8GB DDR4 2666MHz SODIMM upgrade

This 8GB DDR4 2666MHz SO-DIMM is built for Dell G5 15 5587 Gaming, G7 15 7588 Gaming and Inspiron 27 7777 systems. It runs at 1.2V with CL19 timing and uses a 260-pin unbuffered layout. The module is a single 1Rx8 stick from Computer Memory Solutions.

Suits single-slot expansion.

Buyers adding memory to the listed Dell models will find guaranteed compatibility and a lifetime exchange warranty. The non-ECC, unbuffered design fits consumer laptop and all-in-one slots. Systems requiring ECC, registered modules or speeds above 2666MHz should look elsewhere.

8GB capacity; two-slot ceiling at 32GB

Each supported platform accepts two SO-DIMMs for a maximum of 32GB. One module delivers 8GB of headroom for everyday multitasking and gaming. Installing a second identical stick reaches the platform limit; larger single modules or four-slot configurations are not supported by these systems.

Questions about this item

Does this 260-pin SODIMM fit the two slots in a Dell G5 15 5587?

Yes, the module is a 260-pin DDR4 SO-DIMM and the Dell G5 15 5587 uses two SODIMM slots supporting up to 32 GB total.

Will this CL19 2666 MHz stick run at its rated speed next to an existing CL19 2666 MHz module?

When paired with another DDR4 2666 CL19 module the system will operate in dual-channel at 2666 MHz with 19-19-19 timings at 1.2 V.

How can I confirm the stick is detected at 2666 MHz after installation?

Open Task Manager Performance tab or run CPU-Z; the memory section should show 2666 MHz, 8 GB, and 1Rx8 organisation.
