8GB DDR3 SO-DIMM kit for Early 2009 Mac Mini

This 8GB kit contains two 4GB DDR3 1066MHz SO-DIMM modules built for the Apple Mac Mini "Core 2 Duo" 2.0 (Early 2009). It uses 204-pin unbuffered non-ECC memory running at 1.5V with CL7 timing. The kit is designed as a direct memory upgrade for that specific system.

DDR3 1066MHz speed and 8GB capacity limit

The modules operate at the DDR3 1066 (PC3 8500) standard supported by the platform. The Early 2009 Mac Mini officially supports up to 4GB, but can unofficially address 8GB after applying EFI Firmware Update 1.2. Without that update the full 8GB may not be recognised by the system.

Unofficial 8GB support requires firmware update

The single specification that decides fitment is the requirement for EFI Firmware Update 1.2 to enable the full 8GB capacity. Buyers who cannot or will not apply that firmware update should not purchase this kit, as the system will remain limited to its official 4GB maximum.

Questions about this item

Should I choose the 2 x 4 GB kit or a single 8 GB module for my Early 2009 Mac Mini?

The kit supplies two 4 GB SODIMMs, filling both slots so the Mac Mini can run in dual-channel mode; a single 8 GB stick would leave one slot empty and halve memory bandwidth.

What does the PC3-8500 1066 MHz rating deliver inside an Early 2009 Mac Mini?

It matches the Mac Mini's native 1066 MHz bus, giving the maximum throughput the platform supports without down-clocking.

Will the 204-pin DDR3 SO-DIMM interface work in my Early 2009 Mac Mini without changes?

Yes — the 204-pin DDR3 SO-DIMM form factor is exactly what the Early 2009 Mac Mini requires, and the modules are unbuffered, non-ECC, 1.5 V parts that the system accepts.
