48GB DDR5 5600MHz SODIMM

This is a 48GB DDR5 laptop memory module running at 5600MHz with CL40 latency and 1.1V operation. It uses a 262-pin SO-DIMM form factor and is an unbuffered non-ECC design. The module is built as a compatible replacement for the Hynix HMCGY8MGBSB part number and suits laptops, notebooks, and all-in-one computers that accept DDR5 SO-DIMMs.

DDR5 laptop upgrades only

This module suits owners of DDR5-compatible laptops, notebooks, or all-in-one PCs that support 5600MHz SO-DIMMs and can address a 48GB unbuffered non-ECC stick. Buyers whose systems require ECC or registered memory, or those limited to earlier DDR generations, cannot use this part. Anyone needing a heat spreader should also look elsewhere because this module has none.

Single 48GB DDR5 5600MHz module

The decisive specification is the 48GB capacity delivered in one 262-pin DDR5 SO-DIMM rated at 5600MHz (PC5-44800) with CL40 timing at 1.1V. Your system must support DDR5 SO-DIMMs at this speed and accept a 48GB unbuffered non-ECC module in a single slot for this upgrade to work.

Questions about this item

Does the 48 GB DDR5 5600 MHz module ship with any extra parts or do I need to buy anything else?

The package contains a single 262-pin SODIMM stick; no additional components are required for installation.

How do I decide between the 48 GB 5600 MHz CL40 option and other capacities or speeds?

Choose this 48 GB module when your laptop supports DDR5 5600 and you need the maximum single-stick capacity; select a lower capacity only if your system cannot address 48 GB.

What does the 5600 MHz rating actually deliver once the module is installed in my laptop?

The module runs at the DDR5 5600 standard with CL40 latency at 1.1 V, providing the rated bandwidth and timing your platform negotiates at boot.
