Good morning all,
I just bought a Dell Latitude 5440 as it has two RAM slots. One is
populated by a DDR4 16GB sodimm.
But I have a spare sodimm of this spec:

Will this fit and work in my new laptop?
No, it is a Latitude 13th gen 5440. According to Crucial UK, it can
take up to 64GB RAM either DDR4 or DDR5.
Will this fit and work in my new laptop?
is that the Latitude e5440 ?
Will this fit and work in my new laptop?
is that the Latitude e5440 ?
if it is, then the max memory for the machine is 16 GB according to Mr
Memory ...

Why are you wasting time with a 8GB stick then ?

It's not this machine, because the processor here takes DDR3 memory.

Also unlikely that 16 GB of RAM was being utilized in the past
- i.e. more RAM(extra 8 GB even if operating in dual channel mode due
the two stick combination) doesn't mean more RAM usage. Efficiency with
dual channel may be present, but measurable and experienced - maybe not.
The sweet spot for Windows 10 and 11 for most devices is 12 GB RAM,
though if gaming is involved, then 16-24 GB may see a noticeable(slight) improvement in performance and frame rate(but that also depends on the
game).

The sweet spot is always going to be application dependent.
If you routinely deal with large sound files, picture files or database tables or you are hosting one or more virtual machines then more RAM
will improve performance - its not all about "gaming"

I assume the Performance Monitor will show how much memory is in use, and also show the amount of paging activity.
If there is plenty of free memory and not a lot of paging then adding more memory may not make much difference.

It's an Intel. It should be quite resistant to shaming :-)
Some of his memory space will be dual channel now. That
should count for something. If it were to make a difference,
you might see it in a 7ZIP compression run (number of compression
threads times 600MB, during Ultra compression). The dictionaries
living in the dual channel section should be a bit faster.
But testing this scenario, is generally a pain in the ass. You
can't tell what's going on when you run some of the tests. (Where
the test element is sitting in the memory space. There is virtualization
and renumbering going on.)
One test I did long ago, was to modify memtest to dump bandwidth
numbers for various areas of RAM. And the values I measured were
like this:
+----------------------------+ 900
| single channel memory area | 900
+----------------------------+ 1400
| dual channel memory area | 1400
| | 1400
+----------------------------+ 1400 <=== the dual channel isn't quite twice as fast
But modern computer design, just tends to pave over that sort of detail.
To the OP, it would feel like a "transition from 16 to 24" and that's
about it. Any unevenness in speed, might not be (reliably) measurable.
The Yahoo News page opens with the same speed it always did.
Paul
I was under the impression that the os filled all unused ram with its
pages, thus speeding up the system in general. That is, if its in
memory its fetched much faster than on disk. Your opinions...
