64 GB DDR5 SODIMM kit

This OWC kit provides 64 GB of DDR5 memory across four 16 GB SODIMM modules rated at 5600 MT/s with CL46 latency. It is built for laptops, all-in-one PCs and compatible NAS units that accept 262-pin DDR5 SO-DIMMs. The unbuffered, non-ECC design suits mainstream mobile platforms.

Check your system before ordering

Verify that your device supports DDR5 SO-DIMMs at 1.1 V and has four available slots for a quad-channel population. Confirm the motherboard or firmware can address 64 GB total capacity and that the BIOS recognises JEDEC-standard PC5-44800 modules. Some thin-and-light laptops solder memory or limit slot count, so consult the service manual first.

Sustained-load behaviour

JEDEC-compliant 5600 MT/s operation delivers stable throughput during extended multitasking, large-file editing or NAS workloads without relying on overclock profiles. The CL46 timing and 1.1 V voltage keep power draw predictable under continuous use. Modules lack heat spreaders, so adequate chassis airflow is required to maintain rated speeds during prolonged sessions.

Questions about this item

Does the kit include four 16 GB DDR5 SODIMM modules or do I need to buy them separately?

The package contains four 16 GB DDR5 5600 CL46 SODIMM modules for a total of 64 GB, so no additional memory sticks are required.

Should I choose this 64 GB DDR5 5600 CL46 kit or a different capacity for my laptop?

Select this 64 GB kit when your laptop supports four SODIMM slots and you want the maximum 64 GB at 5600 MT/s with CL46 timing.

What does the 5600 MT/s speed mean once the modules are installed in my system?

The memory will run at 5600 MT/s (PC5-44800) with CL46 latency at 1.1 V, delivering the rated bandwidth and timing your platform negotiates.
