pierret Posted October 23, 2006 Share Posted October 23, 2006 Hi all, I've successfully installed 10.4.6 on my X2 4600+ with ECS KN1 SLI Lite but it stutters. To fix this problem I had to use cpus=1 kernel flag. From what I gather this flag forces the OS to only use 1 core. Couple of questions: 1. Is it possible to use both cores with stuttering? How? 2. If using only 1 core, would that make the CPU to overheat on one core and eventually damage the CPU? Thanks Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/ Share on other sites More sharing options...
Gio Posted October 23, 2006 Share Posted October 23, 2006 Yes I have the X2 4800+ and I use idlehalt=0 which causes the cpu not to really "halt" or rest so it might make it more warm in there but I havent noticed much difference I should go download a temp monitoring program for OS X and see if it differs from when I run Windows. I'm using air cooling as well so its not very efficient at cooling.

pierret Posted October 23, 2006 Author Share Posted October 23, 2006 I tries idlehalt but that did not make any difference. Do you use that flag with any other flags? Is there a difference between iddlehalt and cpus?

joe75 Posted October 23, 2006 Share Posted October 23, 2006 I have also read idlehalt=0 is for AMD. On my core2 I use idlehalt + cpus=1. I tried without the cpus=1 and it was slow and jittery, not as bad as with no flags, but still not right Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/#findComment-215014 Share on other sites More sharing options...
Gio Posted October 23, 2006 Share Posted October 23, 2006 Oh, well just idlehalt works like a charm for me no stuttering or lapses in time(typing, video, music, etc.) Sorry to hear it didn't make a difference for you. -Gio Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/#findComment-215024 Share on other sites More sharing options...
joe75 Posted October 23, 2006 Share Posted October 23, 2006 I think its an Intel problem Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/#findComment-215028 Share on other sites More sharing options...
Gio Posted October 23, 2006 Share Posted October 23, 2006 Isn't OS X native on Intel architecture I think it should run with less flags not with more. Oh well hopefully the projects on the new kernals and EFI will succeed in making things easier. (I just downloaded the qemu EFI and it doesn't boot all the way but it gets real close - hangs at extensions then goes to all grey screen) Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/#findComment-215033 Share on other sites More sharing options...
pierret Posted October 23, 2006 Author Share Posted October 23, 2006 Since we have to stick with one core for now, is there a way to chose which core to use?

Also use search button in forum. Link to comment https://www.insanelymac.com/forum/topic/30999-amd-x2-dual-core-and-cpus1/#findComment-218134 Share on other sites More sharing options...
wesley Posted October 27, 2006 Share Posted October 27, 2006 This problem is SO not going anywhere. You know this sig of mine's been this way since last November or so? Heh. Some people have it working with idlehalt=0, but my system, as well as lots of others, needed to resort to cpus=1.

Darth OS X Posted October 27, 2006 Share Posted October 27, 2006 Yea I had to reinstall osx and this time I have some stuttering sometimes with only idlehalt=0 but I don't want to have to resort to cpus=1 and have only one core. Also my first install of osx didn't ever have to use anything then all the ones after that have been downhill. and yes I'm the same person as the above poster with same avatar I just wanted to change the name and couldn't find how so I made a new one.

If using only 1 core, would that make the CPU to overheat on one core and eventually damage the CPU? Thanks 1. Idlehalt=0 and downclock the CPU multiplier together works. Also you can increase the FSB in order to do not lose cpu frequency, in this case you have to adjust memory ratio to do not have system lock-ups like here: http://forum.insanelymac.com/index.php?sho...mp;#entry199818 Also to use both cores you have to install SSE2 kernel, SSE3 makes cpupanic. In my case I did not notice overheating or heat problems. 2. In this case you can use SSE3 but you have less CPU performance. Disabling one core doesnt damage the cpu since is not set by hardware level, only OS is not using one core, also is not affecting cooling or overheating. This problem is SO not going anywhere. You know this sig of mine's been this way since last November or so? Heh. Some people have it working with idlehalt=0, but my system, as well as lots of others, needed to resort to cpus=1. Hey Wes, give a try to what I wrote here....... actually is not Apple's fault, Windows users have stuttering too, it seems is a CPU arhitecture problem.
