If this damages anything I my self and ocforums is in no way responsible for this. This will also void your warranty.


This mod is for the GA-965P-DS3 rev. 2.0 and has been tested by myself and confirmed to be working however it may work on the 3.0 but its not tested. This will not work on a Rev. 1.0 for that you will need to visit this (http://sg.vr-zone.com/articles/Gigabyte_GA_965P_DS3_Core_2_Motherboard_(Pencil_Mo ds)/3870-9.html) site


Required

-Pencil
-Desire to reduce or elimeliminateoop

Optional

-Soldering Iron
-Solder


Optional

-Conductive pen


This mod is pretty simple. Useing the method you chosen "I picked a good old number 2 pencil" You need to shade the resistor outlined in red in the image below. This is located to the upper left of your first Ram slot.

Sorry for the poor image but i had to use my eye toy webcam. you can see what needs to be done.


Results useing a Q6600 at 3.25ghz


Stock unmodded

Idle Load
1.264 1.232

VDroop 0.032

Modded with pencil

Idle Load
1.280 1.264

VDroop 0.016


Update Oc'ed it a little more for test and shaded it a little more and here are the results

Bios voltage 1.456

CPUZ shows

idle Load
1.424 1.424





All load test were done with prime.



If you use a pencil and you still get some droop. Simply shade the resistor a little more and try again. After a few shadeings i got it got rid of the droop.


Further test results


Mod done with Defogger repair kit copper stuff. Just painted on the resistor.

Idle Load
1.280 1.280 - 1.296


The load would spike every now and them from 1.280 to 1.296. This method offered a higher idle and load voltage than the pencil method but the pencil method i done was rock sold stable at 1.264.

No. This only works on GA-965P-DS3 Rev. 2.0 and maybe 3.0 if they dident change the layout that much what i think they dident.
