16GB DDR4 SODIMM for Dell G3 Gaming

This 16GB DDR4 2666MHz SODIMM module targets owners of Dell G3 15 (3579) and G3 17 (3779) Gaming laptops who need more memory for multitasking or gaming. The single stick delivers 16GB capacity at CL19 timings. It is not for buyers who want ECC error correction or registered buffering. It is not for systems that require a different pin count or voltage.

Fits two SO-DIMM slots up to 64GB total

The laptop provides two 260-pin slots supporting a maximum of 64GB, so this 16GB stick can be installed alone or paired with another module. It runs at 1.2V unbuffered without a heat spreader, leaving clearance in tight chassis. Builders who need quad-channel bandwidth or desktop DIMM form factor cannot use this module.

Single stick with lifetime exchange warranty

The package contains one memory stick backed by a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly from the manufacturer. A 30-day money-back guarantee is also offered. No software utilities, drivers or additional accessories are bundled.

Questions about this item

Will the CL19 timing limit throughput during long sessions?

The module runs at CL19 19-19-19 timings at 2666 MHz; sustained throughput is determined by that latency and the memory controller.

How much heat or power does the 1.2 V unbuffered stick produce all day?

It operates at 1.2 V without a heat spreader; power draw stays at standard DDR4 SODIMM levels and the laptop cooling handles the heat.

Which Dell G3 models accept this 260-pin DDR4 SODIMM?

Compatible with Dell G3 15 (3579) Gaming and G3 17 (3779) Gaming, each supporting up to 64 GB across two sockets.
