I imagine I could remedy this by setting separate 2D/3D profiles, but I was just wondering if this is a common occurrence. Sorry if this has been covered, but 370 pages is a lot to dig through.
Edit: Just to clarify, that's actual voltage as measured with HWInfo, not just the targeted volts shown in AB.

Did you check whether it clocked back to 500 MHz or 300 MHz when idle? I think the difference in voltage is in those clocks. In AB I find setting 925 MHz core prevents it from clocking back to 300 MHz so my unclocked profile is 924 MHz. I can't find a reason as to why it is doing this.

I assume that is the P score you are talking about. That score is highly CPU bound. I think you will see a closer to 100% gain in graphics score.

Got a question (well, a couple really)... Will swapping out a powercolor 7970 bios for an unlocked Asus 7970 bios work? Need a voltage unlock...

I've done some overclocking here and there on CPU's and I've always used the standard CCC for overclocking the GPU and haven't learned much about graphics overclocking. I have a few questions but it would probably take weeks to sift through all 371 pages of this thread for answers, so I'm asking lol.

I really want to overclock this card in order to squeeze a few more FPS out to hit 60 in eyefinity at 4x AA in most of my games. I'm so close but I can't get a stable overclock without being able to increase voltage (right now I'm sitting at 1085gpu/1400mem). Heat will not be too terrible an issue - I've got a spare TEC laying around and plan to slap it onto my GPU with a waterblock.

Like I said.. new to gpu overclocking- so what is the best way to unlock my voltage? Where can I get what I need in order to do this?

Any and all help is greatly appreciated!

As soon as I posted I went into AB and checked and, sure enough, it's only checking down to 500 as opposed to 300. Hopefully that's something an upcoming AB update can rectify.

Oh this bug is miniscule. If only you guys were doing this back on Cayman, you'd be pulling your hair out cuz the problems were 10 fold.

That said is anyone running more than one monitor?

Ok color me congused. GPUZ says crossfire is available yet disabled. In CCC it says CrossfireX is disabled. I thought there was a difference between Crossfire and Crossfire X.

I have two of the exact same card, that would be crossfire correct? How do I make sure it's enabled and that GPUZ will see it?

I'm using CCC Powertune +20% and Trixx 1200/1800/1.2v. Sapphire Trisx will work with any brand reference card, I believe. The last 10 or so pages of this thread are very rich with O/C advice and example setups FYI. Good luck and have fun! :)

If you have another screen, monitor CCC and GPU-Z to see the second card in action when running applications in FullScreen Mode. You don't see it during idle because the second card is in sleep ZeroCore Power State.

It can't hurt anything to set CrosffireX to enabled in CCC though right?
post #3710 of 38704

I don't think we are on the same page. Please post a screen shot of what you speak of.

 

You are talking about application with CorssfireX disabled under AMD CrossFireX Mode for 3D Applications. You can not enable CrossfireX of the saved profile unless you create or modify it.

 

Under the drop down list: 

 

  1. Disabled. This option turns off CrossFireX multi-GPU acceleration.
  2. Default uses whatever the global system default option is, or whatever AMD has configured, if the game already has a profile in the CAP package.
  3. AFR Friendly, which is for games which generally work well with Alternate Frame Rendering (AFR).
  4. Optimize 1x1. This is another AFR option, but with optimizations for 1x1 surfaces. The idea is, if AFR Friendly has problems, Optimize 1x1 is another option to try.
  5. Use AMD Pre-Defined Profile allows us to select the CrossFireX configuration of another game and apply it to the one for which we are making a profile.
