Asmodian I do, except for power virus loads (e.g. furmark) where you would probably want it to throttle it anyway.

So, yes, replacing the 5 mOhm resistor with a 3 mOhm one will add +66.67% to the power limit relative to stock.
So about 415W max in real even if gpuz reports less... do you think it will be enough for dont hit again power limit at stock frequencies?

Replacing 5mohm with 3mohm should give me +66% about 415W can someone confirm this ?

How do you do the math that you get 100% more power by cutting resistance by 50%?
Using V = I*R and knowing V is the constant:

I1 * R = I2 * R / 2
I1 * R * 2 = I2 * R
I1 * 2 = I2

The way I do the math, if stock is calibrated for 5 mOhm, and you lower resistance by 50% to 2.5mOhm, then power would go up by 50%.

Starting with 5mOhm stock value.
50%, to decimal, is 0.5.
0.5 * 5 = 2.5.
So 2.5 mOhm, would be 50% less.
50% less resistance, means 50% more power.

And if 2.5 is 50%, then having more than 2.5 would have to be less than 50%, not more.

If you are replacing the 5's with 3's, wouldnt that give you 40~% more power limit?

This operation will give me a +66% power limit , so 250W + 66% it's around 415W correct? Do you think it will be enough or i need more? I dont plan to overclock the card, I just want remove power limit for stardard boost (around 1860Mhz if I remeber correctly).

Harry Hecate Hi, weren't the Titan Xp have some missing mosfets?

Honestly I wouldn't do it myself. The VRM cooling would worry me and they already get pretty hot with the blower coolers. The power/heat for performance trade off due to this mod is not great, Nvidia can save a surprising amount of power/heat without hurting performance too much

If you don't go crazy with the overclock, or especially voltage, it would be fine; no fires or anything. Just not really worth it.

chibi How feasible is it to run the shunt mod on the stock air cooler? Blower style for the Titan Xp. I have my blocks disassembled right now and not sure I want to go back to watercooling for the time being. Getting tired of the yearly maintenance lol.
