Download ATI Tool 0.24 (or 0.25
) Beta 16, or latest ATI Tray Tools, both disable the 2D/3D clock speed crap, so it runs rated speed all the time. Other than that, I don't know what will work.
ATi Tool .25 Beta 15 is what I used. It looked solid for a while but I caught a glimpse of it changing back to 500 on full screen/window toggle. And for the gents with nothing to add, I'm not interested in overclocking just getting the advertised 575MHz without changing my usage habits.
ATi is being oh so useful as well, no name calling like our super cool trolls but your typical automated reply instead.
Guess I'll see if ATi Tray Tools is more consistent than ATiTool. Thanks.
