How much difference with divider

[Gaygle]

Hi i was wondering how much difference is there in performance if i run my memory with a divider. i currently have it at 215mhz 2:1 but when i had it on a divider before, i had the CPU up to 235mhz (from a 3500+ newcastle and still had more) and 186mhz from the memory at 2.5-3-3-7.

any help is welcome

thanks
