What would happen if ram was the same freq. as cpu?

Well just as the title stated...
If your ram was at the same frequency as your cpu, ie cpu=2.5ghz, ram=2.5ghz
Would your computer even use the cpu's cache?
Would the computer be really really fast?
Would this work?

It would never work, but if some God granted you ram that could operate at those frequencies, your cpu would still use the faster cache. Your system uses memory in the following order as needed:
1) L1 cache
2) L2 cache
3) System Ram
4) Pagefile on hard drive

These are also in descending order of speed.

Really?
BTW I was being hypothetical, I know there is no way ram could run at those frequencies. Would there be a massive gain in performance though?
