System-specific DDR3 SO-DIMM kit

This 8 GB kit contains two 4 GB DDR3 1333 SO-DIMM modules built to PC3-10600 specification with CL7 timing and 1.5 V operation. The unbuffered, non-ECC sticks use a 204-pin layout and 2Rx8 organisation. Computer Memory Solutions validates compatibility with the Apple systems listed in the specifications.

Suits owners upgrading a listed iMac.

Buyers whose Mac requires a different DDR generation, ECC registered modules or a higher total capacity than 8 GB cannot use this kit. The two-slot limit on supported machines also means no further expansion is possible beyond these two sticks.

204-pin DDR3 SO-DIMM form factor

Only systems that accept 204-pin DDR3 SO-DIMM memory at 1333 MHz with CL7 timing and 1.5 V voltage can install these modules. Verify the exact model against the compatible list before purchase.

Questions about this item

What real-world bandwidth does the PC3-10600 rating deliver once installed?

The PC3-10600 rating corresponds to a peak transfer rate of 10,600 MB/s at 1333 MHz, which is the maximum theoretical bandwidth the memory controller can use in compatible Macs.

How does the 204-pin SO-DIMM interface limit upgrade options on these Macs?

The 204-pin DDR3 SO-DIMM slot is the only memory interface on the listed iMac, Mac mini and MacBook Pro models, so only unbuffered, non-ECC DDR3 modules at 1.5 V can be used.

Will the two 4 GB sticks fit the 27-inch iMac (Mid 2010) and 15-inch MacBook Pro (Early 2011) without clearance issues?

Yes, both systems use standard 204-pin SO-DIMM sockets with two slots; the low-profile modules have no heat spreader and match the 2Rx8 rank layout specified for those models.
