ASRock H55DE3 provides a simple overclocking setting on its setup called “Turbo 50,” which promises 50% performance increase on 3DMark06 (this performance increase won’t be that high on other programs). This option can only be enabled if you install a CPU with integrated video controller and use the integrated video controller.

This motherboard brings several overclocking options:

• Adjustment of the CPU base clock from 100 MHz to 300 MHz in 1 MHz steps.
• Adjustment of the PCI Express base clock from 50 MHz to 150 MHz in 1 MHz steps.
• Adjustment of the CPU voltage from 0.84375 V to 1.60000 V in 0.00625 V steps.
• Adjustment of the CPU VTT voltage from 1.11 V to 1.55 V in 0.06 V steps.
• Adjustment of the CPU integrated video processor (GFX) voltage from +0 mV to +300 mV in 100 mV steps (on top of the default voltage).
• Adjustment of the CPU clock generator (PLL) voltage from 1.81 V to 2.18 V.
• Adjustment of the memory voltage from 1.30 V to 2.05 V in 0.05 V steps.
• Adjustment of the chipset (PCH) voltage from 1.05 V to 1.25 V in 0.10 V steps.

Below you can see some screenshots from the motherboard setup.
