Somewhere in time...
Hello all, I thinking about buying an 8gb memory stick for my early 2011 13" mbp (I have 4gb now - 2x2), but I'm not sure if it will cope with the strange combination of a 2 and an 8 gb mem sticks. I know it can get up to 16 gigs with no problem, given that both sticks will be an identical(?) pair of 8gb's.

What do you think?
 
It should work, but it will run is single channel mode instead of dual/triple channel mode.

It should work fine. There is a slight advantage to using matched pairs of RAM.

Great, thank you guys!

I'm placing my order right now. Maybe I'll buy another 8gb stick in the future to match it for the dual channel.
 
BTW, has anyone tried putting 1600MHz memory in that mbp? Will it work at that speed, or will it be downclocked? If both sticks are rated for that speed that is.
 
It should work, but you're better off using matching sticks of RAM to enable dual channel mode.
