CORSAIR Vengeance CMSX16GX4M2A2666C18 is a 16GB laptop memory kit with two 8GB DDR4-2666 SO-DIMMs, suited to compatible laptops that support this memory type and speed.
Recommended For
- Owners of a compatible, upgradeable DDR4 laptop who want to replace a smaller memory kit with 16GB for everyday multitasking, such as keeping multiple browser tabs and work apps open. Confirm the laptop supports 260-pin DDR4 SO-DIMMs and the kit’s speed.
- Laptop users with two compatible SO-DIMM slots who want a matched 2×8GB kit. Using both modules can enable dual-channel operation on supported systems; Tom’s Hardware notes that dual-channel memory can improve performance compared with a single module.
- Owners of a compatible DDR4 small-form-factor PC or Intel NUC who need laptop-style SO-DIMM memory. CORSAIR lists compatible small-form-factor PCs and Intel NUC kits among the product’s intended systems.
- Owners of older Intel Core i5 or i7 notebooks whose device specifications call for compatible DDR4 SO-DIMMs and can use 16GB total. CORSAIR specifically lists 6th- and 7th-generation Intel Core i5 and i7 notebooks in the kit’s compatibility details.
