OWC
A 64 GB dual-channel DDR5 5600 CL46 kit of two 32 GB 262-pin SODIMMs at 1.1 V for laptops and all-in-one systems
Capacity 64GB (2 x 32GB)
This OWC kit delivers 64GB of DDR5 memory across two 32GB modules built to the PC5-44800 5600MHz standard. It uses the 262-pin SO-DIMM form factor and runs at the JEDEC-defined 1.1V, making it a direct drop-in for compatible notebooks, all-in-one desktops and supported NAS appliances.
Builders whose systems accept dual-channel DDR5 SO-DIMMs and can address 64GB will gain the full benefit. Buyers whose hardware is limited to lower memory generations, smaller maximum capacities or single-channel layouts should look at different modules.
Each stick operates at DDR5 5600 with a CAS latency of CL46 and a 2Rx8 organisation, conforming to the PC5-44800 standard. If the target device requires a different speed grade, latency or voltage, this kit will not work.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
These modules use the standard 262-pin DDR5 SO-DIMM form factor required by compatible laptops and all-in-one systems.
Insert each 32GB stick at an angle into the slot, then press down firmly until the side retention clips click audibly into place.
DDR5 memory has no scheduled replacement interval; swap modules only if diagnostics report errors or system instability occurs.
