Ragazzi , piccolo OT : C'è nel forum una guida per sbloccare il voltaggio delle kepler....
Io nella mia 690 come faccio dato che è una dual gpu? GPU-Z mi salva il bios solo della seconda, non arriva a salvare quello della prima :'(

Teoricamente il problema non è salvare il bios (quello di una dovrebbe andare senza problemi sull'altra), ma bensì di flashare entrambe...
Non so proprio se nvflash funziona anche con le dual.
 
non saprei :P
Prova a installare nvflash (o anche il programma che consigliano nel thread) e vedere se è possibile flashare entrambi i bios :)
Ma poi siamo sicuri che anche le dual gpu non abbiano comunque solo un bios?

Ho trovato questa guida in inglese , ma a me non salva il bios della prima gpu D:

I wrote this guide as i couldnt find one anywhere.

First of all, You then need to download these files.

GPU-Z (This is used to grab the original Bios from the Gpu wether multi or single)
Download TechPowerUp GPU-Z v0.6.6 | techPowerUp


KGB - Kepler BIOS Editor/Unlocker. (This is used to modify the Bios that you just grabbed from your Gpu using Gpu-z)

KGB supports: GTX690, GTX680, GTX670, GTX660Ti, GTX660OEM and GTX660

NVFLASH (This is used to reflash or reinstall the new modified bios)
http://www.softpedia.com/progDownloa...oad-16133.html

Steps 1-10.

1.Ok what you need is firstly to make a USB dongle bootable into DOS, To do this read this very easy to follow guide.
How to format a USB memory key

2.Run GPU-Z and and click on the icon that allows you to grab your bios from the Gpu and save it to your PC.

The pictures below show how.....

Also make sure you have a copy of your bios!!

3.Once you have grabbed your bios put it into C:\Users\My and rename it 1.rom

For example the bios from the GTX 690 Gpu 1 is called GK104.rom, I renamed it to 1.rom and the bios from Gpu 2 I renamed 2.rom.

The reason why you should put the bios in C:\Users\My is because the default path will be set here from KGB.exe so if you are not familiar with the CMD (Commandline) then this is the easiest way of doing it.



5.Take the KGB.exe as well as the KGB.cfg file and also place both of these in C:\Users\My.
You should now have KGB.exe, KGB.cfg and 1.rom files in C:\Users\My.

If you have more than 1xGpu then you will have 1.rom and 2.rom respectively in C:\Users\My.


6.The next thing to do is open up the CMD (Commandline) which im sure you all know how to do.
Once you have the CMD open, Copy and paste in this command.

kgb 1.rom unlock (press enter).

It will now save the new values (i.e. from kgb.cfg) in your bios then print out the new values in the bios.

7.Now all we need to do is put the new modified 1.rom back onto the gpu, To do this we need to use the USB DOS bootable Dongle that we created in step 1.

Take the nvflash files once you have extracted them and place them onto the USB DOS bootable Dongle, There should be 2 files.

Then place the 1.rom bios also on the USB DOS bootable Dongle.


8.Now the Dongle is ready to be booted from so reboot the PC and go into the bios.
Once you are in the bios make it so the PC boots from the dongle, Once this happens you will then have a flashing cursor telling you that you are in DOS mode.


9.Type in nvflash --list (press enter)
This will then tell you what gpu(s) that you have installed on your motherboard.

10.Type in nvflash -i1 1.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.

If you have a second gpu with 2.rom.

Type in nvflash -i2 2.rom (press enter)

It will then say flashing Gpu and press Y to confirm, so press Y and the flashing will commence which takes a few seconds.



Once this is done reboot the PC go into the bios and reset your boot so it boots from your hardrive with the Windows OS on.

Once you get into windows you can see from MSI afterburner or EVGA precision that the power target can be raised from 130 to 150.

When gaming the boost clock should be higher depending on your GPU.

I achieved around an increase of 30 on the core clock on boost alone on both GPU's which is very good.

It will differ for each person and each GPU(s), You can also try other peoples bios as long as iyts the same GPU as your own.

You can also modify the KGB.exe and tweak power settings for even more results but I wouldnt advise this unless you know what you are doing, I would just leave it at stock and use that for the time being


 
Secondo me la VGA presenta un solo BIOS....quindi quando lo vai ad esportare per poi modificarlo utilizzi solo quello...non credo proprio che possa utilizzare due BIOS anche se è pur sempre una dual chip...
 
Grazie però a me fa vedere le due gpu , una con bios 80.04.1E.00.13(p2000-00g1) , e l'altra con 80.04.1E.00.14(p2000-00g2) CHE PRESUMO sia della seconda.

Se salvo il bios della seconda me lo fa salvare , se salvo quello della prima mi scrive : BIOS reading not supported on this device.
Tutto ciò su GPU-Z

Ragazzi ho provato 6 versioni di gpu-z e alla fine la versione 0.6.9 mi salva il bios di ambo le gpu :lol:
