Help voltmoding a realy old motherboard

[andlcs]

Hello,

I want to voltmod the Vcore of the ASUS P3V4X motherboard. I can set until 2.0V+ in BIOS but no matter what I set the Vcore doesn't change from 1.65V. So, I think I need a volt mod. . .

System Specs:
Intel Pentium 3 700MHz/100MHz BUS Coppermine Slot 1 Stepping A2 1.65V
ASUS P3V4X
128MB PC133 RAM
I need few more volts to get 933MHz (133MHz BUS).

The big IC near the parallel port which I belive is the one to mod is HIP6021ACB:
Datasheet: http://www.intersil.com/data/fn/fn4793.pdf

There's another IC between CPU slot and RAM slots, near a choke:
HIP6013CB, Datasheet: http://www.intersil.com/data/fn/fn4325.pdf

And on the corner near the memory slots: one LM358M and one LM431.

Thank You.



Voltage readings of HIP6021ACB:

VID04 = 0V
VID03 = 3,3V
VID02 = 0V
VID01 = 0V
VID00 = 0V

VSEN1 = 0V
VSEN2 = 3.3V
VSEN3 = 0V
VSEN4 = 1.3V

FB = 0V

1) In this case connecting a VR to FB pin and GND won't work?



In the IC datasheet there's a table of the VID pins:
VID4/3/2/1/0
0/1/0/0/0 = 1.65V
0/0/1/1/1 = 1.70V
0/0/1/1/0 = 1.75V

Where:
0 = Connected to GND
1 = Open or connected to 5V through pull-up resistors.

2) If I connect +5V from PSU to VID0, VID1 and VID2 and connect VID3 to GND will I get 1.7Vcore? Or I need to lift the pins from pad (disconnect then)?

3) Is there any way to "pin mod" Slot 1/SECC2 processors like we did w/ the Socket 462 processors?
