I have a 15in MBP with the following specs: Processor: 2.66GHz Core i7 (620M) Codename: Arrandale Graphics: NVIDIA GeForce GT 330M (256MB) + Intel HD Graphics (256MB) Model Number: A1286 Sales Number(s): MC373LL/A Machine Number(s): MacBookPro6,2 I replaced the memory to 8GB, now i'm greedy and want 16. Is this possible? What will happen if I do it? thanks!!!
