4 GB DDR2-800 SoDIMM for Apple

This 4 GB DDR2-800 CL6 SoDIMM is built to the Apple 971741A specification. It targets owners of compatible Mac notebooks or desktops that require PC2-6400 non-ECC memory. The module installs directly into the factory memory slot without adapters.

Sustained CL6 latency at 800 MHz

Rated at CL6, the module maintains its timed latency during extended workloads rather than only in brief bursts. The DDR2 interface delivers consistent throughput for everyday applications and older macOS versions. Stability is preserved across long sessions in supported Apple hardware.

Verify your model uses PC2-6400 SoDIMMs

Check that your system accepts 200-pin DDR2 SoDIMMs at 800 MHz with non-ECC operation. Apple machines that shipped with different speeds or form factors will not recognise this module. Confirm the exact part number requirement before ordering.

Questions about this item

How much heat and noise does the 800 MHz DDR2 SoDIMM add when the Mac runs all day?

The module is a standard DDR2-800 CL6 part, so its power draw is modest and it does not require active cooling; the system's existing fans handle the extra heat quietly.

Which Mac models accept the 971741A part number so I know it will work?

Apple lists 971741A as the service part for several DDR2-based MacBook and iMac models; match that number to your machine's upgrade guide before installing.

Can I pair this 4 GB stick with the original 2 GB modules still in the slots?

The SoDIMM is non-ECC CL6 DDR2-800, matching the speed and timing Apple specified for those systems, so it will run alongside the factory memory at the same 800 MHz rate.
