128GB DDR4 3200MHz Kit

This OWC desktop memory kit supplies 128GB across eight 16GB unbuffered UDIMMs. Each module runs at 3200MHz with a CL22 latency and 1.2V operation. The kit is designed for standard 288-pin desktop slots and meets JEDEC specifications.

Workstations and NAS builds needing high capacity

The 128GB total suits content creation, virtualization and network-attached storage systems that benefit from large memory pools. Systems limited to lower maximum memory per slot or requiring ECC registered modules should consider alternative configurations.

Sustained load behaviour at rated speed

Under continuous workloads the modules maintain their 3200MHz data rate and CL22 timing at the standard 1.2V. Backward compatibility allows operation at 2133, 2400, 2666 or 2933MHz when the platform dictates a lower frequency.

Highlights

  • 2 V operation reduces power draw and heat output
  • JEDEC and RoHS compliant for warranty-safe upgrades

Questions about this item

Will this 128 GB kit work in a desktop that currently runs 2666 MHz memory?

Yes, the modules are backward compatible with 2133, 2400, 2666 and 2933 MHz systems and will run at the highest speed the board supports.

Does the motherboard need to support ECC or registered DIMMs for this upgrade?

No, these are non-ECC unbuffered UDIMMs, the standard type used in most consumer desktops and workstations.

How many physical slots are required to install the full 128 GB?

Eight 288-pin DIMM slots are needed, one for each 16 GB module in the kit.
