Dual-channel 32 GB kit with two 16 GB DDR5 4800 CL40 SODIMM modules at 1.1 V for laptops and all-in-one systems
Capacity 32GB (2 x 16GB)
This OWC kit supplies 32 GB of DDR5 laptop memory in a matched pair of 16 GB modules. It uses the 262-pin SO-DIMM form factor and runs at 4800 MHz with a CL40 latency. The modules operate at 1.1 V and are unbuffered, non-ECC components built to JEDEC standards.
The kit fits laptops, all-in-one desktops and NAS systems that accept DDR5 SO-DIMMs and can use a dual-channel 32 GB configuration. Systems that require registered or ECC memory cannot use these modules. Buyers needing a single module or a different total capacity should select another kit.
The CAS latency of CL40 at the rated 4800 MHz speed is the key timing figure that determines whether this kit matches the memory controller requirements of a specific platform.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Yes, each module uses the standard 262-pin DDR5 SO-DIMM form factor found in current laptops and all-in-one systems.
Align the off-centre notch on the module with the slot key, press firmly until the side clips click, and verify both 16 GB sticks are fully seated for dual-channel operation.
No, the modules are non-volatile DRAM with no onboard battery or firmware; they operate at 1.1 V and only need occasional dust removal from the contacts.
