Thank you for getting back to me. I've dumped my bios as an attachment here.

 

ROG STRIX-GTX1070-O8G-GAMING

Bios Version: 86.04.26.00.62

 

I appreciate your help!

 

Try the attached version. It has not been tested however since I don't have a card so flash at your own risk.

 

edit: BIOS removed.

I tried the attached version and I did not notice any changes in temperature, voltage or power limit. Everything looked and functioned identical to my stock firmware.

 

Is the file modified by your or are you getting it from someone else? I'm just curious where it comes from. Thanks again.

On second try, it looks like the bios actually did not flash and NVflash spit out an error. I missed it the first time.

 

Error pic is attached...

Yes don't flash this BIOS. I managed to locate a card and will get back to you when I have a working one.

I have a GTX 1070 Strix OC and i can hit 2050 MHz fully stable with voltage and powerlimits to the max.Above this point i need MOAR power.Very interested in a custom bios with unlocked voltage and higher power target(mainly this).Hope we see one soon

Hello, guys.

I used this bios (v5) on my 1080 FE for more than month and it work perfectly. The only thing I'm not happy with is fact that card is constantly work with 1.13v voltage at load bringing about +10C increase in temps (I have 41-42C with "normal" bios and 2100/1.06v and 52-53C with this mod bios with 2100/1.13v) But powerlimit seems to be lifted w/o any hardware modification. I can handle FSU with 2100 w/o frequency drops and get a 99+% in stability test. On any other bios frequencies are unstable in first test and result often less than 97-98% and due to constant freq and voltage changes during first test picture looks jerk. Also the results in FSU/TimeSpy are good compared to overclock on stock bios, that mean that card really works at 2100MHz and holds it.

 

Unfortunately this bios don't allow any great overclock over stock FE bios and stability. I can't reach anything more that 2100MHz for 24/7 use and playing some games (tomb raider 2013 for example) moved me down to 2050.

So I decided to set comfortable frequency about 2000-2050 at lowest possible voltage. Doing some tests shows that I need only about 1v to be stable at 2000-2050. But ... yeah, powerlimits come even at this values. Especially in FSU - frequency in first test fluctuates due to PL. I tried bioses with high power limits like MSI/EVGA FTW, but seems they do nothing for FE cards.

 

So my main question - is it possible to use this ASUS mod bios but limit it to 1v voltage? Is it possible to make this via MSI AB curve?

Or maybe somebody can release version with lowered max voltage, that lifts powerlimits but allows reasonable GPU overclock at 2000-2050 with low voltages instead of 1.13v+ ?

I find the solution to keep this bios and solved my problems.

Using curve in MSI AB I made it to work at constant desired voltage with constant overclock under load.

Default curve designed to use ~1.13v and with +150MHz in MSI AB offset gives ~2050-2100 overclock range.

While I want to use 1v max and stable 2000, I made a line with 2000MHz from 1v to 1.20v and now I have 1v max with 2000MHz

And this 2000 is rock stable and never drops, due to disabled power limits check. On any other bios running 3DMark FSU 1st test or Kombustor drops frequencies due to "hardware" PL on FE cards to about 1900MHz even on 1v on GPU.

So now I happy :) I got desired level of overclock w/o extra heat and stupid PL drops on other bioses. 1.13v with 2050-2100 made about 50-53C on GPU and now with 2000 1v I have only 40-43C on GPU under full load in real applications/games (45-46C in FSU loop / Kombustor)

 

MANTAcore

This bios allows up to 1.20v even on FE cards, you just need to make a line with some angle up to this voltage.

 

Here is how my curve looks:

This is my FSU with current bios/settings/curve overclock:

and here is a result that were made with offset overclock (2100 1.13v):

and here is Time Spy:

2000 1v

2100 1.13v

Hi guys, I just migrated over from xs, what is the best bios to use on my 1080 sc (with water cooling)?

 

I would prefer not to use a fixed voltage bios but will use one for benching and see how temps go.

 

(sli issue sorted but thermal throttling badly)

 

Thanks

Hi Fellas,

 

Here’s the original BIOS, NVFLASH and the XOC BIOS:

1080strixXOC.rar beim Filehorst - filehorst.de

Just drag and drop the XOC file on the prepared NVFLASH shortcut…

 

This BIOS has no powertarget and a fixed measured voltage around 1,24V. If you try this BIOS on air, you’ll notice a very fast increase temp-wise, so be careful.

I did some initial testings with the original BIOS and found that 1,24V is good enough for 2250 to 2300.

 

Hi guys,

 

I have been trying desperately to download this file from the website in the link but there are adverts and I don't speak german.. I have even tried translating the entire web page and clicking on different things but it comes up with more adverts to porn sites etc...

 

Can anyone talk me through what I need to click in the order or send me the file please? Would be absolutely amazing if someone could help.. thanks so much.

 

email address: nick.peyton@btinternet.com

 

Thanks a million from Scotland :-)

Use the later t4 bios from here http://forum.hwbot.org/showthread.php?p=455871#post455871

I successfully flashed this T4 STRIX BIOS to my EVGA 1080 Classified.

 

It works okay in one aspect -- seen it go over 1.093v for a brief moment....

 

However not so good in another. No matter what I do I can't get my Classified to draw more than 110w power.

...I think because the power limit has been completely "removed" instead of just "raised" my card is defaulting to a 'fail-safe' low power mode. Either that or the differences in the power management system are too different between STRIX and Classified 1080's.

 

The STRIX BIOS did allow me to go over 1.093v for a moment and 100% fan on this BIOS also yielded an extra 1000rpm.

 

I have tried many other BIOS's, the power draw problem seems to be isolated to this one.

 

The original power limit of the 1080 Classified is 320w when the bios switch is to LN2 mode.

 

If I could find a BIOS with a high power limit -- but 'with' a power limit -- with the same voltage adjustments as the T4, this would be fantastic. I have spent all week desperately searching for this elusive BIOS lol...

 

If anyone could point me in the right direction this would be absolutely fantastic!

 

Or in direction of where I might find a Pascal BIOS tweaker.

 

At the moment I am limited to testing by locking voltage in MSI AB to 1.093v.

 

Have a nice day :-)
