Compatible HP Pavilion Notebook Upgrade

This 4 GB SODIMM is built for the HP Pavilion 20-B002La, Dv4-5012Tx and Dv4-5101Tx notebooks. It installs in a 204-pin DDR3 slot and runs at 1600 MHz with CL11 timing at 1.5 V. The single module provides a straightforward capacity increase for those specific models.

Suitable For Single-Slot Expansion

The stick suits owners of the listed Pavilion models who have a free slot and want to add 4 GB without enabling ECC. Buyers whose laptop accepts only 1Rx8 modules or requires registered memory should look elsewhere, as this unit is unbuffered 2Rx8.

2Rx8 Rank Determines Slot Compatibility

The module uses a 2Rx8 organisation, meaning each rank presents eight data lines across two ranks. Some Pavilion platforms only accept single-rank parts, so verifying the rank requirement before purchase decides whether this upgrade will be recognised.

Questions about this item

Is this single 4 GB stick the right choice for my HP Pavilion 20-b002la or dv4 notebook?

Yes, the module is validated for the Pavilion 20-b002la, dv4-5012tx and dv4-5101tx, and each notebook has two slots supporting up to 16 GB total.

Will the CL11 timing at 1600 MHz actually run at that speed in my laptop?

The stick is rated DDR3-1600 (PC3-12800) with 11-11-11 latency; the system will operate it at the highest speed the platform allows.

Does the 204-pin DDR3 SO-DIMM interface limit the bandwidth I can get?

The 204-pin DDR3 SO-DIMM form factor carries the PC3-12800 data rate, so the practical ceiling is the 1600 MHz specification of this module.
