Not sure why this only rated 3 stars, it's definitely a 5 star product. I easily overclock mine to 5200 MHz and it runs stable and cool. I honestly can't believe its rate 3 star simply because of "the aesthetics" of the RAM. Does it have a cool looking, but totally unnecessary heat spreader? Nope, doesn't need it, even when overclocking to 5200; if I was going to do radical overclocking, then maybe. All in all, solid, stable RAM with great headroom at a fair price is 5 stars in my book.
