Effect of cache speed on CPU OC

So I understand overclocking core speeds to be allowing more clocks per second. This is in effect allowing more bandwidth, which is similar to installing a bigger pipe for more data flow.
Now, with that, I understand there's many other factors that come along with it. Just because it can make more calculations or accept more data doesn't necessarily mean it's being fed more data at once, therefore not quite bringing a 100% ratio of performance for every clock you go over standard.

I would assume the different CPU caches clock speeds and the memory would be a couple that have an effect on this particular situation?

What other factors are included?

Also, is it possible to increase these? (other than memory I've messed with that)

It just depends on the application if all of the data that can be cached fits then making it faster won't have a giant benefit, but if it's constantly swapping stuff out then it will help. As for you pipe analogy for overclocking don't think bigger pipe think bigger pump. If there is enough water (data) for the pump to pump more it helps. If not it does nothing

Ah, it's memory clock rates that are more so a pipe analogy. That makes sense.

So if the data is large enough it may have to be held in a cache and in that case it may be beneficial to up cache rates, but if the instruction set is smaller, it may not even have a difference?

Usually I oc the cores as much as I can "comfortably" if the chip hits a thermal wall I'm done. If it just hits a wall where it won't go higher I always oc the cache. If it hits a wall from a voltage standpoint I'll try to do the the cache but sometimes it works sometimes it'll still hurt stability
