ASUS A7N8X-E Deluxe,You can’t increase the voltage on the chipset North Bridge ?
ASUS A7N8X-E Deluxe,You can’t increase the voltage on the chipset North Bridge ? Has this be changed in the bios updates ?, just saw a review and this states the best overclock you could get was 225 ? Must be a simple thing to do to add right ? Thanks. |
Is this a common option in bios's ? |

The Uber 1007 BIOS I have does have that option (I think), but it doesn't work. It needs to be wired into the motherboard and Asus didn't do that.

Ben Pretty sure that is true, did read the same in the release notes for UBER 1007. Option is there, but dosn't work till you have hard wired the mod. From all my overclocking here, it seems it is that way (A7N8X-D 1.04 and now a V2.00 M/B) as it hasn't helped at all just changing the BIOS setings for it. Minotaur (8* |

I think I heard that it doesn't work from various posts on nForcersHQ. Never really tested it myself.

Ben If you are referring to this mod: http://www.nforcershq.com/forum/viewtopic.php?t=9237 the CM3708 has no programmable options. You could tie a GPIO pin from one of the motherboard chips, to a resistor divider network on the Vref pin, which could be used to give you two programmable voltage values. So, it can be made adjustable, but from the mobo manufacturers point of view, if the Vreg had been designed properly in the first place, there wouldn't be any need to mod it or overvolt it. The problem was, the circuit undervolts unintentionally, and this should have been fixed on later boards. The datasheet for the CM3708 is he http://www.champion-micro.com/datash...ice/CM3708.pdf On page 6 of the datasheet, L1-C1-C2 is the filter network on the output side of the regulator (being chinese, they drew the schematic backwards :-). On the A7N8X-E, these components are likely to be the coil and cap near the right hand end of the AGP slot. Maybe someone who owns both older and newer versions of the board, could measure the voltage at the output filter, and prove this has been fixed. Paul |
