Built a PC for this OC on an air cooled system:

Mobo: ASUS P6X58D Premium
CPU: Intel Core i7-920 C @2.66GHz OC'd @3.6GHz
Cpu cooler: Zalman CNPS9900 LED fan
RAM: Corsair XMS DDR3 1600GHz 7-7-7-20 1.65v
HD: 3 Kingston SSD v in RAID 0 for OS
HD: 2 Hitachi 2.0TB HD for data
CASE: Antec 900 v2
Graphics: dual ATI RADEON 5870 xfire
PSU ANTEC 1000
Monitor: ACER 23" T230H touch screen monitor
OS: Quadruple boot to XP, Vista x64, W7 x64 RC1, W7 x64
Overclocked the i7-920 using the 3 step overclocking guide by Jeremiah Allen check it out at Overclockers forum.
This is an excerpt from the guide:
Prerequisites In an earlier version of this guide, I requested that you have some basic knowledge of your motherboards BIOS.  While I have not addressed every motherboard on the market, I have included details for the top enthusiast brands.  But as before, please do not be afraid to get into your BIOS and have a look around, if you are ever concerned that you may have changed a setting erroneously, you can always load defaults, and start over.  Most boards have a CMOS reset button on them now-a-days, if not check your user manual for the location of the CMOS reset jumper...please ensure you know the location before getting started.
This guide is independent of your cooling system.  Whether you are using the stock Intel cooler or if you're pushing to the extreme with phase change cooling, the basic steps remain the same.  One thing that is far too common are mistakes mounting your cooling system, specifically the application of the thermal interface material (TIM).  If you don't have much experience mounting cooling apparatus, please refer to this excellent guide from Arctic Silver.

Methodology Determining methods for finding a stable overclock are highly controversial, everyone has their own definition of a stable system, but when I refer to "stable" in this guide, I am referring to the stability of your selected "stability test."  So for a power user or gamer who wants a reliable system that won't ever crash due to an overclock pushed too far, you'd need to test with a program that will load all of the cores and threads applicable to your CPU, OCCT and IntelBurnTest are two popular choices.  OCCT uses the same algorithm as Prime95 but has a more friendly interface.  IntelBurnTest uses the Intel linpak binaries to stress the system and also has an easy to use interface.  In this guide I may use testing this is insufficient in your opinion.  It is only a guidline and if you feel more testing is necessary for your system, by all means feel free.
So with that in mind, we will attempt to isolate each portion of the system and overclock one step at a time.  This may seem time consuming at first glance, but rest assured this will potentially save you hours of troubleshooting and frustration. So go slow, and follow each step very carefully.

  • Where did you download the guide from, I checked the link in the description but no download or any of those pictures yo are showing are there?

  • @RonnieB5555 The pictures I show and everything else including the video were created by me and therefore you will not find them anywhere else. The link I posted is still valid I just checked it. There is nothing to download from there though, you can read Miahallen's guide which is the same I did and then I based this overclock on my interpretation of that guide.

  • Hello, I have the same motherboard on i7 975 3.33 extreme along with 3 2GB DDR3 2000 MHZ corsair Dominator with a corsair H80 liquid cooler. I am running the Intel Extreme Tuning Utility; i set the Bios settings in the AI Tweaker to third party so i can autotune but it only mess with the voltage settings it does not change the Host Clock Fequency. Is there an option that i need to turn on in bios? I dont want to mess with the bios settings if i dont have a guide for my particular situation.

  • I would not be overclocking memory, you barely get any increase

  • why IOH volt @ 1.1 if in your guide says 1.15 for those who got dual graphic cards?

  • @PUA687 Thanks for the reply I thought that those images you were showing came on a download from that link. The videos are really good and very detailed, I am going to use this to try and reach a stable 4ghz overclock.

  • Keep the videos coming man

  • @66lwmorgan Look up your type of RAM and it should list specs. If your RAM has heatspreaders it should be there.

  • You said your memory was 7-7-7-20, how do you find that? Great video George
