OWC 32GB (2x16GB) DDR4 2133MHz CL15 ECC SODIMM 1.2V 260-pin laptop RAM

SKU CH-WHJZ-M5NFH

A dual-channel 32 GB kit of two 16 GB DDR4 2133 MHz CL15 ECC SODIMM modules at 1.2 V for laptops and NAS systems

  • Capacity32GB (2 x 16GB)
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.2V
  • ECCYes

Capacity 32GB (2 x 16GB)

  • Dual-channel 32 GB kit expands multitasking headroom with two 16 GB modules
  • ECC protection detects and corrects single-bit errors for data integrity in NAS and micro-servers
  • JEDEC-standard DDR4 2133 MHz CL15 timing ensures broad laptop and all-in-one compatibility
  • Low 1.2 V operation reduces power draw and heat in compact systems
  • Unbuffered 260-pin SO-DIMM form factor fits standard DDR4 laptop slots directly

32GB DDR4 ECC SODIMM Kit

This dual-channel kit delivers 32 gigabytes of DDR4 2133MHz memory using two 16GB modules. ECC error correction and unbuffered operation suit laptops, all-in-one PCs and NAS units that require data integrity. CL15 latency and 1.2V voltage follow JEDEC standards for broad compatibility.

DDR4 2133MHz Interface Limits

The DDR4 2133MHz interface caps transfer rates at PC4-17000 bandwidth, so systems that support faster DDR4 speeds will run these modules at the lower frequency. ECC function only activates on platforms with a compatible memory controller; consumer laptops without ECC support will ignore the feature.

Upgrading from Lower-Capacity Non-ECC RAM

Replacing a smaller non-ECC kit with this 32GB ECC set adds capacity for larger workloads and enables error correction where the hardware allows. The jump is worthwhile when the system supports ECC and needs more than 16GB total memory; it adds no benefit on platforms limited to 16GB or lacking ECC capability.

Questions about this item

Should I choose the 32GB dual-channel kit or a single 16GB module?

The kit provides 32GB total across two 16GB modules, enabling dual-channel bandwidth on compatible laptops, all-in-one systems or NAS units. A single module would run in single-channel mode and halve the peak throughput.

What does the 2133MHz CL15 rating mean for real-world responsiveness?

At 2133MHz with CAS latency 15 the modules deliver PC4-17000 transfer rates, so multitasking, large file handling and simultaneous applications run smoother than with slower or higher-latency memory.

Does the 260-pin DDR4 SO-DIMM interface limit the speed on my system?

The 260-pin DDR4 SO-DIMM form factor caps operation at the JEDEC-standard 2133MHz; the memory controller will not exceed this frequency even if the platform supports higher DDR4 speeds.
