3 Introduction Systems based on the platform technology codenamed “Scorpius” may be tuned to deli v er added system perform a nce. The AMD FX™ CPUs and th e AMD 9-series chipset motherboards offer an exci ting amount of performance tuning options, incl u ding potential overclocking headroo m.

5 Glossar y of Terms – c ont inued CPU / CPU NB Voltage OFFSET: Most AMD “Scorpius” p latfor m technology m otherboards have a BIOS opt i on that allows Voltage ad j ustments beyond th e C PU V ID Voltage range. This voltage offset is added on top of the VID v a lue.
