Need Help Interpreting clock speeds

Can someone explain these various clocking's of my MOBO & CPU?
Or advise me where on the web I might find a lay-woman's'
view/interpretation of these things?

For example, I am trying Everest Home Edition which says:

CPU Clock                           2402.86 MHz
CPU Multiplier                     12.0x
CPU FSB                             200.24 MHz (original: 200 MHz)
Memory Bus                         200.24 MHz

Some questions I have (out of admitted ignorance) for example are:

Is the CPU FSB part of the CPU itself?
Is the Memory Bus part of the motherboard itself?
What would be the effect of my motherboard's RAM on these two speeds,
if any?
Does my RAM have a clock speed?  If so, how do I determine it?
My motherboard manual says its 'system bus' is 800MHz.  So how come
Everest reports 200MHz?
Are there other clock speeds I haven't mentioned?

I would appreciate any informative responses.

welcome to the pc world.

your pc has either an
Athlon 64 3700+ or Athlon64 3800+ CPU
DDR 400 memory
HT 800

These use HT(hyper transport) this means that the 800fsb number is
calculated as a muiltiple of the CPU FSB. The standard is 4x therefore 200 x
4=800.

Is the CPU FSB part of the CPU itself?
Sort of, lol. the fsb provides the "base" frequences for the other
components on your motherboard. The CPU speed is calculated by multiplying
this number by the cpu multiplier(12x 200=2400ghz). Manipulating these two
is essentially whats called "Overclocking" if you like your PC's warranty
don't do it.

Is the Memory Bus part of the motherboard itself?
No. the memory bus is part of the memory. It is the speed at which you
memory is running you have DDR400 memory(Double Data Rate 2x speed of memory
bus)

What would be the effect of my motherboard's RAM on these two speeds, if
any?
i don't quite understand this one, but if you increase you fsb it will also
increase the speed of the memory, eg. fsb 250, therefore memory =250(500
DDR). Your motherboard and ram are two seperate components.

Does my RAM have a clock speed?
Yes, its clock speed is the "memory speed" therefore 200mhz

My motherboard manual says its 'system bus' is 800MHz.  So how come Everest
reports 200MHz?
to repeat myself slightly, "These use HT(hyper transport) this means that
the 800fsb number is calculated as a muiltiple of the CPU FSB. The standard
is 4x therefore 200 x 4=800."

Are there other clock speeds I haven't mentioned?
Well beyond these four numbers all i can say is you got a pretty good pc,
anything that comes stock with a Athlon 3800+ or 3700+ must do the works,
lol

Enjoy ur pc
hope i was of help

Actually I have an AMD Athlon64 3400+.
DDR400 is right though.

I think so - and I appreciate both your comments and those of Chris.
It's still clear as mud though.

Maybe I can GOOGLE something like 'explain computer MHz' or something
like that.

Let ya know what I discover, if anything.

maybe you said
but you should have said

It helps if you've done physics

mhz means 1000's of cycles per second or 10^3 x s.
a cycle is essentially a processing unit in which a cpu does calculations.
therefore the more cycles the more calculations roughly. the number of
calculations is also based on the number of transistors on the chip the
average modern cpu has about 100 million+!(your cpu has 105.9 million!) Each
transistor works like a simple logic gate, its either open or closed,
therefore issuing digital commands (1's and 0's). So all these transistors
change every cycle, therefore the more cycles per second coupled with more
transistors, means more data can be processed, meaning a faster computer.
Thats how i understand it. Memory works slightly differently, how exactly
i'm not sure,

try this site

www.howstuffworks.com

fantastic for all these General knowledge questions

Thank you
