One may argue that this is dangerous, pointless, or that there are better/less permanent methods. Sure. But, I like some danger and challenge. The modification as advertised:  The modification in practice:   I found it to be a very easy modification. I have soldered much harder; and I am no professional. Before, my vanilla 1080 was consistently hitting the 120% power limit. After, I haven't seen it detect greater than approximately 85% power. It is hitting no limits now. Now, I am only up against silicon lottery. Before, my max core clock was 2100 MHz and it periodically dropped to 2086 or lower as it bounced up against the power limit. Now that I am not hitting the power limit, my max core clock is 2139 MHz and it stays there solidly without budging. At 2152 MHz, I start to get artifacts. So, a 2.5% core clock increase. Will it equal a 2.5% performance increase? No; only a 0.4% performance increase according to Superposition benchmark. Oh well. ;) Before:  After:  I did it so that you don't have to. I hope that I satisfied any curiosity and that you enjoyed this post.

I did close to the same, but no solder was involved and it is fully correctable. I do see the power limit hit 98 at absolute max loads and heavy overclocks, but it isn’t enough to hurt anything. In the past, the card would hit the power limit in TimeSpy Extreme Graphics Test 2, but now it doesn’t fluctuate unless the temps get over 40c.

I was quite aware of the liquid metal method, but I wanted to try something different and less common. Certainly I wouldn't advise others to do the same.

How long did it end up taking you?
Also, I wasn’t talking your work down or anything. It’s actually extremely clean. If you get a solder sucker, you could probably remove the caps off the top, and trim down the excess to undo that work.

The actual soldering part only took a few minutes. The whole thing took over an hour due to draining the loop, taking the card out, removing the waterblock, applying the mod, and then building it back up.

I think the draining and waiting to refill is the only thing that bothers me about watercooling these days, lol.
Thank you for sharing. It’s good to see someone taking the time and chances for things like this.

the_Scarlet_one did you do the same 3 with the liquid metal?

I am pretty sure that the liquid metal method is to apply liquid metal to the top of the current shunt resistors (the big things which say "_M0" or "R00_" on top of them) instead of being applied to the top of the capacitors located next to the current sense chip (the things which I messed with). In other words, I think the answer to your question is "no". Sajin
You can find current shunts which are marked *RS1, RS2, RS3* on PCB with black resistive element in center and often with R002 or R005 or 2M0/5M0 mark on top. Sometimes there are no marks, but look is always very similar, like a large rectangular flat part with two or four wide metal terminals. Usually these shunts are located very close to input power connectors before the main VRM circuitry. If we manage to reduce voltage signal (which is in linear dependance from current) from these shunts, then reported power limit will be reduced as well. ...

Nope, not the same spots, just like tyger said. You see the 5M0 shunt resistor in the bottom left of the image right next to the fan header? The liquid metal goes on the three of those that tyger linked.

Thank you ty_ger07 for the clarification. As I read your last post I recalled that it was the shunt I had read about with the LM and not the caps as you pointed out. I do not yet own a 1080 myself but have been trying to keep an eye on what peeps are doing. I am planing on the FTW 3 Hydrocopper - which should be a good candidate for a good tweaking And TY the_Scarlet_one for the reply as well

Wow.
That was a nice mod Tyger
Thanks for sharing this. Thumbs up to you bro! (wish I would have those soldering skills to do the same)

Thank you! It was realy quite easy. I didn't use a magnifying glass or a tweezers or anything fancy. Just a dab of flux on top of each capacitor, layed the resistors on top of the flux, tinned the soldering iron tip with a little extra gob, and brushed the tip of the soldering iron against each resistor for a second or two, one side at a time; kind of like using a reflow method. Looking at the pictures on my phone, zoomed in, I see that I could have given a couple a little more love.

Nah man
my soldering skills are 0.
Potato skills in other words.
I need to try to adventure on soldering sometime. Specially small solderings like this.
Still, amazing skill Tyger. Congrats on your mod man.
