I got emailed HP about asking them if i was able to OC their system with the included BIOS and this is the reponse i got

Dear customer:

"Overclocking is a term used to describe the practice of running computer components above the specification set by the manufacturer. Many industry leaders including Intel and HP do not support or condone the
act of overclocking. HP does extensive testing on our systems to determine at which clock speed each part will operate consistently and reliably. Overclocking your Pavilion system may cause damage to the processor, memory and/or the system the processor is installed in. It
will also greatly decrease the life expectancy of the overclocked chip."

have any of you decreased the life of your chip by o/cing it?

HP is 100% correct in there e-mail.. running any component at higher levels then it was designed for will always increase the heat that the component produces.

Overclocking your Pavilion system may cause damage to the processor, memory and/or the system the processor is installed in. It
will also greatly decrease the life expectancy of the overclocked chip

since you would be running stock cooling, your proccessor would be running at an unhealthy tempature.. decreasing the life expectency of your system.

lmao, as if you could overclock an HP anyway..

The only thing that causes life depletion in a overclocked chip is increased core voltage, which does indeed decrease the life of the chip quite drastically, for pentium 4's (over 1.6v can and does cause SNDS). Athlons tolerate increased voltage quite well.

I killed my old 1.6A by running at 1.650 vcore and 2475MHz for 4 months.

i have an OCed intel celeron 300 that is running at 450 MHz with a voltage mod. running strong since the day it was put together. and that thing used to run 24 hours a day. then there was the AMD K-6 350 OCed to 400 MHz but it exploded from bad power supply. so in the end they last. but i havent tried to OC my new rigs yet.
