system's own airflow since no dedicated cooling is present on the module.

Questions about this item

Will the 240-pin DDR3 module fit the HP Pavilion 500-B23W DIMM slots?

Yes, the 240-pin DDR3 DIMM matches the HP Pavilion 500-B23W memory slots and the system accepts up to 16GB total across two sockets.

What is the correct way to seat the unbuffered DIMM so the motherboard recognises the full 4GB?

Align the notch on the module with the slot key, press down firmly until both retention clips click into place, then verify 4GB appears in BIOS.

Does the 1.5V CL11 stick need any firmware updates or periodic cleaning to keep its lifetime warranty valid?

No firmware updates are required; keep the gold contacts free of dust and the module will remain covered by the manufacturer’s limited lifetime warranty.
