GUIDE TO HOW I HIT 101HZ ON A RADEON 6970.
Ok folks. This is by no means scientific. Large parts of it have nothing to do with making 101hz work. In fact, it may be just 1 step required to do it. But this is what I did. And it works. I turned it off and back to normal mode, then back to 101hz several times and it works now. It just...works.
Here's how you do it: Powerstrip. Now...when I first got my monitor, Powerstrip did not allow a higher refresh rate to work. Maybe it's the new version that allows it to work. So all you may need to do, is download the new version of Powerstrip, and Voila. I'll get to that in a second. Here's a list of things I did:
1) Installed demo of latest power strip 2 weeks ago. Didn't work. Uninstalled it.
2) I then tried the Force DVI/HDMI Res/Refresh method using Phoenix and MonInfo (http://www.sevenforums.com/tutorials/7947-force-dvi-hdmi-resolutions-refresh-rates.html
) This was a great non-success. Windows 7 didn't seem to accept the created inf as a valid driver for the monitor. So I gave up on that.
3) Did ToastyX's method of using CRU. Had a lot of difficulty but got it working. But ended up working. After exporting the settings, I'd have to unplug my monitor for a few seconds, plug it back in, and the new refresh rates would show up under windows screen resolution/monitor info change. Highest I got it working was with these settings:
Now...I don't know if any of what I did above contributed to somehow unlocking the 101hz potential or if you can just jump into Powerstrip and git 'er dun.
4) I set these settings in AMD's CCC:
- Running AMD Catalyst 12.2
- NO Overclocking of the video card (doesn't mean you can't do it...I only had success with no overclock) So leave "Enable Graphics OverDrive" unchecked for now.
- Set LCD Overdrive ON at 200% (doesn't affect the hz, but makes games/videos better imo....even though the monitor already has some overdrive mechanics in it...you can leave it off if you want)
- Set Enable GPU Scaling at "Use Centered Timings" or "Scale image to full panel size"
- Set "Reduce DVI Frequency on high-resolution displays" (while playing around...sometimes it would work with it off, but it would always work with it on.
- Set Color Temperature Control to "Use Extended Display Identification Data (EDID) as ON. This, if nothing else, automatically fixes that "green tint" you hear a lot of people tallking about.
5) I may or may not have installed an older version of PowerStrip 3.80.625 then imported the attached registry key below (that you should rename to .reg.....though I don't think that matters, tbh) into regedit
regkey.txt 0k .txt file
THIS IS NOT FOR PIRACY REASONS. THIS DOES NOT EVEN GIVE YOU A WORKING COPY OF POWERSTRIP. AND YOU HAVE TO RUN IT, THEN UNINSTALL IT AND REBOOT YOUR PC. This step likely does NOT EVEN MATTER in the process. But I'm listing all that I did to be safe. You can google search a copy of Powerstrip 3.80.625 on google. It's just a demo so it's not piracy.
6) After uninstalling and installing the latest version of Powerstrip, my screen gave me crazy scanlines. I opened up windows screen resolution changer, and set my refresh from to he 82hz it was set to, to a lower refresh rate. 75hz in my case. Everything looked clear. IT IS FROM THIS POINT FORWARD, ALONG WITH THE SETTINGS IN STEP 4, THAT I BELIEVE ACTUALLY CONTRIBUTED TO HITTING THIS REFRESH RATE. EVERYTHING ELSE IS PROBABLY STUPID. THE FOLLOWING SHOULD WORK FOR YOU: Now exit Powerstrip, then run it again as an Admin. Rightclick the Powerstrip icon in your system tray, go to Display Profiles, and Configure. In the Refresh Rate section, there's a lock symbol. Make sure the button is Pressed In. Then go to Advanced Timing Options. And this is what I have for my settings on that screen:
With the real-time adjustment option on you can fine tune everything. But all I did was enter in the 408 pixel click, hit the up arrow once or twice, clicked in another box, and it updated all the settings including refresh to the appropriate numbers. Once that worked, I hit OK and I was done. The next screen should just look like this:
Keep in mind that Powerstrip now manages your resolution/refresh rate. So it will not show you the proper refresh rating in the windows resolution change screen. How can you know it's really running at 101hz? Well...windows feel smoother. You can also...run fraps on your desktop and depending on how much movement it is, it'll shoot the framerate up to 101fps (ie. while moving a window erratically across the screen) or running a game with Vsync on and seeing it hit 101fps.
I hope that works for you. Let me know if it does/doesn't and your experiences. And hey...if I got you 101hz on your Radeon card...feel free to rep me.
