You're in the wrong forum to be judgmental. And I'm sorry, but it takes baby steps and a community together to push boundaries biggrin.gif. If everyone was lazy and condescending as you were, then nothing would be discovered:thumb:.

As for myself, I set out to prove that flashing the ASUS was a waste of everyone's time because I was concerned others would waste their time.
Hell, he's johnny law, so.... impossible for him not to be judgemental and overbearing and out of line. And lazy.

A lot of the water cooled / AIO BIOSes are like this and I don't know why. A water cooled card is the most likely to run into power limits since thermals aren't an issue, but the manufacturers keep making them on PCBs with weak VRMs and with low power limits.

On the MSI 1080 (non-Ti) Seahawk X they gave you a LOWER power limit than even the FE! At least with this one they kept it the same.

vs
https://www.techpowerup.com/vgabios/184559/msi-gtx1080-8192-160607

I guess they really don't have a lot of faith in their hybrid VRM cooling....

Can you point me to the addresses you found the power limits at?

"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -q -d power

Here's my dog of an Aorus. Having difficulty getting 2000MHz stable, really got a crap draw of the lottery. mad.gif

sorry to hear that man. I always draw short straw. I guess getting an Aorus that can hold 1650 core was a big win for me this time, i better at least realize it.

Can yours hold the 1607 base of the Extreme? Have you been trying to add voltage?

I don't think we are going to be able to sign it ourselves anytime soon.

The 'certificates bypassed version' of nvflash already exists, and its even been updated to be pascal compatible.

The problem is deciphering the BIOS files. (figuring out what to edit).

I could use a hex-editor to edit my BIOS file right now, and I have the tools to successfully flash it to my 1080.

The problem, is any edit I done.. would be a "shot in the dark".

So, I hate Microsoft mad.gif
AWESOME! I am so glad you got that worked out. Yours was such a sad tale. Now we need the dude with the lost Discover card to get his EVGA.

150% of what, though? 150% of 250w is 375w. 125% of 300w is 375w. I think they will perform the same and the only difference between Aorus BIOS after the final revision (like I have, 300w target, 125%=375W) and the 150% one is the target limit and the base clocks. It should perform the same when OCing, w/ lottery being the only real variable.

Honestly, the card looks like a reference.
it's close. Only difference is the look, the power phase consistency, the cooling, and the power limit won't be a problem with 375w to play with. But I'd say all of the above favors Aorus tongue.gif

Sure thing! For future reference - all the Pascal cards have mostly the same relative offsets between bits of data in the BIOS, although the starting offsets are different from GPU to GPU (1070, 1080, and 1080Ti offsets are all different)

The below data is from the 1080Ti FE BIOS - the offsets should be the same between all 1080Ti BIOSes, so if you want to know the max TDP adjustment limit for any 1080Ti BIOS, just open up your hex editor of choice, jump to 0x00030e78 and read those 4 bytes. Don't forget to swap from little endian to big endian before converting to decimal.
Code:
1080Ti BIOS offsets:
Note - in the BIOS the numbers are stored LSB first, so if you see "48 e8 01 00" in your hex editor, you need to swap to MSB first notation before converting to decimal.

"48 e8 01 00" would become "00 01 e8 48" which when converted to decimal = 125000 which is your Min TDP target in Milliwatts.

Min TDP target                  DWORD - 0x00030e70 - (48 e8 01 00) = 125000mW = 125W

ooooh baby cant thank you enough, made my life so much easier and saved me so much time.
First thing ill try now is to manually edit the BIOS and flash it on using a programmer.

Will let you guys know how it goes tonight or tomorrow night.

Haven't figured out why I can't run it and have afterburner open at the same time. Might have to email 3dmark support.
it's your NVIDIA control panel settings, (ive been meaning to tell you this- i got you, mane!!) . One is shader cache, one is Anio filtering, ... there are more. Just set EVERYTHING to default or "application controlled". For me I kept getting hung on Timespy and getting a launch error b/c I usually run 16x Anio filter from NCP overiding, and Timespy hates that.

Does that extra power from the shunt mod really matter? What are we talking here, 25mhz on top from 150% power draw?

That PSU that can measure power draw sounds sweet, sort of want one.
