The ATI tool 0.27 is working fine for me except of one thing: It stores the 850 Mhz for the core in the profile, but when I load that profile, the setting is set back to 837 Mhz. I know that the tool often goes down to a suiteable value if needed, but normally the one that can be SET is also be able to be stored in the profile and being set again by loading that profile. So the 850 Mhz core is the only setting I must set manually every time bacause the profile that stored the 850 Mhz sets 837 Mhz instead. The graphics card (ATI mobility Radeon 2600 XT) however runs very well with the 850 Mhz core clock. Am I doing something wrong perhaps?
