Apple iMac 20" 2.0GHz Kit

This 6 GB DDR2 SODIMM kit is built for the Apple iMac 20-inch 2.0 GHz Intel Core 2 Duo (MA876LL/A). It contains two unbuffered non-ECC modules, a 4 GB stick and a 2 GB stick, totalling the system maximum of 6 GB. Both pieces run at 667 MHz (PC2-5300) with CL5 5-5-5 timings at 1.8 V.

Upgraders hitting the 6 GB ceiling

The kit suits owners of that specific iMac who want to reach the factory memory limit in one purchase. It is not for machines that take a different pin count, a different voltage, or a different DDR generation. Buyers whose iMac already holds two 4 GB modules, or whose model accepts more than 6 GB total, should look elsewhere.

200-pin DDR2 SO-DIMM interface

The modules use the 200-pin DDR2 SO-DIMM form factor, keyed for PC2-5300 667 MHz operation. That single specification decides whether the kit fits; if the target system requires a different pin layout or a different memory generation, the memory will not install.

Questions about this item

Will the 200-pin DDR2 667 SODIMMs run alongside any original 2 GB stick I keep in the second slot of my iMac 20 2.0 GHz?

The kit supplies a 4 GB and a 2 GB module, filling both SODIMM sockets for the supported 6 GB maximum; keeping an old stick would exceed the two-slot limit.

How can I confirm the 1.8 V CL5 memory is recognised at 667 MHz after installation?

Open System Profiler on macOS and verify the reported speed shows 667 MHz and the total capacity reads 6 GB across both slots.

Does the box contain only the two SODIMM sticks or are tools or adapters included?

The package content lists two memory RAM sticks — one 4 GB and one 2 GB — with no tools, adapters or extra cables supplied.
