Overview
Crucial makes this kit of two laptop-format SODIMM modules for DDR5 notebooks. The modules run at the rated speed or at two lower settings, and the description cites XMP and EXPO profile support.
Doubling a laptop's memory helps multitasking, editing and gaming where the board allows it. Latency numbers conflict between the listing fields, and the description's profile claims fit laptops only if the firmware exposes them.
Who it's for
An upgrader with a recent Intel or AMD laptop that takes DDR5 SODIMM modules. Desktop owners need full-size modules, and older laptops need a different memory generation.
Pros and cons
- Matched pair for dual channel
- Steps down to slower speeds
- Compact laptop format
- Lifetime limited warranty
- Latency listed two ways
- Laptop must support DDR5 SODIMM
- Profile support may depend on firmware
- Tested laptop list not given
Performance notes
The speed a laptop reaches is decided by the processor and board, and the modules fall back to the highest supported setting. Two modules in the two slots enable dual channel for more bandwidth. Lower voltage than earlier memory generations reduces power draw.
