Slotkey vs MB voltage jumpers?

[tinkerboy]

I am planning to buy a slot1 MB with lots of voltage settings. I also am planning to us a slotkey to run a socket 370 celeron in it and possibly overclock it. Question is- some of the slotkeys I see for sale have voltage adjustments on them. Are these jumpers redundant if I have a MB with lots of adjustments? Could I have problems having the ability to adjust v in both MB and slotkey? If I get adjustments in both places which one should I use to set the voltage? If I have a MB with many v adjustments should I buy a cheapo slotkey with no adjustments? Thanks for any answers.

Buy an Iwill slotketII converter card.Reason:It will handle any PPGA/FCPGA CPU.The new Coppermine 500E/550E is a hot item right now, for it will OC to 650-800+,but you must have a mobo or converter card that will go down to 1.6volts for it to work......DawgTuff.
