Corsair RAM is generally good quality and this pack is very good value as well, it's just a pity it didn't work with my motherboard.
I did extensive research before buying this RAM for my Intel DP45SG motherboard. I double checked it would be compatible by using the Corsair 'configurator' on their website which said this is the one to buy. So I did and then wondered why my new PC wouldn't boot up. It turned out that Corsair were wrong as this is incompatible with an Intel DP45SG....not only that, but Corsair don't make any RAM that's compatible. The annoying thing is that they've known about this for over a year, and they haven't amended their website so people like me will continue to buy something that won't work! If they had I wouldn't have wasted either my time or Amazons and had a lot less stress last Christmas.
Thankfully, Amazon refunded me so I was able to buy some Crucial RAM instead which worked no problems at all.
