Frequently Asked Questions

ATITool is made to run on all version of Windows XP Home/Pro, Windows 2000, Windows 2003 and 64-bit editions. ATITool is not made to run on anything older than Windows 2000. Support for Windows Vista is in the early stages with some users reporting success.

ATITool is made to overclock all ATI VGA cards newer and including the RADEON 9000, but should work with older ATI cards as well.

ATITool does to some extent. It is able to render and detect artifacts on some nVidia cards, but it is only able to overclock nVidia based cards using the newest beta versions. This approach is reasonably stable at this point in the development cycle.

It is recommended that the latest DirectX 9.0c is installed. It is able to work with older DirectX versions, but without rendering.

It is recommended that the latest Catalyst version is installed. ATITool should still work with the older versions.

Most people recommend running it for at least an hour to find the maximum overclocks. Others will say let it run overnight and then test for stability. But it is really up to you to figure out how long you think it should run.

One key factor in deciding how long to run the tool is your cooling system. The basic rule is to start the tool and monitor the video card, cpu and motherboard temperatures. Immediately upon start up of the tool the temps will start rising due to increased load on the video card and cpu. Motherboard temps will rise more slowly and are largely based the ammount of air flow in your case.

Once you’ve started the tool continue to monitor the temperatures and look for them to stop raising and level off. The amount of time this takes will vary considerably from system to system and could be anywhere from 30 minutes to several hours.

Also, the room temperatures will affect temps inside your system. So, if you are after monster overclocks then crank down the A\C in your place and don’t worry about the cost. If you live in a cold climate then open a couple of windows and let the cold air reach your pc.

In any event, no damage should be done by running the test longer at default settings, even overnight if possible. This will allow the tool to thoroughly diagnose the cards performance and stability and result in more stable overclocks then a shorter test run.

This is because ATITool is not made to work on anything older than Windows 2000.

The first thing you should do is uninstall the Omega Drivers then install the official ATI Catalyst Drivers, if that doesn’t help report here with your problems.

The first thing that you need to do is disable the 3D Profile, this should fix most of the problems. If this does not work, please post your problem on the forum. You may also consider moving the cards speeds closer to the factory settings.

The clock frequencies on the Radeons are set using a divider, so only certain “steps” are possible. So, to get as close as possible to a desired frequency and have as small steps as possible, it changes the reference divider around. But, the problem is, there is only one divider for both the Core and Mem so if you change the Core divider to get closer to the desired frequency, the Mem frequency changes a little bit as well.

Because ATITool has found artifacts with your current clock speed. Often this is related to inadequate cooling of your case or high environment temperature.

Be sure that you have good case cooling. If the problem is not heat-related you may just need to adjust the speeds manually. ATITool may find artifacts at lower speeds that you cannot see on the monitor.

To be as close as possible to the desired clock speeds, ATITool variates the Reference Divider of the clock generation circuitry on the video card. The problem with that is, this has a small effect on the other frequency (memory if you’re setting core, for example). While ATITool tries to minimize this effect some users might want to disable this altogether – that’s what this option is for. The X1000 Series uses a completely revamped clock generation system, where the two frequencies are not linked at all, thus the reference divider locking is never necessary there.

When ATITool is running Find Max Core/CPU, Scan for Artifacts, or the 3D View, it uses 100% CPU, but when the 3D view is closed, ATITool should use hardly any CPU at all.

You have more than likely set your Core/Mem settings too high. To fix this all you have to do is just restart the computer (in some cases turn off) and it should be running fine again.

It doesn’t go away even when lowering clock frequencies! Find Max. keeps going down and down and does not stop.

On many cards, when you set speeds beyond a certain memory frequency something goes wrong with the memory chips/controller and display corruption occurs till the next reboot. Playing with the delays in the settings might help, or use the clock safety feature to limit the memory range ATITool is setting frequencies in.

From a software perspective there is absolutely no difference between R350 and R360. All registers and features are identical.
Yes, ATI tells us that R360 has improved features (better shaders and Hierarchical Z support), but these are either at the driver level, or non-existent.

ATITool bases the R350/R360 decision on the card’s device ID. All 9800 XT cards are reported as R360, all other 9800s as R350.
