Programmatically set max CPU multiplier on Sandy Bridge i7 2700K

  • How do I programmatically set the CPU voltage and maximum CPU multiplier for Sandy Bridge processors?  Similar to the functionality provided by motherboard software such a ASUS TurboV.
    I'm fine with writing kernel-mode drivers, and you can post example code in pretty much any programming language (ASM / C / C++ / Pascal preferred though).

  • Also, just out of curiosity, does anyone have an idea of how would I monitor the temperatures (particularly, individual core temperatures)?
  • Can the individual multipliers for each core be queried, or do they have to be measured via BCLK and RDTSC/thrash/RDTSC?
