[Jaskanwar Singh]

(red circled)

i push them, compress but still not able to get them out!

[topgear]

I think you need to open them from the back side though I'm not very sure about this.

[Jaskanwar Singh]

i tried TP, but couldn't

Hi i have follow all the instructions you have and its fascinating thbat my Sapphire dual fan 1gb 6950 is unlock already. Got the 1536. I need to ask if I need to use RBE and getting a atiwinflash? and also want to ask if what is the recommended power supply for OC the 6950? Its very good topics you have. Thank you so much.

[avinandan012]

No, you do NOT need to use RBE and ATi Winflash now because your card has unlocked already to 1536.

Recommended power supply? Seasonic S12II 520w or 620w.

hi I did already unlock the shaders to 1536. then when I OC it to 6970 speed using the sapphire trixx and then OC it as well in msi after burner then use the msi kombustor to check if its stable then it happened that I cant move the mouse anymore and it stucks and cant either ctrl+alt+del. Also when Im playing Battlefield 3 or starcraft 2 after 15 minutes I can see some flickering color in the screen and it exitsmy game. then When I play the game again my screen have different colors in it. What would be the reason.

[Skud]

Run the card on stock speed (with unlocked shaders) and report back.

most HD6950 that have locked shaders are not locked on purpose. instead AMD could have those as HD6970 at lower price. some of the GPUs are defective and the bad transistor section are locked. so even if you successfully unlock the extra shaders, there is no guarantee GPU will run stable. over that you overclock the GPU. run at stock speed. if everything works fine, switch the second bios (hence unlocking it to HD6970) and check for stability. avoid overcloking an unlocked GPU/processor. and even if you do, be ready for all sort of fireworks.

also if you want to check for stability, run some graphics heavy game. or run a game with everything max'd out.

[mrradeon6950]

Im actually running battlefield 3 at max settings and at unlcok shader 1536 but at stock speed of 800mhz/1250mhz. and it works fine. but when I sued the sapphire trixx to OC it to 880/1375 then the problem starts and it gives me flickering color and it exits my game. and when I run some benchmark like MSI kombustor it just went out of power and I need to plug it out then turn the PC again.

[rchi84]

Well I guess either your psu is running out of juice or the gpu on your card is one that needs more volts to run at 880 mhz. See if you can use afterburner to raise the gpu voltage to around 1150.

But make sure your psu is upto the task and your fans are set at 45% or more before you do this.

I guess u r getting artifact when ur gpu is oced, lower down ur gpu clock speed, or else it could damage ur card. BTW what is ur gpu temp during heavy games ?

[mrradeon6950]

When I play battlefield 3 in max settings including 8x msaa and 16x anistrophy and skyrim the same settings in 1080p resolution. Playing it for 8 hours. I have a max temp of 74c in HWmonitor and in MSI afterburner. this is under 800/1250mhz. Im using silverstone ST60F-P 600watts. I cant change the gpu voltage.

Temperature is fine.

Don't overclock to 880/1375 if you get problems.

Either keep it at stock i.e. 800/1250 or overclock to something around 830/1300.

[Jaskanwar Singh]

yeah, your gpu might not run stable at 880/1375 without extra voltage.
you can overvolt using sapphire trixx.

and remember to up fan profile before over volting.

[mrradeon6950]

Thanks!! I will try that and check it.

[Jaskanwar Singh]

^BTW its VRMs already stressed with addition shader load. dont overvolt too much IMO.
is someone able to find some nice links in this regard?

If i were nt wrong, u r talking about unlock/tweak the 6950 to 6970, am i right ? If yes, go to guru3d forum, and search for ' dave's ' article regarding unlocking this gpu. U can find a sticked article in there. As i know he is the 1st person who unlocked this gpu.

^i want some info on overvolting unlocked 6950.

Congrats Jas, Awesome Job with your card. Now Enjoy Doing Hard-core Gaming.

[Mr.V]

you can overclock the GPU clock but dont overclock the Memory clock much as it may cause instability.

Unlocked Sapphire HD6950 Dirt3 Edition

Just recently picked up a Sapphire HD6950 Dirt3 Edition. So far I am very pleased with the card. Shaders unlocked with the bios switch flip and it is a pretty solid overclocker as well. 970/1370 @ 1.18v stable
