    Good find UZ7, I didn't notice RacerX got the power tune limit to 50% for 69x0 cards, I suspect it was originally introduced by the sapphire toxic HD 6950, did you notice any positive results using it like scoring higher 3dmarks at 950MHz+ on the core? I will probably end up trying it myself was just wondering if you had any results to share. Thanks for posting.


    Further info about increasing powertune to +50%

    lol, naw RacerX doesn't have power tune limit I just edited the registry for that one. The only difference I saw was probably from 0->20% and that was with furmark, as for 20%->50% they were practically the same at least from my end.

    20%

    Clocks can be increased with Afterburner like this:

    1. Make sure Unofficial Overclocking is disabled
    2. Edit the shortcut on the desktop by adding -xcl at the very end of the target line
    3. Start Afterburner using the recently edited shortcut
    4. Message will appear that a reboot is necessary due to clocks having been extended
    5. Re-edit the shortcut removing the "-xcl" from the target line
    6. Reboot: After rebooting you will notice that the clocks in CCC have been extended allowing Afterburner to function without enabling Unofficial Overclocking

    Like allways, do at your own risk

    Ah I see, well I also posted a link to a post by TimoX (creator of RacerX) in my last post where he also explains how to get the powertune limit up to 50% when using his utility.

    Looks like it doesn't doesn't do much for 3dmark11 though, maybe I'll try it anyway, just for the giggles ;)

    I the only one reaching 1.5GHz on the mem (6950-6970)? :p

    Also, would any one care to make a 0% powertune vs +20% powertune in 3DMark 11?

    I would, except mine just locks up at the "combined test" loading...

    Hi guys,
    Thought i'd ask here!

    Maybe someone could help me out.
    I went from a x58 chip, to a Gigabyte Z77X UD5H board. and since the swap of boards and cpu, i couldn't get the card to boot on switch 1 to get my 6970 back..
    After some research, it's common on the Z77 boards for some reason.

    I found another guide, as some i used a while back wouldn't work on my new board, it would just be blank screen!

    So what i had to do, was Save the orig 6950 bios! then opend ATI RBE. then loaded the 6950 bios, and then clicked on the additional feature, then click on the 6970 shaders count, then saved the bios. and then flashed that BIOS to my 6950 using winflash to unlock the shaders. but seems like i havn't unlock it proper. the mem and core should be on 6970 default, like it used to be on my X58 board! also to get the 6970 ram and core, i had to up them in msi after burner. anyone got any idea how i can get higher clocks! as it seem i can't go any further.

    Cheers :)

    One way to extend the clocks further is to follow this:

    1. Disable unofficial overclocking mode if enabled
    2. Disable gpu overdrive in CCC if enabled
    3. Right click on the desktop afterburner short cut to access the target line
    4. Add "-xcl" without the quotes to the end of the target line.
    5. Double click the short cut and a message saying that the clocks have been extended and that you will need to reboot will appear
    6. Reboot
    7. Remove the "-xcl" from the target line of the afterburner short cut

    You are good to go.

    Hi,
    I added the -xcl at the end of the target line, like show below.
    I then clicked on the short cut, but nothing happens...
    if i click apply a message comes up shown below.
    I'm using after burner 2.2.1 and 12.6 beta drivers which i like...
    Am i doing something wrong ?

    Cheers :)

    Yeah you forgot the "-", also there needs to be a space between the quotation mark and the -xcl in the target box.

    It should look exactly like this:

    It worked :)

    Thanks alot guys!
    Just one thing. seeing as all i did was unlock the shaders! is this a 6970 now?
    As the default clock and mem are still showing as 6950 specs?
    And if being a 6970 now, it would push higher then say a 6950?
    Also whats a good clock to aim for?

    Thanks once again guys :)

    Because only the shaders are unlocked, your clocks are still at 6950 speeds.

    Seeing as can't unlock them to change the dafault, does this mean it's still a 6950 or is now a 6970?

    Cheers man.

    After you add -xcl close AB then reopen it, should get message asking to reboot the PC. when you open MSI AB again your clock limits should be extended.

    Lol!! i know that :) but what i mean is, i thought the default clocks on the 6950 would change to 6970 spec at the bottom of gpuz. still only shows 6950specs. it used to change to the default 6970 clocks on my old x58 board.

    so even tho i have unlocked the clocks now, (but still showing 6950 specs in default) i can clearly say it's a 6970 now ?

    do u understand me now ? :)

    Cheers man :)
