Can I install a pair of PC3-10600 8 GB RAM Chips?

I'm not sure if both this guide and Apple's own support information is just guilty of assuming that the maximum memory supported is based on RAM boards available at the time or not. This guide seems to suggest that you can only upgrade to a total of 8GB of RAM maximum (4 GB RAM sticks x2 slots) based on the list of "Relevant Parts".

When looking up support on the product it's self the PC3-10600 8 GB RAM Chip clearly lists a MacBook Pro 13" early 2011 with "2.3 GHz (Early 2011)" beside it.

Could someone please clarify if an upgrade to a total of 16GB (2x 8GB sticks) is possible? I wouldn't want to make the purchase and find out that I've made the mistake then. (esp. at the cost) Thanks!

...and if so maybe update the guide? :)

Yes it can be confusing!

First here's Apples TN on what Apple supports MacBook Pro: How to remove or install memory. Now you need to look at this as Day One support listing not what it Can Support today. Apple does not retest their systems with newer memory modules (no different than the other manufactures) which is why this is the published listing. Tim Cook made a statement at the last WWDC stating Apple would support systems which have been upgraded to 16GB with the new EFI firmware that had been released just before the conference.

The IFIXIT guide page shows what IFIXIT offers based on the Apple support page & when it was created (as best as I know).

As to what your system Can Support: Yes, you can install two 8GB modules to have a max of 16GB of RAM (Review this EveryMac). BUT you need to upgrade the EFI firmware BEFORE you install the modules. Follow this Apple TN on how to update EFI & SMC firmware updates for Intel-based Macs.

As to why the confusion: This is benefit of the improvement in technology. When the this system was being created the technology in making lower power and larger storage memory chips was still on the drawing table. Today these low power high capacity chips make it possible to upgrade your system with little power loss (when on battery). Even moving to a SSD Vs a spinning HD gains even more life on battery.

Just make sure you get a matched pair of modules - And enjoy the added performance having more memory give you.

Great information! Thanks for the clarification and the added note about the firmware. Don't think I could have asked for a better answer.

It seems that I already have the current firmware so it must have come via the usual System updates. (Something I do pretty regularly as they come out)

This'll probably be my next upgrade! :)
