I just purchased this system after saving and collecting Christmas money. I opted out of buying a heatsink, monitor, and OS. Good news is the 64-bit Windows 7 Beta is out, and it is working very well. I was having problems on XP 32-bit, but that's off-topic. I'd like to OC using the stock Intel Heatsink and my goal is to achieve 3.0 ghz. I have some questions: What is HPET? I set it to 64-bit since I run on a 64-bit system but are they even related? Is my goal even reasonable? What voltage ballpark should I be looking at? What should I know about my cpu/memory divider?

What I've Done:
I've reduced the Vcore from 1.325V to 1.25V and it has been stable running Prime95 so far. I would like to try to lower the voltage further to determine a baseline to overclock off of, but I don't know how severe the repercussions would be if I lowered them too much. I have lowered my maximum core temps under full load on each core by 4-4-6-6 degrees C on each core respectively. Currently running at 56-56-50-51 degrees under full load. I've set the PCI clock sync to 100 MHz, but are there any other options I should take off of auto and set to a fixed quantity? Thanks.

Hmm, 3Ghz may not be doable with acceptable temps on a stock cooler, but you can for sure run it and see how they are.

HPET is High Precision Event Timer and yes you have set it correct for x64 >>>
High Precision Event Timer - Wikipedia, the free encyclopedia

There would not be any sever repercussions from lower your Vcore until you hit a failure point. The system would just start failing tests or fail to boot is all

Well you should put performance enhance on standard, set your ram voltage, and then set MCH Voltage to 1.2-1.3 (1.22-1.26 likely good) and then overclock from there. And of course disable C1E and EIST

Please do set your own Vtt (Termination), PLL, and Vcore. DO NOT USE Auto for those, especially Vtt and PLL as Auto way overvolts them

If you need some help, let us know we can help for sure! If you do run into issues and feel you cannot solve them please do post your exact settings used here and we will post back some advised changes >>>>

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours
