Speed DDR5 5200 (PC5 41600)

CAS Latency CL42

  • 64 GB capacity handles heavy multitasking with four 16 GB modules
  • DDR5 5200 MHz speed moves data faster for responsive workloads
  • CL42 latency keeps timing tight at standard 1.1 V operation
  • 262-pin SO-DIMM form factor fits compatible laptop and AIO slots
  • Non-ECC unbuffered design suits mainstream consumer platforms

64GB DDR5 SO-DIMM Kit for Laptops

This A-Tech kit delivers 64GB of DDR5 memory across four 16GB modules. It targets owners of compatible laptops, notebooks, and all-in-one PCs who need maximum capacity for heavy multitasking, content creation, or virtualization workloads. The modules run at the standard 1.10V voltage.

Quad-Channel 262-Pin DDR5-5200 Integration

The kit uses the 262-pin SO-DIMM form factor required by DDR5 laptop platforms. Four unbuffered, non-ECC modules populate four slots to enable quad-channel operation where the platform supports it. Builders must confirm their system accepts DDR5-5200 SO-DIMMs and has four available slots before installation.

Sustained CL42 Operation at Standard Voltage

Rated at 5200MHz with CL42 timings, the memory maintains its specified latency and frequency under continuous load without elevated voltage. Major-brand DRAM ICs and factory testing support stable throughput during extended rendering, compilation, or database sessions. No heat spreader is fitted, so chassis airflow manages module temperature.

Questions about this item

What is the CAS latency of these DDR5 5200MHz modules under sustained load?

The kit runs at CL42 latency, which is the primary timing figure for these 5200MHz DDR5 SO-DIMMs.

How much heat does a 64GB quad-channel kit produce when running all day?

These modules operate at the standard 1.1V DDR5 voltage and have no heat spreaders, so thermal output is low for typical laptop workloads.

Which DDR5 SO-DIMM slots must my laptop have to install this 4x16GB kit?

Your system needs four 262-pin DDR5 SO-DIMM slots and must support quad-channel memory at 5200MHz.
