Compatible MacBook upgrade

This 4GB DDR3 SODIMM is built for the Apple MacBook Core 2 Duo 2.4 13 Unibody from late 2008. It matches the factory memory specification so the notebook recognises it immediately without configuration. The single stick plugs straight into one of the two available slots and delivers 1066MHz operation at CL7 latency.

Suited for single-slot top-up

Owners who need a straightforward capacity increase for everyday tasks will find this module fits the original slot layout. Systems already running the maximum 8GB across both sockets or users who require ECC error correction should look at other memory types because this stick is non-ECC and unbuffered.

Fits the original memory array

The 204-pin DDR3 form factor aligns with the MacBook5,1 architecture and runs at the standard 1.5V supply voltage. Installing it leaves the second socket free for a matching module if a future upgrade to the full 8GB limit is desired. No heat spreader is fitted, keeping the profile low for the slim unibody chassis.

Questions about this item

What MacBook model and year must I already have for this 204-pin DDR3 SODIMM to fit?

This module is built for the 13-inch MacBook "Core 2 Duo" 2.4 (Unibody) from Late 2008, model identifiers MB467LL/A, MacBook5,1, A127.

Can I keep my existing 1066 MHz DDR3 stick and add this 4GB CL7 module in the second slot?

Yes, the MacBook has two SODIMM sockets supporting up to 8GB total; this 4GB PC3-8500 CL7 stick will run alongside another DDR3-1066 module at the same speed and voltage.

How do I confirm the memory is running at 1066 MHz with 7-7-7 timings after installation?

Open About This Mac → System Report → Memory; the installed module should show 4GB, DDR3, 1066 MHz, and the part number CM512648500SODRH.
