Rasalas PC3-8500 8GB Kit (2x4GB) DDR3 1066MHz Sodimm 2RX8 DDR3 1066 MHz 1067MHz PC3-8500S 1.5V CL7 Laptop RAM Memory for iMac Inter Mould

Worked great like it should doubled the speed of my MacBook pro

Had to return this memory upgrade because it would not work in my Macbook pro (Amazon return process was quick and simple). Ordered from a different vendor which was a Mac specialist and received parts that worked perfectly.

Nice and easy Installation. Upgraded my MacBook in less than 15 minutes. Basically a new computer that was 10 plus years old no runs up to date OS and serves my current needs.

Easy to install. Doubled the memory in my old MacBook Pro. Increased RAM really makes a difference in performance

Worked perfectly.

Totally satisfied with my purchase. I was able to upgrade my older, early 2009 iMac from 4GB to the maximum of 8GB and performance has dramatically increased, no doubt about that. Very happy !!! :) Its like I gave this computer exactly what it needed ! Superb value. A++

Swapped in this ram and an ssd and brought my over decade old laptop back to life.

Easy to install. Allocated all 8gb to MBP. Fast shipping. Good price.

slow, but it worked

Received this today...Initial impressions.....used 2 4GB pieces to increase the RAM from 4GB to 8GB in my Mid 2010 MacBook Pro 17 inch laptop.
