I must have been too tired when I ordered my Christmas presents and ordered 2-4GB DDR3 PC3-12800 SODIMM for my MBP. Before I do anything, can I just install this and call it a day, or is it going to give me kernel panics and headaches? I'm just itching to get this thing running faster and I don't want to send the ram back. The machine is spec'd for 1066 I guess. Anyone out there with real world experience that can chime in? Happy Holidays!
