OCZ Blade 1150 not running full speed

Hello, Im new to computer building but please help me out I have an Asus m4a78 pro motherboard which supports 1066 ram (I am aware i have bought 1150 but its not that bigger deal). Either way, it is currently running at 800 mhz. Please can someone tell me how to safely get it running at the full speed? With the correct settings? I have had bad experiences with my computer being unable to boot in the past and i dont want to screw it up again! Note: according to asus's website, my ram can be overclocked to 1200 safely? Anyone have any thoughts on this? I am happy with 1066! Any help is GREATLY appreciated, and in case this helps, Im running windows 7 64bit and have a phenom II x4 965 at 3.4ghz. p.s. here is a link to my ram: http://www.ocztechnology.com/produ [...] ade_series and here to my motherboard: http://uk.asus.com/product.aspx?P_ [...] templete=2 thanks in advance!!!
