Try setting your curve when your gpu is in the high 30s underwater or high 40s on air. You should find you may only lose 1 bin when temperature increases
This video will help for setting the curve

It's not really a mystery, it was explained awhile back on how Boost 3.0 works.

Superposition 4K, 1080Ti@2100/6000, 4790k@4800MHz: 10171 Points

Superposition 4K, 1080Ti@2100/6000, 4790k@4500MHz: 10265 Points

Funny, huh? I tried it couple times, results stay the same.

Yes thankyou I know how boost 3 works.

I was explaining your saved curve changes depending on temp in afterburner when you hit apply

You found oc your cpu hurt your score? Strange. It seems within an error of margin unless if you did this 10 on each cpu core.

I just did a 2088 Mhz @ 1.050 run for fun and got 10425 I decided to go from 2114 Mhz @ 1.075v to 2088 Mhz @ 1.050v.

4790K@ 4.7 mhz 1.312v.

I noticed for me 50deg and 65deg are the temps that I'll lose clock speed at.
I didn't understand what you meant at first but that makes more sense. Like if my temps are at 51deg+ and I save my profile then AB already recognizes that I'm down a bin due to temperature. So when I go to load that profile and I'm running at 35deg it will start me off a bin higher since AB knows it's going to get dropped when I pass 50deg.

I tested this out with Heaven running.

If I apply my profile when my temps are low before running Heaven then it jumps up a bin. If I apply the same profile after I've passed 50deg then the profile stays exactly how I had it saved.

I've been making and saving my profiles while Heaven is running. making little adjustments here and there to see if it stays stable.

4790K@ 4.7 mhz 1.312v.

I tried it three times, same results. Same for Metro benchmark. Strange, I will test more an that.


Something else:
I played around with a locked voltage at 1.093V and during a benchmark my pc shut down and restarted with a "unstable PCU warning". This is repeatable. I am pretty shure that my Seasonic Platinum 660W delivers enough power for the whole system, but I guess a shunt modded card which is locked at max voltage might draw more power in certain situations than the 6+8pin PCIe connector can deliver. When i go back to less than 1.093V this behavior does not occure anymore.

4.7Ghz is the sweet spot for my 4790k too, it is stable at around the the same voltage like yours, about 1,3V. For 4,8GHz i already need almost 1.4V.

Yeah, first time my card clocks down a few MHz is above 48°C.

So I originally purchased 4 1080 TI's- 2 Zotac and 2 EVGA's. Finally got around to testing all 4 to pick the best 2. Both Zotacs were duds, go figure.

1 of the EVGA's easily does 2100+ 500+ mem before dropping bins @ 4K while the other does 2038 with crap 250 on mem. Haven't tested/optimized any further.

Don't plan on playing around with the curve since it doesn't play well with SLI in my testing at least, single card no problem.


With OC's & tempered glass on:

52c on both cards with 100% GPU usage @ 4K hovering around 2000mhz @ 1100 rpm
46C & under on both cards with near max GPU usage @ 1440P/1080P hovering around 2025mhz @ 1100rpm


Overall, I'm pleased! Though I wish I had received 2 golden GPU's tongue.gif

Yeah I was going to say maybe your CPU was taking power from the GPU, which it likely is and your right on the limit of what PSU can deliver. Best to run a PSU at 50% load for better efficiency, so around 1000w is ideal.

My curve has everything from 1.000v+ @ 1999 and when I click apply it jumps.
1.000v - 1.025v @ 2025
1.031v+ @ 2037

It's like breaking the whole thing and then I have to manually try to pull down every spot again but when I hit apply it jumps again.
Anyone know how to fix / avoid that?


Also, is there a way to autoatically set everything to the Right of a bin to be the same thing if the one you're focused on is lower?
So lets say 1.000v is set to 1950 and everything above 1.000v is 2012 or above, but I want to set everything 1.000v+ to 2000 is there quick easy way to do that or do i have to manually click each dot and drag each one down?

That's pretty normal for it to jump, I often have to set multiple times
