64GB DDR5 SODIMM kit for laptops and all-in-ones

This kit provides 64GB of DDR5 memory in two 32GB modules. It is built for laptops, all-in-one desktops and NAS systems that accept 262-pin SO-DIMMs. The unbuffered, non-ECC design matches mainstream consumer platforms.

4800MHz CL40 at 1.1V JEDEC standard

Each module runs at 4800MHz with a CAS latency of 40 and operates at the standard 1.1V. The dual-rank 2Rx8 organisation and PC5-38400 rating follow the JEDEC specification, ensuring warranty-safe compatibility with qualified systems.

Dual-channel upgrade frees DIMM slots

The matched pair populates both slots for dual-channel bandwidth, leaving no empty sockets for future expansion. Installation is a user-serviceable upgrade on most supported laptops and all-in-ones, and the modules carry OWC's limited lifetime warranty with free technical support.

Questions about this item

What does 4800MHz CL40 mean for my laptop's actual speed?

The kit runs at 4800MHz with a CAS latency of 40, so data transfers at the JEDEC-standard DDR5 rate your CPU's memory controller supports.

Does the PC5-38400 label limit bandwidth on my system?

PC5-38400 is the JEDEC peak transfer rate for DDR5-4800; your laptop's chipset and CPU determine the sustained throughput you will see.

Will the 262-pin modules fit my notebook's SODIMM slots?

Yes — each stick is a standard 262-pin DDR5 SO-DIMM measuring 32GB, designed for laptop and all-in-one memory slots.
