OKay I did it. What is the difference between Bus Speed and Rated FSB?
My bus speed is showing at 200mhz and my Rated FSB is showing as
800mhz. Does that mean that my CPU is running at its full 800mhz? I
just dont' know the terms. Sorry. Also, under SPD, my memory setting
under Max Bandwidth is showing as PC3200 (200mhz), isn't it suppose to
be 400mhz? Really getting confused here. This mobo is frustrating me.

On an Intel processor, the clock is 200MHz. The bus is "quad pumped",
meaning the bus can pass four 64 bit words per clock cycle. We
multiply the two numbers together to get the term "FSB800" from
200x4.

DDR memory has a similar story to tell. The basic memory clock
is 200MHz. The memory interface passes two 64 bit words per clock
cycle. That is where the "Double Data Rate" terminology comes
from. We also call that DDR400, which is 200x2. At the double
data rate 400MHz transfer rate, since 64 bits or 8 bytes of data
are being passes, the bulk transfer rate is 3200MB/sec. That
is shortened to "PC3200" to refer to the memory transfer
rate. So a 200MHz clock passes DDR400 data, for a total bandwidth
of 3200MB/sec.

It is all sounding pretty normal. But to be sure, what kind of
motherboard, processor, and RAM is it ? My crystal ball is a
bit fuzzy...

Hi folks. I'm trying to find an app that can tell me what my current
RAM speed is (333mhz, 400mhz, 233mhz). I'm having issues with a new
board recognizing the RAM and CPU speed. I did manually configure it
but I wanted to be sure it is functioning correctly. Thanks.


CPU-Z. Will tell you current clock speed for each stick as well as
reading the SPD chip on the DIMM.
