Default Needs GA-G33M-DS2R VDroop mod (ISL6327)

Hi

My name is julien, i'm from France and i'm new on this board.
I'm new in Vmodding but I need a mod for my Gigabyte GA-G3MM-DS2R with a quite big Vdroop and Vdrop.

The voltage regulation chip is the same as P35 one, an ISL6327

I ve measured many resistances and i think i ve found the FB resistor that causes Droop, it s a 2.6k resistor between VDiff & FB.

http://fishton.free.fr/IMG_0175.JPG here is a very HQ photo of the layout

Is a pencil mod on this resistor possible ?

Thx a lot for your help


Here some measure points :

thx for your help

Cheers,

fishton

hey there Julien, welcome to the forums , fixed your post count, pics and URL will work now, sorry for that, it's to prevent spam bots from messing with our forums

Hope somebody will help you out, unfortunately VMODs are not my strong point

Thx for your welcome

I understand why url are not allowed, that's not a problem, except for guys who don't know how to replace "*" by "t", but these guys will not be able to make a Vmod, i'm quite sure

First of all, I'm not 100% sure of this mod. You should wait for someone to check this.

1) Make sure the markings I made are corect. Check whether both points 1 are ground.

2) Are you sure point 6 shouldn't be point 9 on your drawing? That would make much more sense.

Hi

Big Thx u for your response

I m quite sure for the points, but i ll verify tonight because I think I forgot some other points connected to Comp.

For the VDroop, the pencil mod will shortcut the 2.6k resistor and VDroop will be null ? am i right ? but I don't understand why putting a 500k resistor accross is equals to pencil mod

If I just want a vdroop mod (no vcore mod needed for instance because I don't want to solder on it right now), I just need to pencil the resistor ?

No the pencil mod I indicated is also for vcore.

I haven't figured the vdroop mod out yet

I thought pencil mod on resistor 2.6k was enough for Vdroop mod
