Manufacturer description

The Crucial 32GB DDR5 SODIMM (CT32G48C40S5) is a single-module laptop memory upgrade built on Micron silicon, running at 4800MHz with CL40 timings on a 1.1V, 262-pin SODIMM in a 2Rx8 non-ECC configuration rated PC5-38400. If your notebook shipped with 8GB or 16GB and stutters when you keep 40 browser tabs, a Docker stack, and a 4K timeline open at once, this Crucial DDR5 module gives you the headroom to stop closing apps to finish a task. It is tuned for 12th Gen Intel Core and AMD Ryzen 7000 Series laptops, and supports both Intel XMP 3.0 and AMD EXPO profiles on the same stick, so one part…

Frequently Asked Questions

Will this work in my laptop?

It is a 262-pin DDR5 SODIMM specified for 12th Gen Intel Core and AMD Ryzen 7000 Series laptops. It will not fit DDR4 or desktop DIMM slots. Confirm your laptop uses DDR5 SODIMMs and is not soldered-memory-only before ordering.

Is this one 32GB stick or a 2x16GB kit?

Part number CT32G48C40S5 is a single 32GB module. If you want dual-channel from two matched sticks, you need two of them.

What speed and latency does it run at?

4800MHz with CL40 timings, rated PC5-38400 at 1.1V, in a 2Rx8 non-ECC configuration. Your laptop will run it at 4800MHz only if its CPU and BIOS support that speed; otherwise it downclocks.

Does it support ECC?

No. This module is non-ECC. If your workstation requires ECC memory, this is not the right part.

What warranty does Crucial provide?

Crucial memory is typically covered by a long-term warranty, but terms vary by region and retailer. Check the current product listing and Crucial's warranty page for the terms that apply to your purchase.
