Capacity 64GB (8 x 8GB)

  • 64 GB capacity lets you run many apps and large files at once
  • Eight 8 GB modules populate four dual-channel slots for balanced bandwidth
  • DDR4 2133 CL15 timing delivers responsive performance at standard JEDEC speed
  • 2 V operation reduces power draw and heat in laptops and NAS units
  • ECC unbuffered design detects and corrects single-bit errors for data integrity

64 GB DDR4 ECC SODIMM kit

This OWC kit delivers 64 GB of DDR4 ECC memory in eight 8 GB modules. Each stick runs at 2133 MHz with CL15 latency and operates at 1.2 V. The unbuffered design targets laptops, all-in-one PCs and NAS appliances that require error-correcting code support.

260-pin SO-DIMM form factor

Modules fit standard 260-pin DDR4 SO-DIMM slots and run without additional cooling. The dual-channel kit layout allows population of matched pairs for maximum throughput. No heat spreader is included, so clearance inside compact chassis remains unaffected.

Builders needing ECC reliability

The kit suits users who need data integrity in micro servers, NAS boxes or workstation-class laptops. Systems limited to non-ECC memory or to speeds above 2133 MHz cannot use these modules. Buyers requiring higher frequencies or lower latencies should consider alternative memory.

Questions about this item

What speed and latency will limit sustained throughput on this DDR4 2133 CL15 kit?

The modules run at 2133 MT/s with a CAS latency of 15, so the peak bandwidth is capped at PC4-17000 and latency-bound workloads will see CL15 timing.

How much heat and power does the 8-module kit draw when running continuously?

Each 8 GB module operates at 1.2 V without a heat spreader; total power scales with all eight sticks installed, and the unbuffered ECC design keeps per-module draw low.

Which slot type must the laptop or NAS already provide for these 260-pin SO-DIMMs?

The system needs eight DDR4 260-pin SO-DIMM slots; the kit will not fit any other pin count or DDR generation.
