DDR5 laptop memory kit with two 32 GB SO-DIMM modules running at 4800 MHz CL40

  • 64 GB total capacity for demanding multitasking
  • Dual 32 GB modules enable dual-channel bandwidth
  • DDR5 4800 MT/s speed accelerates data throughput
  • CL40 latency supports responsive system performance
  • SO-DIMM form factor fits standard laptop slots

Kit contents and purpose

This kit supplies two 32 GB SO-DIMM modules for a total of 64 GB of DDR5 laptop memory. It is intended for owners of compatible notebooks who need the maximum capacity their board allows. Buyers whose systems only accept a single module or a lower density per slot cannot use this kit.

Installation notes

Each module installs by aligning the notch with the slot and pressing down until the side clips engage. The most common issue is a slot that does not support 32 GB density, which prevents the system from posting. Verify the motherboard specification before opening the package.

Deciding specification

The kit runs at 4800 MT/s with a CAS latency of 40 and uses GDDR5 SDRAM chips in SO-DIMM form factor. If your laptop requires a different speed, latency or memory type, this kit will not be compatible.
