I configured my overclock through the BIOS, but when I was looking through the Intel Extreme Tuning Utility I saw a section I don't understand. There's a section called "Per-Core Overclocking Setting" with "Ratio Limits" for each core. All the values are set to 120x, except for Core 3 which is at 8x. At first I thought it was a core multiplier, but with a value of 120x it clearly isn't.
I don't remember seeing anything like this in the BIOS. What is it, and why is one core at 8x while all the others are at 120x?
