I have an old Athlon XP 1900+ (Palomino), and tried to unlock it. My MB is Gigabyte GA-7N400E. When i put the multiplier to 12.5 (default is 12x133), BIOS recognizes it like 12, and when multiplier is on 11.5 BIOS says 11 (cpuz also says 11x133) ?!? Should i consider the CPU is unlocked or try again ?
