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.

Is a pencil mod on this resistor possible ?

Thx a lot for your help


Here some measure points :

Sorry for URLs, I'dont have right to post it right now (not enough post)


thx for your help :ws: :ws:

Cheers,

hey there Julien, welcome to the forums :hello: , 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 :o

Thx for your edit, I didn't see it before :love:

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 :ws:

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 :o

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 :(

Pencilmod between points 5 and 9 ?
