You should move your FSB to 166MHz not 165MHz. 2500+ is default at 11*166=1.83GHz, but the mobo will default every CPU you put on it to 100MHz to prevent the case that you pop a 100MHz Duron onto it when the default value is 166MHz, your Duron will not run at all.
BTW, my advice is: if you are using a HSF better than the stock cooling, bump the FSB to 200MHz and you'll get a 3200+ in return, no sweat.
If I agree with you... will you shut up?
