Dell G5 15 and G7 15 memory upgrade

This 16 GB kit contains two 8 GB DDR4 SODIMM modules rated at 2666 MHz with CL19 timings. It is built for Dell G5 15 (5587) Gaming, G7 15 (7588) Gaming and Inspiron 27 7000 (7777) systems that use 260-pin SO-DIMM slots. The unbuffered, non-ECC design matches the factory specification for these laptops and the all-in-one desktop.

16 GB capacity and 2666 MHz headroom

Two slots are filled by this kit, reaching the 32 GB maximum supported by the listed Dell models. Everyday multitasking, browser tabs and office suites run comfortably within the 16 GB total. Demanding video editing, large virtual machines or heavy rendering workloads will exhaust the available memory and require the full 32 GB limit.

Two matched sticks in the package

The box supplies a matched pair of 8 GB modules so dual-channel operation is enabled immediately. No heat spreaders are included, keeping the low-profile form factor required by slim Dell chassis. Installation is a simple slot-in procedure with no extra cables, brackets or software to configure.

Questions about this item

Will the 2666 MHz DDR4 SODIMMs work alongside the original memory in my Dell G5 15 (5587)?

The kit is validated for the G5 15 (5587) and G7 15 (7588) as a matched 16 GB pair. Installing both sticks together gives the rated 2666 MT/s at CL19 without mixing speeds.

How can I confirm the memory is running at 2666 MHz CL19 after installation?

Open Task Manager or a tool like CPU-Z and check the speed and timing readouts; they should show 2666 MT/s and 19-19-19 latency.

What comes in the box and is anything else required?

Two 8 GB DDR4 260-pin SODIMM modules are included. No extra parts or cables are needed for the supported Dell models.
