DFI Infinity NF650I Ultra Motherboard - BIOS and Overclocking

DFI has used the Award BIOS system that has proven to be a winner when it comes to simplicity to use and effectiveness.


Users who have used Award BIOS will find no surprises here; it is a straight forward setup. To overclock the system you need to open up the Genie BIOS settings menu, where there are three sub menus where you can overclock your system.





FSB (QDR) MHz: 400MHz to 2500MHz in 1MHz Increments


Mem (DDR) MHz: 400MHz to 1400MHz in 1MHz Increments


PCI-e Bus Slot 1: 100MHz to 131MHz in 1MHz Increments


SPP MCP Ref Clock: 200MHz to 500MHz in various Increments




CPU VID Special Add: 100% to 156.39% in various Increments


DRAM Voltage Control: 1.8v to 3.0v in 0.02v Increments


NB Core Voltage: 1.3v to 1.45v in 0.025v Increments


SB Core Voltage: 1.5v to 1.85v in 0.05v Increments


SB Dual Voltage: 1.5v to 1.8v in 0.1v Increments


HT Core Voltage: 1.2v to 1.6v in various Increments





Despite being a value based board on the nForce 650i Ultra chipset, we managed a respectable 438MHz FSB.


We had to push all the voltages to their maximums apart from the CPU voltage, we only hit 1.45v. It is not the 500MHz+ FSB we see on high-end motherboards but it's not too bad considering the price tag.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time testing the motherboard. Due to time constraints we don't have enough time to tweak the motherboard to the maximum and find the highest possible FSB as this could take days to properly find. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking or as new BIOS updates are released or "burn in" time might come into play if you believe in that.
