kramer2k Posted April 2, 2007 Share Posted April 2, 2007 It would have worked right off the bat if you would have followed the "How To" of 10.4.9 installs... but thanks for playing!

I have 10.4.9, CoreDuo, AppleIntelcpupower,... and I have both core enabled... so I think that it is not always needed... My toshiba started to work with both cores after a BIOS update Link to comment https://www.insanelymac.com/forum/topic/47283-intel-core-duo-dual-core-fix/#findComment-338924 Share on other sites More sharing options...
devilhood Posted April 3, 2007 Share Posted April 3, 2007 Homer, you misunderstand. Core 2 Duo and Core Duo processors work perfectly under any Intel compatible kernel. The only issue is regarding Laptop users. Desktop systems do not experience any stutter problems associated with these processors. Acer Aspire, IBM Thinkpad and Toshiba laptops seem to work fine with both cores enabled from what I can tell. Your advice would not apply to users of other laptops such as Dell Inspiron or XPS users. It's a BIOS issue for us Dell users and cannot simply be fixed by using the NoHPET kernel Core 2 Duo laptop users ALSO experience the stutter problems.

Spaces Posted April 4, 2007 Share Posted April 4, 2007 does this effect the pc?? because i have to boot my 10.4.8 with '-f cpus=1', and i loose about 40% of core power! will try now, great find!!

pandnaka Posted April 5, 2007 Share Posted April 5, 2007 Sorry it might be stupid question? How do I get my OS to show the procesor? I look in system preference but did not see anything about my processor!!

emig647 Posted April 5, 2007 Share Posted April 5, 2007 Pandnaka, Check /Applications/Utilities/Activity Monitor It's a great app! or you can install MenuMeters for more details about your processor(s) Link to comment https://www.insanelymac.com/forum/topic/47283-intel-core-duo-dual-core-fix/#findComment-340300 Share on other sites More sharing options...

Do you think there is any chance this might get fixed/resolved in the future?

Do you think there is any chance this might get fixed/resolved in the future? That depends on if Dell manage to write a proper BIOS that isn't a pile of sh$%. The only other way of it being fixed, is if the Darwin Kernel is altered to compensate for whatever the BIOS is doing. I seriously doubt Semthex will look into such an isolated case, especially when everything works fine with the cpus=1 flag, but you never know.

quasar_x Posted April 5, 2007 Share Posted April 5, 2007 That depends on if Dell manage to write a proper BIOS that isn't a pile of sh$%. AFAIK the BIOS isn't written by Dell from scratch. Usually they license a standard BIOS (e.g. Phoenix or Award) and just customize a few options. The only other way of it being fixed, is if the Darwin Kernel is altered to compensate for whatever the BIOS is doing.I seriously doubt Semthex will look into such an isolated case, especially when everything works fine with the cpus=1 flag, but you never know. Has it already been proven that Dell notebook are the only laptops that experience this problem? If the problem is related to the mobile version of core duo, isn't it more likely that also other laptop brands have problems? Even if it's "only" Dell, I don't think it's an isolated case, simply due to the sheer number of Dell notebooks being sold.

mourngrym1969 Posted July 5, 2007 Share Posted July 5, 2007 Just as an FYI to anyone that has the famous 'stutter' problem with Core Duo 2 procs on laptops... I have an HPET SSE3 compatible Core Duo 2 that you typically would not see a recommendation to remove the AppleIntelCPUPowerManagement.kext. Indeed, both cores worked fine UNTIL I had to patch the IOUSBFamily and use orBytes PCGenUSBEHCI to enable USB 2. Once I installed that kext, USB 2 worked, but I had stuttering and terrible overall performance. I disabled the 2nd core and it went away. On a whim, I removed the AppleIntelCPUPowerManagement.kext and re-enabled the second processor and voila! All was well with USB 2 and dual cores. Just FYI, Mourngrym Link to comment https://www.insanelymac.com/forum/topic/47283-intel-core-duo-dual-core-fix/#findComment-401806 Share on other sites More sharing options...
