Fella, it would be nice and server you better in getting help if you would explain in some detail exactly how you have gone about doing your OC. Like but not limited to, did you save your OC to your UEFI and have you loaded it? Is the OC you did stable or did you have a crash? What did you change, multiplier and or BCLK? What MOBO are you trying to OC on?

I have an msi x99a sli plus i overclocked the multiplier and yes i saved it and loaded it. I had it working fine until i had to reinstall windows yesterday now it doesnt recognise the overclock at all i have tried setting it to defaults and redoing the oc but to no prevail

You mean like this, Windows will only register the base clock speed, not overclocks:
