domeproject Posted April 16, 2007 Share Posted April 16, 2007 yeah..that`s sad . Anyway i guess that we cannot direct drive the cpu clock or the multiplier somehow....let`s say for rxample a powerstate with multiplier 5x (1GHz) instead of 4x (800 MHz), or to fix that bug somehow...Is there a chance that a future OS update to fix it and allow lower powerstates? That would be useful for real macs too, i think, they really have issues with heat and battery life... Link to comment Share on other sites More sharing options...
battle_clown Posted April 16, 2007 Share Posted April 16, 2007 afaik and from what i've understood from the discussions between neill ( who did the original acpicputhrottle ) and the forum the problem lies not in apci or direct drive, but in the fact that mac os uses the cpu clock to calculate the duration of some timers that determine the behavior of the GUI and with clocks lower than 1 ghz the algorithm used by apple is severely messed up due to some thing that has to do with a multiplication of something with something else and a factor "20". well, i THINK i remember that way. if you are interested, search all the posts by neill douglas, but it was clear at the time that either apple could fix it or it would not be possible to have powerstates below 1 ghz.

domeproject Posted April 16, 2007 Share Posted April 16, 2007 I understand now. Thank you a lot for your patience Seems like i have to stay with the cpu at full thrust or alternatively disable one core for 30 mins of battery life :censored2:. After all this is what makes the system so fast comparatively to windoze :censored2: Hope i woun't burn anything, it's a laptop tough Link to comment Share on other sites More sharing options...
