A-Tech 64GB DDR5 5600MHz laptop RAM 262-pin CL40 1.1V

Capacity and fit

This single 64 GB DDR5 SO-DIMM uses the 262-pin layout required by current laptop memory slots. It targets owners of compatible notebooks or all-in-one systems who need the maximum single-module capacity available in this form factor.

Speed and voltage limits

The module runs at 5600 MHz with a CAS latency of 40 and operates at the standard 1.1 V DDR5 voltage. Systems that lock memory to lower JEDEC speeds will not reach the rated frequency, and the fixed SPD profile does not support manual timing adjustments.

Unbuffered design and daily handling

Major-brand DRAM ICs are mounted on a bare green PCB without a heat spreader, keeping the profile low enough for thin chassis. The non-ECC unbuffered layout means error correction is absent, so workloads that demand data integrity must rely on software-level checks instead.
