Is there a noticeable difference between PC2 5200 and 5300?
I have now both installed, 1 MB each of DDR PC2 5300 and 2X 512MB of DDR PC
5200.

Two things to know about RAM:
1- When mixing RAM of different speeds, all RAM operates at the lowest
speed.
2- You should only use RAM that has been specified for your computer.
The major RAM vendors (e.g., Crucial) have RAM selectors that easily
guide you to the correct RAM for your particular make and model of computer.

You won't unless you put them in the two banks wrong. You need the two 512s
in bank 0, and the 1 gigs in bank 1. The id is written on the MoBo.

Why confuse people? Explain yourself. Does higher speed memory slow down
when installed with lower speed RAM?

No this isn't correct. These RAM "speeds" are not really speeds at
all, but speed ratings--the speeds they have been tested to reliably
work at.
The actual speed the RAM runs at is the speed the motherboard is set
to run it at. For safety, that *should be* the lowest of the speeds,
but isn't necessarily. If it's a higher speed, you are overclocking at
least some of the RAM, and are at risk of failure, with consequent
risk to your data.
2- You should only use RAM that has been specified for your computer.
The major RAM vendors (e.g., Crucial) have RAM selectors that easily
guide you to the correct RAM for your particular make and model of computer.
I agree completely with that.

Ken is correct, of course, and he provided more detail than I thought
was needed.
RAM (and CPUs) do not run at a set speed. Indeed, they are capable of
running over a wide range of speeds. However, they do have a 'rated'
speed - this is speed at which the manufacturer can predict the results.
RAM and CPUs can successfully be run at higher or lower than rated
speed, if you know what you're doing and you have a sense of adventure.
Absent over- and under-clocking, when different speed RAM modules are
used, then all of the RAM should clock to the speed of the slowest
module. In reality, mixing RAM speeds can cause your system to be
unstable (but not necessarily so). For that reason, it's always best to
use RAM of the same speed.

Thanks, Leonard. The reason I thought clarification was needed because
the oft-seen statement that "When mixing RAM of different speeds, all
RAM operates at the lowest speed" erroneously implies that if you have
RAM running at a particular speed and you add slower RAM to it, it
will therefore all be run at the slower speed. In fact, unless you
change a setting, it will be all be run at the *higher* speed, and
with the attendant risk of the overclocked slower RAM failing.

"In fact, unless you change a setting, it will be all be run at the

An internet search for 'mixing RAM speed' should make it clear for
anyone reading.

It doesn't clear anything, it muddles things up even more! All the RAM
manufacturers and all the RAM sellers always say that if you mix RAM of
different speed that (even if the FSB can handle the higher speed) it
will run at the speed of the slowest module.

I will say this for the last time:
When you mix RAM of different speeds, all the RAM operates at the speed
of the slowest module, unless your computer crashes altogether. For
further information, conduct a web search with the search engine of your
choice using the following search term: mix RAM speed

Both ridiculous comments. Any memory installed in a computer will run at the

Very simply, that you appear to believe that to be true.
