I recently purchased 8GB of RAM from Amazon.com for my Macbook Pro. So far the upgrade has been terrific. No hardware conflicts to speak of and the performance boost to VM-Ware Fusion running Windows 7 has been terrific. There is no longer any noticeable lag in either OS. I had read a few reviews about RAM upgrades that had gone bad so I went on the search for something to test the hardware. I found a great application called “rember” [http://www.kelleycomputing.net/rember/]. Rember provides a nice GUI for running a battery of memory tests. The tests ran successfully and all appears to be running well now after a few weeks with the new hardware.
Here is what I ordered:
Corsair CM3X8GSDKIT1066 XMS3 8 GB PC3-8500 1066Mhz 204-pin SODIMM Laptop Memory
I should mention that this was a considerable savings over the Apple upgrade price of $600.00.
