Why is the BIOS unable to over-clock using the % increase feature in the Extreme Over-clock section of the Asus P5n32-E SLI PLUS MOBO? This refers to the AI-NOS feature. The PC freezes on boot to BIOS with a dark screen & beeps. I suspect the power supply of 550W (true as in Thermaltake) may be too under-powered. The RAM is suppose to be compatible & PC runs very good in the "Auto" BIOS setting (no over-clocked).

I've searched the ASUS Forum for this MOBO & soem other do have this same issue of no use of AI-NOS or over-clock % increase settings.
Advice given is to not use these features & manuall over-clock. I do not know how to over-clock sucessfully & would feel terrible to ruin my new PC by just trying (failing).
I don't fully appreciate recieiving advice to not over-clock; doesn't answer my question at all.
However, I can easily live with this PC not over-clocked;
just wanted to try the % feature without damaging my PC.
The ASUS % over-clock does work for others who know nothing about over-clocking manually, so that's the issue at hand.
Thank you for your interest/time on my behalf.
