Our take on the Crucial SO-DIMM DDR5 5600MHz 16GB (CT16G56C46S5)

This is a single 16GB DDR5 laptop memory module running at 5600 MHz with a standard JEDEC profile. It uses CL46 timings at 1.1V and has no XMP or EXPO profile, so it runs at its rated speed on any laptop that supports DDR5-5600 without BIOS tuning. It suits laptop owners adding or replacing a stick in a DDR5 machine, especially those who want a simple plug-and-play upgrade. Against gaming-branded SO-DIMMs it gives up low-latency profiles and heat spreaders, but it is a safe, widely compatible choice for mainstream laptops.

Pros
  • Runs at 5600 MHz with no XMP or EXPO needed
  • Standard 1.1V DDR5 voltage keeps power draw low
  • Single 16GB stick leaves a slot free for a future upgrade
  • Crucial is a Micron brand with a long record in laptop memory
  • Simple JEDEC timings mean broad laptop compatibility
Cons
  • CL46 timings are looser than low-latency gaming SO-DIMMs
  • No heat spreader, just a bare module
  • No XMP or EXPO, so no headroom beyond 5600 MHz
  • Single module means single-channel until a second stick is added

Questions and answers

Will this work in my laptop?
It fits laptops with a DDR5 SO-DIMM slot that supports 5600 MHz. DDR4-only and soldered-memory laptops cannot use it.
Can I add it alongside my existing RAM?
Yes, if your laptop has a free DDR5 SO-DIMM slot. Matching it with another 16GB DDR5-5600 stick gives dual-channel performance.
Does it need XMP or BIOS settings?
No. It runs at 5600 MHz through its standard JEDEC profile, so no XMP or EXPO setup is required.

It is slower in latency than low-latency gaming kits, but for most laptops the difference is small next to the gain from more capacity.
