Hello,On my E6500 CPU (marketing freq 2.933) the "real frequency" is listed by PC Wizard as 1597.... The chip runs alternately betw 2.933 and the 1597. Why?

That is an energy efficiency operation called Speedstep that lowers your CPU's multiplier while idle, and is completely normal.

You can turn it off in the BIOS if you wish, but it doesn't effect performance.
