The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Overclocking new i7 965 EE cpu

Asked by Gssc1414 in Computer CPU Processors

Tags: i7 965 CPU, Overclocking

I am attempting to overclock a new CAD workstation that I built for work. I am new to overclocking, but am wanting to get the most out of this system (safely). I have read a lot of stuff online about how this core can reach 4.2 Ghz and all that jazz, but when attempting to OC with the settings they had, I had some system unstability. I am not looking to get the highest clock speed, just enhance the workstation to run faster (but staying reasonable). I guess my first question is the FSB speeds. In BIOS it is displayed at 133 Mhz (which I know, is stock for this core), but My memory modules are Corsair DDR3 - 1600 Mhz - a FSB of 200 mhz. Originally I bumped that up to 200 and backed to CPU multiplyer down to 18 (using a Core CPU voltage of 1.25v - well below the 1.7 that i have seen people running these cores at). I was then running at 3.8 Ghz - but reached some nasty temps (about 70C) when running a stress test. Also worth noting that I am using an Aftermarket Cooler with artic silver. Also, at stock settings the CPU temp is about 45 C (idle) - seems a bit high to me, but I have heard this core runs a little hot.

What is the best way to safely OC this core (I know OCing always induces a certian threat to burning up your core - I say safely in a relative fashion). Should I only slightly increase the FSB,  to like 135 Mhz - and then add to the multiplyer to get my speed up? Any suggestions?
