I bought the Corsair Vengeance, as they are one of the few 4GB RAM that supports my motherboard. As far as I'm happy with it. The memory works stably and professionally processed. But now my problem, why I give only 3 Stars. The Corsair Vengeance memory is 53mm high. When unpacking first I thought so, oh oh that is so huge. As far as that's not bad, but if one wants to buy a good CPU cooler, because most of the boxed cooler is too loud or not cools enough or you just want to overclock, then he is not enough, you have to be extremely careful. I have the Gigybyte GA970A-UD3 motherboard. In this, the RAM slots are already sitting pretty close to eh the CPU socket, but now even more will be added that so many CPU coolers, the RAM plug-place be built over must or the CPU coolers are a play on the memory. Now that the Corsair Vengeance is 53 mm high, I now hardly a good CPU cooler found which is sufficiently high to get over the memory over. Finally, I have a very good find. The Alpenföhn Gotthard leaves enough space to exactly (approximately 2-5mm square) on the Corsair Vengeance memory to come over. However, one must definitely consider beforehand how much RAM you want to have now. If the cooler installed only once, there is added no chance at the slots. Except you make the CPU cooler again only from, then on again, But that can not be the intention. So please be careful if you for this great RAM comes into question. There is a very good video I've found, for the installation of a Alpenföhn Gotthard on a Corsair Vengeance so it's definitely possible.
