Absolutely correct. This is known as virtual memory. Even if you are NOT
running an application, but it is in memory, and you wish to run some other
program, what is in memory has to be written on the disk (saved) and the new
program loaded. This is a very good reason to keep Startup as small as
possible. I.E. Don't load it till you need it.

Additional RAM might help some, but how just much it'll help mostly
depends upon the specific applications you use, and how they use/release
memory. I'm afraid there's no hard and fast answer.

I
already went to crucial's site as I mentioned before.

I know, but I wasn't sure if you checked for maximum capacity, as well
as the type of RAM needed, so I wanted to clear up this point, before
you spent money on soemthing you couldn't use.

also, what do
you mean by huge "bottle-neck"...

Sorry. It's a term (alluding to a bottle's narrowed opening) used to
identify a constriction in a process that slows everything down, no
manner how fast the rest of the process might be. Let me try an
imperfect analogy:

Think of a multi-lane expressway that suddenly comes to a toll station
with only one booth manned and/or operating. No matter how fast the
traffic was flowing before it got there, and no matter how fast the
traffic might once again flow once past, that single toll booth is
creating a "bottle-neck," bringing the traffic to a near-stop as it
processes one vehicle at a time.

Your P-III CPU may act in a similar fashion as your increased RAM
provides it with more data traffic at any given time; it can only
process the data so faster, regardlees of how much more data is coming
its way.

Mooky, I'm going to disagree with Bruce here. If additional RAM does
anything for you, it will be because it reduces or eliminates paging
to the hard drive. Reading and writing to the hard drive are physical
mechanical events, and always much slower than the electronic
manipulation of data that occurs in the CPU or in RAM. For that
reason, reducing of paging will almost always provide a speed
increase, and usually a substantial one. It's the hard drive that's
the bottleneck here, not the CPU, which, even if old and slow, is
still many times faster than the drive.

thanks for the info...I thought that it might reduce the paging size
and provide a speed increase. the Memory is about the only upgrade to
my PC I can do...I had to upgrade the hard drive a few months ago to
replace my old croaking one...even with all the stuff I have on my
drive I still have 102 gigs free...and I also put in a new dvd burner
as well...also, I said I'd have a stick of 512 for backup which did
mean a replacemet...that was only if the slot is bad and I just store
the 2nd stick until needed. Thanks again...helped me out alot.
