Kit Contents

This OWC kit provides 8.0GB of DDR3 memory as two 4GB SO-DIMM modules. It is built for owners of compatible 2010 and 2011 iMac, Mac mini, or MacBook Pro models who need a straightforward capacity increase. The 204-pin unbuffered design matches the factory slots in those machines.

Who It Suits

The kit suits users upgrading the listed Apple desktops and notebooks, plus PC laptops, mini desktops, NAS or POS units that accept DDR3 1333 SO-DIMMs. Buyers whose systems require ECC or registered memory cannot use this non-ECC unbuffered kit. Those needing more than 8GB total capacity must look elsewhere.

Deciding Specification

The modules run at DDR3 1333 (PC3-10600) with CL9 latency at 1.5V. This exact speed and timing combination determines whether the host platform will recognise and stabilise the upgrade. The kit is backward compatible with PC3-8500 1066MHz slots, but the primary specification remains 1333MHz CL9.

Questions about this item

How much power does the 1.5 V DDR3 kit draw when the Mac runs all day?

The modules operate at the standard 1.5 V DDR3 voltage, so power draw matches any other PC3-10600 SO-DIMM and stays low enough for the iMac or MacBook Pro cooling system to handle without extra noise.

My 2011 Mac mini has empty slots — does this 204-pin kit plug straight in?

Yes, the 204-pin SO-DIMM form factor fits the 2011 Mac mini (5,1 / 5,2 / 5,3) slots directly; no adapter or extra hardware is required.

Will the CL9 1333 MHz sticks slow down to match the 1066 MHz memory already in my 2010 iMac?

The kit is backward compatible with PC3-8500 1066 MHz, so it will automatically run at the slower speed alongside the existing modules.
