Except for the price, I am very pleased that last possibility to get a little juice out of my Board! (High price compared to equivalent DDR3 memory) All in all, he does his super service, in conjunction with my Q9550 it bring both the W-performance index to an astonishing 7.3 out of possible 7.9! So for anyone who does not want to throw half the inner workings of its PCs in the garbage that's a good last alternative !!!
