SKU CH-DW1Q-74EB9

A 4 GB DDR2 kit with two 200-pin SO-DIMM modules rated at 667 MHz and 1.8 V for the specified Apple MacBook

  • DDR2 667 (PC2-5300) matches factory memory speed exactly
  • CL5 5-5-5 timings at 1.8V deliver stable operation
  • 200-pin SO-DIMM form factor fits the 13-inch Core 2 Duo slot
  • Lifetime warranty from CMS backs long-term reliability

Targeted MacBook upgrade

This 4 GB kit supplies two 2 GB DDR2 SO-DIMMs built for the mid-2007 white MacBook Core 2 Duo 2.16 13-inch (model A1181). The modules match the factory 200-pin layout and 1.8 V voltage, so they install directly into the two available slots without configuration changes.

Capacity and headroom

The pair delivers the 4 GB maximum the MacBook can address, giving full headroom for macOS Leopard or Snow Leopard plus typical period applications. With both slots populated, no further memory expansion is possible on this platform.

DDR2 667 interface limits

The PC2-5300 667 MHz interface caps bandwidth at the DDR2 generation ceiling, so memory-intensive modern workloads will bottleneck here. The CL5 5-5-5 timing is fixed by the standard, and the unbuffered non-ECC design offers no error correction for critical data tasks.

Spurningar um þessa vöru

Will these 200-pin DDR2 667 SO-DIMMs work in the other slot of my MacBook Core 2 Duo 2.16 if I keep one original 1 GB stick?

Yes, the kit is validated for the MacBook Core 2 Duo 2.16 13" white (model A1181, MB062LL/A) and each module is 2 GB PC2-5300 DDR2-667 CL5 1.8 V unbuffered non-ECC, matching the factory specification.

How can I verify both 2 GB modules are recognised at the correct 667 MHz speed after installation?

Open About This Mac → More Info → Memory; you should see two 2 GB DDR2-667 SODIMMs listed, giving 4 GB total at 667 MHz with CL5 timing.

What exactly ships in the box and is anything else required to complete the upgrade?

The package contains two 2 GB 200-pin DDR2 SO-DIMM sticks; no tools, cables or additional parts are included or needed for installation.
