Want to improve overclocking? Well here are some instructions on simple voltage mods you can perform on this board to push it even further. Take Note that such mods will void your warranty immediately! And that risk is involved!

For almost no voltage droop between idle and load conditions, a CPU voltage droop mod can be performed.

Directly short out the resistor circled above, with a conductive pen or a tiny blob of solder. Before the mod, I would get about about a 0.05v droop under load, but after the mod, the CPU voltage remained stable throughout.

My friend Kunaak has figured out some useful voltage mods for this board so here are some information die-hard overclockers will appreciate.

First off, you can modify the VMCH voltage, that is the Northbridge voltage for the 965P chipset. This may help you out in achieving higher FSBs. Be sure to cool the chipset well though, with at least a fan over the Northbridge heatsink.

Above, you see where to measure current VMCH with your multimeter, which is right below the PCIE x16 slot.

Now under default voltage, VMCH should read about 1.2v. You can solder a 20K ohms Variable Resistor from the leg of the chip arrowed above and connect the other leg of the VR to ground. At maximum resistance of 20K ohms you should get about a +0.03v increase. Lower resistance to increase voltage. For those afraid to solder, you can actually pencil shade the resistor circled above to increase voltage alternatively. The original resistance of the pin arrowed should read about 656 ohms. Shading the resistor such that the pin reads 630 ohms will give you a +0.1v boost. Proceed from this linearly, but always measure resistance before powering up the PC so that you don't overvolt!

Memory Voltage for this board goes up to 2.4v selectable from BIOS. Very decent allowance, but there are some who love to feed even higher voltages to their Memory when they find those that scale well.

So, read your current Memory Voltage from the spot on the MOSFET marked above. This is located beside the PCIE x16 slot. You can solder a 20K Ohms Variable Resistor to the pin arrowed, connecting the other leg of VR to ground to increase the Memory voltage. Set at Maximum of 20K ohms, you get a 0.06v boost upwards. Tune down resistance further to increase voltage. Alternatively, you can also pencil shade the resistor marked above. Resistance of the pin arrowed should read about 900 ohms. Pencil the resistor such that the pin reads 880 ohms should give you a +0.1v increase. Proceed from this linearly, but always measure resistance before powering up the PC so that you don't overvolt!
