I have a used Gigabyte GA-MA785GM-US2H the CPU I used is a AMD Athlon II X3 455 triple-core processor I have unlock the from the AMD Athlon II x3 455 triple-core processor to a AMD Phenom II X4 B55 Processor Via Advanced Clock Calibration, but I won't stick it go back to the Athlon II X3 455 even time I shut down the PC. Is there any way for me to keep it unlocked?
