Laptop DDR5 32GB module

This 32GB DDR5 SO-DIMM is built for laptop, notebook and all-in-one systems that accept 262-pin memory. It replaces the Hynix HMCG88AGBSA module and operates at the standard 1.10V DDR5 voltage. The unbuffered, non-ECC design suits mainstream mobile platforms.

CL40 latency at 5600MHz

The module runs at DDR5 5600 (PC5-44800) with a CAS latency of CL40. This timing figure is the primary spec that determines whether the stick matches your system's supported memory profile. Verify the laptop's qualified vendor list before purchase.

Steady throughput without a spreader

Without a heat spreader the module relies on the chassis airflow to maintain its 5600MHz data rate during extended workloads. Sustained multitasking and large dataset handling remain stable as long as the system cooling keeps the SO-DIMM within its thermal limits.

Questions about this item

What does the DDR5 5600 CL40 rating mean for real-world laptop performance?

The module runs at DDR5 5600 with CL40 latency, giving your laptop a high-speed memory path that reduces load times and improves responsiveness during multitasking

How does the PC5-44800 designation limit the memory speed in practice?

PC5-44800 is the peak transfer rate specification for DDR5 5600, so the module will not exceed this bandwidth even if the platform supports faster DDR5 speeds

Will this 262-pin SODIMM fit my laptop's memory slot without extra hardware?

Yes, the 262-pin DDR5 SO-DIMM form factor matches standard laptop slots and requires no heat spreader or additional mounting hardware
