The price is a great deal! I ask myself...ummm will the memory make my XPS 8300 a King of Beast? Yes! Great product and Yes it is the best deal I have found for memory yet. DDR3 PC3-10666 was picked up on my machine without a problem. I deal with a ton of files, graphics, and photos--Just what the doctor ordered:) My machine is happy, I'm happy, and it ROCKS! It's not Zero Wait time, but it's really close to it. I can't wait until the 32 gig memory drops a bit:) The best part is the package actually arrived one day early! Now how can you beat that? Great price and service--Amazon is the epitome of customer service!
