rivatuner and x1900xt

hi!!!!

i just start with a safe overclock on my x1900xtx but i apply it and nothing happens. the core and mem stays the same.

i also clicked the startup overclock that seems fine, but then, when i reboot, not overclock is made again.

what can it happen???

PD. i disable atitool, ccc, ati hotkey poller and atismart in services.
i use ati tray tool.

any suggestion????

thank you

Does Rivatuner support the x1xxx series?

dan

i think it does. they say it in the web.

still waiting for help...
