I'm using 5.2 and the newest Riva build. When I set an overclock on my X800XTPE, once I run 3DMark, it reverts back to default speeds. Any idea what causes this? Happened in 5.6 as well. I know temps aren't the problem.
Use RivaTuner's hardware monitoring module and examine clock frequency history graph instead of overdrive
I have been using it. Riva shows the clock fine, but as soon as I run a bench, it reverts. Overdrive pic was just to show off temps (currently, Catalyst Control Center is not even installed). Speaking of which, 15.5 shows subzero temps better than earlier versions.
