I am not 100% sure what your asking, but I think you are worried if you damaged your CPU when you overclocked it because now you have worse performance at stock speeds.
What benchmark did you run? What are your system specs? How far off is the benchmark from where it was?
There are many things that can change benchmark scores. A small background process can make changes. I would make sure all my background activity is down and run several benchmarks and take an average of those benchmarks.
Ok listen I have done Valley Benchmark , my system specs are RX 580 8GB Pulse , i5 4460 , h81m-d2v.
The benchamrk score is far by 250 , and the highest fps score is behind by 20 fps and the average is behind by 5.
Same settins I have made a picture before I started ocing to remeber my old settings , which I used now to benchmark and it is still worse than before.
