32GB DDR3 Kit for Late 2009 iMac
This 32GB kit contains four 8GB DDR3 1066MHz SODIMM modules built for the 27-inch iMac (Late 2009). It targets owners of model iMac11,1 (A1312, EMC 2374) who need the maximum memory capacity those systems can address. The kit matches Apple order numbers MB953LL/A and MC507LL/A.
DDR3 1066MHz PC3-8500 speed ceiling
The modules run at DDR3 1066/1067 MHz (PC3-8500) with 1.50V unbuffered non-ECC operation. The iMac's memory controller locks the bus to this frequency, so faster DDR3 modules will downclock to 1066MHz. Total bandwidth is limited by the dual-channel architecture and the 1066MHz data rate.
Four-slot installation with 2Rx8 modules
All four SODIMM slots must be populated to reach 32GB, so each 2Rx8 module sits in a dedicated channel. The 204-pin keying prevents misalignment, but the tight slot spacing inside the 2009 iMac makes finger access difficult. A common issue is modules not fully seating on first press, which causes a boot chime with no video until re-seated.

Spurningar um þessa vöru
How do I know the 32GB (4x8GB) kit is the right capacity for my iMac?
The kit matches the 27-inch Late 2009 iMac (model A1312, EMC 2374) that accepts four SO-DIMM slots, delivering the full 32GB the system can address.
What does the 1066MHz PC3-8500 rating mean once the modules are installed?
The memory will run at 1066/1067 MHz, providing the standard PC3-8500 bandwidth the iMac's memory controller expects for normal operation.
Will the 204-pin DDR3 SO-DIMM interface work without changes in my Late 2009 iMac?
Yes, the 204-pin unbuffered non-ECC DDR3 SO-DIMMs are the exact form factor and electrical specification Apple specified for that model.
