I tried to overclock my i7 4770k with raising the cpu ratio to 45x. Suddenly after pressing the apply button, my computer suddenly restarted. After the restart the multiplier was 40x again. Could my CPU have been damaged or anything in that way?

no you didnt damage anything, its normal. you just need more voltage than the cvid can automatically adjust to for that 45x multiplier. will it let you boot into windows with a 44x multiplier? lf so download hwmonitor to check your temps and voltages and then download intel burn test and run it at maximum stress level and see if you crash again, takes about 25-35min. if your temps on the cores are going above 80c then you need better cooling. turn off the stress test and bump down to a 43x multiplier or lower until you can hold under 80c. after thats all working for you run prime95 small fft test for about 12 hours as a final stability check. just keep hwmonitor open to log your min/max voltages and temps.

The only way you will damage anything is too much voltage or too much heat. Yours just became unstable and shut down. The biggest risk is screwing up the OS with repeated shutdowns like that. I would do a image of your C drive if you are going to mess with OCing. That way if the OS gets messed up you have an image to fall back on.
