joe1946 March 15, 2011 10:36 AM The OWC 8GB upgrade kit cost $112.99 vs $1,599.99 for the 16GB upgrade kit so unless you run out of RAM most of the time I think the 16GB upgrade is a waste of money.http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_1333MHz_SDRAM Richie March 16, 2011 08:57 AM Yes, make do with the 8 GB for now and when the manufacturers realize that no one's buying, they could put them up on fire sale or come up with a way to install 2 8 GB in parallel. Alexander Cardosa July 5, 2011 05:54 PM The different in price makes no sense until you think who dumb some people can be about spec so I can see where Apple is really selling it to those people not because of any performance gain but because there is a fool born every day.

Without even commenting on your lack of proper English(considering English probably isn\'t your native language), Apple isn\'t selling the 16GB kit for their Macbook Pros, OWC is. Reading before commenting usually helps. Maximum Huge August 18, 2011 01:10 PM The upgrade is 919.99 - the price seems to be dropping rather quickly. much more reasonable now. Matt Wolanski September 8, 2011 04:53 PM Price is down to under $800. Not sure why people are talking about no increase in performance - for me the benefit is not performance but the ability to run multiple virtual machines at the same time. I am seriously considering the 16GB upgrade for a new Mac Mini Server that will be connected to a 12TB Thunderbolt array - and I may end up running several VMs with email, web, FTP, etc on that Mac Mini - at a fraction of the price and physical size (and weight and power and noise) of a full Mac Pro Tower. I already have the 8GB upgrade in my MacBook Pro 2011 - and very often run close to the edge of using it all but have to be careful that I don\'t run all my VMs for test and dev at the same time. Mike Smith October 21, 2011 10:39 PM Don\'t assume that what you do with a computer applies to everyone and that 16G is a \'waste of money\' / \'more money than sense\' - consider that some people will run Parallels, and then run fairly heavy usage compilers in that environment. At that point 16G starts looking small. Cam Slice October 22, 2011 12:50 AM True that, virtual machines are resource hungry. That\'s how ended up reading this article. The 300GB hardrive and 8GB memory in my 2009 MacBook Pro are just not enough these days. Considering switching to solid state drive too, but not sure about the reliability. Pinto Anto December 6, 2011 09:54 AM New Price is $429 ! Alex Gold December 8, 2011 03:03 AM Dang, the 16gb is already down to $399 :D.http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_1333MHz_SDRAMSo as of this writing, it\'s a default of 2gbs -- and either $200 for apple to upgrade it to 8gb, or $400 to custom install 16gb. Given the laptop\'s price, I think the extra $200 would be worth it :P.
