So we have a sensor INA3221 sensor IC (triple) in order to measure the parameters (voltage, current, power at +12V.
It using the current shunts in order to generate measurable voltage (little, but can be measured).
The graphic card control the current flow thru the Shunts.
So, the card adjust in real time the clock speed and performance to keep under specifications.
If we reduce voltage signal in the shunts (with linear dependence from current - V = Ri), will affect the power limit.
But if you use that kind of modifications, you will not provide stable, static and reliable resistance change.
Pascal are very sensible, and it has protection system to under reporting curent, and GPU can keep in low power state is reported very little resistence.
That's not the best way to improve Power Limit to the common INA3221.
You need to add fixed resistences in the 3 capacitors near the chip to do it, and you can better improve power limit.

Best wishes.

Shunt Mod . . . Is that like when a male get's the surgery to become a shemale ? I think I'll stick with regular Hard Mods

edit: my comment is simply a silly joke and in no way represents my opinion of Steve, Der8aur or Buildzoid. I have great respect for all 3 of them and what they do

GN don't know anything about electronics and physics!!!!
You are speaking about the same guy that measure T° with an IR gun on reflective surfaces claiming he is top notch thermal guy!!
What you could expect from GN aside basic stuff?!

Why not help the guy understand then? Email them, or send them a tweet. Yelling on a forum isn't helping.

I tried to help them in a constructive way, but as always in these situations where you make notice some flaws to someone, people not listen and ignore you!

I posted a lot of times on their utube video, but get ignored because putting them under bad light.

Anyway for the kind of audience that GN have this kind of stuff is more than enough, i suppose!

So yeah!

ok so i got bit nervous as this is 100th time i see this kind of "mods" presented so i went to my workshop dug around my smd resistor stash and replaced 1R0 sense resistors with 3R3 i had on my asus strix gtx1050ti , soldered few extra capacitors and in half hour i was finished.
i have tested only furmark for now but card seems to be stable enough for everyday work.

i used cheap hot air rework/soldering station and cheap usb microscope camera for pictures so sry for quality.

my point is THIS is how you change resistors right way.

furmark score after mod (sry no before) : http://www.ozone3d.net/gpudb/score.php?which=507107

also not sure is performance improved or got worse thats not point that is only matter of resistor values.

Well, in my opinion, if they intend to teach and explain something, should do it with right information.
I don't follow them, but respect the intention to bring information.
But this kind of "mod", even more for a TTV, is not properly.
Good lucky for who will follow.
We will receive one TTV and do it the right way (for what I consider).

😁
