I bought this because it seemed a popular choice, and got good ratings.
I stuck it in my new PC build and, with all the other stuff plugged in and powered up, the PC works. Brilliant. I had to replace two sticks with the Corsair Vengeance LP sticks when I bought a BIG CPU cooler though, which means I also have two spares - bonus!
I've noticed I feel more cleverer since I bought this, and I've noticed girls checking me out more often on the bus. I thought I was getting old and past it, but I appear to be back with a 16 GB vengeance kit.
I was really impressed with the packaging on my Corsair PSU, which is why I opted for the Vengeance instead of any other brand. I also bought Corsair SSDs which are equally brilliant.
