Multiplier has got stuck in Windows...help required

I have no idea how this has happened, but the multiplier setting appears to have got stuck to a certain setting when I boot into windows.

I have a i3770k running on a Asus P8Z77-V Pro board.

It is set to 44 in the bios, but when I boot into Windows it appears it gets changed to 45. Initially I thought it was something that TurboV was doing, but I uninstall the whole AI Suite and it is still happening.

I go back and try and change the bios, and no matter what I change, the multiplier stays locked at 45 in Windows. I can make alterations to the VCore etc in the bios and those changes appear when running Windows, but the multiplier stays locked at 45, no matter what I have set it as in the bios.

Where in Windows are you seeing a x45 multiplier? Try resetting CMOS, then re-do your overclock from scratch.

this kind of range of possibilities is why I am hesitant to appreciate software overclocking

at lease yours will overclock.. i set my multipler to 44 and vcore in the bios, and when i get into windows the vcore is increase like i set it in the bios, but the multipler is stuck at stock. when not under load it drops like its suppose to but when i run prime95 on 4 cores it only goes up to like 36, one core 38 ( the defaults for the i5-3570K )
