What signifies 'S'?

[SG nws]

I would like to increase the RAM in my laptop and I'm
wondering whether there is any significant difference
between PC2-6400 and PC2-6400S.
What does that 'S' signify?

AIUI S is for SODIMM so the 'S' variant is about half the size of a DIMM
and used in laptops.

www.mrmemory.co.uk and type '6400' into the search box. Or search for
your laptop's model.

(aside: remarkable that a professional website doesn't easily let you
create a link to a search result)

If that were the case, all SODIMMs would be suffixed by 'S',
and it aint so. No, I suspect it's something to do with the
chips on board.
I doubt that it's siginificant but, all the same, I'd like to know.

Let me be clearer, sorry. It's an abbreviation. Rarely used.

6400S = 6400 SO-DIMM

6400 = 6400 DIMM

That's one reason why the MrMemory site doesn't use the 'S': they spell
out SO-DIMM in full. SO-DIMM and DIMM are not interchangeable; they are
physically different although they have the same bandwidth. "Small
Outline Dual In-line Memory Module" or just the suffix S for Small.

It's best to use your desktop motherboard or laptop model number on one
of the memory vendors' websites than try and work out for yourself from
bandwidth numbers which is the right package to buy. You will also
probably find other compatible stuff and have comeback if it doesn't work.

So Tim, you're saying that, for instance:
"PC2-6400S PC2-6400 DDR2-800 800Mhz 200-PIN SODIMM"
is - at least - 2x tautologous! :-)

Looks like a line pasted from a spreadsheet, but ignoring the boundaries
and labels. How helpful. :-)

PC2-6400S | PC2-6400 | DDR2-800 | 800Mz | 200-PIN | SO-DIMM

I don't know but if you go to Crucial and enter details of you laptop they
will recommend the correct upgrade.

I endorse your recommendation, Stuart. I've bought from
them several times when upgrading old machines and have
never been less than satisfied.
