Thanks mate, I think my Gigabyte DS4 is holding me back, I have some cherry picked Geil 6400 with different ram chips to the normal ones, (was a replacement from Geil when I had some 3 sets all DOA) they do around the 1000 mark, then I have the Kingston 8500 which was from the competition on here, must say it's stonking ram can get just over 1100 with 2.15v but both the Geil and Kingston seem that they have more left it's strange with the Gigabyte I'm sure the Asus would get better results.
