Hi All, First ATI just released new drivers (8.35.5). Anyone have the energy to check whether they support powerplay on C2D MBPs (it only supports 2.6.20 on fedora but next month's release should support it in general - of course by then I'll have moved to 2.6.21 for dynticks)?
Here are some interesting links regarding the ATI drivers: http://www.phoronix.net/forums/showthread.php?t=1265&page=4 http://www.extremetech.com/article2/0,1697,2103630,00.asp It will be interesting to see phoronix's article on ATI's development cycle. An optimist might take some of the points made in the links above as a good sign. To the main point of this post. I have a C2D MBP and when I use it in Linux the fans are very active. I thought this was just a problem with the applesmc driver but its been suggested that the SMC controls the fans itself without the intervention of the OS and that the problem is just that Linux uses more power and generates more heat hence it needs more fans (though just looking at the temperature monitors this is not obvious at all). Another idea is that this is related to clocking down the GPU which can't be done yet on a C2D. I'd really like to sort this out since I don't think the machine was intended to be used with such active fans and I'm worried it will do it damage in the long term. So the question/poll is for those core duo MBP owners (but C2D owners should also share their experiences). Does your fan become active a lot (3k+ rpms and noisy)? Have you tried using power play and does it help? Has anyone actually seen improved battery life or power usage when using powerplay? I saw some people say that their wattage didn't change at all when using powerplay and this is very weird (even if the MBP CD's already have an underclocked GPU - powerplay still reduces the speed a bit on top of that). thanks, Sheer ------------------------------------------------------------------------- Take Surveys.
