Hi , i have upgrading my bios for my z68xp-ud4 to F4 from F1, running prime95 i discorver my cpu was x37. The problem is in my BIOS the multiplier is set to x33. Even if i load "Optimized bios" the issue persist. In easytune i got Deafult : 3.7ghz CPU1: 3.77 CPU2: 4.33 CPU3: 4.47. What's going on? Seems that all the value are wrong?!?! Is the bios setting turbo mode automatically?
