fsb and dram ratio?

can you help me with this cpu fsb and dram ratio settings what is this and how should i set it i have an asus a7n8x and theres no such settings.

thanks

and on this board is the agp and pci locked? and if so than i dont have to mess with the fsb and dram ratio thing right?

Yes, the PCI/AGP is locked, all Nforce boards are. You don't have to change the ratio. I don't understand exactly if you have an Asus board, shouldn't you be posting in the Asus forum? Anyways, most people with an NF7 change CPU interface to enabled and the ratio to 1:1 which equals anything such as 3:3, 4:4 or 6:6 etc if they are going to overclock the board.
