So - just received my MBP today, new, CTO. Got it with 7200rpm 750GB disk. Re memory, just ordered stock 4GB. I have read inconsistent posts on MacRumors that there are possible overheating issues or perhaps compatibility issues with going 16GB memory. Just trying to get a conclusive - DEFINITE statement, that it is safe to go 16GB. I always have used memory from crucial. They have memory for this config 16GB at $159. Any thoughts, suggestions. Will do SSD later, hopefully 512GB SSD for primary and 750GB original disk as secondary disk.
