The Advanced Chipset section of the BIOS allows the user to change the HTT link multiplier and control the PCI Express bus frequency. The Overclocking features menu is where you set the voltages, multipliers, bus speeds and memory settings on the motherboard BIOS.

Athlon 64 CPUs are Multiplier unlocked. What this means is you can change the multiplier lower than the default multiplier to drive up the CPU speed. The CPU voltage range is from 0.00V+ to 0.25V in 0.025V increments. HTT link speeds are adjustable from 200-400MHz in 1MHz increments. The voltages to the Crossfire 3200 chip are modifiable from 1.22V to 1.5V. Memory voltage can be set to from 2.5V to 3.0V in 0.1V increments.

Overclocking of the motherboard was limited by the CPU we use for overclocking. It registered a speed of 2.52GHz, a 120MHz overclock, typical of motherboards we've tested with the 4000+ in our test system. The RD580 chipset is very overclockable as a rule and should provide a good experience to the high-end user.
