Furmark seems to just use a lot of power draw but voltage and clocks stay the same.
Superposition clocks will drop to whatever I set them in my voltage curve. My clocks will be everywhere from 0.993V to 1.050V due to power limiting.
Below is a 1 volt challenge I did where I locked my highest clock at 1 volt, which is 2088 Mhz at 1.000v.
There's lot of power limiting so the card isn't truly running at 2088 Mhz at 1.000v. It's just running a gimped 2088 Mhz, not enough to crash. But I suspect if I had enough power draw, 2088 Mhz wouldn't be stable at 1.000v because it's not during gaming.
I am stable at 2088 Mhz @ 1.050v when gaming or running heaven benchmark with occasional Power limits which drop me to 2076 @ 1.031v-1.043v
The shunt mod should allow me to do 2127 @ 1.093v if I obtain 400 Watts of power.
But I'm afraid of running the card at 400 Watts, I'll settle for 375 Watts if that is considered safe.
I did the math, if 80% is 300 watts with the shunt mod, than 100% should get me to 375 Watts which sounds safe to me. If not then I'll settle for 350 Watts which would be 93%.
So we'll see. My CLU comes tomorrow. I already have some thermal pads, liquid electrical tape and other stuff to modify my card tomorrow. Will probably take 2 hours.
What I will need to prepare for
My card is about to receive anywhere from 50 to 75 Watts extra. That's a lot of heat. My AIO is going to get much hotter, liquid might go from 40C to 50C which is scary.
I'm going to put some thermal pads on my backplate and have some of the heat absorb and distribute out onto my backpalte.
I'm going to also apply CLU to my GPU die and protect the components around the die with liquid electrical tape.
