what is the model number of your card?
if its part #21188-00-40R then its unlockable.
if its part# 11188-00-40R from newegg and everyone else seem to be getting it now. will not unlock.
also if its a non reference's card then it will also not unlock

Is this card unlockable?
http://www.newegg.com/Product/Product.aspx?Item=N82E16814150518

I am still not sure how you tell before you buy???? I was thinking of two of these in Crossfire water cooled. A new SB build.

THANKS!

Stock cooler - Check
2GB - Check
Looks like it is a rev 1 and you have an unlocker there. I think they should unlock just fine. If you really want to make sure call them up and ask if they have the bios switch on them because that means yes right away.

But all signs point to yes from what I see.

What can i do to increase CCC limit with HD 6970 Bios? I know i can change MSI Unofficial Overcloking but that messes up power saving features.

AB is very, hmm incredibly flaky with a full 6970 bios.

Here:

You can use my file and edit it to fit your needs.

Not sure about 5xxx series yet, as I don't have one available for testing.
Link:
http://www.techimo.com/forum/graphics-cards-displays/256789-enable-higher-overclocks-ccc-reg-entry.html

EDIT 03/14/11:
While the program to do this automatically is being tweaked, the codes below are for a 6950 and 6970 only, as it includes correct "default" clocks for CCC OD.


A lot of people seem to wonder how to enable higher overclock limits in CCC Overdrive without forcing it via a 3rd party program, so I finally got around to doing some testing to find out what reg entry needs to be done to enable higher OC limits in the CCC.

If you have no clue what to do in the registry, do us all a favor and stick to 3rd party apps. smile.gif

First, this has only been tested with a 6950, both stock Sapphire, and one modified with an Asus BIOS for 6950 w/ unlocked shaders.
I’ve tested with a fully fresh install, as well on an existing install and it worked fine every time.
I don’t have a 6970 or any other 6xxx or 5xxx series card to test, and as usual DO AT YOUR OWN RISK!

What I wanted was to have the option to enable higher than default overclocks, without resorting to a 3rd party program to do so, and for those wanting high Asus SD oc’s they no longer need to have an Asus card to do this.

On a fresh install of a stock HD6950 (GPU-800, Mem 1250), the OD limits are as follows:
GPU-840
Mem- 1325

Doing this single entry in the registry changes these to the following:
GPU- 1620
Mem- 2500

Yes, these are insane speeds no one will get close to, but now you have all the room you want.

Doing this mod also allows 3rd party programs such as Asus Smart Doctor, MSI Afterburner, and Sapphire Trixx to start out with higher default clocks being available without having to enable any “unofficial overclock settings” or editing config files and pasting in disclaimers. smile.gif

The mod allows the following default oc’s in the following:

MSI Afterburner beta 7:
GPU- 1215
Mem- 1625

Sapphire Trixx beta 3.03:
GPU- 1200
Mem- 1800



Now before skipping to the reg entry needed, please continue to read as this has some important info in it to explain things.
The entry will be placed in one spot, BUT, that spot is slightly different from computer to computer.
Also, this was done on Windows 7 64, I haven’t had time yet to try XP, and don’t have/want Vista.
Also, as stated, this was for a 6950, but I suspect a 6970 will work too, and possibly any other 5xxx or 6xxx AMD/ATI cards that have the Power Play function available.

When I was playing with things, I noticed that there are a few reg entries that don’t get deleted when the ATI drivers are uninstalled. Driver Sweeper (2.8.5) misses them, and so does CCleaner.

The entries all exist under the following keys:
HKEY_LOCAL_MACHINE\SYSTEM\
Under any of the following sub keys:
ControlSet001
ControlSet002
And any other ControlSets with numbers after them, and also in:

CurrentControlSet


Below each of these entries will be the following key:

\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}

For example:
HKEY_LOCAL_MACHINE\SYSTEM\ ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\ ControlSet002\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}

The “4D36E968-E325-11CE-BFC1-08002BE10318” is the important part, it has to do with display adapter info.




Now here’s one of the important parts:
The entry only needs to be done under the CurrentControlSet entry, but there’s a reason why I listed the other ones.

Below one or more of those keys are sub keys labeled “0000”, and depending on your computer may also have entries labeled 0001, 0002, etc…
These entries have info on the current and possibly a previous video driver.
Also, on the 4D36E968-E325-11CE-BFC1-08002BE10318 entry, you’ll see a sub key called “Properties”. Leave it alone, you’ll probably get access denied if you even try to view it.
This registry key is a key part of Windows, SO LEAVE IT ALONE.
The sub keys, 0000, 0001, etc are what we are looking at.

I suspect on some installs these sub entries could be what causes strange glitches and install issues for some people, as it appears the driver or CCC reads these keys, as this is where it gets the OD info from.
On my test computer I did a driver uninstall, used Driver Sweeper (2.8.5) and CCleaner, then after reboot I deleted all the 0000, 0001 keys, under each of the above example keys, then upon reboot, Windows “found” new hardware and created new entries for the standard vga adapter.

Once I see what the next hotfix does I’ll do a similar method on my primary computer before installing the new drivers.

Anyway, after a fresh driver install the only thing I did was disable AMD’s annoying “phone home” of the CCC, and confirm that the max OC in OD was 840/1325. I didn’t unlock the OD at this point, no need to unless you want to use CCC to control overclocks instead of a third party app.

What you want to do once the drivers are in is look for the following reg entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}
Under this will be at least one key named 0000, and possibly others listed as 0001, 0002, etc..
What you want is to expand any or all of those.
One of them, will have a bunch of other sub keys including some or all of the following in them:
ATI WDM Configurations
DAL2_DATA__2_0
Settings
UMD
VolatileSettings

This is the key you want.

Example on one of my computers:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000

This subkey, 0000 has all the sub entries listed above.
If I click on the 0000 key, there is a ton of info on the right hand side which pretty much details all of your cards settings.

This is where we want to add the entry.

For me I created a text file (saved it as a reg file) that reads like this:

NOTE: for now, this is for a 6950

Basically you are adding the “PP_PhmSoftPowerPlayTable” entry into that 0000 (or whatever yours is) key. When done it is now listed to the right.

A quick reboot and voila, the CCC has new OC limits.

Attached is a pic showing the entry.

Now I know this was winded, so I hope it makes sense. Due to the type of entry that is, it’s a bit easier to create a reg key to merge, than try and manually create that entry and all the data.

Feel free to copy and paste the above reg data, just be sure to modify it if your stuff is in a sub key other than 0000.

Hi guys,

I just received my PowerColor reference card from Amazon, and am happy to report it unlocked well to a 6970. biggrin.gif

I would however rather have it run a mod 6950 bios with shaders unlocked, I'm not too keen on giving the card an overclock for many reasons, (primarily noise and heat, but also stress, plus I flip these pretty often and upgrade and will not sell a unit that has been abused). Anyone have a link for that 6950 bios with shader unlock? Or do I just switch back to the old bios now that the shaders have been unlocked?

You need to save your default bios and unlock it with this software.

When you switch back (using the bios switch) to default the shader will go back to 14xx. You need to reflash the card using your original bios. Unlock the shader then flash the card when the modded bios is completed.
