Just got my new MBP today and instantly upgraded the RAM to 16 gig. It failed Apple's hardware test, ran memtest and got an error too. Any suggestions on replacement, I was using Gskill 8gig x2 sticks from newegg, cost about 85 bucks. Should i try corsair? I have an RMA ticket, but im tempted to return it and try diff brand. Any suggestions ---------- found this http://www.newegg.com/Product/Product.aspx?Item=N82E16820148609 exchange for this one, or corsair?
