7970 DCII voltage locked, how to unlock it?

psyside · Jun 24, 2012

Anyone got idea how can it be done? does vBIOS help? please answer me, all of the recent 7970 DCII/TOP cares are being voltage locked

radrok · Jun 24, 2012

Have you tried with turboevo? The Asus proprietary software.

psyside · Jun 24, 2012

I will be honest, i still don't have the card, i want to buy it, but i'm really scared if its impossible to unlock, because many users tried, different vBIOS, different software (trix,gpu tweak, afterburner etc) and nothing seems to work

BTW turboevo, its for Mobos as far as i know? :/

radrok · Jun 24, 2012

yes, sorry it's called GPU Tweak, I used turboevo naming because that's what I use for my ASUS motherboards.

I've never bought an Asus GPU though only MSI/Sapphire.

That's good enough for me not to buy that card. Look for something else. Yeah those coolers look cool, but they don't work as well as they should.

crazyeyesreaper · Jun 24, 2012

meh mine works fine voltage unlocked tops out at 55c at 60% fan speed (silent until 70% is reached) at 1125 core, sucks if they are actually limiting the cards potential these days.

Thanks, when did you buy the card?

Just now I managed to unlock the voltages. The only bad thing is that the voltages are stuck in 3d mode.
Anywho, here's how I did it:

- Download and unpack the ATIWinflash onto your desktop in a folder called "winflash"
- Save this BIOS in your Winflash folder and name it asus.rom
- Click Start Button
- Type "cmd"
- Right click the entry and select "Run as Administrator"
- Black command prompt windows opens
- Type "cd %USERPROFILE%\desktop\winflash"
- Type "atiwinflash -unlockrom 0" <-- the 0 means first adapter, if you have multiple cards, physically uninstall all but the one you want to flash
- Type "atiwinflash -f -p 0 asus.rom"
- It should complete the flashing process with a message saying something with "verified".

This is a copypasta from w1z with some modifications.

EDIT: I'm not sure why, but, my Heaven score has increased...
EDIT2: I changed the 2d clock to the lowest it will go, 465/2760 @943mV. It used to idle at 33C, now it idles at 40C.

Thanks alot for this! can you please tell me did unlocking get your oc better/higher? is this metod safe? can i brik the card? thanks again!

So far I haven't noticed a difference in the max OC. When I slap on the waterblock next week I'll check again. The card has 2 BIOSes.

EDIT: However, you should note that what's stable at 1080p/1200p is a crash-fest at 1600p.

psyside · Jun 26, 2012

Thats disappointing, and led me to think that this card where locked with reason, looks like this card have VRM/Power delivery issues, because your the second user who unlock his card, and got 0 increase regarding overclocking even with voltage control unlocked, so disappointing

Doesnt work.

yes it unlocks the option in Asus GPu Tweak but it doesnt actually give you any type of control over the voltage

GPU tweak shows 1.084v No matter what voltage i put on that slider, it never raises
Max overclock is the same

MSI Afterburner still cant change the voltages.

vadimua · Jun 28, 2012

It works on my DC2T.
This BIOS is not stable, but you can overclock fine.
Attention.

GPU tweak shows 1.084v No matter what voltage i put on that slider, it never raises

After flashing the BIOS, do not touch the switch on the card.
And do not change the BIOS settings MB.

If this happens, and the voltage stays 1.08
1. Flash your old BIOS from DOS.
2. Login to Windows, and reboot.
3. Flash the OC ASUS bios fom DOS.
4. Login to Windows and open Tveak GPU. And use.
So it works for me.
Sorry bad english.

Iactus · Jun 28, 2012

can i see the Monitor that shows your voltage at a higher level?

I havent touched the Bios Switch, I flashed it from in windows, there is no need to use DOS when the ATIWinFlash is so stable.

Mine is a DIrectCUII Not the Top version so i may have a deeper hardware limitation to the volts

vadimua · Jun 29, 2012

Iactus

Standart BIOS

OC BIOS

Iactus · Jun 29, 2012

You lucky Bugger

Mine is locked still

Also Your GPU tweak looks So much better than mine, i have the same version aswell

Seems the DC2 TOP Is a better card than the Non TOP version

Fimconte · Jul 12, 2012

Took a leap of faith and flashed the test bios to my DCII non-top (HD7970-DC2-3GD5)
'lo and behold, voltages unlocked in GPU Tweak!

The only problem so far is that DVI Port 2 (the DL/SL variable one) doesn't work.

Which is a minor annoyance for now (I used a DVI monitor in the DL slot and a DVI->HDMI adapter for a HDTV in slot 1), but since I ordered 2 DP->HDMI adapters that problem should be solved soon (unless the bios flash did something to the DP ports as well...).

Which ports did you use @vadimua, @razaron?

Going to do some benchmarks to see if I can break 1200mhz now (had artefacts in Furmark with 1.175mV @1170mhz+)

razaron · Jul 13, 2012

I'm using DP through an active adapter.

Let us know how much you can gain by using that bios and the full 1.4v man :toast:

Please link us to the download for this bios and what u did exactly.

Also which drivers are you using?

Fimconte · Jul 14, 2012

radrok said:

Seems like no gain...

Although for some reason I have a lot of vdroop from 1189 to 1.117mV, Coincidence?
I mean I can push 1200mhz, starts off fine, but once the vdrop kicks in, so do the artifacts.

Alternatively, maybe my PSU is dying... It is starting to get quite old now, and perhaps it can't feed 7970 enough power...

Either way it's disappointing that I have to flash some test bios to unlock voltages, when reference card has these unlocked by default and can hit quite high core clocks.
Going to see if I can return the card next week I think...

Same bios as posted in the above guide.

12.7 Drivers.

Mabey these batch of chip's cant handle the higher volts and is why there locking them down :confused:

Iactus · Jul 14, 2012

gThey fly when hardmodded.

I suspect that guys unlock did nothing but mafe it seem it uped the volts.

If it did he would hit 1.25gz easy.

So it seems they are still locked.

I will be hardware modding mine
