Targeted laptop upgrade

This 4GB DDR3L SODIMM module is built for HP Pavilion 17-E020Dx, 17-E019Dx and 17-E017Dx notebooks. It adds a single 4GB stick to one of the two available 204-pin slots. The unbuffered, non-ECC design matches the original system specification.

DDR3L voltage and speed limits

The module runs at 1.35V with a rated speed of 1600MHz (PC3L-12800) and CL11 timing. The platform supports dual-channel architecture across its two sockets, with a maximum memory ceiling of 8GB. Installing a single stick operates in single-channel mode until a second matching module is added.

Replaces slower or smaller DDR3 SODIMMs

This upgrade suits owners replacing a 2GB stick or a slower DDR3 module in the compatible Pavilion models. The jump is worth it when the system currently runs below 1600MHz or has less than 4GB total, provided the second socket remains free for a future matched pair to enable dual-channel operation.

Questions about this item

Should I choose the single 4 GB stick or add a second module to reach the 8 GB maximum?

The notebook has two SODIMM sockets and supports up to 8 GB total, so a second identical 4 GB stick will fill the second slot and enable dual-channel operation.

What does the 1600 MHz rating deliver once the module is installed?

The stick runs at DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timings at 1.35 V, giving the rated bandwidth when the system memory controller operates at that speed.

Does the 204-pin DDR3L SO-DIMM interface limit performance compared to newer standards?

The module uses the 204-pin DDR3L SO-DIMM form factor native to the supported HP Pavilion models, so it matches the platform’s memory controller without adapter or voltage mismatch.
