System: CPU voltage: 1.525 Note: The 920 is locked. It's overclocked by increasing the QPI frequency from 133.2 MHz to 186 MHz. That brings it to 186MHz x 20 = 3720 MHz. However, because of "Turbo Mode" 2 speed bins are added automatically to the default multiplier of x20. That brings the CPU frequency to 186 MHz x 22 = 4092 MHz. The system was running for 1 hour Prime 95 at this frequency.
