OWC 4GB DDR3L SODIMM for HP TouchSmart 15

This 4GB DDR3L 1600 CL11 module upgrades HP TouchSmart 15 Series laptops that use DDR3 memory. It runs at 1.35V with a 204-pin unbuffered layout and single-rank 1Rx8 organisation. The part number is 1S6T31R804GB.

JEDEC and ROHS compliance plus lifetime warranty

The module meets JEDEC-standard PC3L-12800 timings and is ROHS compliant, making it a warranty-safe upgrade for the original system. OWC backs it with a limited lifetime warranty and free technical support from their in-house lab testing programme.

Simple DIY installation with matching module advice

Installation is a straightforward DIY task on most TouchSmart 15 units; OWC provides a basic installation video for guidance. They recommend using identical capacity, speed and manufacturer modules for optimal performance, so mixed configurations may not deliver the expected benefit.

Questions about this item

Will this 204-pin DDR3L SODIMM need any future replacement or maintenance once installed?

The module is a solid-state component with no moving parts or heat spreader, so it requires no scheduled maintenance; it only needs replacement if a memory error appears or you decide to increase capacity beyond this 4 GB stick.

What limit appears first when this CL11 1600 MHz module runs under sustained load?

The CAS latency of 11 cycles at 1600 MT/s sets the timing ceiling, so latency-sensitive workloads hit that timing wall before bandwidth or voltage constraints become an issue.

How much heat, noise or power does this 1.35 V unbuffered stick produce during all-day operation?

At 1.35 V the DDR3L module draws minimal power, generates very little heat and makes no noise, so it adds virtually no thermal or acoustic load to an HP TouchSmart 15 running continuously.
