No, I even tried to put back my 980ti, install without problems 381.65 drivers and change videocards to 1080ti, 980ti works like a watches.

Guys, for AIBs- do you still use that AB custom voltage curves thing or do you use some new AB version where we can finally just apply voltage with slider?

Rather than digging through the code and hex values like I've been doing, if you actually have the card in hand:

Load up a command prompt (cmd) and copy/paste the following:
Code:
"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -q -d power

You'll see a nice little text output like this (it's from my 1070 as i'm still waiting on my 1080Ti to arrive)
Code:
Timestamp                           : Mon Apr 10 15:15:39 2017
Driver Version                      : 381.65

Attached GPUs                       : 1
GPU 0000:02:00.0
    Power Readings
        Power Management            : Supported
        Power Draw                  : 35.86 W
        Power Limit                 : 199.32 W
        Default Power Limit         : 166.10 W
        Enforced Power Limit        : 199.32 W
        Min Power Limit             : 75.00 W
        Max Power Limit             : 200.00 W
    Power Samples
        Duration                    : 2.69 sec
        Number of Samples           : 119
        Max                         : 36.45 W
        Min                         : 8.99 W
        Avg                         : 32.49 W

This also gives you an easy way to see absolute TDP numbers rather than percentages like GPU-Z gives you, which is nice.

From this, you can also see that the sliders in most GPU tweaking software seem to round to the nearest integer percentage. For example my slider only goes to 20%, which gives me 166.1w * 1.2 = 199.32w, even though the card technically supports 200w. If you really want that last .68w of TDP headroom, you can actually use nvidia-smi to set the power limit via the command prompt.

This is also handy if you want to add the command to a batch file and increase your TDP limit without having to have any OC software start up in the background, as they eat up memory and (rarely) have negative interactions with certain games.

To set a new power target, make sure you run the command prompt or batch file with admin rights, and type:
Code:
"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -pl <newpowerlimit>

The output should look something like this, which for me gave me the extra .68w of TDP that my 1070 Strix OC BIOS was capable of that Afterburner and the ASUS Gpu-Tweak utilities weren't giving me smile.gif
Code:
C:\WINDOWS\system32>"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -pl 200
Power limit for GPU 0000:02:00.0 was set to 200.00 W from 199.32 W.
All done.

That's interesting, but how does this data work with a bios flashed from another card.
post #4704 of 10663
So basically flashing another BIOS isn't going to help me much without a shunt mod? I game at 2050-2062 with an offset on a stock cooling FE card that is about to be modded with an AIO.

It works exactly the way you'd think. It shows all the relevant data from whatever BIOS you currently have flashed to the card.
I have a Strix 1070 non-OC which technically came with an FE power limit of 150w/171w, but I currently have the BIOS from the 1070 OC version of the card flashed to it, which gives me the higher 166w default TDP limit and 200w max adjustment limit.

nice work. so as you can see, regular aORUS IS 300W LIMIT WITH 375W ENFORCED AT THE 125% SLIDER. nO NEED FOR THAT 150% SLIDER AT ALL ON THE EXTREME.

only time i've encountered it was on an old msi r9 280x that wouldnt take drivers and it had to go for an RMA, I'm very sorry to say, and I hope I am wrong.

Both. But Aorus doesnt want any extra volts and the consensus is that most cards work better locked to 1.04v/1.05v/1.63v anyway , at highest possible clocks. So, determine highest possible clock at 1.050v, at crash lower it 13-25, drop everything down to the right of the straight across same line mark . click 1.05v and hit ctrl+L to lock, x out, apply, save, and enjoy. It's really easy now.

Yeah a big issue is people thinking that flashing the Asus bios is giving us extra power when no one has actually measured it yet.

The Asus strix bios has a power draw of 275 and 330 max. Well when we flash it on the FE, we can only get up to 110% power draw on this bios... Guess 275X1.1= 300 watts, the maximum power draw of an FE card.

We're not getting any benefit with this bios and other users keep swearing on their mom's souls that they are getting improved performance when they haven't even done any real test to compare to one another.

This issue isn't you're only getting 110% power draw it it's only hitting 110-111% of the Power Limit, which is good. Most FE BIOS's start hitting the wall at 112-113%, it's well documented in the 1080 Ti forum.

Which version of the Aorus Extreme BIOS are you running? There are actually four in the wild apparently (F1, F2, F3, F4) with reports that some of them actually have different power targets. Some people were unhappy when they found out that their Aorus Extreme only had the TDP slider going up to +25%, but your results make sense now if the base had been raised from 250-300w.

Interestingly, the BIOS shipped to reviewers is definitely 250W by default with a +50% adjustment limit, as shown in TechPowerUp's review - it's the same one they posted in their BIOS database as well - from the text string it looks to be F3.
