    15 There are generally 5 VID pins. Recent motherboards may use 6 pins. 
    16 The VID codes are defined by Intel in documents titled 
    17 "VRM X.X DC-DC Converter Design Guidelines". 
     15There are between 4 and 8 VID pins (the more recent the CPU, the more 
     16numerous the VID pins.) The VID codes are defined by Intel in documents 
     17titled "VRM X.X DC-DC Converter Design Guidelines".
