Keep pushing it Tin! You are insane in a good way!

Have you worked more with the design ? I'm thinking on the microcontroller.

I will use ARM 32bit MCU from ATMEL (AT91SAM7S64 model).
Already have versatile modules done

Is it possible to make something like that from the scratch? useable on every card?

Tin, did anyone already said you're a f***** genious? Serious dude i'm impressed by your knowledge and dedication

sure it is possible, design of DC-DC supply for GPU is not an alien technology from Mars, it's done by humans

But it's not worth spent costs for just one unit, too expensive (only bare PCB will go near 150-200$ min for size like untouchable). I have current vga maximizers projects onhold due this.

Uhu, was thinking the same.

And what about the possibility doing it the old fashion style?

with hundreds of watts of low-voltage power (>100AMP outputs) at near MHz frequencies.

You must be joking.

I know you were using several times voltage regulation from other cards... But what is ''the best'' card for that purpose?

EVGA Untouchable special module so far is the best

To speak seriously - there is no exactly "best" thing. It's DC-DC VRD schematics. Beffy cards want huge currents and large transients. So here fit best some multiphase beffy VRM with fast PWMs (like Volterra, uPI, CHIL's etc). Less beffy cards want less power, so some 4-6phase design with nice bunch of output caps fit here maybe better. It depends on where you want to go. Ofc in general - more beffy VRD will serve you more often.
