Intel DP55KG offers some overclocking options. The main options we could see with the initial BIOS release (86A.3456) were:

• CPU base clock: can be adjusted from 133 MHz to 240 MHz in 1 MHz increments.
• PCI Express clock: can be adjusted from 100 MHz to 110 MHz in 1 MHz increments.
• CPU voltage: From 1.0 V to 2.3 V in 0.0125 V increments.
• Memory voltage: From 1.3 V to 2 V in 0.01 V increments.
• Memory controller voltage: From 1.1 V to 1.8 V in 0.01 V increments.
• Chipset (PCH) voltage: From 1.03 V to 1.5 V in 0.01 V increments.

Memory timings can also be tweaked. Intel DP55KG also offers detailed configuration for the CPU Turbo Boost mode.
