Guru3D have new AMD overclockers tool - umh well a calculator piece of code so to say...

Christopher Zinke has written a program that will help you to answer several questions you always might have had:

How big is the power dissipation of my overclocked CPU?
How high can I clock my super fast DDRAM memory?
How do I convert "CFM" to m³/hour? (or the other way round)
How do I convert MHz to that AMD rating? (or the other way round) You can grab the file from the Generic Utilities section of Guru3d.

No need to worry: The file does not change anything on your PC.
