  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.2V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 64GB (8 x 8GB)

  • 64 GB total capacity for heavy multitasking
  • DDR4 2133 MT/s speed with CL15 latency
  • 2 V operation reduces system power draw
  • 8 × 8 GB dual-channel kit populates four slots
  • JEDEC compliant and RoHS certified for broad compatibility

Capacity and configuration

This OWC kit provides 64GB of DDR4 memory in an 8×8GB layout. It runs at 2133MHz with a CAS latency of CL15 and operates at 1.2V. The modules are unbuffered, non-ECC UDIMMs with 288-pin connectors and no heat spreaders.

Who this suits

The 64GB capacity suits desktop PCs, workstations and NAS systems that need large memory pools for virtualization, content creation or heavy multitasking. Systems limited to lower maximum capacities, or those requiring ECC or registered DIMMs, should look at a different kit.

Deciding specification

The single specification that decides fit is the 2133MHz DDR4 speed with CL15 timing at 1.2V on 288-pin unbuffered DIMMs; the motherboard must support this exact speed, voltage and form factor.

Questions about this item

Will these 288-pin UDIMMs fit a standard desktop motherboard that takes DDR4 memory?

Yes. Each module is a 288-pin unbuffered DDR4 DIMM, the form factor used by virtually all consumer desktop boards that support DDR4.

My system only has four DIMM slots — can I still use this 64 GB kit?

The kit contains eight 8 GB modules, so you would need eight slots to install the full set. With four slots you can only fit half the capacity.

Is this memory compatible with a NAS that requires non-ECC DDR4 at 1.2 V?

The modules are non-ECC, run at 1.2 V, and are rated for desktop PC and workstation NAS systems, matching those requirements.
