Check your RAM timings (SPD may be an issue, so set the timings manually), and I also like to set all of the settings I can manually to assure the MoBo is not incorrectly assigning incorrect values (CPU Vcore, RAM Speed/Divider, RAM timings, stuff like that). I get the "Overclocking Failed" sometimes after a BIOS update, but once I go set all of my settings like I KNOW they should be, it does not return. I also disable my Parallel Port, Serial Ports, unused USB ports, etc. Just a habit of mine...
