64GB DDR5 SO-DIMM for laptops

This 64GB G.SKILL Ripjaws module uses 262-pin DDR5 technology at 5600 MT/s with CL46 timing. It targets users upgrading recent laptops or small-form-factor PCs that accept a single high-capacity stick. The 1.10V operating voltage matches standard DDR5 specifications for mobile platforms.

Sustained load behaviour

Hand-screened IC chips and the 46-45-45-89 timing table are designed to maintain rated frequency during extended workloads. The module delivers faster data transfer and higher energy efficiency than standard DDR4 memory without requiring manual tuning. Unbuffered, non-ECC operation keeps latency predictable for gaming and content-creation sessions.

Installation notes

Plug-and-play support allows the SO-DIMM to configure at 5600 MT/s automatically on compatible AMD and Intel platforms. Builders must verify that their laptop or SFF board accepts a 64GB single-rank module and provides a 262-pin DDR5 slot. Systems limited to lower maximum capacities or DDR4-only slots cannot use this kit.

Questions about this item

How much heat and power does the 1.10V 64GB module draw when the laptop runs all day?

It operates at 1.10V, the standard DDR5 voltage, so power draw and heat stay low during continuous use.

What must my laptop already have to accept this 262-Pin DDR5 SO-DIMM?

A DDR5-compatible SO-DIMM slot and a CPU or chipset that supports DDR5 5600 memory.

Will this CL46 DDR5 stick work alongside older DDR4 modules I might keep?

No, DDR5 and DDR4 use different pin layouts and voltages, so they cannot be mixed in the same system.
