Overclocking 7900GTO In Vista 64bit

[jbloggs]

The problem I am having is this, I am using drivers 100.65 (also tried 158.18) and when trying to O/C it with Rivatuner, on the actual O/C pane the "Test" facility does not appear, so when I set a new clock, I cannot "test" it first before I set it.

How can I get the "Test" facility to appear in Rivatuner, or is there another O/C utility that works correctly with Vista 64bit?

I have no problems O/C the 7900GTO in XP.

Many thanks for your comments.

Only overclocking tool I got successfully to work with vista and my nV cards was nTune.
