Your barton is designed to run at 166 fsb (166x2)
Your pc2100 is designed to run at 133fsb (133x2)
My suggestion is to pick up some pc2700 or better ram and turn that barton loose.
With the pc2700 (or better) you will see a 30% increase in speed.
With the price of ram headed down I would suggest a 512mb stick of 3200 if you want to overclock and later upgrades. If you are looking for stability (and want to save a little money) go with 2700.
You can easily reach 185fsb with 2700.
With the kt400 you want to run your ram and the cpu 1/1 (same speed). There is no pci/agp lock so your overclock is limited.
Do you know what version board you have?
Good luck with the new barton.
Let us know how things turn out and post any new quetions you have.
*With my vax i run pc2700( infineon)and a tbred b 2100- (stable @ 180fsb)-no increase vcore-
