OWC

OWC 4GB DDR3 1333 PC3-10600 CL9 204-pin SODIMM laptop RAM

SKU CH-5Z8W-7VXK5

A 4 GB DDR3 SODIMM running at 1333 MHz with CL9 latency and 1.5 V operation for laptop, mini PC or NAS upgrades

  • Capacity4GB
  • Type204-Pin DDR3 SO-DIMM
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL9
  • Voltage1.5V
  • ECCNo

Capacity 4GB

  • Boost system responsiveness with a 4GB DDR3 1333MHz module
  • JEDEC-standard compliance ensures reliable laptop and NAS operation
  • Single 204-pin SODIMM simplifies DIY memory upgrades
  • Low 1.5V voltage reduces power draw in portable systems
  • CL9 latency supports smooth multitasking across open applications

Single-Module DDR3 Upgrade

This OWC module adds four gigabytes of DDR3 memory running at 1333 megahertz with CL9 latency. It targets owners of laptops, all-in-one desktops and NAS appliances that accept 204-pin SO-DIMMs and need a straightforward capacity increase.

204-Pin SO-DIMM Compatibility

The stick fits any system with a DDR3 SO-DIMM slot wired for 1.5 volt unbuffered non-ECC memory. Because it is a single rank 2Rx8 design it leaves additional slots free for further expansion when the platform supports more than one module.

Four-Gigabyte Capacity Headroom

Four gigabytes handles everyday multitasking, web browsing and light productivity workloads without swapping. Heavier workloads such as video editing, virtual machines or large databases will exhaust this capacity and require additional modules or a higher-density kit.

Highlights

  • Boost system responsiveness with a 4GB DDR3 1333MHz module
  • JEDEC-standard compliance ensures reliable laptop and NAS operation
  • Single 204-pin SODIMM simplifies DIY memory upgrades
  • Low 1.5V voltage reduces power draw in portable systems
  • CL9 latency supports smooth multitasking across open applications

Questions about this item

Does the CL9 latency at 1333 MHz become the bottleneck during long rendering or compilation sessions?

At DDR3 1333 CL9 the module runs at JEDEC-standard timings; sustained workloads will be limited by the 1333 MT/s data rate rather than the CAS latency itself.

How much heat does the 1.5 V unbuffered SODIMM produce when the laptop runs all day?

The 1.5 V DDR3 SO-DIMM has no heat spreader and draws standard JEDEC power, so thermal output stays within normal laptop memory limits during continuous operation.

Must the notebook already have a free 204-pin DDR3 slot that accepts 1.5 V non-ECC modules?

Yes — the upgrade requires an available 204-pin DDR3 SO-DIMM socket supporting 1.5 V unbuffered non-ECC memory.
