Thank you abs2004. Now I have installed and testing the one FB.kext from Leopard 10.5.8 (1.5.36.25) + Legacy SpeedStep injector (excluding all GPU references) + DSDT hack code X3100 injection = working great at moment. And well, Natit.kext seems to be not necessary at all, if the code inside is ported, I mean this is very easy to do by DSDT injection, see: The results by using the Legacy SpeedStep injector (MacBook4,2 fake profile = smbios.plist):

Thank you for replying.I don't add AAPL or X3100 code to the DSDT,so I need the Natit.kext.If not,it shows blue screen for death.I need to refer your DSDT

[mnfesq]

I'm trying out the Leopard 10.5.8 FB.kext to see if I have as much luck as you guys have had. I too do not need the Natit.kext since my DSDT has the X3100 fix. I am using the smbios for a Macbook 4,1.

I tried to remove the Natit.kext and hack the DSDT,but failed.Can you help me fix the DSDT about X3100 ? Thank you! http://www.mediafire...tkkktfwaugmzbaa

Here, I added the fix to your dsdt. See if it works ok.

mnfesq, please can you try to test native SpeedStep from the Legacy injector for Lion, attached:

1) Install in it /S/L/E.
2) Just change MacBook4,1 to MacBook4,2 (fake model) in smbios.plist
3) At same time you can revert back to vanilla MacBook4_1.plist, by deleting or comment out the five (5) lines for CPUPLimit = 0x0 inside:
/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources
4) Repair permissions & rebuilt cache, and finally restart the system.

Notes:
- This injector is recommended for Penryn CPUs, because C-States (CStateDict) information is different compared with MacBook3_1.plist (Merom).
- For Merom CPUs (using a fake MacBook3,2 profile) I can make another simple speedstep injector... please let me know.
- PLEASE, to understand what I did, use TextMate.app (attached too) to see the commented parts of the Info.plist inside the Legacy_speedstep injector.kext related to exclude all X3100 management references, which was discussed in this thread. Good Luck.

And Please set the profile (smbios.plist) to the fake model = MacBook3,2 (and download complementary files HERE).

- The proper FrameBuffer: AppleIntelGMAX3100FB.kext_Leopard_1058.zip (to avoid the "GPU parser error...")

- Please, add this code to your DSDT for to work with X3100FB.kext from Leopard 10.5.8:

Sure, I'll give it a shot. It would be great to get a true solution to this problem. However, I have the T7100 Core2Duo, which is a Merom processor. So, if you don't mind making one of those for me, I'll test it out and post the results. Thanks.

[mnfesq]

OK, I have things up and running. No problems rebooting after installation. Let me confirm I did what you instructed. I took my existing smbios.plist and changed the SMProductname from Macbook4,1 to Macbook3,2. I installed the Legacy_Speedstep_MacBook32_107.kext to S/L/E. If that's all I needed to do, let me know. In the meantime, I will use this setup and see if it avoids freezes/kps in usage I have known to cause them. Thanks.

EDIT - I wasted no time trying out something that had caused a freeze for me on several prior occasions. I ran a video in VLC while running another video in the Flash plug-in for Firefox. It froze as usual.

[mnfesq]

Today, using Firefox, sometimes streaming video to VLC and sometimes just downloading, I had 3 freezes in about one hour. The use of the Legacy Speedstep Injector has not provided any better performance than any other method I have tried. I did, however, notice a bit better performance with the 10.5.8 FB kext compared to the FB Lion kext.

try macbook5,1 or 5,2 .. i didnt see lion including gpu power controls with anything under 5,x

i wonder if theres a way to use the intel x3100 bios rom like nvidias and ati.

Thanks! I tried,and dark screen.Maybe I need add EDID of my LCD.

[juanerson]

You need is to take out the device (CRT) from your dsdt. And, just the basic X3100 injection. Please, try this:

If Juanerson's doesn't work either, let us know. I saw some errors in your DSDT that I could try to fix if it is needed (DTGP Method had minor errors and GFX0 should be inside the PEGP device.)

The results by using the Legacy SpeedStep injector (MacBook4,2 fake profile = smbios.plist):

I used your Legacy_SpeedStep_MacBook32_107.kext.zip for my merom C2D T7250,but he seems to not load, because in ioreg I do not see it. In smbios i changed model to mb3.2. that may be incorrect?

[juanerson]

It was installed in /S/L/E ? and just for record, did you repaired permissions and rebuild caché after install the injector?

yes and yes

I just want to report that I have not had a problem with video freeze or KP's for several days. Last week, I decided to stop testing 10.7.3 and did a fresh install of 10.7 with update to 10.7.2. I then used the smbios for MacBook 5,2 and installed the new IntelCPUMonitor.kext for FakeSMC. I also put FakeSMC and all of its monitor kexts in S/L/E instead of E/E. That's all I did to produce the better working condition. I observed a huge difference with the new IntelCPUMonitor. It made fixes for my Merom CPU and now the speedstepping works better than ever. It used to be that I had no more than 3 working P-States. Now, speedstepping works at frequency intervals of 200 MHz from 600 MHz to my maximum of 1800 MHz. I am thinking that the video freezes may be due to inaccurate CPU data which cannot be processed properly by the video kexts.

mnfesq,

Can you please upload your IntelCPUMonitor.kext and FakeSMC.kext I think I am having different versions.

mnfesq,

Can you please upload your IntelCPUMonitor.kext and FakeSMC.kext I think I am having different versions.

Here's my FakeSMC and monitor kexts. I use the ACPI Monitor, IntelCPUMonitor and X3100 GPU monitor.
