Gigabye EP31-DS3L/EP35-DS3L vdroop pencil mod

[regenade]

Actually I have gt an EP31-DS3L a few days back and was fighting with it to get to 3.6Ghz stable on my Q6600 and the huge vdroop was a big downer :(

Now bumped into the OC forums thread and found that no solution is yet available for the ISL 6334 based EP35-DS3L and EP31-DS3L....looked into the mod pics of the vanilla P35-DS3L and the usual spec sheets of the ISL 6312 (old) and ISL 6334(new).Had some high resolution shots of my mobo , and so figured out the pencil mod :)....I knew it could be hit and miss but still went on and tried it. Bingo and I was 100% correct on finding the correct resistor and its working 100%

Here the pic and explanation of the mod

About the Results here it is :

Q6600 @ 3.6Ghz
Pre Pencil mod :

Bios --- 1.5375 V
Idle --- 1.49V
Load(OCCT 4 cores) --- 1.42V

Post Pencil mod

Bios --- 1.48 V
Idle --- 1.44V
Load(OCCT 4 cores) --- 1.41V

Hope this helps :)

Oh and ya thnx to all the blokes@OCforums for the original P35-DS3L mod w/o which this wouldn't have been possible :)

Excellent i have been searching for this mod i cant get stable over 3.4 with my E6850 for anything, tomorrow i will give this a try and post back

Ok this worked well, after finding a pencil with good conductivity ( Menards carpenter pencil ) i managed to get a reading of just over 1000 ohms from my original 1786 ohm reading with my trusty snap on multimeter and fluctuations and much of the droop has vanished.:woot:

Yea i know i said tomorrow but i just could not wait but im glad this issue is resolved now i can get some sleep and try my hand at some better clocks when i have some time on my hands.

Thanks regenade for the good post.:up:

Maybe someone can chime in on a hard-mod in the future for those who prefer to do minor adjusting to make things a little more tweakable.;)

NP...welcome :)
Actually I had to go down to as much as 750Ohms finally to get only 0.02V droop on load with my Q6600
