Hi Guys, Super frustrated. As recommended on the forum, I went ahead and bought Crucial Ram from Newegg for my 2011 15" mbp. I am currently on my 2nd set of RMAs for the ram sticks. I thought crucial should be the most stable brand for mac rams? Is this version of the mbp super sensitive? Anyone have the same experience? Or am I just unlucky? I am about to request a refund and to see if I can try my luck on another brand. Any recommendations? Oh and my mpb came with hynix brand ram sticks.
