How to enable additional shaders on Radeon HD 6950

[fullinfusion]

Sorry, I have no feedback 4 you, NameonPrime. My cards unlocked, so my experience does not relate to yours, as our cards already behave differently.

Frankly, i unlocked, but no OC here for 24/7...only for benching. I do not play any titles that need any OC.

Gech Dave, where's the fun in that?

HIS 6950 unlocked to full 6970 and Cross/Fired to boot heheheh, Im showing 99.9-99.8% scaling with these kids
Max core and mem clocks under stock volts.

Impressive... Most impressive.

Those are some handsome overclocks, both CPU and GPU's! Looking good at stock volts (1.175 from a 6970?).

Well guys,

as i've said before i've ocverclocked my gpu to 910/1375 @ stock 6950 voltage, when playing crysis 1 on the first level, (first few minutes of gameplay), @ max settings @ resolution 1280x1024 (my monitor) it runs bautifuly.

when i push it to 920/1375 @ stock 6950 voltages and play crysis 1 on the first level, (first few minutes of gameplay), @ max settings @ resolution 1280x1024 (my monitor) it
hangs up/crashes after a few minutes of gameplay

so i guess i've found the point where the oc is unstable and so i've dialed it down back to 910/1375
@ stock hd 6950 voltages

but i notice in fullinfusion's recent posted pic in ccc it shows the unofficial clocks
where as when i go above unofficial oc the clocks in ccc disappear only leaving powertune
and fan control sliders.

Is it okay for me to say that i have an extremely lucky card to be able to run those clocks @ those voltages?

What do you guys think?

Software used:

Windows 7 Ultimate 64Bit
Catalyst drivers/control center/ 11.3
MSI AfterBurner latest version ?2.1?

My gpu
sapphire hd 6950 2gb non-reference

Thanks man, the gpu is stock volts under full 6970 unlock... MSI AB is useless to me. Having twins hooked up its a no go till they sort out the x-fire issues.

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".

Thank you very much!.

yeah

well it seems this whole thread is just choosing to ignore my posts
(i dont know what i did)

so you guys wont hear from me again, i wont bother you guys again

P.S - thanx for the little attention you paid to some of my posts

Hi

I have an Asus HD6950 DirectCU II 1GB.
http://www.asus.com/Graphics_Cards/AMD_Series/EAH6950_DCII2DI4S1GD5/
Is it possible to unlock it?
It has the bios switch and i have tried to flash both bios-es
but no luck. It flashes but after restart it still shows 1408 shaders.
I guess it is unlockable or im i doing something wrong?
I have tried to mod my stock bios with that mod batch and with RBE
but still no luck.

Also i have problems with that card.
Sometimes it just doesnt show any picture after reboot.
It was like that before i got flashed it and it still is like that now.
I have to take card out of computer and but it back, then it starts correctly.
Switching bioses wont help either, only card out-card in helps..

Heres link for my original bios:

I am also wondering the same thing do you have this card. Execpt, It is the 2gb version.

Yes, i have same card but 1GB

Yes, i have same card but 1GB

I just bought one of these after I sold my ref 6950, but I'm not sure I am going to keep it hell of a card.

Just ran the batch file and its unlocked one of my graphics cards (both XFX 2gb 6950s), how do I unlock the other one?

Many thanks,
Ash

Take out the 1st card and replace with 2nd card. Do the same thing for the 2nd card that you did for the 1st card. Should work out just fine.

Instead of crying about it you might want to take note this is a 100 page thread.

If its that important to you start your own.

Don't try to act like some victim that needs pity.

Was looking for a method without having to mess about removing hardware, incidentally I found this which worked a treat:

Copy the batch file, then edit it using Notepad. Look for the calls to ATIWinFlash.exe, there should be two:

ATIWinFlash -unlockrom 0
ATIWinFlash -f -p 0 <filename>

Replace the 0's with 1's

ATIWinFlash -unlockrom 1
ATIWinFlash -f -p 1 <filename>

I think I heard that way would work too. When I did mine, I did it one at a time. When doing it one at a time, you can test it and make sure it works just fine before going straight to crossfire.

are those the reference or non-reference :0

Hi guys. Bought my Sapphire reference 2GB 6950 month ago, and finally decided to flash it. First I flashed to 6970 bios with 880/1375. It ran okay, even benchmarks are no problem. However, I started getting random shutdown/restart after couple days. And as I do more research, I realize I can achieve the same performance with modded shader 6950 bios. So I flashed back to original 6950 bios, then flashed to 6950 modded bios. now I have 1536 shaders with 800/1250. I heard that with stock voltage(1100) I can get up to 900/1350 stable. But when i tried to oc at 880/1350. my comp freezes at benchmarks or games. So do I HAVE to adjust the voltage or is it different cards may have different results in oc. Thanks
Currently using 11.4 catalyse and oc'ed with trixx.
Btw. Am I gonnna damage my card cuz I flashed back and forth the bios?

With the shaders unlock only, how can you get it to past 840mhz in CCC? I've heard you can use MSI AB... but when I installed that program I noticed the speeds and voltages are limited to the 6950 bios settings (max 840/1325)... Can anyone point me towards the information I need to OC my 6950 without flashing to 6970 bios???

 

[kangaroodan]

Hi, tried this with the package you'd made for people inexperienced in this kind of thing (I am definitely one of those =D) and it worked fine, thanks! My card was a Sapphire one incidentally.

Look at my post #2394 on page 96. That should guide you to enable unofficial overclocking and voltage control in MSI AB. It works great; you'll be able to overclock nicely, even with dual card setup. I'm running both my 6950's at 900/1375@1.175v using AB.

There were people with non ref 2GB cards and 1GB cards that were able to unlock the shaders, like this guy:
http://www.techpowerup.com/forums/showthread.php?t=144537

But now it seems that many cannot unlock their shaders with a flash, so the bioses/bios's(?) must be protected. Unfortunately I don't have access to one to try anything.

Would it be helpful if I Saved out the BIOS from mine when it arrives?

Would you (or someone here) be able to compare it against the BIOS from a reference model to see if the shader mask is stored in the same bytes or not?

Is it possible things have shifted if the BIOS is slightly different and that's what folks with these newer Sapphire cards are having no luck unlocking the shaders?

 

[lauri_hoefs]

I have an Asus 6950 Directcu II an I've tryed to unlock it through RBE and Wizzard's script, in bot cases GPUZ recognised the 1536 shaders but I could not appreciate any performance increase between original and unlocked. running al 883core and 5300 memory I get around P4950 3Dmark 2011 in an I5-760.

Is that the GPU score, or the total score?

Modded and running the core at 840 my GPU score in 3Dmark 11 went to 4812 from 4576, while the total score only went to 3820 from 3726. (latter scores being with stock clocks and un-modified)

So the total score doesn't actually show the increase in performance as clearly.

Out of curiosity I also tried the 6970 BIOS, the GPU score went up to 5104 with 6970 stock clocks. But as I have no real need for the added performance, and wanted to make sure that the card runs stable, I chickened and flashed back the original unmodded BIOS

At the same time using geeks3d GPU caps viewer I can see only 1406 shaders while gpuz shows 1536...

I think I ran into this on another forum, but could not find the posts anywhere, sorry.. But anyway, there were at least a couple reports of GPU Caps Viewer showing a wrong shader count, so that should probably be ok.

Did anybody have performance increase unlocking a Directcu II? if so, please send me your bios because I've played so many times with mines (1 and 2) that I'm not 100% sure I keep the original one... (I know, this is too bad, shamo on me...)

If the original BIOS is lost, there are some saved in the VGA BIOS Collection:
http://www.techpowerup.com/vgabios/95388/Asus.HD6950.2048.101222.html
http://www.techpowerup.com/vgabios/95927/Asus.HD6950.2048.101222_1.html

Those should both be original and unmodified

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

How exactly would you run this?
I just purchased a 6950 twin frozr iii with dual bios and I'm trying to unlock it. :]
Thanks in advance for any help.


Also, for some reason apparently my IP got banned. Originally I was going to PM my question to W1zzard in the morning, but I had to rush to work and I didn't have an account, and just now when I signed up for these forums and went to his profile I got this message.

Sorry. The administrator has banned your IP address. To contact the administrator click here

I wouldn't be asking this here if the link I'm supposed to click wasn't dead. :/

Greetings. I received the card today and installed it.

Here is the stock BIOS from the Sapphire Radeon HD6950 2GB non-reference model 100312-2SR (see attached). In case anyone needs it, and more appreciatively if anyone can examine it and compare it against a reference model BIOS to see if there are any changes that would explain why we can't seem to unlock the extra shaders on this model card.

Thank you in advance.

Did you read the beginning of the thread? there is all the info you need to flash your card.

Download THIS It has everything you need to flash back n forth.
