Dell G7 17 and Inspiron 2-in-1 Upgrade

This 16 GB DDR4 SO-DIMM is built for the Dell Gaming G7 17 (7790), Inspiron 14 (5491) 2-in-1 and Inspiron 15 (5591) 2-in-1. It delivers a single 16 GB module that slots straight into the 260-pin socket. The kit targets owners of those specific laptops who need more memory without guessing compatibility.

Capacity Headroom and Limits

The module provides 16 GB in one stick and the platforms support a maximum of 32 GB across two sockets. Adding this stick leaves the second socket free for a matching 16 GB module to reach the ceiling. A 64-bit operating system is required to address more than 4 GB. All installed memory will run at the speed of the slowest module or the processor limit.

Unbuffered 260-Pin Build

The stick uses an unbuffered, non-ECC design with 2Rx8 organisation and operates at 1.2 V. No heat spreader is fitted, keeping the profile low for thin chassis. The 260-pin edge connector matches the factory SO-DIMM slot exactly. Computer Memory Solutions warrants the module against manufacturing defects for the lifetime of the original purchase.

Questions sur cet article

Will the 2666 MHz CL19 DDR4 SODIMM run at its rated speed alongside an existing slower DDR4 module in my Dell G7 17 (7790)?

All installed memory runs at the speed of the slowest module or the CPU limit, so the new stick will downclock to match the existing one.

How can I verify the CM2048642666SO is detected at 16 GB and 2666 MHz after installation?

Check Task Manager’s Performance tab or run CPU-Z; both show capacity, speed, and CAS latency for each slot.

Does the package include only the single 16 GB DDR4 SODIMM, or are tools and a second module also supplied?

The box contains one 260-pin DDR4 SODIMM; no tools, screws, or additional modules are included.
