I wanted to spend a maximum memory capacity of my Macbook Pro 15 Inches early 2011.
I had already increased its 8GB memory with two modules Crucial 4GB 1333Mhz.
I heard about the Macbook Pro 2011 could increase their RAM sync speed from 1333 to 1600 Mhz.
This is due to the characteristics of SandyBridge, the processor is synchronized to the speed of RAM, not the Bus!
While researching a Youtube video showed the development of these modules to 1600 MHz.
Neither one nor two I see that Amazon France resell these bars ... I command!
Delivered perfectly packaged and blister in 3 days (thanks Amazon Prime), I installs in 5 minutes.
It takes more time to remove the 10 screws under the Macbook as to insert the bars.
In addition unlike my old barrettes, she clipped gently and heat sink poses no concern!
I now exceeds 11200 in GeekBench in 64 bits. I won 10 MB / s read with my M4 SSD 256GB!
Brief but happiness and above all the joy of throwing all my VMWARE machines and finally the ability to mount without flinching all my Full-HD videos of the weekend ...
To summarize 99 gift ... Ya that's not even thinking!
PS: I have the i7 2.2 Ghz. (The Macbook pro in 2249) and not the first model to 2.0 GHz. It seems that it is only from the 2.2 Ghz and above that we can upgrade the RAM in 1600 Mhz. TBC with Google ....
So if your i7> = 2.2 Ghz RAM = Buy these !!! :-)
