Compatible Mac Mini upgrade

This 4GB kit contains two 2GB DDR3 1066MHz SODIMM modules built for the Apple Mac Mini "Core 2 Duo" 2.0 (Early 2009). It matches the factory specification of PC3-8500, CL7 timing and 1.5V operation. The 204-pin unbuffered design installs directly into the two available slots.

Suits original-spec restorations

The kit is intended for owners restoring or maintaining the exact Early 2009 Mac Mini model identified as Macmini3,1 or A1283. It will not fit later Mac Mini revisions that require different memory generations, higher speeds or larger capacities per module. Buyers needing more than 4GB total or ECC functionality should look at other solutions.

DDR3 1066MHz PC3-8500 specification

The decisive specification is the DDR3 1066MHz (PC3-8500) rating with CL7 latency at 1.5V. Only modules matching this exact speed grade and voltage are validated for the named Mac Mini. Confirm the system model is Macmini3,1 before purchase.

Questions about this item

Will this 204-pin DDR3 SODIMM kit work in my Mac Mini 3,1 (A1283) from Early 2009?

Yes, the kit is built for the Mac Mini "Core 2 Duo" 2.0 (Early 2009) with identifiers Macmini3,1 and A1283, matching your system exactly.

Can I mix these CL7 1066MHz modules with the original 2GB sticks already in my Mac Mini?

The Mac Mini 3,1 has two slots; this 4GB kit (2 x 2GB) fills both, so the original memory must be removed rather than mixed.

How do I confirm the memory is running at 1066MHz with CL7 timing after installation?
