Hi people on MR, I'm going to by a Macbook Pro (2011) 15" with the i7 2720, and I'm looking for an 8gb memory upgrade option. I would like it to be reliable, as in, people have done it before, (good warranty too?), and confirmed to work with the Macbook Pro Sandy Bridge. It should be at 1333 or 1600 mhz, I don't want a clock speed downgrade. I'm looking for 8gbs The memory should be below $150. Can this be accomplished? Thankyou!!!
