I have an X1950XTX but for some reason it will not go into 3D mode (3D = 650/2000, 2D = 505/1200) for one of my games (LotRO). Is there some trick I can do to force the card into 3D mode? The help forum for this game has not helped ("Buy a GTS" was the most useful answer I got...). All of my other games work fine.
 
open up ATi tool, and ATi tool will automatically make it in 3d mode, while ATi tool is open, open up the game you wanna play in 3d mode and hopefully that will work
 
You could try installing ATI Tool. When launched it switches the card to 3d clocks and forces them to stay until it's closed (it disables the ati poller temporarly).

This is a solution to your problem (might not be the best one...)

Edit: seems i was to slow to answer... lol
 
Where is this option? I have the latest version installed but I do not see any sort of "Run in 3D mode" option. I have the hotkey poller enabled as I am not OC'ing my card. The last time I tried disabling the hotkey poller my card stayed in 2D mode no matter what.

As I said before this only happens with LotRO and all my other games work fine. Maybe the "hotkey" that is normally polled is missing or something in the current client...
 
Once you start up ATI Tool it should switch automatically to 3D clocks. Then as long as ATI Tool is running it will keep the 3d clocks active (it should if no default settings have been changed)
 
What I do:

Turn off the ATI Poller service.

Install the LATEST ATiTool.

The default profile is 3D clocks with 2D voltages. That's no good.

Create a new profile, call it "2D", "Cold", something telling you it's your non-gaming clocks. Set the clocks to 505/600. Open "Settings", then go to the "Voltage Control" menu in the drop down. Set "VGPU" to 1.175v, MVDDC to 2.083v, MVDDQ to 2.080v, and VDDCI to ~1.350 (exact setting doesn't matter within ~0.1v). Click "Save", then select the profile you just created ("2D", etc.) To to the "Fan Control" menu in the drop down. Select "Override Fan Speeds", then select "Fixed Percentage" and set it to 37%. I find this the perfect balance between temperature and noise, though you can adjust it accordingly. Again click "Save" and save it to the 2D profile. That's your 2D settings done.

Next, go back to the main screen. Create another profile and call it "3D", "Hot", whatever. These are your gaming (i.e. 3D) clocks. Set the clocks to 650/1000. Go back to the voltage control. Set "VGPU" to between 1.400v and 1.450v (the exact value doesn't matter much). Leave the other voltages alone, they're fine. Save it to the 3D profile. Next, change the fan speed to whatever you want. Leaving it at 37% keeps it quiet, but for me the temps it reaches gaming (mid to high-80's) are too high. I personally go for 68%. Again save it.

Now, you can either use ATiTool to change the profiles manually whenever you go into a game, or you can set up 3D Detection, which automatically detects (or lets you select) programs that it will change modes for. To do this, go into "Settings", then go to the "3D-Detection" drop down. Enable it, and select your 3D profile for the first one, and your 2D profile for the second one.

That's it, you're done!
 
Good stuff. Thats just what I was hoping to hear. Is it possible to run Catalyst Suite and ATITool together? I'm wanting to use ATITool to control fan/temp, etc... but use Catalyst suite for adjusting anti-aliasing, etc...
 
Yep they do. Thanks for the help!

One odd thing though. My temps went up about 3-4 degrees after installing CCC. Perhaps CCC is putting voltages up slightly?

Also I don't really like to see my gpu get over 60c. In fact mine usually doesn't get hotter than 56-58c during gaming. But the fan usually ends up running around 68% to maintain those temps. Am I being unrealistic about just how cool I should keep my gpu? I'm pretty sure the CCC software doesn't keep the gpu this cool. And I really don't care for how loud the fan is.
 
Yea, don't worry about it. Mine goes up to 70-75 degrees under load. These things are designed with temps up to over 100 degrees in mind. 60 is fine!
