NF7-S2G multiplier

Does anyone know how to change the multiplier on an NF7-S2G. I just bought one and when I put my Mobile Barton XP2600+ in it, it sets the CPU to 7x multiplier and there is no way to increase it in the bios... I don't want to physically mod my cpu to lock the multiplier, so is there any way to change the multiplier or any modded bioses around to do the trick?

Need it because my Epox 8RDA+ V2.1 board maxes out on 1.85V VCore...

You can't change it, forget about this mobo. It's a holy peace of crap!
Get an old NF7-S, that rocks!
