OWC 16GB DDR3 1866 CL13 204-pin 1.5V SODIMM laptop RAM

SKU CH-BK40-FSYXA

Single 16 GB DDR3 1866 CL13 204-pin SODIMM at 1.5 V for laptops, mini PCs and NAS systems

  • Total capacity16 GB
  • Rated speedDDR3 1866 (PC3 14900)
  • CAS latencyCL13
  • Rated voltage1.5 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems

Capacity 16GB

  • 16 GB single-module upgrade doubles laptop memory capacity
  • DDR3 1866 CL13 speed accelerates multitasking and large-file workflows
  • JEDEC-standard 1.5 V design ensures warranty-safe compatibility
  • 204-pin SODIMM form factor fits laptops, mini PCs and NAS systems
  • Unbuffered non-ECC architecture simplifies DIY installation

Single-module 16 GB upgrade

This 204-pin DDR3 SODIMM delivers 16 GB in a single stick, running at 1866 MT/s with CL13 latency at 1.5 V. It targets laptops, all-in-one PCs and NAS units that accept non-ECC, unbuffered memory. Buyers needing more than 16 GB per slot or registered ECC modules should look elsewhere.

Sustained throughput on DDR3 platforms

At 1866 MT/s the module moves data at the PC3-14900 rate continuously, not just in short bursts. CL13 timing keeps latency predictable during long compile jobs or extended file-serving sessions. Systems limited to lower DDR3 speeds will clock the module down automatically.

JEDEC-compliant green PCB

The stick uses a standard-height green PCB without a heat spreader, fitting tight SODIMM sockets in thin laptops and mini PCs. Gold-edge contacts meet JEDEC and RoHS requirements for reliable insertion cycles. No extra clearance or cooling hardware is needed for daily operation.

Questions about this item

How much power does this 1.5V DDR3 module draw during continuous operation?

The module runs at the standard JEDEC 1.5 V DDR3 voltage, so power consumption stays within the normal range for DDR3 1866 CL13 SODIMMs.

My laptop only has one free 204-pin SO-DIMM slot — is that enough for this 16 GB stick?

Yes, the upgrade consists of a single 16 GB 204-pin DDR3 SO-DIMM, so one empty slot is all that is required.

Can I pair this CL13 1866 MHz stick with slower DDR3 modules already in my system?

The module is JEDEC-compliant and will down-clock to match the speed and timings of any slower DDR3 memory already installed.
