VBE7 - vBIOS Editor for Radeon HD 7000 series cards

[Marsellos]

Now I flashed the normal vBIOS modified by myself and everything is fine with VVDC voltage
BOOST vBIOS is really unstable and clocks go up and down everytime, and some games dont start with normal clock and stay at "State 3" with 300-150...
I really don`t understand that but anyway now I have all the settings that I need.

Hello sentye.
Yes I can't change voltage my vbios with vbe7, raise or lower. Also I would like it to modify that I could change voltage in vbe7.
If you can modify, make this please!
Thanks

Hey

I can modify some settings, but if you are talking about a possibility to choose a voltage from a drop down list like in the image below, then this isn't possible for your vBIOS.
This is how VBE7 is designed, a drop-down list with predefined voltages is only available for unsupported VRMs.

However you can still set new voltage in your vBIOS by writing new 3D voltage next to VDDC, of course
it isn't guaranteed that new higher voltage will work correctly.

With that said, if you want any modification to be done to your vBIOS then please post details what should be changed i.e. new clocks, voltage or whatever you want.

Regards

Hi all!

1st, sorry for my english! So, i have an Asus 7870 DirectCU II (HD7870-DC2-2GD5-V2) and when i use only one display (on DVI, on hdmi not matters) , i get green dots on the screen in 2D. If i increase the 2D voltage only by 10 from 825 to 835, everything will be fine. I made a profile in asus gpu tweak, but i'd like to change the default 2D gpu voltage in BIOS. Can somebody help me. how could i change this?

I saw this:

• You cant set 2D / UVD clocks higher than the values stored in BIOS (these limitations are intentional, without these limits powerplay would go nuts...)

, but is not it possible to change this voltage to work my card fine? Or, i still have warranty on the card, change it back?

Thank u!

Hi apacukaa

Yes it's possible to change that voltage, but for that you'll need to use a Hex Editor such as HxD.
If you want I can make that for you, just upload your original BIOS and I'll modify it.

Ohh, thank you!
Here is the default BIOS:

http://www24.zippyshare.com/v/96416266/file.html

So, 835 is enough, maybe it drops too much, or i dont know!

Already done

Check with GPU-Z or any other tool if new voltage is reported properly after flashing this vBIOS.
If it still shows default voltage, then let me know and I'll see what may cause that.

Hello sentye,
Please ,I would like clock 1125 and 3d voltage 1200mv.
Thanks

Hi,

Anyone got more explanation on PowerTune TDP? I have an Asus HD7970 DCU2, right now, Powertune is 217, 174 to 260 ( I always use Max 20% in the driver), and my VDDC is set to 1225, for 1150/1600 (I think my card can go up to 1700). 1170mv and 1225, I still can't get over 1150, could it be the TDP? this card is quite cool, so I could go up to 1260 maybe more..

Want to get this 1200 xD. But any explanation on PowerTune TDP, and where we can get max would be nice

Thanks

Hey Guys.

I got a XFX 7870 DD and was using a modded Bios because the Voltages as Stock were just overkill. The Problem is that when using 2D/UVD Stock VDDC is 0.95 which is figgn much. The modded one used 0.8 which did run ok but not fine.

I thought it would be possible to change them with this tool but then realised its not possible.

Is it possible that someone changes the entrys for me per hex to 0.85 for 2D/UVD ?

Thank you in advance

Can someone still check it ? seems to be overlooked

The Bios i posted is the original one.

Hi

I've set new 3D voltage in your vBIOS to 1.200V as you wanted.

Please test it and report back.

Hello!

I flashed it and works perfectly! Thank you!!!!!

Hi sentye
It is impossible to open the file, it is damaged.

Hi sentye

You must use WinRAR 5.10

Yes, you are right, works. Thanks.
Then I will try flash Bios and I will let know.

Hi KennyW

I've changed voltage for 2D/UVD in your vBIOS to 0.850V.

Check if everything is working properly, especially whether this voltage is enough for UVD state, as I've some doubts about this.

Before flashing new BIOS first make a copy of your original BIOS.

Hello sentye,
the vrm is unknown voltage regulators, max voltage is 1200mv.
Please ,I would like max 3d voltage 1350mv.
Thanks

Hey ,

Thank you very much. It runs well but the VDDC under GPU-Z still says 0.950V which i guess is just a display error because when i use VBE to check the Bios it tells me the VDDC is 0.850.

What does worry me a little bit is that the temps are bout 10C hotter than usally while in idle :/ (In comprasion to the Stock Bios)

I am going to post the Bios which i used earlier , which had just 0.8 but Video Bugs while in 2D ( This one also Displays 0.80 on GPU-Z)

Hey, thanks for reporting as it wasn't a display error in GPU-Z, but I actually forgot to change default voltage at one of the Offsets so your GPU in fact is still using 0.950V for 2D/UVD.

Anyway I've changed everything what was needed, so now all should be fine.

Hi fffccceee

I've set new max voltage to 1.350V, but also preserved default voltage of your vBIOS.

Just remember that simply overvolting your GPU through BIOS may or may not work, even if GPU-Z reports new voltage properly the actual voltage might be different - lower or same as default. So to get correct readings of actual voltage used by your GPU you'll need to use multimeter.

First make a backup of your original BIOS, before flashing new one.

Regards

EDIT:

I re-uploaded new edited version of this vBIOS as in previous I made mistake in voltage table.

Hi ISD

Give more information about your problem i.e. if you want anything to be edited in your vBIOS then post details about what you want.

i want to increase voltage to 1.2 roughly. it's possible?

 

[sentye]

If I understand you correctly you want to set 1.200V as your voltage yes?

It's possible but that means I'll need to replace one of these voltages from the table so do you want to preserve 1.250V as max voltage or should I replace it with new voltage?

Of course I can replace any other voltage like 1.081V, but it's up to you.
