Just got this in the mail: GIGABYTE's own Llano OC Tweaking Guide. The document includes the basics on overclocking the A55/A75 Llano platform as well as benchmark results and key performance bottleneck indicators. Interesting read for those who want to get more out of their GIGABYTE A55/A75 mainboard!
