oh its only HALF the discussion. before it was how much or what the 6 pin connector from the PSU could do. now its about the 6 pin on the card.
so please allow me to get yo up to speed.
people are freaking out about the sense pin being grounded. well i ran across a reddit post
(maybe need a salt shaker?)
The same spec says that the implementation of Sense is to have it connect to GND in the PSU or connector.
The idea would be that you design a circuit that measures if Sense is either high resistance (no connector) or GND (connector plugged).
There is nothing that prohibits you from using the Sense Pin as a real GND source. You would just have to gather the information if a connector is plugged otherwise and not by comparing Sense to GND, which isn't really a big deal to handle in another way.
so how would it gather information? well since half the vrms are pci-e and the other half the 6 pin.Actually Hardcore Overclocking - The road to voltage Fury.
The first thing I learned about the IR 3567B is that it's pretty smart. So smart, that the damn thing will not let the card run if it doesn't sense current on the VRM phases. With most GPU voltage controllers you cut the power sensing lines and they just ignore the fact that the current reading of 0.8A is wrong and continue running the VRM like nothing's changed. Not the IR 3567B, no the IR 3567B shuts the card down if it sense 0A on the phases.
the ironic part is that blog is the same guy who started this sense pin ground thing as out of spec in his twitch stream.Edited by looniam - 7/6/16 at 6:49pm
