Anyone in the market for one of Apple's new Thunderbolt-equipped 2011 MacBook Pros would be forgiven for thinking the machines only support up to 8GB (2 x 4GB) of RAM since that's what's listed on the tech specs and is the maximum build-to-order option available through Apple. However online store OWC says the new 2011 MacBook Pro models can actually support up to 16GB (2 x 8GB) and is selling the 8GB sticks you'll need to make it happen. The only catch is the price, which is more than the asking price for either of the two 2011 13-inch MacBook Pro models currently available.
All the 2011 MacBook Pro models come with 4GB of 1333MHz DDR3 memory as standard, which should be fine for most applications. But if you're a power user dealing with video editing, high resolution images or the like, then shelling out an extra US$200 to bump the RAM up to 8GB can be a wise investment – and sourcing the RAM from someone other than Apple can bring the price down to almost half that.
But if at 8GB you're still thirsting for yet more speed, then OWC is happy to oblige with a 16GB (2 x 8GB) DDR3 1333MHz Memory Upgrade Kit that sells for US$1599.99, with the high price tag attributable to the scarcity of 8GB modules. However, at this price you'd have to do a serious cost/benefit analysis and ask yourself whether you actually need what, for most users, would probably amount to a minimal speed increase. For the slightly more budget conscious OWC also sells a 12GB (8GB + 4GB) Upgrade Kit for $879.99.
