You need to get a very specific resistance with Turning GPUs. If you just short the shunts the GPU goes into safe mode, locked to 300 MHz.

If you want to lift the limit as much as you can without putting the card into safe mode you need to solder. A very precise application of liquid metal has been reported to work but that is at least as much of a pain as soldering and you might not lift the power limit very much after finally getting the application light enough to avoid safe mode. I also tried silver conductive pens with no luck.

Doubling the power limit requires adding a 0.005 ohm resistor but that will put the card into safe mode. So we add a 0.008 ohm one, but this only raises the power limit by 62.5%. This means you need to add liquid metal thin enough to provide ~0.008 ohms within about two thousands of an ohm. Also liquid metal will probably change over time so the resistance might go up, lowering the power limit, or down, triggering safe mode. Then there is the liquid metal potentially dissolving the solder under the shunt causing it to fall off... which makes it so the card cannot turn on unless you resolder it.

I've had two 2080 Ti cards in my hands, and both have had pretty loud coil whine. For those that have done the shunt mod, has the coil whine gotten worse?

I really cannot suggest anything other than soldering. It's known to 100% work and stay working.

I got lucky and won the coil lottery with mine. They have never whined.

i did it

i tried with liquid metal and seems works

i insulated resistors with liquid tape, and put a very little drop of liquid metal each resistor



give a look at PL and TDP

Interestingly enough, it only really had coil when when the EK block was installed. I noticed the coil whine on my KPE card was louder with the Hydro Copper block as well. Granted, the KPE has MUCH less than the FE with or without a water block installed.

So I ordered me some 8 milliohm SMD shunts (that Panasonic one Mr. Fox used).
I already found a very detailed Gigabyte 2080Ti Xtreme PCB breakdown showing me the location of the target resistors. Seems simple enough. I would’ve gone the bios route had I found any confirmed posts that a specific bios would be 100% successful.

Is there a confirmed way to overvolt the GPU?

I’ll be back...

So much hardware left to destroy, 'accidentally'...

Anyone try the 7 mohm resistor? I'm thinking to pickup a set of 7, 8 and 3 mohms and depending on how brave I feel to rip n replace or tack on top.

Why would you try 7??? You need 3 total so either replace it with 3 or tack 8 on top. There is no use for 7.
