You'll lose dual channel capability (minor speed boost) but it should work as long as you can use 8GB in a single slot on that model.
What is the Model ID of your MBP? (click the Apple, select About This Mac).
Most of the 2008-2010 MBPs max at 8GB. The 13.3" 7,1 model supports 16GB, though.
Dont have my MBP on me right now but the max is 8gb or else I would have just boosted to the 16GB. Would it make any difference if i just left the original 2gb stick in the with the 8gb even though it only supports a max of 8gb?
I've heard in some case sometimes things mess up (like computer might glitch or not be as fast as it could), but rarely, and imo it's best to just use two sticks. I went with Crucial ram. For what's it worth, the price was only slightly a little higher to get two sticks rather than one.
Sadly it wont work as in all cases if its 8 gig max that means across both dimms (ram slots) you cant max out the full ram capacity on one dimm. It may work for a short term but as the laptop is useing a lot more power to run the full 8 gig it alleviates that power across both slots,( for example as say you went shopping and you bought a load of food and you put it all in one bag but that bag then becomes heavy so you decide to take away some strain and separate that shopping in to two bags and all of a suddon they become better to carry because your removing the strain of all that weight on one arm and levelling it out with both your arms. )That's what happens with your motherboard as well. because it sends the power to one slot it sort of confuses it and basically fucks up your mac eventually so it is always best to get 2 sticks of 4. Also yea check the motherboard and timings of the ram and the mhz speed as well so you know for sure there compatible.
I can't say, I've never tried to use more RAM than a machine can support. It might only recognize the 2GB for all i know
I haven't done it on a Mac, but on PC's, if your motherboard only supports a certain amount of RAM, that is all it will recognize, regardless of how much you really have in there. I know for a lot of motherboards there are Bios for them that "unlock" the board. This will usually allow you to go crazy with ram.
