If it's Crucial PC2100 then it's very likely it will hit at least 150MHz ,mine did & with timings of 2-2-2-6

,if not I've not got a clue

,but might be worth a go ,what brand is it?
RAM dividers on my Nfrc2 mbrd never worked when I tried to run the RAM below the FSB.
And no probs ,glad you got somemore power out of it

Don't forget to give it a good stress test with Prime95.
