This is obviously not your normal section in a review but hey, this isn't a review dammit. It is my idea of a fancy information and results thread. At this point, all of the volt mods for this board aren't really 100% confirmed but that is simply because I am a little busy with all kinds of things so I haven't tested them all. As time goes by and I get off my butt and test the mods, I will post them here. Until then, feel free to hit up Dinos22s thread over here where there is a bit of a start on all the vmods for this board including what I don't have posted here.
vDROOP
It was posted that a 50k ohm VR was needed for this mod so that is what I used but you could likely use a 20K or even 10K ohm VR without issue as it is tuned to almost 0 resistance to eliminate vDROOP. As it stands, tuning the circuit down to about 600 ohm did the trick to stabilize the vCORE from idle to load. I could also lower resistance even more and raise vCORE at idle and load from what is initially set. You will want really small gauge wire because this one is a tight solder. Rookies need not apply.

vCORE
I started this out thinking 100K ohms was necessary but a 50K ohm VR is perfect. So please excuse the second 50K ohm VR in the photo that I ran in-line as it wasn't necessary and later removed. This one is very straight forward and the capacitor we solder to is an 0805 so decent size. It is pretty easy compared to the vDROOP mod. You can use any ground, I have used the ground pad of the un-populated transistor behind the CPU fan header.

vSPP
Dinos22 post was again bang on and the soldering point was correct. Measured resistance of the circuit was 776 ohms so I went with a 20K ohm resistor. After the mod, resistance dropped to 745 ohms and voltage was 0.06v higher than selected according to the BIOS monitor. I still don't have a confirmed vSPP read point on the board so I am just going with the BIOS reading as it raises with lowered resistance. Very easy to solder to the IC leg and a perfect mounting point, as seen, alongside the I/O tower. The vSPP mod has definitely helped with FSB clocking and memory clocks but additional cooling is required.
