How to enable additional shaders on Radeon HD 6950

Why not try modding your own bios to unlock shaders? That shouldn't be a problem for you.

Yes I did that the first day, but I want more overclock than 840.

So f I change vendor to assus in my bios, than smart doctor will work, and with smartdoctor you can increase your official overclock limit.

So the simple problem is, why i cant work with anything than my own bios(without changing vendor).

For some reason, like I said in my earlier post, both my Sapphire 6950's -after flashing them with the Sapphire 6970 BIOS- run stock at 900MHz (which was the speed of my Asus Matrix 5870 2GB, incidentally) and 1375MHz on the VRAM...

Haven't tried higher clockspeeds because of heat issues on the Assus Gene (LGA1156) mainboard (cards sitting right on top of each other)...

If you want to go over the clock restrictions of the Catalyst Center (which is 950/1450) you could use MSI Afterburner...

So using RBE, you tried to change the vender name to Asus? Someone said a while back to only change gpu voltages in RBE because that's the only that can be changed right now. Maybe that's the problem. If you want more OC room, you can edit gpu voltages and OC with Trixx. That's worked well for me lately.
 
Hi all!

Successfully flashed a HD6950 Sapphire to HD6970 using W1zzard's batch files (Winflash refused to erase rom in standard use) :)

Before:

After:

PowerTune +20%, no artefacts at all :)

Asus Rampage Extreme / E8600 @4460MHz / G-Skill Pi PC3-17600 2x2048 / Corsair HX850W PSU.

Thanks all for the good job :D And add to stats ;)

Thanks for the tip on Trixx, Manofthem... Didn't know Sapphire had tweaker software of their own... will check it out mate :toast:

I read somewhere that it is actually working.

I'm the proof kind of:p

Because the driver recognize the moded vendor and all was ok in 2d.
The 100% exactly thing happen with original assus bios, so the problem must be something else.

edit:

One stupid question:
RBE produces .rom, but for the wizzard script to work the file must be .bin. S
So do you just rename the file if rbe is used or what??

yes just rename the .rom to .bin and flash from there.
 
I need Atiflash 3.85 does anyone know where I can find it. I searched all over with no luck

Im using 3.79 atm and I get adapter not found when trying to flash in DOS...
even typing atiflash -i I dont get anything but the help info

Help
 
Nobody has flashed there 6950 in DOS?
winflash dont work, and I dont under stand what to type in CMD
 
Anyone here tried this mod?

Yes, I had to. The way to go is on the first page of this topic... ;)

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".

I've tried it on one card, and it works, but the performance is lower because that BIOS is from a factory 'overclocked' Asus 6950, not a 6970. Asus released an overclocked version because it's not a reference board any longer and the card can't be flashed.

I flashed my card back to standard 6950 BIOS and re-flashed it to the Sapphire 6970 BIOS, because my cards run at 900/1375 when flashed... I don't need CCC to overclock either...
 
fullinfusion said:
Yup, I got it to work. I was not thinking atm but W1zzard fixed the problem I ran into.
Now I can flash freely back n forth with ease :toast:

Congrats and good luck amigo :toast:
 
fullinfusion said:
Is THIS the bios that just unlockes the shaders but dont change the voltage?
Click to expand...

That looks like it since it says it's a 6950 modded to unlock shaders. Use that or just just the script mentioned in this thread earlier to modify your original bios.
 
fullinfusion said:
is there any thing I should know of about clocking this flashed gpu? anything to be concerned about?
Click to expand...

Not at all, Fullinfusion. This flash keeps core- and memory clocks at the reference level (800/1250) and only unlocks the shader amount, so there should be nothing to worry about...

There's of course always a certain risk, flashing a BIOS, but here, when a flash should go wrong, you have the 2nd BIOS and the possibility of re-flashing the primary BIOS to its original state...
 
I was reading somewhere that there is also a 6950 bios that unlocks the shaders, and they said that there are issues when you use the 6970 bios... anyone heard of or had any issues?

Im using the HIS 6950 shader mod only without the voltage change. Well it seems fine.

Im now on the Sapphire 6970 bios... clocked it up to 950/1400 and runs Mark11 without any problems. I think the issue was the memory isnt as good as the 6970 is from the factory.. 6950 memory is weaker I understand and dont like the added heat...

Yeah sence W1zzard told me what I needed to do, flashing takes about 5 seconds lol... now I can even flash in DOS mode so it's all good!

Plus ya gotta love the dual bios switch :rockout:

"Somewhere" and "They" are too vague to take into consideration. From what I've read on youtube, Gamespot, Guru of 3D and here, there's but a fraction of the people who flashed their cards to whatever BIOS wha have issues. And those issues are mostly due to wrong drivers or bad luck that the card doesn't accept the flashing...

Then you're better off than me... I can't overclock the cards (running them at 900MHz isn't a real overclock) as my computer locks-up the minute I go over 900MHz or increase the mem-speed over 1375MHz...

Canada gets the best cpu and gpus for clocking lol :p
How about using the HIS bios... The one that just opens up the shaders and not the volts?

Then use the newest beta ver of MSI Afterburner and up the core clocks as well as the mem clocks using the opened up voltage control...

Your going to need to edit the .CFG file in Afterburner using Note pad, but I think you should try it and see how it works... :pimp:
