Does anyone know what bios for the MSI K7 turbo has 1.85volts setting in it??

Hey guys does any know where I can get a performance or overclockers bios for this board. I have a duron 800 and the lowest multiplier that I can go is 8 and I would really like to go lower. I am not sure if the mobo doesn't allow this or is it just the bios that I have. I have the newest bios that is out from the msi website. Thanks and please lmk what you guys think.
