System-Specific Upgrade for Dell Laptops

This 16 GB DDR4 SO-DIMM module is built for the Dell Inspiron 15 5577, Precision 5520 and XPS 15 9560. It targets owners of those models who need a single 16 GB stick to reach the platform maximum of 32 GB across two slots. Buyers with other laptop lines or desktop boards cannot use this 260-pin form factor.

Sustained Operation at 1.2 V

Running at DDR4 2400 with CL17 17-17-17 timings, the unbuffered 2Rx8 module maintains its rated speed without a heat spreader. The low 1.2 V voltage keeps thermals steady during long workloads, so performance does not throttle under continuous memory pressure.

Straightforward Slot Installation

The stick inserts into any free SO-DIMM socket; no tools or firmware steps are required. Because the kit contains only one module, installers must match the existing stick’s speed and voltage to avoid mismatch errors. Systems already populated with two modules cannot accept this upgrade.

Preguntas sobre este artículo

Does the 1.2 V DDR4 2400 MHz module run cooler than higher-voltage memory during all-day use?

The 1.2 V operating voltage is the standard low-power level for DDR4 SO-DIMMs, so heat output stays minimal during continuous operation.

My Dell Inspiron 15 5577 has two slots — can I add this 16 GB stick alongside the original 8 GB module?

Yes, the laptop supports up to 32 GB across its two 260-pin slots, so a 16 GB module pairs with an existing 8 GB stick for 24 GB total.

Will the CL17 2400 MHz timing work automatically with the factory memory already in my Precision 5520?

The module uses standard JEDEC DDR4-2400 CL17 timings, so the system will configure it automatically at the common speed without BIOS changes.
