OWC 4 GB DDR4 SODIMM for HP Pavilion Gaming

This 4 GB DDR4 2400 MHz SODIMM module is built for the HP Pavilion Gaming 15-ec series laptops. It suits owners of the 15-ec0003nf, 15-ec0003nl, 15-ec0004nf, 15-ec0004ns and 15-ec0005ng models who want a straightforward capacity increase. The stick is unbuffered, non-ECC and runs at 1.2 V.

DDR4 2400 CL17 limits on laptop platforms

The DDR4 2400 standard tops out at 19200 MB/s theoretical bandwidth with a CL17 latency cycle. A single 4 GB rank cannot populate dual-channel mode on its own, so peak throughput stays at single-channel rates. The JEDEC voltage of 1.2 V is fixed and the module has no heat spreader for thermal headroom.

Check slot count and maximum memory before ordering

Verify how many SODIMM slots your specific Pavilion Gaming 15-ec unit exposes and what total capacity the firmware allows. Some configurations ship with both slots filled, requiring a pair replacement rather than a simple add-in. Confirm the existing stick speed matches 2400 MHz to avoid down-clocking.

Questions about this item

Should I pick this 4 GB module or a larger capacity for my HP Pavilion Gaming 15-ec series?

This module provides 4 GB of DDR4 2400 memory; if your laptop has two slots you can add a second identical stick for 8 GB total, matching the 1Rx8 rank and CL17 timing.

What does the 2400 MHz rating actually deliver once installed?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency at 1.2 V, giving the rated bandwidth and timing the HP platform expects without downclocking.

Is the 260-pin SODIMM interface the limiting factor for speed or capacity?

The 260-pin DDR4 SODIMM form factor carries the 2400 MT/s signal and 1Rx8 organisation; it does not impose a lower ceiling than the module’s own 2400 MHz rating.
