Hi,

How can I know the max CPU multiplier while using intel turbo boost?
I had checked this web site "http://www.intel.com/support/tw/processors/sb/cs-029908.htm" .
But if there is a CPU spec. for each one the max multiplier should be while useing turbo boost?

Or it is just all the same? One core should be added 4 bin etc. ?

Anyone can kindly tell me about this? Thanks.

My test results as below:(I don't know if they are correct or not?!)

Xeon E5640 2.67GHz
One core--->Max multiplier 22
Four cores--->Max multiplier 21
Disable turbo boost---> Max multiplier 20

Core i5 670 3.46GHz
One core--->Max multiplier 28
Two cores--->Max multiplier 27
Disable turbo boost---> Max multiplier 26

Download CPU-Z, it will tell you everything about what your processor is currently running at.
