Capacity 32GB (2 x 16GB)

  • 32 GB dual-channel kit doubles capacity for multitasking workloads
  • ECC protection detects and corrects single-bit errors in critical data
  • 2666 MHz DDR4 speed with CL19 latency supports responsive system operation
  • 2 V low-voltage modules reduce power draw and heat output
  • JEDEC-compliant unbuffered UDIMM fits workstations, servers and NAS systems

Capacity and kit

This OWC kit provides 32GB of DDR4 desktop memory in a matched pair of 16GB modules. It is built for workstations, servers and NAS systems that require error-correcting code.

ECC unbuffered operation

The single specification that decides fit is the ECC unbuffered design. Only platforms that accept 288-pin UDIMMs with ECC will recognise and use the error-correction capability.

Headroom and limits

Two 16GB sticks fill two slots and leave additional slots open for future expansion on boards with four or more DIMM sockets. The modules run at 2666MHz CL19 and will downclock to 2133MHz or 2400MHz when the system requires it.

Questions about this item

What does the 2666 speed rating mean once the modules are installed in a real machine?

The DDR4 2666 rating means each module runs at 2666 MT/s; the system will operate them at the highest speed the CPU and motherboard support, which may be 2666, 2400 or 2133 MT/s

What does the PC4-21300 label tell me about the interface and its practical limit?

PC4-21300 is the JEDEC designation for DDR4 2666; it defines the standard timing and voltage envelope the memory controller must meet

What physical slot and clearance do these 288-pin UDIMMs need to fit and mount?

They require standard 288-pin DDR4 UDIMM slots; with no heat spreader the modules are low-profile and clear most CPU coolers
