How To Set Dram Bank Enterleave Setting In Motherboard Bios/

Hello! i'm new here and was just wondering, I have an ECS P4VMM2 V7.3
MOTHERBOARD in my pc and, the online manual says to enable this setting.
on my bios screen it gives me the option of disabled/2 way or 4 way? i'm
running two sticks of Kingston DDR 512 mb. pc 2700/333. anyone know what
the two way or four way settings are for and, should I be using one of
these settings instead of disabled? Thanks for any advice!
:confused:
