What are the best OC's for fsb266 chips using multiplier alone?

[niteshs]

I need to change my chip as I damaged my 1600+ during a heatsink swap.

My board doesn't allow fsb increments between 133 and 166 (the latter being imcompitible with my DDR266) so I am restricted to using the multiplier alone for OCing.

The options are duron 1600/1800 & athlon xps up to 2400+.

Get a mobile chip. all desktop versions are locked, so you won't be able to change your speed at all.
