Enable higher overclocks in CCC with reg entry

[RacerX]

haydent,
first, does the program work for you with default clock settings? As in will it adjust clocks correctly according to load and what apps are running?

Second, There are 3 clock speeds on these cards, If I read that right, you want to overclock the gpu in 3D mode, but heavily underclock the ram?
I doubt that will work, as it's probably too low of a speed for the ram, especially with the gpu running that fast.
If you're looking for some lower UVD clocks, you should be able to drop the lower limits, which relate to UVD clocks for things such as videos, etc..
For example, defaults are usually 500/1250 on the 6950, I set mine to 400/1100 and when running those apps, it runs them at the lower speed if that's what you want. I could probably go quite a bit lower, but I doubt it would matter that much. Reason being, i've run gpu-z while watching a video just to monitor things, and I noticed the clocks would fluctuate between 2D (250/150) and UVD (500/1200). Sometimes the card would even run something in between those, now at 400/1100 it doesn't go higher than that, and that middle speed is lower as well.

Using clock tweak what is probably happening is once the card kicks into 3D mode, the clocks go to the higher built in profile.

Hello. Great tool but my Sapphire hd6970 (keylock edition) had on power control settings -50 +50 limit after i run the tool went -20 +20 is there a workaround for this ?

????
Never heard of a keylock edition, don't even see it on the Sapphire website.

Have a link?

Second power control settings are -20/+20
I've never seen nor heard of one that goes up to 50.
Pushing a 50% increase in power would pretty much blow the TDP limits, which is why they put them there in the first place.


Do you have screenshots of the card installed with the OD panel showing 50 instead of 20?

[haydent]

clocktweak was only able to underclock the memory to 775mhz but i was recommended ati tray tools which let me go as low as i want , but too low effected my bitcoin mining speeds. so i use 450 mhz currently with 920mhz core. the lower mem clock helps lower temperatures and be more stable at higher core clocks.

i cant do any more testing as i corrupted my ccc and cant run it , reinstalling it doesn't help, it just locks up my computer straight away.

Yes here is the link of keylock edition : Maxishine • View topic - New Sapphire HD 6970 (Key Overclocking)

[fermthe]

So is there any way to make power control settings on ccc to go -50 +50 ?

[fermthe]

On Sapphire's site the card that i have is this : http://www.sapphiretech.com/presenta...n=&lid=1&leg=0

Which is a non ref hd 6970 and i had to buy a V2 waterblock from aquacomputer

I know you are still having problems with the 6800 series. Just thought I'd let you know that I am having the same problem as bandera did MINUS the BSOD. I ran the tool, restarted, and OD is gone. If it helps you pinpoint the problem at all CCC isnt the only thing that can't see the clock speeds. I decided to see if it affected anything else and started MSI afterburner. None of the sensors were working; both clocks said 0mhz, temp said 0, GPU usage said 0, etc. I purged the registry and everything works fine again. My card is the XFX 6850 (HD685XZNDC).

[RacerX]

fermthe,
thanks for the link.
No wonder I didn't see it at first, they just list it as a regular 6970.

It doesn't list anything special, and the CCC OD settings are designed by AMD.
have never seen or heard of anything other than -20/+20.

vegasgamer,
thanks for the info.
Yeah, i've been trying to figure out the 68xx series for sometime, but i'm stuck.
Until i can come across someone with an Asus 68xx series using SD, i don't see this tool working on them.

[fermthe]

Thanks for the response RacerX. The one i have is just non ref board with one less vrm. The only strange thing is that from the beginning from 11.5 to 11.7 it had -50 +50 on.

[RacerX]

Very cool!
Thanks for the pic, had never seen that before.

Some good news, I just took a look at the file and found a way to get the Slider to do 50.
Just tried it on mine and my OD panel shows 50 instead of 20.

Now I haven't tried running it it at 50, don't want to cook my card, but since you already had it at that I'll explain what to do to get it back.

First, disclaimer:
Do this at your own risk, that includes others trying to change it.

Do you still have the racerx.reg file on your desktop?
If not, re-run the tool and when it asks to save it, save it as racerx.reg

you need to add the .reg after the name or it will save it as a generic file, because after it creates it do NOT merge it.

Now, right click on it and click "edit".
This should open it in Notepad.

look down about 4 lines and you'll see the number 14 in between a bunch of zeros.
Carefully change the 14 to a 32, making sure not to change or add any spaces or extra commas.
Close it and let it save it. Then click on it and allow it to merge.
reboot, then CCC should have the 50 back for you.

Let me know how it goes.

[fermthe]

Thanks very much it works and you rock !!!

RacerX, sweet program -- thanks much for this!

Question -- is it possible to adjust the default values for the UVD mode? I have an XFX 6950 and I keep getting jumps into UVD mode when I watch videos online. It'd be great if I could set defaults for that, specifically memory values. I don't care much about the core clock, I just like to set my memory speeds all the same for each mode so I don't get the annoying screen flicker when it switches memory speed.

Also, not sure if this has to do with my 6950 being modded to 6970 bios, but my clocks seem to randomly jump back and forth between 2d and 3d, even when I'm not doing anything. Any idea?

[RacerX]

Could be a couple of things.
First, what OS and browser?

I noticed XP had a tendency to switch back quite a bit between 2D and 3D clocks back in the earlier driver days around the 11.1 or so.
The thing is though, it wasn't something I noticed unless I was using gpu-z to monitor it. Win 7 didn't have that problem nearly as much, but in the beginning AMD concentrated heavily on Win 7 drivers before doing much with XP drivers.

Also, depending on your browser what happens if you disable gpu hardware acceleration? That should solve the clock changes when watching videos.

That's one thing that I've never really experienced is the screen flicker you refer to.

other than 2D clocks, all the memory clocks should be the same unless the BIOS you used changed them.

I'm on FF5 now, and have gpu HW acceleration enabled and I don't notice any clock changes, unless I'm monitoring them.

it's possible the flash to the 6970 clock speeds and voltages is a factor.

Also I custom set my UVD clocks lower than default and don't experience any flicker problems.

Lower defaults are 500/1250 on the 6950 and I set mine to 400/1100 so on some of the video stuff it runs at the lower clock speeds.


Check the memory clocks on that BIOS you used to see if the clocks are all the same minus 2D speeds.

[Coldblackice]

Interesting, thanks for sharing and for the quick response.

I'm on windows 7, using both IE 9 and palemoon (FF5). The clocks were changing, however, even before FF was installed. That leaves IE, however, I had already disabled gpu acceleration and restarted. They were also changing while IE was closed, along with everything else. I believe the jumps would come from even simply switching to another window or another program, and then when I'd go back to the desktop, there would be like 4-5 residual "after-jumps", even with nothing happening or any use/movement on my part.

I've rerun the program and reapplied the registry tweak, setting all the 2d/3d memory speeds to the same 1475 value. I now no longer get the flickers while changing modes, as the memory speed never changes. That's what caused the flickering on my old 5850 as well, until I modded the bios to alwats keep memory speed static. I imagine the flickering has to do with having three monitors attached to the card, maybe it's a lot more of a "stressful" transition on the card to switch between modes when driving that many monitors.

Anyway, the flickering is taken care of, but the random switching isn't. Here's what's really weird, that I'd appreciate your opinion on -- sometimes the card will jump into some "halfway" mode of 775/1475 and will be locked there. What's weirs is that it's still using the custom memory speed I set (stock BIOS is 880/1350, I believe), but it's pulling that 775 from nowhere? Im guessing that maybe it's another mode already in the BIOS, but the memory speed gets overridden with the registry patch.


Would you mind explaining the technicality of how the AMD drivers are working together in collaboration with the card's BIOS and windows? I know these three work together, but I'm confused as to who has priortiy and who "calls the shots". For example, which one determines when the card should be in 2d mode or 3d mode? Once that decision is made, who gets final say of authority over which speeds area chosen? Is it what's set in the BIOS, what the drivers and profile.XML say, or what windows reads from the registry?

[RacerX]

I imagine the flickering has to do with having three monitors attached to the card, maybe it's a lot more of a "stressful" transition on the card to switch between modes when driving that many monitors.

Ok, that would be a key piece of info I needed at first.

Multiple monitors require higher clocks to run them correctly.

Also, are you running some kind of overclock on that? Memory clock is usually 1375 on a 6970, not 1475, unless that has a special overclocked BIOS on it.


The random switching is something that I have seen as well.
I can duplicate it running a video in media player. I can watch clocks with gpu-z jump to odd numbers as well. It doesn't affect the video or cause flickering problems or anything, it's just odd that the clocks bounce around.
Lowering or adjusting my UVD clocks cause new speeds to show up as well.

My best guess is it's something built into the BIOS for "energy efficiency", adjusting clocks in relation with demand on the card in UVD mode, since parts of a video play fine in 2D clocks, then they kick up for a bit, then back down, etc..


As for your last question, that's a bit of a tough one.
Here's the problem. With these latest cards they basically lock out the BIOS from changes to clocks and fan speeds. Adjusting either causes a digital signature mismatch which then causes the driver to basically stop, resulting in Windows hanging at startup, or a BSOD.

it used to be that the BIOS had primary say, but now, the drivers do.

The profile.xml file has some say, but only if CCC is running. In a driver only install, profile.xml doesn't even exist.

The simplified version is this.
Bios hands control over to driver, which then looks to the registry for additional info, as in our file entry in this case. Then adjustments are made to the card if it exists. then if CCC is set to load at startup, it will load, then read profile.xml

The thing is though, if you don't open CCC and go to the OD panel and adjust clocks or change fan speeds, the profile settings for clock speeds aren't really used. Neither are voltage adjustments.

My card I have 3D voltage at 1.200
Profile.xml lists it at 1.100 (default for 6950) even with CC running and playing in OD, my voltage doesn't get lowered, since running various monitoring programs will list the 1.2 voltage.

Bottom line is, AMD made it a pain for users to simply adjust fan and clock speeds without having to resort to 3rd party programs.

Since I can't stand the fan profile on mine, what I have done is set a shortcut for afterburner to load and start minimized, with only a modified fan profile. No monitoring of clocks or voltages. then I have 2 profiles set. One for default clocks, and one for an overclock.
Then if I want to game, i change the clock speeds and I'm done.
I also don't have CC load at startup. Tired of all the constant errors it writes to the Aceeventlog, plus the slow delayed startup, plus no fan control other than a fixed speed, etc....


If I gamed daily, I could use this tool to set my new default 3D clocks to my overclock, so upon startup, the fan profile would load, as well as my overclock from the reg file and I'd never have to click on anything.


Anyway, long winded explanation, but this should cover the basics of it.

Hi, I tried the racerXV16 and it did work for one of my 6950 but it made the other 6950 unaccessible in CCC and in crossfire.

Do you have any idea what I could do to fix this problem?

[bennmann]

I tried to use racerx v0.14 for my laptops 5870m (which is basically a desktop 5770). However I accidentally clicked "Overdrive re-lock" and now cannot get OD to show up again anywhere.

I may not have a profiles.xml backup, and when I reverted the registry changes that didn't bring back OD either. This is very unhappy for me. What can I do?

List all the specs and we'll see if we can figure it out.

Driver, card info, OS,etc...

Try v 0.16.

Also, to unlock it manually go here to the following reg entry:

HKEY_CURRENT_USER\Software\ATI\ACE\Settings\Dashbo ard\Graphics\Overdrive5

To the right it will be empty, or have a string value called TimeUnlocked

If it exists, change the data in it to something like this:
9/22/2011 2:00:00 PM


If it doesn't exist, create the string value named above, then copy and paste the date/time info in it as above.

If it worked, you can confirm by opening the racerx tool and it will list that info for date and time unlocked.
reboot, and you should be good.


Worse case scenario, a driver uninstall and reinstall should reset the prompt in CCC for you.

[bennmann]

Thank you very much, that brought it back. I will try 0.16 shortly.
