The steps to reproduce the problem: Use any build of Chameleon 2.0 and 2.1. The version of the software and your operating system: Lion 10.7.1 Any information that can help the developers to solve the issue: When using Chameleon as bootloader my QPI speed is detected as 5.8 GT/s when it should be 4.8 GT/s. I'm attaching my DSDT.aml My CPU is a Core i5 760 overclocked at 3.41GHz. I'm sure my QPI is 4.8GT/s. Everything else in my system is detected properly (memory speeds and manufacturer). Here are my other details: eVGA P55 Micro SLI Corsair 2GB DDR3 1600 x2 Geforce GTS 450 1024MB I have almost everything set through DSDT. Using Chameleon 2.1 RC r1493

EDIT: solved adding Smbussped=4800 to my smbios.plist. Although I think it should be detected by the bootloader itself. Please close this issue or find out how it could detect properly the BUS speed. I forgot, I have an iMac 11,3 SMbios.

When you over clock the FSB on a P55 system the QPI is also over clocked. On Gigabyte P55 motherboards the BIOS shows the operating QPI speed.
