Sorry about thread hijack, but I found my own way to vmod GTX 285 :-D



So final "modifications" list

Stock VRM:

* VID Vgpu to 1.55V
* Vgpu VRM OVP adjusted
* Vgpu VRM OCP total adjusted
* Vgpu VRM Added capacitors
* Vmemory EN signal assertion NPN removed
* Monitoring chip FAULT pins disconnected from VGA PCB
* Vmemory VRM Vout adjusted by VR

But in the end stock VRM was totally disconnected from card

Extra VRM:

* EVGA The Untouchables board (700+ RAW power, 10channel Volterra VRM + 3channel DrMOS based 100AMP+ VRM)
* Digital controller for setting necessary volts for power
* Lots of thick wires
* Lots of extra tantalum and alu LowESR caps on VGA PCB

5 PCI-E power connectors



Moar mods...



Just pretesting



This with 900MHz GPU and flying high memory 1440MHz BOTH with GPU! Not possible earlier with stock VRM on this card even with -160°C.

Tin. It's so awesome to have you over here. I still gotta order my caps. If I post up some pics will you explain for me and everybody to know why/where to apply them? Also, you care to share your vmem mod? Measuring with DMM the VR suggested isn't rated high enough. Plus I'm wondering if you found an alternate mod spot.

That looks like Master Shammys little board wired up to that puppy, so that right there may make it difficult for us to duplicate absolutely ingenious work and an awesome job of wiring though

Ok, my eyes just fell out of my head.... I want one of those boards. Will it work with any evga card, or is it proprietary to the 285?

It will work with any card, or should. Plus it works with evbot.
