Default Re: i7 - Clock Speeds reporting wrong with OC?

CPUID is a fixed stamp Intel puts on every processor, it's a command that makes the CPU reveal it's STOCK, sold as model number and stock sold as clock speed. This is a FIXED function ID code, it never changes regardless of what you manually set the clocks to.

Sensor reads are what programs like CPUz and other programs that actually query the sensor, not the CPUs fixed function ID code. Some programs read sensors, others read CPUID. CPUID code is NOT to be confused with the program by the same name, that program does BOTH, reads the CPUID, then reads the sensor to confirm the CPUID.

Windows failure to read proper bus speeds is the cause for the clocks to be wrong at the end. Windows has always had that problem, something to do with CPUID itself causing the bug and it never being fixed.
