Sapphire HD 6950 1GB unlocked to HD 6970 1GB!

[Jaskanwar Singh]

Card Used/Needed -

SAPPHIRE HD 6950 1GB GDDR5
SAPPHIRE HD 6950 2GB GDDR5
SAPPHIRE HD 6950 2GB GDDR5 Dirt3 Edition

Stock Settings (I am using a 1GB version) -


A Little Story Behind -
I had overclocked my card to 900/1275 and was going to overvolt to get further. Before that i decided to read some user experiences at newegg. Saw this -

Bios Switch unlocks 6970 shaders.

So thats how the fun began.

How to Unlock -
1. You need to have a Sapphire HD6950 with a dual fan cooler. 1GB or 2GB both have good chance of unlocking.
2. Make sure the card is running at stock 800/1250.
3. Turn off the system, open the cabinet side panel and locate the BIOS Switch on the card. Its near crossfire bridge connector.
4. Flip the switch towards right.
5. Reboot.
6. Open GPU-Z and you shall see this hopefully -

7. Now you can overclock it to 880/1375 (the HD6970 speeds) (Note - Every card is different. Some cards may need overvolting to get to 880/1375. Overclock at your own risk)

My Overclocking Update -

This is at Stock Volt.

awesome stuff mate... wonder why this went unnoticed for so long... pic of the BIOS switch would help some members i think..

[Jaskanwar Singh]

thanks rajan.
bios switch is too small buddy. difficult to get good pic. tried.

[kapilove77]

any chance for me to unlock?

[Skud]

This is killer! Some benchmarks would be helpful.

@kapilove77: MSI had released a BIOS and instructions to unlock the shaders earlier for that card. Google it.

[Sarath]

Haha 6970 users burn in hell

Oh wait!

On a serious note nice little tutorial up there. i wish there was such a trick for 6970 users too but nvm

[Jaskanwar Singh]

thanks sarath.

UPDATE -

[sam]

@jassy, congo man. free gift. lucky

[Skud]

What about noise? I have read this card is noisier under load (just like other dual fan cards). Even my single fan's noise is audible at 50% and above in winter when the ceiling fan doesn't spin.

[mithun_mrg]

^^ i think the noise even if it will be during gaming which is easily overtaken by the speakers/heaphones u use
congrats jas

[Jaskanwar Singh]

@sammy
yeah, thanks buddy

@skud
yes card becomes noisy with high fan profiles. i used trixx fan bar to test this.
but i use headphones, so not a problem.

and we cant give away oc due to noise

@mithun_mrg
right. and thanks buddy

Yours is the story of luck, getting a 6970 from a 6950 1gb, that too a RMAed one.

nice going mate ... now time to play with HD6970

[Cilus]

Jas, superb work buddy. You are becoming pro day by day. Now you got a HD 6970 from your HD 6950. So I don't think you need to puch the card much further.

[slashragnarok]

Does this card have 2 6 pin connectors or 6pin+8 pin?

[DARK KNIGHT]

It's answered here:

Of course, it won't be just a flip of switch, you have to actually flash the BIOS. Else there are scripts to do it automatically. But beware, this might be risky and there's no guarantee. In any case, always backup the original BIOS.

@Jas: pure luck here. Enjoy your unlocked 6950.

What is the worse thing can happen while unlocking my card?

[Skud]

A bricked card at its worst and no extra shaders if there's nothing to unlock.
