#1789217 OS X Mountain Lion Install Guide for Dell XPS 17 L702x Optimus

Posted by wen1 on 25 January 2012 - 12:50 AM

I got my L702x 3D laptop working fully with nvidia. Given that i have a 3D laptop i had to take a slightly different approach. I even created an SSDT for it and applied a speed stepper patch. I think i have most of the pstates working. my geek bench score is 9545 http://browse.geekbe...ekbench2/548572 Looking at your geek bench score, there a re still more tweaks needed for SSDT but it is close. Attaching my SSDT for reference. But do not use this unless you have a i7-2670QM CPU. SSDT i believe is tied to your CPU. I can see the p-states hitting the turbo speeds of up to 3.0 GHz. I did not see it go to 3.1 GHz, which is the max for this CPU. Don't know why. Thanks mahesh for your links. Seems like there are lot of convoluted steps for creation of SSDT out there. But i finally found a specification document for sandy bridge processors and calculated the P-states myself. Attached Files  SSDT-2670qm.aml.zip 519bytes 175 downloads

Yes it is a combination of those three kexts and DSDT Reach out to mald0n at this thread http://www.insanelym...howtopic=235523 Very helpful guy. He created the DSDT for me. Here is the tool you run on your laptop, it creates a zip file on your desktop and upload it to his thread. http://www.insanelym...p...st&id=81816 Wen1, how did you get the audio working properly? through DSDT? I'm at complete loss when it comes to DSDT. I don't know/understand how to extract mine nor how to read/edit it. Any help? Only ask about Audio because i installed the kexts and im not getting it to work. You install all of them in System/Library/Extensions/ or Extra/Extensions/
