OWC 32GB (4x8GB) DDR4 2933MHz CL21 ECC SODIMM laptop RAM

SKU CH-DSE7-A6423

32 GB kit of four 8 GB DDR4 2933 MHz ECC SODIMMs at CL21 and 1.2 V for laptops, NAS and micro servers

  • Total capacity32 GB (4 × 8 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Kit configurationDual Channel Kit

Capacity 32GB (4 x 8GB)

  • 32GB kit lets you run more apps and larger files simultaneously
  • 2933MHz DDR4 speed accelerates data throughput for responsive multitasking
  • ECC protection detects and corrects single-bit errors to keep workloads stable
  • 2V low voltage reduces power draw and heat in laptops and NAS units
  • Backward compatible with 2666, 2400 and 2133MHz systems for flexible upgrades

Capacity and Use Cases

This 32GB kit contains four 8GB DDR4 SODIMM modules rated at 2933MHz with CL21 latency. It targets laptops, all-in-one PCs, NAS units and micro servers that require ECC protection for data integrity. The unbuffered design fits standard 260-pin slots and operates at 1.2V.

Speed Limits and Compatibility

The modules run at PC4-23400 2933MHz but will down-clock automatically to 2666MHz, 2400MHz or 2133MHz when the host platform does not support the higher frequency. JEDEC compliance ensures the kit meets the baseline electrical and timing specifications for DDR4 SODIMM sockets.

Upgrade Path and Value

The kit replaces lower-capacity or non-ECC memory in systems that support 260-pin DDR4 SO-DIMMs and can address 32GB across four slots. The jump is worthwhile when workloads demand error correction or when the current installation cannot hold the required dataset.

Questions about this item

Should I choose the 32GB kit or a smaller capacity?

The kit provides 32GB total using four 8GB modules. Select it if your laptop or NAS supports four SO-DIMM slots and you need the full capacity for multitasking or large datasets.

What does the 2933MHz rating mean once installed?

The modules run at 2933MHz CL21 when the system supports that speed. If the platform only supports 2666MHz, 2400MHz or 2133MHz, the memory will downclock automatically to match.

Is the 260-pin DDR4 interface compatible with my laptop?

The modules use the standard 260-pin DDR4 SO-DIMM form factor at 1.2V. They fit any laptop, all-in-one or NAS slot designed for DDR4 SO-DIMM memory.
