How to enable additional shaders on Radeon HD 6950

[Wijkert]

what script?

This one.

 

[Capla]

This one.

it's the same, didn't help. damn it I used to flash it yesterday, but when I try overclock CPU, my PC is stuck so I have to drop bios on motherboard with CMOS Battery. and then obviously bios in video card are erase to default. Now I can't flash it back to 6970. I don't know what is wrong now... sh.t

Did you run as administrator?

Is your graphics card in the first pcie slot?

Stop oc'ing cpu and gpu at the same time! how would you know which is causing the unstability?

Clearing cmos on the mobo will not effect the bios on the graphics card at all, it sounds like you are new to overclocking because that's not how to oc a cpu by clearing cmos each failure. Do one at a time and follow a guide for your system.

MSI Afterburner 2.1.0 Beta 7 is ready, changes list includes:

- the official support of GTX 560 Ti / GT 440.
- Now Microsoft Visual C++ 2008 runtime libraries are included in distributive
- Hardware database is now configured to force fan duty cycle monitoring to be performed via slower AMD ADL SDK path on AMD RADEON 4870 X2 and 5790 series cards
- Changed way of unlocking unofficial overclocking on AMD graphics cards to make overclocking newbies think harder before enabling this functionality blindly and coming to support forums with fake bugreports
- Added alternate unofficial overclocking path allowing keeping PowerPlay active on some modern ASIC families during overclocking
- Fan control settings are now being forcibly reapplied after changing the clocks via unofficial overclocking path to bypass bug in AMD driver causin the fan control settings to be reset to defaults after programming PowerPlay table

To enable unofficial overclocking in this version it is necessary to:

- Set UnofficialOverclockingEULA field to the following text: I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
- Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path

Yes I run cmd as admin of course! I have only 1 PCI-E slot. I try to flash via bios - atiflash didn't see adapter at all. try gigabyte vga_utility_atbios it can flash bios from the same VGA only. all is vain... I'am a little desperate now :shadedshu

 

[dulemk]

Try with
atiwinflash -unlockrom 1

If it shows something than ok.

Or maybe you should just try atiwinflash -unlockrom because you have just one slot.

P.S. But I don't know if that can make thing worst.

dev. number is 0 because its only one. it's not work too...

 

[JimmyJump]

dulemk yes, sure. I got no message at all in the program and cmd screen
here the vidio http://www.youtube.com/watch?v=lOx-tqsnduk

Have you made sure that the GPU's BIOS switch is set to the number one position? Mine came out of the box set on number two...

 

[Wijkert]

Yes I run cmd as admin of course!

If you use the script instead of manualy via cmd, run it as admin also.

Sapphire 6950 flashed to 6970 ! Everything is ok ! Thanks a lot !

hello
ive been reading this forum for a long time but now i need to ask you about something

i think using 6970 bios to mod ours 6950 card is unlocking something more than only shaders
i have triple checked it and now only need some confirmation

3dmark vantage last test called "perlin noise"
when im using 6950 with only unlocked shaders (clocks 900/1375) i got like 145fps, but after switching this to asus 6970 bios (same clocks) i got like 199fps
like i said i triple checked this and results are always the same
can someone try this and see if he got that big diference too in 3dmark vantage "perlin noise" test ?
ofc in other tests i got similar result on both modded only and 6970bios, but here 30% diference ? thats strange

"perlin noise - this feature test stresses the computing power of your gpu by rendering multiple octaves of perlin noise ..." ;p

ah noone can check this

I've try N2, N1 pos> don't work.

Juhu! Works like a charm here!

Finally ONE Tool for all:
Overclocking over CCC limits, FAN curve AND PowerPlay 2D/3D/UVD clocking!!!

I use Windows 7 with UAC turned off permanently, and when I use the "Run" command box, I always get the "This task will be created with Adminstrative Privileges" underneath...

 

[GSG-9]

Yes I run cmd as admin of course!

This may be a stupid question but have you clicked on the .bat file inside that download, clicked "run as administrator" and see if it worked? Sometimes people don't realize the .bat file is in the download.

pls. help me somebody! I can't flash my Gigabyte 6950 to 6970. "It says cannot erase rom" than I do all that mentioned in that post How to enable additional shaders on Radeon HD 695... I rename the bios file to unlock.bin, and when I run atiwinflash -f -p 0 unlock.bin nothing happens. why? it's completes in a half and with no messages

What is the exact type of your video card, Capla? If it's an originally factory overclocked edition, then you cannot flash the card as it has a BIOS which was already altered... Only original reference cards can be flashed.

 

[GSG-9]

...then you cannot flash the card as it has a BIOS which was already altered... Only original reference cards can be flashed.

What? Thats not true. Where do you hear things like that? ALL 6950 cards released before the soon to be released reduced price 1gb/2gb revisions will work.
I can't say if the 2gb cards on the egg right now will work, I would think they are still the old versions as the item number for the gigabyte card is the same as when I bought mine a month ago. I know the 1gb xfx will not flash.

Apparently currently shipping Radeon HD 6950 cards from all manufacturers - which actually are all the same card with different sticker - have their shaders locked via the BIOS method, so we can exploit it easily.

Some HD6950 2GB don't unlock their shaders:

The Asus 6950 doesn't let itself flash, because it has a factory overclock. Only cards with the reference BIOS can be flashed. Gigabyte has a factory overclock as well, so no reference BIOS, that's why I asked...

*EDIT*

Seems that the factory overclocked Gigabyte 6950 is a 1GB card, so Capla should be in the clear...

I don't trust that bjorn3d tried all the methods to unlock their 6950. Although it is a possibility that this is a NEW 2Gb (as said revision) model that can no longer be flashed. My speculation above is that some of the cards at new egg are still old cards. My logic being that the model number on the Gigabyte card at new egg is the same as it was when I bought my card a month ago, which makes me think they can still be flashed.

Yeah its all the new ones that can't; the next two months are going to be confusing for people unlocking these.

I have Asus HD6950 2GB with stock 810/1250 clocks and I have no problems with unlocking additional shaders although I did not use HD6970 bios. Still I'm damn happy about this card.

One question to you, guys: What is your max stable GPU OC on HD6950 with 1.1V on GPU (stock voltage)?

900 core for extended use, I don't oc my ram.

Can you give me a quick tip how can I set UVD clocks ?

 

[manofthem]

900 core for extended use, I don't oc my ram.

I couldn't hit 900 on stock voltage. I think I had to go to 1.15v.

Thanks man!
Now I am running with unlocked shaders and 890/1350 at 1.175 Vcore and custom fan curve, all within one tool!!! (+20% from CCC). Have been struggling until now with trixx, Smartdoctor, RBE and stuff - not anymore!

I have an ASUS6950(unlocked shaders BIOS), and the speeds above are the stock speeds for an ASUS6970.

It's probably not the max I can get for clock speeds but it is indeed very stable, and it really meets all my current needs.


Cheers!
