Speed DDR5 4800 (PC4 38400)

CAS Latency CL40

  • 64 GB capacity lets you run heavy workloads and many apps at once
  • DDR5 4800 MHz speed moves data faster for snappier system response
  • CL40 latency keeps timing tight for smooth multitasking
  • 1 V DDR5 voltage cuts power draw compared to 1.2 V DDR4
  • 262-pin SO-DIMM form factor fits DDR5-ready laptops and all-in-ones

64GB DDR5 SODIMM kit

This 64GB kit contains two 32GB DDR5 4800MHz modules built to the 262-pin SODIMM form factor. It targets users upgrading DDR5-compatible laptops, notebooks or all-in-one systems that need more memory for heavy multitasking or large workloads.

Installing DDR5 SODIMM modules

Installation follows the standard SODIMM procedure: power off the machine, open the memory compartment, align the notch on the 262-pin module with the slot key and press firmly until the retention clips engage. The most common issue is a module not fully seated, which prevents the system from posting; re-seating usually resolves it.

Check your system before ordering

Verify that your device supports DDR5 SODIMM memory and accepts a total capacity of 64GB across two slots. Confirm the motherboard or platform can run at 4800MHz CL40 with 1.1V operation. Older DDR4-only systems cannot use these modules because the physical keying and voltage are different.

Questions about this item

How can I confirm the DDR5 4800MHz CL40 kit is running at the correct speed after installation?

Open Task Manager or your system BIOS and verify the memory frequency reads 4800 MT/s with CL40 timings at 1.1V.

What exactly is included in the 64GB kit and what must I purchase separately?

The kit contains two 32GB 262-pin DDR5 SO-DIMM modules; no extra parts or cables are needed for a compatible laptop.

Should I choose this 64GB (2 x 32GB) DDR5 4800 CL40 kit or a different capacity for my upgrade?

Select this kit if your laptop supports DDR5 SO-DIMM and you want the maximum 64GB capacity with standard 1.1V operation.
