EVGA H55 has several overclocking options on its setup. The main overclocking features found on this motherboard are:

• Adjustment of the CPU base clock from 100 MHz to 300 MHz in 1 MHz steps.
• Adjustment of the PCI Express base clock from 80 MHz to 200 MHz in 1 MHz steps.
• Adjustment of the “bootup” CPU voltage from -400 mV to +60 mV in 10 mV steps (on top of the current CPU voltage).
• Adjustment of the “eventual” CPU voltage from -400 mV to +60 mV in 10 mV steps (on top of the current CPU voltage).
• Adjustment of the “bootup” CPU VTT voltage from 1.050 V to 2.000 V in 0.025 V steps.
• Adjustment of the “eventual” CPU VTT voltage from 1.050 V to 2.000 V in 0.025 V steps.
• Adjustment of the memory voltage from 1.20 V to 2.13 V in 0.01 V steps.
• Adjustment of the chipset (PCH) voltage from 1.050 V to 2.000 V in 0.025 V steps.
• Adjustment of the CPU integrated video processor (IGP) voltage from + 0 mV to +150 mV in 0.25 mV steps (on top of the current IGP voltage).
• Adjustment of the CPU clock generator (PLL) voltage from 1.050 V to 2.000 V in 0.025 V steps.
• Adjustment of the memory data reference voltage from +0 mV to +150 mV in 0.25 mV steps (on top of the current voltage).
