Ok, so i bought a 16GB DDR3 1333MHz RAM for my late 2011 13" MacBook Pro whose memory runs at 1067 MHz (I was also told that late 2011 MBPs run at 1333MHz, is mine an exception?)... Im looking for all possibilities to close the compatibility gap...

You bought the right RAM. If you actually bought the 1333MHz

2011 MB Pro's run at 1333MHz.

You were probably sold 1066MHz RAM instead of what you need.

Go back and exchange it to what you need.

See this technical specifications page - http://support.apple.com/kb/SP645 - you bought the right RAM.

Top right, click on the apple, then click on about this MAC, then click on more info, go to system report, click on memory, what does it say?

You don't have a late 2011 MB Pro.

You have a 2010 version. Your MB doesn't support 16GB. 8GB Max.

That's what it shows on your about this MAC.

You need to return the RAM and get 8GB ( 2 X 4GB ) 1066MHz.

Your system bus is set to 1066MHz.

You're having issues because you've installed more RAM than your MB can support. It's only reading 4GB per bank which totals to 8GB and not 16GB.

no you can not. it will be cheaper for you to buy a new mb pro than replacing the board and stuff.

what you can do is max out your RAM at 8GB and invest some $$$ to get a SSD installed in your mb and it'll run pretty fast.

your mb is fine. just adding the RAM and moving to SSD will improve your performance drastically. It's like getting a new mb.

Solid State Drives runs faster because it doesn't have any moving parts.

It also saves your battery.

Your hard drive has platters that spins with read and write heads that goes up and down to retrieve your data.

The SSD however, doesn't have any of those and your files are available instantly.

not really but you can do the apple recycle.

here's some info about it.

A SSD will dramatically anything that accesses the hard drive - boot time, loading applications, using your internal as a scratch disk: anything. I have the Crucial m4 512GB which runs about $400 now ($600 when I purchased it). Together with my RAM upgrade, I have one of the fastest non-Retina machines going now.

Its a great investment.
