I have a memory bus speed question.

I have a HP Pavilion 6830kr. It has a FSB that runs at 66mhz. The memory modules are PC100s. This gives it a memory speed of 100mhz.
My question is does the memory travel to the processor at 66 or 100mhz???? Why this is bothering me I don't know.
 
AFAIK If the FSB is running at 66mhz,
then your memory is also being accessed at 66mhz.
The PC100 rating only means they are capable of 100mhz speed,
the motherboard/chipset set the actual speed.
You could probably install a PC133 SDRAM in
your system, but it would still only run at the speed set by the motherboard.
(66mhz in your case)

There are exceptions to this,
some motherboards have a setting in the BIOS to run the memory
at +33/-33 of the FSB.

I tried looking up your system at HP:
HP site
but it didn't tell me a whole lot.
🙁
 
PCxxx number isn't the speed that the ram runs at, it's the maximum speed the memory is guarenteed to run at.

Just because your car has a 108MPH speed limiter doesn't mean you are always doing 108MPH.
