How to enable additional shaders on Radeon HD 6950

[blaqsmith]

Well I guess I'm one of the few that can't seem to get the 6950 -> 6970 unlock to work with my new Sapphire 6950 card. I get the "Cannot erase ROM." error when using atiwinflash from the gui interface. Using command prompt to "atiwinflash -unlockrom 0" briefly pops up the atiwinflash progress bar, but it disappears after a quarter of a second with no apparent affect.

I've also tried the batch script, which I notice mentions that I'll have to "Click OK in the Winflash screen that shows up", but I never get this dialog, just a couple of atiwinflash progress bars as before, each disappearing after less than half a sec. I've tried it with the provided unlock.bin rom and with the Sapphire unlock rom.

"atiwinflash -i" also gets a brief progress bar that disappears.

I've everything tried in both position 1 and 2. Always running things as admin. No dice. Shaders always report as 1408 :\

I can save my bios with atiwinflash... this occasionally flashes the screen a few times then lock up. Reboot required.

Windows 7 64bit. Any thoughts on where I'm messing up?

Just make sure you're following this correctly and WITH the position on "1". No point attempting it on the "2", as that is the read-only BIOS.

Man I'm having the same issue with the Sapphire card I just bought from Microcenter. Tried flashing it EXACTLY the way listed by W1zzard, and no go. The progress bar pops up a couple times and then nothing, and shaders stay at 1408 every time.

Sucks =/

Yep, it's certainly in position 1 when doing everything. I've tried the instructions on that link to a T.

My card is from Newegg, fwiw.

My card is from Newegg, an XFX. I had to run CMD as Administrator. THose steps worked fine for me.

After "atiwinflash -unlockrom 0" the progress bar disappears after a second, it's just letting it be rewritten.

Then type "atiwinflash -f -p 0 unlock.bin", whereas "unlock.bin" is the bios that you want to load. Rename whatever bios you want to "unlock.bin" and throw it in the winflash folder. It should work out for you.

"atiwinflash -i" also gets a brief progress bar that disappears

That's not in the directions that were linked a few posts ago. Wonder what that's for..

 

[blaqsmith]

Of course, as soon as I post this, after testing and trying everything, I find the solution. I had my 6950 in the secondary PCI slot because it fit better in my small form factor box. After moving it back over to the primary PCI slot (a really, really freakin tight fit - presses on wires from the power supply), the unlock now works.

Just flashed the card successfully with an xfx, and after setting the card to 20% power it blew up on me. Poof, smoke, and one dead card. What are the odds I can RMA this?

Well the odds are that if the card has blown, they will not be able to tell that you have flashed it so you may be OK.

Another sucessful XFX unlocked here. I did use the regular unlocked bios with the script.
Piece of cake.
PS. Already sended a mail to W1zzard.

I did use the script cuz winflash was crashing my pc. Maybe becouse it was recognizing my old 3870 there.
Anyway, the flash worked.

It was 3DMark, Boinc, CSS and BFBC2 stable.
I got 1 BSOD in my first try of 3DMark. Then i instaled the update, set the fan to 60% and quit GPU-Z. Works.
3DMark still shows 6950.

Anyway, i got only 4946 points. My PC its a little old. I have an Q9450@3.4 with 4gb DDR2 1120 cas5. default 6870 clocks.
Huge performance lost in Couner strike source. 500 FPS to 150 with 8xAA 16 Ani. I think it is Probably a driver/config thing.
Any comments:

Hi - flashed my Sapphire but had to do it the DOS way otherwise I got the exact same as you. Down load the files into your User> and follow the instructions - the hardest bit for me was geting the Paths names right for the files in DOS!

Hi
I was using for over two weeks moded bios. Play games, benchmark and etc. Morning I turn on ghotic 4 and see a picture:


Such a picture is even worse in every game.

I changed the BIOS switch to 2 reinstal drivers, I have no idea what to do.

Can anyone help?

Edit:
I checked that the artifacts appear if the GPU is set above 50C and the fan speed is 50% and is currently well.
Maybe some other solution?

Is that 3DMark 11? I only have managed to get like 4897 points running that, so your numbers look good to me. Maybe I'm just running low then...
I'm running 1090t@4.0 and 8G DDR3@1600.

Should I be higher? If so, how can I get it higher?

 

[ClassicEnergy]

I just flashed my sapphire 6950. Everything went fine except that my amd overdrive tab is locked.

I noticed this even before flashing the card. Any suggestion?

looks to me like you fried the card but im no pro tech. my 5670 started looking like that a couple of weeks ago so i had it replaced

I need some help here!

just got this card Asus HD6950, so tryed to flash the Asus 6970 bios, got the wrong Id thing so followd W1zzard guid.

The problem is that the driver wont detect the card, in the device panel it just says Standar VGA adapter, even my screen aspect ratio is wrong.
Have tried to install the Catalyst sevral times, also uninstalled and so on.

Flashed it back to the original backup and still the same ((

in this condition its useless

need help, im stuck

 

[krousnik]

packaged the hd 6950 bios modding script.

www.techpowerup.com/wizzard/Mod_BIOS_HD_6950.zip

give it a try and let me know how well it works

This works perfect. Any chance to make a bios that can run core clock speed of 880MHz?
please

I had a problem, not exactly like yours, but I uninstalled the drivers, then used driver sweeper to delete all things ATI. Then after rebooting, reinstall. Could try it. It sounds like there is no driver installed from what you are describing.

 

[krousnik]

W1zzard, you can add another Asus 6950 to the list.

Unlocked absolutely fine using Rui's modded Asus bios. Currently running at stock 6970 clocks at 1.1v. Completely stable and haven't noticed any issues after a couple of days of benching/gaming.

Temp wise it idles 35-40c, however hits 90c in furmark with the fan on auto. Waiting for there to be a decent option for cooling the VRMs then i'll be slapping my T-RAD2 on there to see if that makes a difference.

can you paste a link on where can I download the Rui's modded Asus bios?

I would love to be able to do that too. It's too bad that you can't edit clock speeds with RBE anymore.

Ive taken my clocks back down to 800/1250 because I dont need the extra horsepower at the moment, plus the guy above has said his card developed those lines after 2 weeks modded

Maybe that's not a bad idea. Go back to stock and just OC from there.

flashed 6950

Has any one ran the furmark 3d benchmark test after flashing there card? mine freezes a little bit into it any one else?

 

[Kiwi7Kid]

Flashing 6950

update just played cod bo at 950/1450 after 5 mins screen went all screwed up noticed gpu was very hot what should i do ?

 

[telafidium]

Unlocked but unstable...

Powercolor 6950 successfully flashed to 6970 but having stability problem, no artifacts.

It reboots after 1min on fumark, crashes on Metro2033 but it's 12hr stable if it's idle on desktop or anything non-gpu intensive, it still crashes with 70% fan speed and under 80*C.

Tried it on 6970 and 6950 clocks but still unstable with power control setting on CCC to 20%


- now I went back to 6950 bios even with overclock and that's stable...
yes I flashed it with Powercolor's 6970 BIOS and I have 700W PSU...

What's the deal here guys it's unstable...? (like kiwikids post above I guess)

*edit using the latest catalyst preview for w7 x64, does that matter?
