Mac Mini Late 2009 8GB Kit

This 8GB kit contains two 4GB DDR3 SO-DIMM modules rated at 1066MHz with CL7 timing. It is built specifically for the Apple Mac Mini "Core 2 Duo" 2.66 (Late 2009) models identified as Macmini3,1 and A1283. The unbuffered, non-ECC design matches the original system requirements exactly.

Suits Late 2009 Mac Mini Owners

Buyers restoring or maximising a Late 2009 Mac Mini will find the correct 204-pin form factor and 1.5V voltage. Systems that require ECC, registered memory, higher speeds or a different pin count cannot use this kit. The two modules fill both available slots to reach the 8GB maximum.

PC3-8500 1066MHz Speed Rating

The decisive specification is the DDR3 1066 (PC3-8500) speed grade combined with CL7 latency. This matches the memory controller of the Late 2009 Mac Mini, ensuring stable operation without downclocking..modules rated at other speeds or latencies may not be recognised or may cause instability.

Questions about this item

Will these 204-pin DDR3 SO-DIMM sticks fit the two memory slots in my Late 2009 Mac Mini A1283?

Yes, the kit matches the Mac Mini 2.66 Late 2009 specification exactly: two 204-pin DDR3 SO-DIMM modules, PC3-8500 1066 MHz, 1.5 V, unbuffered, non-ECC, 2Rx8 rank.

What is the correct way to seat both 4 GB modules so the Mac recognises the full 8 GB?

Power off, unplug, remove the bottom cover, spread the retaining clips on each slot, align the notch on the module with the key in the socket, press firmly until both clips click shut, then replace the cover before powering on.

Do these modules need any cleaning or component replacement during their service life?

No routine maintenance is required; the sticks have no heat spreaders or moving parts. If a module ever fails, the limited lifetime warranty from Computer Memory Solutions covers replacement.
