Not yet. I've been working on some other things. Still plan on it though.

Hi. Shouldn't just lowering the resistance between VDROOP and VSEN(Rfb) do the job?

According to the datasheet this resistor determines the voltage droop:

Vcore = VID - Idroop * Rfb

Offset pin didn't seem to do anything.

Can't seem to find a connecting resistor between vdroop and vsen. frown.gif

Pizza, take a look at this mod guide, it uses a similiar IC(L6714) and might help you too:

Btw, do you have any pics of the IC area?

Yea, looks like mine will be something similar.

Seems like its gonna be right in this area.. check and see if pin 4 and 5 are shorted together first.

4 and 5 are not shorted together. There's a .985K resistance between them.


Measured and labeled the area. Think I found it a bit to the right. Ran out of room so I used a 2nd pic. Should I shade th resisitor between 4 and 5?

Yes..the datasheet says to short 4->5 to implement vdroop function..I am assuming this means to disable droop. It may not be the fix you are looking for but may help at least show us whats next for this ...
