How to enable additional shaders on Radeon HD 6950

[Sqweekie]

@ postumus
Maybe try through the device manager and upgrade driver for the standard vga driver and lead it to the unpacked ati driver ?


Anyway, I ordered a Sapphire 6950 , will get in thursday evening and will try to flash it than will post with results.

 

[postumus]

Haven't tried it in safe mode, but will try that next! I was thinking if editing the driver inf would work to support this device id. But safe mode sounds a lot easier to do. I've tried resolving other problems with registry cleaners, but never had any luck, is there one you can recommend Yidaki?

Dual 6850's

hello. i have dual xfx 6850's.

First off, if i do this flash and something does go wrong latter on (like years). would this void my warranty? would they even know if the card completly failed?

Also, how do i flash both cards? do i set both to option 1 then flash away?

or should i pull one card and do it one at a time?

also, does anyone know the safe max temp? i have seen some people hitting 92c with this unlock. is 92c safe?

 

[Yidaki]

This is for 6950!

 

[inerax]

This is for 6950!

DOH!!! lol... Thanks!!

 

[acousticdank]

still a good question. I know the technical answer is yes, doing this could void your warranty, but let's say you mod it then revert both switches back to original, would they void it? Would they even know? Isn't that the whole reason there is a switch?

DOH!!! lol... Thanks!!

I just purchased both cards from newegg. going to see if i can return them and get dual 6950's...

When i get the cards can i flash both at the same time? or should i flash one at a time?

i was kinda stupid when asking how to flash the 2nd card.. eventually i got it working...
weird thing tough...
in 2D i get artifacted on black backgrounds and stuff... and when entering a game/benchmark/furmark i get artifacts for like 20 seconds and than when the cards get "calibrated" they get away(the artifacts) and everything works great (even on 920/1440 clocks)
any idea ?

edit : for 2D artifacts to get away i need to lower the memory clocks to 1250~

hi, can some1 help me with that ?

Probably better to do one at a time so you can test that both are working.

hi, can some1 help me with that ?

I had artifacting with the 12a hotfix driver, reverting to cd drivers fixed it

Whats the best way to deal with testing? and timing? I've done some tests, but I need more input to make sure i'm doing everything correctly like I should.

Mastorz, did you unlock one card at a time then crossfire? did you have any problems?


what kind of temps are you getting?

anyone know what max temp is safe?

 

[postumus]

Just a small update, the drivers from Saphire's site install fine, but the drivers from AMD's site don't. Very strange, but the results from GPU-Z (1536 shaders) and Heaven point to this being a 6970 with a 6950 slapped on it, so I guess I lucked out (so far).

I guess no need to unlock for me then.

It sounded like fun too, like my old 9500 > 9700.

I'm curious as to why the artical hasn't been updated with those who have failed to get it to work. There are at least 2-3 people that couldn't get it to work due to it crashing after the bios flash, or artifacting.

please email me, i'm not monitoring the forum replies here. it's hard to keep track of both email and forum at the same time, so i changed the article to just "email me".

If you like to try, I can modify the original XFX6950 bios directly for unlocking the extra shaders. Just post the original BIOS of your card , or send to me , I will do the modification for you.

Hi there, my BIOS is the one seen here. I did a binary comparison to the one I saved before flashing and it's identical.

Appreciate the help.

So ideally what we need is a 6970 BIOS with 6950 memory timings? Are there any BIOS editors for 69xx yet?

Flashed successfully my Sapphire 6950, Running at 6970 stock timming, thanks you Wizzard ! Btw anybody can show me how can I use ATI video converter please ? Enabled acceleration in CCC but dont know how to use the CCC to convert video or such. Thanks.

OK , here we go.

Not recommand other 6950 users to use this BIOS, unless you sure your original 6950 bios identical to this one.

 

[Eluder]

Seems to work so far... thanks.
So how did you find out what is required to unlock just the shaders, very intriguing.

Wrong clicked the thanks button , but anyway you've managed to get new shaders including keep the memory/core speed stay still, gratz

I have a NOOB question.... What program do I need to open the .bin files and read/edit them???

Do you mind to do the same also for the Saphire 6950? I'm gonna try one and checking the users reports it is one of the most used. I'm more happy having the stock speed and the freedom to overclock it.

Thanks.

x2 for the Sapphire 6950 bios !!

Thanks rui0317!!!!!!!

Saphire 6950 BIOS.

I had build a small utility to do this BIOS modification, beta testing stage. You guys can DIY the 6950 BIOS for you own card by using this utility.

Thanks!!!
