In regards to my CPU, most article (include the Wiki) told me that I must use "FSB", but I don't have such a value (see below) so I have some question about CPU:
Intel(R) Core(TM) i5-4670 CPU @ 3.40GHz
What does the "3.40GHz" mean?
Clocks (Core #0)
Core Speed : 801.4MHz <-1.4MHz more than Intel published
Multiplier : x36.0 <-changing continuous, but most cases lower than 40
Bus Speed : (empty)
Rated FSB (<-graytext) : (empty)
How to understanding these values? Can I do something like 801.4*36/1000? I notice that windows8 taskmgr shown my CPU speed is "0.80GHz"
But some time later, it suddenly jump to 1.60GHz and back to 0.8 in few seconds Is my computer run in power saving mode? Or my CPU support something like turbo mode?
PS: CPU temperature always low enough (About 40°~60°).
