32GB DDR5 SO-DIMM Kit

This Corsair Vengeance kit provides 32 GB of DDR5 laptop memory in a matched pair of 16 GB modules. Each module uses the 262-pin SO-DIMM form factor and operates at 4800 MT/s with a CAS latency of 40. The kit runs at 1.10 V and is designed for compatible Intel and AMD laptops, small-form-factor PCs and Intel NUC kits.

Suits DDR5 laptops and NUCs

The kit targets owners of DDR5-capable gaming or performance laptops who want a straightforward capacity upgrade without BIOS changes. XMP 3.0 compatibility allows higher frequencies on supported Intel platforms. Builders whose systems require a different memory generation, pin count or voltage should look at other options.

4800 MT/s DDR5 speed rating

The decisive specification is the DDR5 4800 (PC4 38400) speed rating combined with CL40 40-40-40-77 timings. This determines whether the modules will run at their rated frequency on a given platform. Verify that the laptop or NUC supports DDR5 4800 SO-DIMMs before purchase.

Questions about this item

How can I confirm the Corsair Vengeance DDR5 4800 CL40 modules are running at the correct speed after installation?

Check the memory speed in Windows Task Manager or a tool like CPU-Z; it should report 4800 MT/s. The kit uses 262-pin DDR5 SO-DIMM form factor and operates at 1.10V with 40-40-40-77 timings.

What is included in the box with the CMSX32GX5M2A4800C40 kit and what extra parts are required?

The box contains two 16GB DDR5 SO-DIMM modules for a total of 32GB. No additional components are needed; a small screwdriver is typically the only tool required to access the laptop memory slots.

Which capacity version of the Vengeance DDR5 4800 series should I choose for a laptop with two memory slots?

This 32GB kit (2 x 16GB) fills both slots in a dual-channel laptop. If your system has only one slot or you need less capacity, look for a single 16GB module of the same speed and latency.
