makatech Not 100% sure yet but I believe I am able to clock my memory slightly higher after flashing my vanilla Aorus 1080Ti non Extreme card with the Extreme bios. Don't think I managed stable settings +600MHz in Afterburner earlier but now I do. It doesn't have to be because of the Extreme bios, maybe the old bios (86.02.39.00.9D) I was running was slightly outdated.

Thanks, testing some different voltage curves in Afterburner using the Extreme bios on my non Extreme vanilla 1080Ti card. I highly doubt there is a big difference, the biggest difference is probably slightly higher stock/default clocks on the Extreme bios (which is nice if not overclocking using Afterburner). If overclocking using Afterburner I doubt the Extreme bios giving higher performance comparing to to non Extreme bios on a non Extreme card.

Not sure yet if I will go for maximum performance or if I will try to optimizing a 1000 mV curve in Afterburner giving me slightly lower temps and perhaps a more stable fps. Did some quick tests yesterday and a 1000 mV curve giving me between 10200 - 10300 in Time Spy comparing to when going for maximum performance I reached between 10700-10800.

Yes, unfortunately I have air cooling too. Talking about GPUs then cooling with water helps a lot, that's for sure. Many users are using AIO for CPU but not for GPU, probably a mistake since water cooling the GPU would give many users a bigger total performance boost (at least for gaming) comparing to water cooling the CPU. Perhaps I will try cooling GPU with water in the future. Very nice being able to run the system more quiet and with higher performance.

What about wb version bios 86.02.39.00.DC on a non Extreme vanilla Aorus 1080Ti, very bad idea/impossible ? ;-)

Did you try the FTW3 Kingpin bios?

I am trying this now, running the Extreme bios on my Aorus GeForce GTX 1080 Ti. Currently have everything else on default right now (no Afterburner tweaking at all yet).

Actually first time today updating GPU bios, I have never been playing with GPU bios before.

Used the guide here:
https://www.overclock.net/forum/69-n...r-1080-ti.html

using nvflash64, first using the protectoff switch, then saving a backup and finally flashing the bios.

Reinstalled Nvidia drivers using DDU.

Only issue so far is Chrome was black when launching it which was fixable (finding an easy solution on youtube).

Tried some kind of benchmark for 1440p in MSI Kombustor. When running the old bios I scored 2404 points, running the new bios I scored 2464
https://gpuscore.top/msi/kombustor/show.php?id=349073

Now bios 86.02.39.40.5E
earlier 86.02.39.00.9D

Do you know if there are any major differences between Extreme and non Extreme bios for this card? The only thing I notice myself is base clocks for GPU Clock/Default Clock, Memory and Boost being slightly higher (small difference). Perhaps the only advantage running Extreme bios on the non Extreme is it will give you slightly higher speeds in default mode (very small difference)?

ylpkm Looking at the 1080ti fe memory trimpot mod the board layout is a bit different. Was wondering, anyone know where the gddr5x trimpot mod location is on this card?

lowmotion Got 2x 1080Ti Aorus, one normal and one xtreme. Both are very close in terms of clock. There is no good way too boost the performace much higher. OC Scanner gave me about +30-50mhz (not really stable) and +400-500 on memory. Never used the shuntmod.

One of my 2070 was fun: needed 3 days to find a secret Bios to unlock the PL a little bit and about one week to find a waterblock outside of the public lists. In the end its all you can do: flash better bios, change to watercooling and use better thermal pads. OC Scanner gave me about +200 on clock and +1300mhz on memory. Its different from the 1080Ti. Much more potential.

Protipp number 1: the PT contains the leds on the card. Disable the leds and you get a few watts for the powerlimit.



Nice to know:

How sensitive is this card to heat?? during extended gaming sessions the core clock sits between 1976mhz and 2000mhz, and doesnt go much above 79c or so. I am considering replacing the TIM with MX4. worth doing?
2000MHz is default on this version.
The relation between temperature and clocks is not so simple. You lose 12MHz every 10c or so, but higher heat also induces more power limits which also cause the card to downclock.
Changing Thermal paste won't make your overclock better, but it might make your card more quiet (Temps would probably drop by 5c-10c if done right, since that paste is 3+ years old). The problem is, if you want to work right, you would probably want new thermal pads too. This card is also kinda a pain to disassemble with all the RGB connectors.
I think on air you could maybe do something like 2038/5800 stable. With water something like 2076-2100/6000-6200.

With Aorus 1080ti it's even more annoying, because it has dual bios. So if you flash something on DP, and then let's say connect do a DVI monitor, the drivers re-configure themselves. This by itself can cause more issues than any benefit a bios flash might have (of course, DDU solves everything, but why bother?)

So to sum it up, I really don't recommend playing around with bioses.
BUT...
If you're in the "I got a beast card and I want to push it to its absolute limits, no % left behind" phase, which I've been in, then I suggest you flash the FTW3 Kingpin BIOS from the 1080ti bios thread. The reason is that it's a bios that deals better with power limits, you can put voltage at 1.093V and not worry about downclocking. I've tested it myself, and it works. I had 2088/6100 fully stable, no artifacts no crashes no power limits on the most harsh tests in the world, that consumed over 350W of power for extended durations, 4k and 8k resolutions, full VRAM load, etc.

That said, with stock bios I have 2076/6000 on lower voltage, so it doesn't power limit much, and 2050/6000 doesn't power limit at all. So all this bios work, one DP output disabled, etc... for just 38MHz... not worth.
Thanks for the info. I got the wb version bios 86.02.39.00.DC. I have it run stable at 2066 stock voltage. I was thinking to flash ftwkingpinfix to see how far i can push. But then i read yours and it seems like it's not worth the try for a few mhz and losing some ports.
