Da gibt's den "Artifakt Tester".
Keine Ahnung ob der noch aktuell zum downloaden ist. Hab zumindest keinen Link gefunden. Vielleicht hast ja mit googlen Glück.
Hier mal die readme:
Taking Valid Artifact Measurements:
The following steps should help in taking valid
artifact measurements. Remember that Artifact
Tester is a synthetic way of measuring artifacts,
and does not compare to artifacts you may get
in "real life" gaming, working, etc. These steps
should be taken on a clean system with the best
drivers for your video card.
Steps for a valid artifact measurement:
1) Overclock your video (core and/or memory)
4 mhz higher than currently. If your
system locks up after freezing
2) (This step is optional, but recommended)
Restart the computer with the overclocked
settings. Make sure that no other programs
are running, except essential programs, like
3) Run Artifact Tester. To be completely sure
that you have absolutely no artifacts, you
may want to run both the Software Test, and
the DirectX7 test set to Hardcore.
4) If no artifacts are detected in either test,
go back to Step 1.
5) If artifacts are detected, lower your video
clock by 1 or 2 mhz, and go to Step 2.
Continue lowering your clock speed until
Artifact Tester reports no artifacts.
6) You have now found out your video's clock
speed limit. Enjoy your new overclocked
