A-Tech 16GB DDR5 5600MHz CL40 262-Pin SODIMM Laptop RAM

DDR5 5600 MHz SODIMM for Laptop Upgrades

This A-Tech module delivers 16 GB of DDR5 memory at 5600 MHz with CL40 latency and 1.10 V operation. It uses the standard 262-pin SO-DIMM form factor and is unbuffered non-ECC. The stick is designed as a direct replacement for Hynix HMCG78AGBSA, HMCG78AGBSA092N and HMCG78AGBSA095N modules in laptops, notebooks and all-in-one PCs.

Replaces Specific Hynix DDR5 Part Numbers

The module matches the exact specifications of the three listed Hynix part numbers, so it fits the same slots and runs at the same 5600 MHz speed without configuration changes. The upgrade is worthwhile when your system currently has less than 16 GB or runs slower DDR5, and the motherboard supports this frequency and voltage. Buyers who need ECC, registered memory or a different pin count cannot use this module.

Sustained Load Behaviour at Standard Voltage

Running at the DDR5 standard 1.10 V, the memory maintains its rated 5600 MHz throughput during extended workloads such as large compiles, video exports or virtual-machine clusters. The absence of a heat spreader means thermal performance depends on the chassis airflow, but the low voltage helps keep temperatures manageable. Systems that throttle memory speed under prolonged stress will not see the full benefit.
