Your memory speed is IDEAL right now for your CPU speed. If you overclock your CPU bus to 250MHz, your memory will be running at full speed.
Your GeForce2 should be able to handle ANY overclocks on that system, these cards were FAMOUS for handling high bus overclocks, and I doubt your board overclocks the AGP bus automatically anyway.
So it looks like your REAL problem is getting your CPU overclocked to 250MHz FSB! And that would be a good question for the CPU's Overclocking forum!
