I just got my new MBP i7 today ... WOW it's fast! It benches on Geekbench about 30% faster then my 7 month old 2.8 dual core MBP! Anyway back on topic ... I am going to some upgrades on it ... one being the memory. My question is any ddr3 ok to use. I saw some on ebay CHEAP ... $240 for 8GB (4GB x 2). It is some off brand stuff I am sure. There is another listing for some more main stream name brand memory but it is way way more expensive. So what do you guys think. Is all ddr3 created equal? What would you do?
