MSI P55-GD85 Motherboard

Overclocking Options (Cont’d)

The main options we could see were:

• CPU base clock: can be adjusted from 100 MHz to 600 MHz in 1 MHz increments.
• PCI Express clock: can be adjusted from 90 MHz to 190 MHz in 1 MHz increments.
• CPU differential amplitude (“CPU amplitude control
  ”): 700 mV to 1 V in 100 mV increments.
• PCI Express amplitude control: 700 mV to 1 V in 100 mV increments.
• CPU voltage: From 0.9 V to 2.1 V in 0.006 V increments.
• CPU VTT voltage: From 0.451 V to 2.018 V in 0.006 V increments.
• Memory voltage: From 0.300 V to 2.400 V in 0.015 V increments.
• Chipset (PCH) voltage: From 1.000 V to 2.400 V in 0.05 V increments.
• Memory data reference voltage: From 0.450 V to 1.150 V in 0.025 V increments (for each memory module).

Memory timings can also be tweaked.
