My CPU (AMD FX 8120 Black Edition) Is running at a speed of 2812MHz or 2.81GHz according to the BIOS, EasyTune 6, CPU Z, AMD OverDrive and Windows 7. I am totally "stumped" as to why the processor is running at this speed, AMD clearly states that the FX 8120 should run at a core clock speed of 3.1GHz. I have the same motherboard, I updated the BIOS to a newer version thinking it was that and even went into the BIOS and changed the multiplier myself to x15.5 to achieve the desired speed of 3.1GHz. Although after an eratic clock speed, I changed it back as it would keep dropping to around 2.1MHz and then back up to the core clock speed of 3.1GHz. As I am using a GIGABYTE motherboard I thought someone might just be able to help me out here. Peformance is poorer to say the least. I really hope for a solution, please reply quickly so I can move on. Many thanks!
