I have a P5W DH Deluxe rev 1.02G board and recently acquired an E8600 cpu. After flashing to 2801 and installing the chip I noticed i was also unable to set lower voltage values in the bios.

Then I downloaded and installed the latest Asus AI Overclock utility. To my surprise I was able to set lower voltage values through the utility than through the bios. After re-booting the system posted 4ghz as if it was taking the new lower voltage. I went into the bios and notice the voltage value was 1.4 (not the value I set) but it was highlighted differently. My system was not stable but I have yet to do any further tweaking.

I would think the bios should at least report the values set by their overclocking utility. Is the utility a backdoor to setting up the bios on these older rev boards? Is it advisable to continue down this road?
