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



In theory

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.

So I did a Unigine Superposition 1080p Extreme at 1.075 v 2088 core and had zero power limiting.

Thx man, but looking at the logs you know what I'm thinking smile.gif

Anything over the magic 111% on Asus is probably where you start limiting?

Time Spy GPU test 2 is very power demanding, that's why are clocks jumping so much during it. It is actually the 2nd most power demanding test i know, 1st is Furmark.

Yeah, but if my power curve is in a straight line above 1.000v no way it should jump to 1.062v. Should max out at 1.000v. frown.gif

Can you test the stock mod with your same voltage curve?

When I had the ASUS bios, **** jumped everywhere and anywhere for some reason. It was doing clocks and voltages I didn't even have on my curve. But the stock bios seems to lock clocks and follow my voltage curve better.

Superposition and Timespy follow this voltage curve very closely, I don't see it deviate much.

My 1.000v challenge.

TimeSpy test two at 1999 core, .950v does the same thing, voltages jumping around, going to 1.062v as the Asus BIOS. And seems to power limit a tiny bit even at .950v. I got the same results at 2037 core 1.000v on Asus BIOS, exactly the same. redface.gif

Why have we not thought about testing the inno 3d 1080 Ti bios?

It has a reference design but pushes 50 more watts!

This might be the key to our power limiting issues!

Are the EVGA FTW3 or Classified out yet? And if it is, can someone do a nvflash64 --save ftw3.rom in an admin command prompt so I can test it?

The new gpu-z let's you save the bios put now I think.

But our best bet might be the Inno3d, it's a 8+6 pin card, has generally a reference pcb design and pulls 30-50 more watts I believe.
