Need help with a voltmod for ECS 8400gs

[chatmaster]

Hi guys im trying to find out which points to use to voltmod my ECS 8400gs.
Looking for the Vmem mod and Vgpu mod.

Here is a picture of the back side of the videocard


If you could please show the Vmem and Vgpu measurement points also where to attach Variable Resistors to increase the voltages to memory and gpu.

Thanks guys

Look here, you video cards looks like a reference and is simlar to the one i have.

Still trying to find out vMem mod

[chatmaster]

There are 2 threads on the VR forum that i posted in check them out i uploaded a couple of higher res shots than i have here

[madmax999]

first of all, i apologise for bumping an old thread but i just want to help others which have the same or similar cards
no, it's not a standard card like many others

other cards have two RT9214 IC's for gpu and memory voltage regulation

but ECS 8400GS doesn't have RT9214 IC's
on the back right side of the PCB there are two IC's:

RT9218
74ACT08

in RT9218's datasheet we can see that there is just one FB pin and so that means that this is just a gpu voltage regulator

measured resistance between FB pin (pin 12) and GND (pin 3) is cca 1000 ohm's
that means that we need a 20kohm VR for voltmod

after soldering a 20kohm VR between pin 12 and pin 3 vGPU mod is done

default clocks are: 460/920/333
with 2V on GPU i can get: 940/1760/510 benchable

cooled with Thermaright HR-05 SLI/IFX
