No, negative means only that validation is skipped. Which typically should never. It's more for testing than anything else. I haven't encountered a card yet that has more than 250000 as minimum frequency.
(II) RADEONHD(0): Power Management: Known Good Configurations (II) RADEONHD(0): 1 680000 kHz / 800000 kHz / 1.200 V (II) RADEONHD(0): 2 110000 kHz / 405000 kHz / 0.950 V I use Option "LowPowerModeEngineClock" "168750" for 2D & Xv without any problems. And even AtomBIOS table contains value lower than 250000. Do I understand my 168750 won't be valid any more and driver will refuse to use that, until I force it using "-168750"?
As the algorithm to determine the minimum frequency is neither trivial nor officially recommended by ATI, I thought it would be a good idea to allow the user to override the detection.
