OWC 4GB DDR3 1600 PC3-12800 CL11 1Rx8 204-pin 1.5V Non-ECC SODIMM laptop RAM

SKU CH-K1Y5-AE3D9

A 4 GB DDR3 1600 SODIMM module for upgrading laptop, mini PC or NAS system memory

  • Capacity4GB
  • Type204-Pin DDR3 SO-DIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCNo

Capacity 4GB

  • Boost responsiveness with 1600 MHz DDR3 speed
  • Expand multitasking headroom using 4 GB capacity
  • Drop-in fit for laptops via 204-pin SO-DIMM
  • JEDEC-compliant 1.5 V operation ensures broad compatibility
  • Simple DIY upgrade with unbuffered non-ECC design

Compatible upgrade for laptops and NAS

This module is a 4 GB DDR3 1600 SO-DIMM built to JEDEC standard timings of CL11 at 1.5 V. It targets owners of laptops, all-in-one PCs or NAS units that accept 204-pin unbuffered non-ECC memory and need a straightforward capacity increase.

Suits single-slot upgrades or matching pairs

The stick works for users adding one module to a free slot or installing a matched pair in a two-slot system. Builders whose platforms require registered or ECC memory, or those needing more than 4 GB per slot, should look at other configurations.

Runs at DDR3 1600 PC3-12800 CL11

The decisive specification is the 1600 MT/s data rate with CL11 latency at the standard 1.5 V operating voltage. If the host system specifies this exact speed and timing the module will operate at its rated settings.

Questions about this item

Is the 4 GB DDR3 1600 CL11 module the right capacity for a single-slot upgrade?

Yes, the single 4 GB stick matches the 204-pin SO-DIMM form factor and 1.5 V JEDEC standard used in many laptops, mini PCs and NAS systems.

What real-world speed will I see from the PC3-12800 rating once installed?

The module runs at 1600 MHz with CL11 latency, delivering the standard DDR3-1600 bandwidth your platform negotiates at boot.

Does the 204-pin DDR3 SO-DIMM interface limit the maximum transfer rate?

The 204-pin DDR3 SO-DIMM connector is defined for DDR3-1600 (PC3-12800), so the module operates at its rated 1600 MHz without interface bottleneck.
