Maximum CPU voltage goes up to 2.1V, HTT voltage to 1.5V, chipset to 1.96V and memory to a very sweet 4V. The chipset and memory voltage options increase in 0.03-0.04V which gives users a lot of options.

	experts tip: not all memory works better with higher voltages
	as a general rule of thumb, when voltage is raised the overclockability of most components is increased. depending on the type of memory used in an overclocker system however, this rule doesn't necessarily apply. Winbond BH6/5/UTT based memory tends to increase in performance as the voltage goes higher (additional cooling may be required) however Samsung TCC5/D DRAM and Hynix D43 based modules definitely do not react well to the same high memory voltage settings. Raising the voltages past 2.9V is more often then not a bad ideal with the latter types, so it pays to know the specifics of the DRAM on the memory installed in your computer before going past a DRAM voltage setting of 2.9V in your own overclocking adventure.

The DFI LANPartyUT NF4 SLI-DR Expert allows users to switch SLI on and off within the BIOS. Something to remember when running SLI.

DFI CMOS Reloaded:

The CMOS Reloaded section is probably the most useful feature of the DFI BIOS. There are four blocks which allow users to save and load different BIOS settings.

The CMOS Reloaded feature is very useful for the tweaker; nothing is more frustrating than having to reset the BIOS only to forget what settings were being used. As you can see there is also the ability to write a brief description next to each "User defined setting bank" which is certainly helpful for separating stable settings from more experimental collections.
