I have a late 2011, Mac Book Pro with 4GB 1333 DDR3 ram and was thinking of upgrading to 16GB can you please advise which RAM I require so I can order asap
We would be more than happy to check what memory is compatible with your system.
So we can recommend the correct memory can you confirm the screen size and the processor speed of your system? This is the best way to check what memory your MacBook Pro can support.
For example i5 2.5GHz 15", this would tell us the correct model and then we can guarantee the correct memory.
