OWC 64GB (8x8GB) DDR4 3200MHz CL22 Desktop RAM

64GB DDR4 3200MHz Kit

This OWC kit supplies 64GB of DDR4 memory across eight 8GB modules running at 3200MHz with CL22 timing. The unbuffered, non-ECC UDIMMs operate at 1.2V and fit standard 288-pin desktop slots. It is intended for desktop PCs, workstations and NAS systems that need a large memory pool for multitasking and large-file workflows.

Upgrade from slower DDR4 speeds

The modules are backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz systems, so they can replace older DDR4 kits without a platform change. The jump is worth it when your current capacity limits the number of open applications or the size of files you can work with simultaneously. JEDEC compliance and ROHS certification make it a warranty-safe upgrade for OEM desktops.

Sustained load behavior

Each module is tested in OWC's in-house lab to meet JEDEC standard specifications at the rated 3200MHz speed. The 1.2V operating voltage keeps power draw consistent during extended sessions. Without a heat spreader, thermal performance depends on case airflow, but the low-voltage DDR4 design helps maintain stable operation under continuous multitasking loads.
