I've had pretty bad experiences with most brands of RAM. Corsair, Kingston, Crucial, and maybe a half-dozen 3rd party RAM's have all errored up on various systems I've owned throughout the years. They generally last up to 1 year, but after year 2 or 3, they start messing up. I've been looking to get Samsung RAM (what Apple provides) but can't really find a good deal for it online. Any recommendations?
