ASUS P5N32-SLI SE Deluxe Pencil Voltage Mods
ASUS P5N32 SLI SE Deluxe is basically identical to its predecessor, the P5N32 SLI Deluxe, which are both based on the NVIDIA nForce4 SLI x 16 chipset. It just switched out a CPU voltage regulator for one supporting VRD 11 to run the latest Intel Core 2 Duo Processors. And also did away with the power molex connector in the awkard position right below the first PCIE slot. An old dog, learning just one more new trick. Now those of you overclocking on this board may be interested in the voltage mods for it, most of which can be accomplished with a simple pencil as well.
Below you see the MOSFET Legs to measure the SouthBridge Voltage (VSB) and Memory Voltage from::
Default VSB is 1.5v and default VMem is 1.85v.
At the same area, mod VFSB, VSB and VMem as seen below:
To increase VFSB, solder a 20K Ohms Variable Resistor to the point marked above, set at maximum resistance, with the other leg of VR connected to Ground. Reduce Resistance to increase voltage. Alternatively, pencil the resistor in the green box to increase voltage. Go down slowly, about 20 ohms at a time, to increase voltage.
To increase VSB, solder a 20K Ohms Variable Resistor to the point marked above, set at maximum resistance, with the other leg of VR connected to Ground. Reduce Resistance to increase voltage. Alternatively, pencil the resistor in the green box to increase voltage. Go down slowly, about 20 ohms at a time, to increase voltage.
To increase VMem, solder a 10K Ohms Variable Resistor to the point marked above, set at maximum resistance, with the other leg of VR connected to Ground. Reduce Resistance to increase voltage. Alternatively, pencil the resistor in the green box to increase voltage. Go down slowly, about 20 ohms at a time, to increase voltage.
Finally we come to the CPU Core Voltage Mod. Those using extreme cooling may want more vCore than the BIOS allows.
To increase vCore, solder a 20K Ohms Variable Resistor to the point marked above, set at maximum resistance, with the other leg of VR connected to Ground. Reduce Resistance to increase voltage. You can monitor voltage in the BIOS hardware health monitor.
