And nearly none if you can't oc that high.

Can you show yuor curve?

Also higher core doesn't mean better performance as it was proven here few times. Many times higher clccks on higher V will give you worse performance/fps/score than lower clocks at lower V.

If it was as simple as power limit it would be nice smile.gif


It's all a silicaon lottery as always smile.gif

Thing is, the power budget on the damn Aorus is so ridiculously overkill that I find I'm permanently capped by Vrel or temperature (the bins above 40 degrees) more than anything. I'm still looking for something that can max the Power limit, so far its looking extremely difficult unless I do voltage hardmods.

Its the same as my old GTX 980ti with the unlocked BIOS, not so much about absolute best performance but pure consistency in all scenarios.

Can you post your curve? Where are you max and when it downcklocks.

It's true that the quality of the chip matters. It might be true that it's such a big factor it outweighs all else. But it's also true that a great FE card would be faster with the right power target for example.

Maybe like 1.5% in the most.

Yeah for superposition benchmark specifically.

But in the great majority of games, like 0.5%. Games don't run you to the roof with power draw during the entire duration of the game. My card will do Witcher 3 at 2088 Mhz and not drop due to power 95% of the time.

That small fraction of 5% I'll drop to 2075 or 2063. So you can say that it'd probably make a 0.05% difference in performance even if you compared the average fps.

This is what makes me resist doing the shunt mod, it'll be all this effort and money for tiny gains. It would have been worth to do it when I installed my AIO initially, but I don't know if it's worth doing now.

Just installed my Accelero Hybrid III-140 on my 1080 ti fe. I don't have any VRM cooling yet (just a fan blowing on them devil.gif ). I ran 2075 the whole time, my max temp was only 47C! I plan on doing the shunt mod once I get some VRM cooling.

Did your clocks change at all once you went hybrid?

I'm curious why did you choose this instead of just mounting a AIO directly into the FE shroud and keep the oem midplate to cool the vram and vrm?

Here's to hoping there is a way to turn of this regulator that kicks it down to 300 Watts

If you look at the text there it'll give you some idea as to why - NVidia's power level sampling is relatively slow. 119 samples over 2.47 seconds. In most cases that's even slower than your framerate, so it takes anywhere from 1-10 frames for it to figure out that you've exceeded the power cap and then take action to reduce clocks, frequency, power gate (turn off) functional units temporarily, or do whatever it does to keep you below the limit.

Because of this there will always be situations where you 'peak' well above the limit, and this is to be expected. It will try to keep the average < 300w though.

Hey all, if i run timespy demo and it locks up midway, does it mean my OC is at the limit?

Im on FE and it barely go past 2ghz before it lock up. I am afraid i got the worst luck in GPU lottery again.
