Radeon HD 6950 shader unlock instructions

[the elve]

There is more involved than just making the USB drive the first priority (though that is needed), you also have to have the USB configured to be a boot drive as well. You'll have to google for the info it it didn't provide it with the directions (although it is possible to just flash the new bios onto the card outlined by the first post). The file called original.bin is the original bios, without the unlocked shaders or OC abilities. The other .bin file, r6950pex.bin is the one with the unlocked shaders and OC limits.

hey i tried the first method u told me since there is no need to learn how to boot from USB flash

but unfortunately i had a message after i wrote command of (atiwinflash -f -p 0 modded.bin) i think this i dont remember exactly i had a message said

rom programming failed.

any ideas?

Did you have the modded.bin file in the folder? And did you check with file extensions shown in the folder?

Oh yeah, if you wish to make it work with the r6950pex.bin bios, substitute "modded.bin" with "r6950pex.bin"

i substitute modded.bin into r6950pex in command

but also same message rom programmin failed and some loading bar is active

please wait flashing is in process it may take more than minute

did you type the command before that, the one that unlocks the rom, if it's read only?

Oh, you may also need to change your bios switch to the writable version.

the bios switch in my card?

its fan performance=silence switch i think

i did all the instruction
but smth went wrong is when i pressed save in winflash programme

it gives me a bios.rom file

not a .bin file

and when i change it to bin file it and pressing RUN.BAT FILE it said there is no bin file

sorry i cant explain my english is too bad sorry

This is due to you hiding "known file extensions". You'll need to go to your folder options, go to the view tab and uncheck the "hide known file extensions". Then you can actually rename the file to .bin.

Another alternative, is to save your bios from "GPU-Z", which will save it in a .bin format.

anyway i ve done it by the second method which MSI stated at their site

and i got more limits to overclock in CCC but unfortunately i still got 1408 pixels in GPU-Z

opinions?

That would mean that your shaders are not functioning. They may have lasered off the additional shaders, or they just don't function correctly. The limit to OC limits is actually more useful than the shaders are, all in all.

 

[the elve]

and that is an indicator of what?

i mean sucsess or failure

and what is the recommended overclock , voltages with AfterBurner utility!

thanks mate about valuable info

 

[the elve]

can some one plz tell me what are 24/7 overclock and best voltage

any exprience plz?

I've never overvolted my GPU. I just play them at 885/1375 clocks. My twin frozr can go much higher, but my reference card gets a little unstable over 900.

 

[the elve]

885/1375 without voltages modifications?

885/1375 without voltages modifications?

Correct. Actually, my TF2 can go beyond 920/1375 (I never tried higher due to my 2nd card being slower).

I grabbed the last remaining reference MSI(dual bios, stock cooler) from Newegg.

After just unlocking the shaders, my computer freezes. I can't virtually do anything as it locks up whenever I start an internet or any programs.

I flashed my bios back to the original. Do you have any ideas what is causing this? I RMAed my 6870 back to Newegg which costed me $50 in addition to restocking fee due to Canadian Post's strike. I didn't even OC. If shader unlocking doesn't work, I'm gonna cry

It does sound as if you got one that did not have fully functional shaders. You were able to unlock it, which was good, but not all 6950's had fully functional shaders.

You could try using the directions matto17sec's posted, but you'll likely have the same issue.

When I first unlocked it without any drivers, I didn't have any freezing problem but GPU-Z showed only half of unlocked shaders. After installing the newest ATI driver catalyst, it started freezing here and there, unfreezes saying "Catalyst was restrated due to an error" than re-freezes again in 10 seconds.

Do you think it is still my card's problem? Thanks!

It may be worth exploring a driver problem, but I doubt you'll find a solution. Normally when you unlock the shaders, you don't have to change the drivers, it just starts using them without problem.

I just saw a post on extremeoverclocking.com that took these instructions and are having varying success and even found some ways around the locked bios that some cards are coming with.

Look down the page for a truely adventurous method to unlock the bios.
