I'd like to upgrade my laptop memory from 4 GB to 8 GB. Which memory would you recommend I buy? Crucial, Corsair, Samsung or other? I'd like to get the best quality memory and I'm not really concerned about price.
Also, what is the qualitative difference between DDR3-1066 CL 7 vs. DDR3-1333 CL9? And, how do I find out what type of memory is already in my laptop?
