seems ok, ddr3 1600mhz but is there anything ive missed? i have 4gb now, putting 8gb in alongside one of my 2gb to make 10 then ill put in another 8gb later to bring it up to 16. i want to be able to go to 16gb if my virtual machine needs it.

----------

the crucial one is a lower voltage, which i assume is better? anything else im missing?

Lower voltage is better but you have to make sure all the RAM is 1.35 volts or they will all run at 1.5 volts.

1.35 as standard isnt it? ill just get the crucial one.
will running an 8 and a 2 be faster than 2x4? i know when they match it runs in a different mode?

Yes that ram is fine and will run fine.

As said above, that will work fine. I happen to have 2 of those in my 15" 2012 MBP.

One caution, doing the mix'n'match with memory MAY result in degraded performance. If you really can only afford one stick now, only use the 8 GB, leaving you open fo upgrading down the line. If you don't think you'll ever upgrade beyond 8 GB, get a 2x4GB kit instead.

http://en.wikipedia.org/wiki/Dual-channel_memory

SOME chipsets (does Apple use them?) allow the use of "Flex Mode", which will dual-channel what can be "matched" (2 GB from each module in this case) then single-channel the rest (the remaining 6 GB from the new module). However, if the latency on the standard memory is higher than the Corsair (which is rated for 10 which is better than average for this speed memory right now), you may run into problems even if you had similar-sized modules. If the Mac reads the module properly, it SHOULD drop the latency to match the stock memory.
