BIOS Features

The P5ND2-SLI motherboard’s BIOS is a 4 MB ROM using a Pheonix-Award software package.  Asus must be having a lot of success with this BIOS as they seem to have adopted it pretty widely now.

The opening screen to the BIOS — nothing major being reported here; just the facts ma’am.

The CPU configuration menu here is going to give us some of our basic overclocking options.  The first setting here claims to unlock the processor multiplier, though I had no luck with in our retail processors.  The other options allow you to enable or disable the Intel CPU features such as the C1E thermal technology and the Execute Disable Bit.  HyperThreading remains a staple feature as well.

Our memory timing configuration allows us to set the timing options for DDR2 memory.  Here you see our settings as they were set during our benchmarks, a feat made possible by Corsair lastest 5400UL DDR2 modules (btw, you can win yourself some Corsair memory in our contest!).

Here lies the gamut of options for enabling and disabling all the many features Asus has included on the P5ND2-SLI.

This option allows you to disable the warning sound and light that occur if you have two graphics cards installed without the additional molex power connector attached.

The “JumperFree” menu is where the majorty of our overclocking options will come into play.  This first screen allows you to set an OC profile, including the options of Asus’ own AI Overclock and AI NOS.  We still tend to lean in the direction of the manual settings for anyone that wants to get into overclocking at all.

The PCI Express frequency can be bumped up to 150 MHz if you’d like.

These options allow you to either set the CPU bus speed, the memory bus speed, or both.  The middle setting there is what allows you the most tweaking options.

The Asus P5ND2-SLI board supports FSB up to 1600 MHz with our 3.73 GHz processor installed!  This is a bit outside the realm of the current processor technology, but its nice to have extra head room for the extreme overclockers in any case.

You also have the option of manually setting the memory speed of the DDR2 DIMMs.  You can take them all the way up to 1200 MHz if you think your modules and timing options can handle it.
