The BIOS is a more cleaner, standard issue higher-end Asus BIOS with a numerous options for voltage, front-side bus, and multiplier adjustments depending your need for performance gains, power savings, and overclocking. There is a bit of a change as most options now must be keyed in and there is no drop down except for memory speeds which might not be the best if you don't know your limits but the BIOS also provides information for the default and normal voltage ranges and let's you know when it is working outside of those ranges.

Overclocking was a success as increasing the voltages on our E6420 allowed us to obtain a 3.56GHz overclock or more than 1.5Ghz over the standard E6420. This however was still 100MHz short of what our Asus Striker II 780i which might be blamed on Intel's chipset inability to unlock memory speeds from the front-side bus

Dropping down the CPU multiplier and pushing only the front-side bus resulted in a 1.88GHz fsb overclock.
