OWC 16GB DDR4 2400 CL17 288-pin desktop RAM

SKU CH-J686-ST0GV

A 16GB DDR4 2400 CL17 UDIMM module for desktop PCs, workstations and NAS systems

  • Capacity16GB
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.2V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 16GB

  • 16 GB capacity lets you run more apps simultaneously
  • DDR4 2400 MHz CL17 speed boosts system responsiveness
  • 2 V low voltage reduces power draw and heat
  • 288-pin unbuffered UDIMM fits standard desktop slots
  • Backward compatible with 2133 MHz systems for easy upgrades

Single-module 16 GB desktop upgrade

This single 16 GB DDR4 module runs at 2400 MHz with CL17 latency and 1.2 V operation. It fits any desktop, workstation or NAS system that accepts 288-pin unbuffered non-ECC DIMMs and is backward compatible with 2133 MHz platforms.

Thermals power and acoustic profile

The module has no heat spreader and operates at standard JEDEC voltage, so it adds minimal heat and draws no extra power beyond the 1.2 V specification. Passive cooling means zero fan noise from the memory itself under normal workloads.

Compliance testing and support program

Every stick is validated in OWC's in-house lab for full JEDEC and RoHS compliance, ensuring a warranty-safe upgrade. The advanced replacement program and lifetime limited warranty with free technical support back the module after installation.

Questions about this item

Will this module work in a system that currently runs DDR4 2133 memory?

Yes, it is backward compatible with 2133 MHz DDR4 systems and will run at the lower speed automatically.

Does this stick require ECC support from the motherboard?

No, it is a non-ECC unbuffered DIMM, so it works in standard desktop boards without ECC capability.

What voltage does the module operate at?

It runs at the standard DDR4 voltage of 1.2 V, matching the JEDEC specification for DDR4 memory.
