I had the mod on only for an about hour or so total.
i used a 100k vr

just the wire to the cp or "white dot" between the two resisters shown
other to ground
stock volts 1.01v 2d 1.10v 3d
max clocks were 750ish for all 3d,no vantage tests yet was able to run 770 stock in that one

vr set 98K
here i used 1.14-15v 3d
770/1690/1230
x3 rounds of 03's 3d tests in a row
temps look ok

vr set to 91k
1.20-22v 3d
multi runs np
about .10v added
790/1769/1230

if i get some time this week i'll test it alittle more and push up the volts
i'm trying 06 now
this mod is easy 45-50mgz add on with stock h/s so far

first 06 run
782/1240 on my e8600

Wow, thats EXTENSIVE overclock. Great work!

i will do later..... when idk?

TO ADD
more finding bring me to believe that this is not a good mod point maybe,it works but it is risky .
i may have a weak card who knows? but this card does not seem to have the good hardware like the 295
i make a cap smoke with very little volts 1.25ish..i have replaced it and all is working ok.
so unless your willing to risk frying it....wait till a better point or dont bother.
