Capacity and Kit Layout

This kit supplies 64GB of desktop memory across four 16GB DDR4 modules. It is built for users who need extra headroom for multitasking, content creation or virtual machines on a standard PC platform.

Compatibility Checks

Verify that your motherboard accepts 288-pin unbuffered non-ECC DDR4 DIMMs and can run at 1.2V. The modules are backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so they will clock down if the board does not support the rated 3200MHz frequency.

Sustained Load Behaviour

Under continuous workloads the memory operates at the JEDEC-standard CL22 latency and 1.2V without a heat spreader. Thermal performance therefore depends on case airflow, and the modules will maintain their rated speed as long as the system cooling keeps temperatures within specification.

Questions about this item

What comes in the box with the OWC 64GB kit and do I need anything else to install it?

The kit contains four 16GB DDR4 3200MHz UDIMM modules. No extra parts are required; they plug directly into standard 288-pin desktop DIMM slots.

Should I choose this 64GB four-module kit or a smaller capacity for my desktop?

Pick this 64GB kit if your motherboard has four slots and you want the full capacity at 3200MHz CL22. Smaller kits leave slots free but give less total memory.

What does the 3200MHz CL22 rating mean once the RAM is running in my PC?

The modules operate at 3200MHz with CAS latency 22 at 1.2V. They also down-clock automatically to 2933MHz, 2666MHz, 2400MHz or 2133MHz if the platform requires it.
