Tutorial: How to softmod to ANY VGPU you want without hardmods! (1.3~1.6v or more)

[fornowagain]

OK, now, besides the fact that I don't really understand why you would really want to run your card at 1.55V, here's what I'm thinking.

I don't. I want to know why 1.35v is the maximum. A hardmod would take voltages higher, this method should as well.

You are simply hitting the power circuits physical limits. If the monitored data is correct, what you see is that the current actually decreases while the voltage is set to 1.55V, in comparison to 1.35V. And at the time the voltage falls back to 1.35V the current increases again.
It would seem as if the circuit just can't deliever any more current than what is available at 1.35V. That's why the current decreases when the voltage rises. You hit a point where the power output is limited to a certain amount. It's like Intel's VDroop function. Once the current draw gets too high, you either have to drop the voltage to deliever the current, or drop the current to get the voltage. Both won't happen, as it's a physical limit.
Perhaps this could be modified in some way, but I doubt that it would be very healthy for the card.

Its not hitting any limits, OCP causes instant shutdowns. There are two load states. One is as the game is running pulling the most load and the other as it idles at the desktop. If there was any current limit actuating at the higher VID-1.52v, whilst at idle there is still more current headroom. When switched to heavy 'in game' loads at the higher VID-1.52v then it could reach higher currents and crash, it doesn't. In fact the heavy load current is the same as 1.35v. Indication that 1.35v is the maximum voltage.

Oh and BTW, what is the actual DMM reading of the voltage, when VID is set to 1.55V? I didn't fully understand that just from reading your post. It's a bit confusing. But maybe that's just because English is not my native language. In one passage it reads like it was 1.35V and then you talk about 1.52V. What is the correct value?

Its in the picture as well, the actual voltage never exceeds 1.35v regardless of the VID set.


Another, you see a little variance in load depending on what the game is doing. But loads currents 1.55v=1.35v. Finally default load current @1.26v is a lot lower.
