Bought 4 gig of this ram a couple of weeks back. It is in a gigabyte GA-MA770-UD3 mobo (http://www.overclockers.co.uk/showproduct.php?prodid=MB-180-GI&groupid=701&catid=5&subcat=805). Problem is the ram is defaulting to 800mhz rather 1066mhz. Any ideas why this is and how to adjust it? Btw processor is athlon x2 7850. Thanks
