You sir, are at the end of the road with it. Lol just like everyone else.

The only other way to make more power, includes soldering, and some more in depth modification. There is a great written guide right here.

This guide does go over how to really by pass the 120% limit, and add voltage to memory, and GPU. It is not for the faint of heart. If you are not experienced, and you love your (1) and only GTX1080 you have like me, then you will not attempt this. Good luck!

Thanks for great guide. Im not good at PCB soldiering but my friends from Pratt&Whitney Co could make this - but question is - is this worth it? I dont think so but I might be wrong. Specially on air cooling - maybe Water will be better solution but still - we dont know excactly how far we can go with clocks on water or air.

Maybe better wait for some pascal bios editor?

You say you tried the Strix OC VBIOS. If it was the T4 version then there are no power limits set and also enables up to 1.2V although the curve needs to be adjusted for this. By default it flatlines at less than that. While it may give lower clock for clock performance it should still be way better than what was posted.

Have you tried an earlier driver such as 372.54?

Or perhaps it's just down clocking more than you realize. It's still a great card but something is stopping it from giving it that 'wow' benchmark scores.

There is a BIOS w/o Power limits. I can match your TS score with 200mhz lower...

Ah just saw you're not running 2350 or so in TS but 2240-50 anyway Strix T4 is not slower clock per clock than any other BIOS...

I always got the impression that it was polished as well, at least from looking at the pictures. Did you polish yours? I might just have to polish mine smile.gif

I just got a second 1080 and my regular overclock for when I only had the one card isn't working right. If I use the curve setting for the core clock in afterburner, it just always maxes out at the same core clock (1987 mhz) at a different voltage. Am I doing something wrong now that I have SLI on?

I changed the TIM and did der8auer's power limit mod for GTX1080 by shorting the resistor that's the closest to the 8-pin PEG connector.
As result I don't even have to touch the power limit in XOC/Afterburner anymore and the card boosts to 2012MHz (1080SC ACX)

GPU-Z now reports up to 55-57% TDP under FurMark.

There seems to be a side effect to this mod - GPU-Z reports a lot of Pwr perfcap when the card is idling. I haven't noticed any suspicious behaviour yet.

I don't think the mod was really worth it, my top OC remained unchanged at around 2050MHz. I'd have to try the Strix BIOS again to see if I can push the voltage higher than the stock maximum of 1.093v.

I did exactly the same. 1080 shunt mod + EK WB :

What is it?
Highly doubt 1440p dx12 benchmark can be CPU limited...you can try FS Ultra @4k should be no difference comparing GPU scores from Celeron to I7
