P5N-E Vdroop Kobalt. Mar 19th, 07, 02:41 AM 1 links from elsewhere to this Post. Click to view. #1 (permalink)
I followed the vdroop mod pictured below except with a pencil, which others have had success with. However, I still get around .02vdroop and was hoping to bring that closer to .005-.01v as others have done. Any ideas?

Here is my data (original resistance was 129.5k ohms and all voltages are measured with a DMM)
1.343v idle 82.7k ohms
1.283v load 82.7k ohms
.06vdroop

1.345v idle 77.6k ohms
1.285v load 77.6k ohms
.06vdroop

1.350v idle 66.7k ohms
1.295v load 66.7k ohms
.055vdroop

1.351v idle 57.3k ohms
1.307v load 57.3k ohms
.044vdroop

1.3431v idle 41.6k ohms
1.310v load 41.6k ohms
.033vdroop

1.361v idle 31.5k ohms
1.328v load 31.5k ohms
.033vdroop

1.362v idle 27.6k ohms
1.331v load 27.6k ohms
.031vdroop

1.356v idle 20.7k ohms
1.330v load 20.7k ohms
.026vdroop

1.348v idle 14.9k ohms
1.327v load 14.9k ohms
.021vdroop

1.348v idle 12.4k ohms
1.327v load 12.4k ohms
.021vdroop

1.357v idle 9.75k ohms
1.338v load 9.75k ohms
.019vdroop

i have modded several of these boards. you need to use resistors or pots, pencil is not good enough.

look in these forums, or on xteremesystems.org in their vmod section, you will find what you need.

I'm not even going to attempt to solder something on an area that small and crowded...i suck at soldering .

I'm confused what the difference between pencil and actual resistors though. Don't both decrease the resistance to the same level? Why are pots/resistors better (besides cleanliness or longevity of the mod)?

with a conductive ink pen ("pencil") - you do not adjust the resistance, just alter the flow of current.

with resistors/pots,etc - you change the resistance for a desired effect.
