I actually got this board by accident and wanted the P5E3 DLX, but ah well...
I figured id give this board a try for now.

I dont know how to find mods myself, so I figured id go ahead and at least post some pics and find all the spots to measure the voltages from.

Soldering on the front is a bit annoying and some spots are really hard to get to without taking the heatsink solution off and even then its annoying, so i just went ahead and tracked all the voltages at the back of the board where soldering takes seconds

Take all of this with a grain of salt, dont blame me for killing your hardware yadda yadda etc :P

nb gtl for doesnt change when setting a different nb gtl multiplier in BIOS, but it does track with vfs/vtt... so i suspect the board actually doesnt have a nb gtl setting, at least not a working one :/

Here are all the reading points for:

Vcore
CPU GTL
PLL voltage
Vfsb/VTT
vMCH
NB GTL
vFSB "swing"
Vdimm
Vdimm VTT

have fun
