How to enable additional shaders on Radeon HD 6950

[Michelle911]

answered my own question, thanks anyways

 

[nazmy]

when whe modded 6950 to 6970 should we use 6970 drivers or continue to using 6950 drivers? and another question is before we flashing the graphic card should i uninstal the driver? then install drivers again?

Asus 6950 unlocked fine

Hey i followed this thread and tried out unlocking my Asus 6950 2gb.
I used atiwinflash and it all worked fine..only problem was i forgot to uninstall drivers first so when i started pc after flashing it was all black, but i had another original 6970 that i put in main slot and the flashed 1 in other slot..then started pc and all worked fine after reinstalling drivers.
Thanks for good info guys..love it ^^

6950 and 6970 use the exact same drivers, so you use the latest Radeon HD Series 6xxx drivers for both. (or what ever betas you want that support the 6xxx series)
And yes un-install the drivers and flash, reboot and re-install drivers.

Hi guys...

I'm new in this forum, sorry for everything I will do wrong...

In the last days I have tried to flash BIOS of my HD 6950, Sapphire Dirt 3 Edition...

I follow the guide, downloaded batch file but after flash the card doesn't boot!

I try to restore the original BIOS with batch, but the card continue to don't boot when I set and flash the BIOS on 1 position...

What's happened? Thanks to all...

Sorry also for my bad English!

EDIT: I installed original BIOS from prompt, but every Sapphire 6970 BIOS not boot after installation... Is my card unlockable?

I would say probably not.

It didn't work for my gygabite 6950 1GB

I tried wiring the switch and without, tried doing via atiflash in dos and winflash

In both methods it says that it was flashed, but shaders won't go higher than 1408.

Does this mean that its impossible on mine or I am missing something ?

Won't work

Well, there is a situation that still unclear to me. HIS6950 via 2Gb RAM flashes perfectly, but... It has no sign of life during OS loading (Win 8.1) but in system it works correct (unlocked shaders, clocks and etc). After switching to Win7 card does not boot at all via modded bios (the original one seems to be fully working). I tried to flash bios that has only unlocked shaders and it worked perfectly except locked max clock values. What am I doing wrong?

 

[Schmuckley]

That's probably a UEFI thing.
It gets tricky with newer boards/older cards.

 

[TheSatan1st]

I also have this supposition but don't have another MB to check it out. By the way, I'd found some kind of solution: I'd modified stock bios (saved from my card) by unlocking 6970 shaders count and raising max allowed clocks (modifying stock clocks makes my card not-recognizable)

Hi,

First, sorry for my english...

I got an Asus 6950. I unlock to 6970 yesterday (work after doing the dos commands)
My motherboard is a gigabyte ga-ex58-ud3r.
I am under windows 7, 64 bits.

Now, in GPU-Z, i got 1536 shaders and 890 Mhz : ok. (tested in game)

My problem is : if i overdrive gpu on AMD, when i launch a game, my screen "freeze", then windows says the amd component wad not answering.

Tested with farcry 4 : problem on the launch, fallout 4 and witcher 3 : ok on the menu but after loading of my save, same problem.

And of cource, when it was 6950 not unlocked on 6970, the OC of GPU work fine.


Thanks

3D isn't working, you'll need to flash it back(if you can)

just noticed this thread here , i scored a pair of msi 6950s about a month ago for $60 , both cards were unlocked no problem

For the people who need to unlockrom and fail at command line:

- Unpack the Winflash download onto your desktop in a folder called "winflash"
- Save the 6970 BIOS in your Winflash folder and name it unlock.bin
- 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 unlock.bin"
- It should complete the flashing process with a message saying something with "verified".

Looks like I have failed on this one.
I had one 6950 (Sapphire Dirt3 1Gb) which was unlocked successfully than I bought other one (same model).
That "other one", had write-protection (Could not erase ROM) so I tried this method. Flashing was failed, now it won't even boot - symptoms are like you "overdrive" with overclock. Fans are spinning, on every 3 seconds they speed up for a moment, like MoBo is trying to load default BIOS settings.

Now, I have 2 questions:

1) Problem might be that I flashed *.ROM file which I get from latest GPU-Z or ROM is same format like BIN?
2) Or the problem can be that I flashed ROM from first card to second one not checking does both cards have same DDR installed.

Also, I would appreciate if someone can suggest me how I could put back original BIOS on this second card. I have backup but as i wrote before, it is in ROM format.

Thanks in advance!

sorry for making you have to reply 7 years later but i bought one of these for $40 aussie dollars and wanted to flash it but in your post it says rename it unlock.bin what exactly do i rename because the bios file is a .rom file and im not sure what to rename! anyway your help will be greatly appreciated if you can and have a good new year

thanks

It's just the file extension, both of the files contain the same programming code.
You can safely rename the BIOS file to .bin and .rom or .rar, even. Whatever you want it to be, and it'll still flash successfully and safely.

Hello, hopefully someone can help me with my issue;
After flashing and unlocking my MSI R6950 Twin Frozr III Power Edition/OC successfully I launch MSI Afterburner, unlock the voltage control as "extended MSI" set the "graphics processor type" to 1150mv, power Limit is at +20, configure the clocks to what a 6970 would be; 880/1375 and is stable while gaming and on Heaven Benchmark.

Now the problem is that any core clock higher then 880MHz becomes unstable (video drivers resets/game locks up ) and also I can't increase the voltage (I will not bother to play with the memory clock until I get a stable core clock).
So I do the logical thing and raise the core voltage to 1.200v and set the core clock to 900MHz and is still unstable.
I was about to give up hope to overclocking the GPU when by checking with AIDA64/HWMONITOR/HWINFO/OHM notice that the core voltage on load/performance NEVER changes from 1.150v even when is set to 1.300v on Afterburner and it the voltage monitor in AF is does show 1.300v (Using the Catalyst 15.7.1)

Things I have tried:
Changed back to "silent mode" with the BIOS switch of the GPU (which is the stock bios, not unlocked) and I have the same problem as described above.
AMD Uninstaller and do a clean install of all drivers.
Uninstall and Reinstall MSI Afterburner and changing around every single option in AF, nothing works.
Even went as far as doing a clean install of Windows 7 to no avail, the same problem persist. (Same drivers)

 

[jaggerwild]

Did you unlock voltage adjustment within the AIB setting/general??

I have attempted multiple times to flash both of my 6950 cards with 6970 bios files with no success.
The program states that it flashed successfully but system will not boot after flash. Only when I switch to backup will the system boot.
I have both a Sapphire Radeon HD 6970 2 GB DDR5 and a GIGABYTE Radeon HD 6950 DirectX 11 GV-R695D5-2GD-B 2GB 256-Bit GDDR5 PCI Express 2.1 x16 HDCP cards.

These are the ones I have duplicate issues with.
Any help?

You have to realize not all HD 6950s will work with HD 6970 BIOs

good morning, i have mod my bios 6950 with rbe and i think work fine update shader from 1408 to 1536

 

[m4gician]

Hey everyone, new here but just finally getting around to updating my old rig. I put in a Powercolor 6950 1GB. How do I proceed with the mod?

I tried using GPU-Z to save the bios, then opened RBE and selected the radio button. I win-flashed the bios I saved after I checked the radio button, but GPU-Z still showing the 1408 number for the shaders. Is my card locked or did I do something wrong?
