Following the method here: http://www.overclock.net/t/1627212/how-to-flash-strix-1080-ti-bios-in-an-1080-ti-fe

And my card is now an Extreme. biggrin.gifthumb.gif

+150 now available in AB, and default memory clock is now 1404MHz instead of 1376MHz.

Time to beat this card up a bit! devil.gif

Would've gone Extreme, but they only received 2 and they sold before I got there. They got 4 non Extremes, and I got the last one.

Didn't realize that Gigabyte had gimped the power limit on the non Extreme, though. But that's not an issue anymore.biggrin.gif

Gotcha, enjoy the new card thumb.gif

ctrl+L on the exact curve point of 1.05v, all to to the right of that is flat, yeah.

Here's my pic after 3 hours straight of Battlefield One, NEVER did it leave 2050, and I mean never.

Posted in the 2017 TITAN Xp thread, but I made a revelation that I think is significant and can help you all with the Ti, *or any pascal card really*

Figured it out!

You wanna adjust your curve points in increments or multiples of 13mhz at a time. You'll see offset values of 13,26,39,52,65,78,91,104,117,130...etc

When testing a point on your curve, lock it in by pressing CTRL + L in the afterburner voltage/frequency curve editor open GPU-Z and go to the sensors tab, run Heaven in benchmark mode or simply on a loop and see what perf caps you're hitting. You want it to just say Utilization, meaning there's nothing limiting your GPU Utilization, no bad clocks or insufficient voltages.

EXAMPLE



I'm still setting up my curve, but I will post back my values for each step once I'm locked in and fully stable with no perf caps. thumb.gif

Hope this helps you all and is clear.

1. A voltage curve can help you with stability. People have gotten past 2000 Mhz to get to 2088Mhz or even more.
2. Flashing the ASUS Bios gives you an additional 30 Watts. This has helped eliminate 75%+ of the power limiting you would experience in 1 hour game session.

And yeah, one day we might find a bios that gives us 50 Watts or 75 Watts. That will be number 3.

If I did the shunt mod, I could be playing at 2114-2128 Mhz. That would be 15% extra performance over stock clocks at 1850 Mhz. But I don't want to do the shunt mod, and hopefully a bios is discovered.

So yeah, **** please tongue.gif

Yeah shunt mod on the original bios is likely the best way to guarantee you aren't power limited, but I was curious if some of the aftermarket cooled reference cards like a couple of the EVGA's might get a FE bios with higher limits. Although I think its unlikely.

For your previous bios comparisons on Witcher 3, what was the max power on each, assuming they are pulling similar power they should give a good indication of how much the asus or msi bioses actually give the FE

I don't know honestly... I don't think flashing Bios do anything at all. Scores are always worse on the ASUS bios for me.

I think the key for the FE and even the Titan XP is to run at the lowest possible voltage at the highest clocks.

2088 Mhz @ 1.043 below on stock bios



Asus bios 2114 Mhz @ 1.083V

I think the Asus bios is working, but not perfectly. Kinda of like the Aorus bios has real problems, the Asus has minimal problems but I really don't think its giving 330w, more like 305. If it was 330w I think that extra 30w would get rid of all the power limitations in the Asus and MSI bioses in your Witcher tests as overclocking heaps doesn't increase power that much.

1911-2139 was only 12w
ram was about 3-4w


Looking at the Asus and MSI they both seem to have some lower voltage bins on the graphs, particularly when there is power limiting, and I would even goes as far as saying the MSI looks best as it only has little spikes even if its more often.

Something seems to be up with the ASUS firmware's memory settings. I've been seeing people with lower memory clocks compared to stock FE firmware. Maybe timings?

They probably are different, but I think there are other differences, maybe like the PCIE power and the 8 pin power are the same power limitations, and only the 8 pin that replaces our 6 pin is increased and hence the total. The real issue maybe the way it allocates phase power may mean we don't get the full benefit of that 8pin power increase and it then limits on say the PCIE power limitation. I could be completely wrong, but until I see an Asus bios pulling more than 111% I think its a bit suspicious.

Also unlike the days with bios switches on graphics cards, the OC mode is set in GPU tweak I believe, so maybe that switches in something else we can't. Interestingly GURU3D's card came with a bios locked to OC mode which has a different number, I think that one would be interesting to try smile.gif



Asus bios floating around is 86.02.39.00.23 that one is 26

Is it possible they're using a different shunt to measure power draw on the partner cards, in conjunction with whatever changes are being made at the BIOS level? I'm not sure if wizard has been addressing those parts in his breakdowns of the PCBs.

i.e. the FE PCB:

https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_Ti/images/front.jpg

The shunts are clearly labeled 5MO.

Gigabyte Extreme gaming:

https://www.techpowerup.com/reviews/Gigabyte/GTX_1080_Ti_Xtreme_Gaming/images/front.jpg

Not clear, but physically different.

Asus Strix:

https://www.techpowerup.com/reviews/ASUS/GTX_1080_Ti_Strix_OC/images/front.jpg

Not clear, but physically different.

MSI Gaming X:

https://www.techpowerup.com/reviews/MSI/GTX_1080_Ti_Gaming_X/images/front.jpg

Not clear, but physically different.
