FOXCONN uses the Award Phoenix BIOS with a few modifications. In the Systems Monitor section of the BIOS, the BIOS gives up to the minute readings of the voltage, fan speeds and temperatures of the system. The CPU FSB can be set from 100MHz to 500MHz in the System Clocks menu. Here you can also change the CPU multiplier from 4x to 13x in the case of the 5000+ we use for testing.

Voltage changes for the System can be changed from the System Voltage submenu. CPU voltage can be changed from 0.3750V to 1.8500V in 0.025V increments. Memory voltages can be set from 1.825V to 2.500V in 0.025V increments. HT CPU-nForce SPP voltage can be set from 1.210V to 1.400V in 0.025V increments. The HT nForce SPP-MCP voltage can be set from 1.325V to 1.500V in 0.025V increments. nForce SPP voltage can be set from 1.250V to 1.400V in 0.050V increments. nForce MCP voltage can be set from 1.525V to 1.700V in 0.025V increments. Auxiliary voltage can be set from 1.5V to 1.7V in 0.1V increments.

CPUZ overclocked


I was able to overclock the CPU using NVIDIA's nTune to only 8% over the standard FSB of 200MHz. At the same time, AGP/PCI Express frequency was overclocked by almost 50% and the GPU overclocked by 20% for the core and memory. Manually overclocking the CPU I was able to set the OC to 10% above standard without issue as to stability.
