@shakall, I'm pretty sure you can use the E757, and I bet if you don't use any bios version newer than S71H, you can use the folder these guys are passing around.
@everyone, I've gotten maybe a little closer to getting speedstep on my E767. In my ioreg I have no CPUPLimit, nor do I have CStateInfo. I made a legacy kext based on MacPro5,1, renamed to PowerMac3,4 just for fun, and changed my smbios.plist to PowerMac3,4. I still don't have either of those in my ioreg, but now I get:
Code:
11/24/10 4:41:33 PM kernel ACPI_SMC_PlatformPlugin::gatherCStateOverrides - failed to set c-state demotion data: -1
I built it in a PowerMac3,4 case if anyone was wondering.
I also updated to bios 77, and now I only get one ssdt.aml instead of two.
Maybe when people start trying to run 32nm 6 core chips on their EVGA boards more people will be trying to get this working than me.
