BIOS Features
The Asus P5E3 Deluxe motherboard BIOS is one that overclockers are going to love and has the power to get just about any kind of tweaking done right.

Setting the Asus “Ai” overclocking setting to manual opens up all the overclocking goodness that you want access to.

The CPU ratio adjustment is manually inputted up to 31x in this case!  I don’t know who they are kidding but you need a really low FSB to get that up and running.

Here you can adjust the ratio between the FSB and the north bridge but this is NOT used to adjust the memory frequency ratio.

The front-side bus on the Intel CPUs can be moved up to 800 MHz, or 3200 MHz quad-pumped.

The PCI Express frequency of the two full x16 lane PCIe slots can be increased from 100 MHz to 150 MHz.

Here is where the memory speed adjustments are made — you can set the memory up to 1333 MHz when at the default FSB speeds.  As a nice touch, when you are overclocking the FSB, these speeds (that are actually changing a FSB/memory ratio) will change to reflect the actual resulting memory frequency.

Command rate on the memory modules can be adjusted to 1T or 2T here.

Here is the WIDE array of memory timings that can be adjusted in the Asus P5E3 Deluxe BIOS.  While I really do like the way that some previous boards have displayed the “current” setting along with the adjustments possible, the BIOS here does include the SPD information listed as “Pri Information” and “Sec. Information” which is something.

The “Ai Clock Twister” sounds more exciting that it really is – the options are detailed on the right side of this shot.

Clock skew settings are available for those with more memory experience than me…

I just LOVE these completely ambiguous BIOS settings — apparently the “Transaction Booster” will “affect performance directly.”  Nice.

The voltages on the Asus P5E3 Deluxe motherboard are very good, but the input method is key them in directly.  A change from what we are used to but very nice as you no longer have to scroll through TONS of options to set your voltages.  Here you can see the max for the CPU voltage is 1.7v.

The CPU PLL voltage is maxed out at 2.78v.
