OWC

OWC ADIB00KH9O5N2 8.0GB DDR3 1066MHz laptop RAM

SKU CH-4NRH-ZMDZE MPN ADIB00KH9O5N2

An 8.0 GB DDR3 laptop module running at 1066 MHz with CL7 timing on a 204-pin SO-DIMM

  • 8GB capacity for demanding macOS workloads
  • DDR3-1066 speed matching Apple specifications
  • CL7 latency for responsive multitasking
  • 5V operation reduces power draw
  • 204-pin SO-DIMM fits MacBook Pro, MacBook and Mac mini

Capacity & use case

This OWC laptop memory module delivers 8.0GB of DDR3 SDRAM rated at 1066MHz with PC3-8500 bandwidth. It uses a 204-pin SO-DIMM form factor and operates at 1.5V with CL7 latency. The module is designed as a direct upgrade for compatible Apple MacBook Pro, MacBook and Mac mini systems.

Who it suits

Ideal for owners of supported Mac notebooks and desktops that accept PC3-8500 DDR3 SO-DIMMs and need a single 8GB stick to reach the system's maximum memory limit. Non-ECC unbuffered design matches the original specification for these platforms. Buyers whose devices require ECC registered memory, different pin counts, lower voltage operation, or higher per-module capacities should verify their hardware requirements before purchasing.

Deciding specification

The 204-pin SO-DIMM interface combined with DDR3-1066 speed and 1.5V operation determines whether this module will function in a given machine; only systems engineered for this exact electrical and physical standard will recognise and run the memory correctly.

Questions about this item

Should I choose the 8.0GB module or a smaller capacity?

The 8.0GB module provides the maximum single-stick density available in this DDR3 SO-DIMM line, giving 8192MB in one 204-pin slot.

What does the 1066MHz speed mean once installed in my laptop?

The module runs at DDR3-1066 with CL7 latency and a 1.875 ns cycle time, delivering PC3-8500 bandwidth at 1.5V.

Will the 204-pin DDR3 interface limit performance on my system?

The 204-pin SO-DIMM connector caps the module at the JEDEC DDR3-1066 standard, so throughput cannot exceed PC3-8500 rates.
