My memory at default voltage 1.6v would do 7900Mhz with 1.61v I could get 8020Mhz I am afraid to push with no heat sinks but it is not an option with my raystorm blocks in the way.
I was just thinking why I took the resistor off like I did, I wasn't sure if I was removing the right one so I thought I would risk it and leave it possible to put it back on just in case the 680 guide I followed was wrong as it didn't have any results after the mod and one of the senior moderators at the ROG forums wasn't sure either.
BTW MSI AF for core speed
I measured my memory voltage just now, without any overvolt method I have 1.621v while benching on valley, that was at stock clock and then also with oc. While i only have the gpu core set for the overvolt mod, I flipped the switch and it did not effect the memory at all as expected. Im curious what your memory voltage really is if measured at the test point. Kinda funny how this software isnt reading actual but rather off of some predetermined calculation of what it "should" be.
Im using a fluke 88 V so its a decent meter.

If you can figure out how to read and write to the PMBus then you can do some cool stuff like load line calibration, current limit and offset voltagehttp://pdf1.alldatasheet.com/datasheet-pdf/view/315613/ONSEMI/NCP4208.html
maybe the command line could be "msiafterburner /ri0,40,de" and see if it gives you 51 (default load line) probably a bit complicated for most but no point wasting info.
Im not much of a software guy but if you wanna explain a bit I wouldnt mind trying some things out
Here are some things I found, I just dont know if it can help?
Searched ASP1212 (found printed on chip) and found some sort of data sheet
One reviewer on techpowerup seemed hardware savy and stated the chip is rebranded but looks like one from uPI
ASUS is using a different voltage controller than the reference design. Since it has been rebranded, we are not exactly sure what model it is, but it looks like one from uPI.
