UnOfficial Asus Rampage II Extreme Thread

[jasonelmore]

Alright here are the settings to reach 4.0 Ghz with a Core i7 920. This will allow you to get 4.0 Ghz on all cores and 4.2 Ghz in turbo mode. This will really help your Super PI Scores. Note: Try my CPU voltage first. If it still blue screens that is a sign that you need more voltage. If it does'nt blue screen then you can try to back it off a little at a time. Do this in .05 increments. For Example 1.43 then 1.38 then 1.33. The same goes when increasing your Vcore Voltage. Print this post out and follow the settings EXACTLY!

ON YOUR RAM VOLTAGE SET IT TO 1.66v

Like i said, If you Blue screen with these settings that means you need more CPU Voltage. Only increase it at .05v at a time. So i have you starting out at 1.43. If this does'nt work, then try 1.48. You should'nt have to go over 1.5 to hit 4Ghz. Actually you will probably be able to get a lower voltage than i have listed above. I have found out that i have a power hungary chip. Also you need some good cooling. This is'nt recommended at all on the stock cooler so DONT DO IT!

The most I recommend doing on the stock Cooler is 3.2 Ghz. And i'd just use the CPU level up Feature for that one.

The goal here is to get you to windows. Then you can tweak your memory and all that good stuff.

Hope that helps.. if you have any questions just PM me. And if you have a better overclock POST IT!!!!!
