Thanks, Paul. Not sure what this is exactly. Ark doesn't seem to specify anything
about channels other than the CPU accommodating 2 RAM channels. It has 4 cores and 8
threads. CPU is Intel i5-1035G1. I currently have 2 sticks of RAM (8GB and 4GB)
installed. My plan is to replace the 4 with another 8, same make and model.

That's dual channel. You can swap an 8GB in there and the
BIOS will run the two sticks, at the slower of the capabilities
of the two sticks. So if one is CAS12 and the other CAS13,
the setting for all sticks is CAS13 (slower). A difference that
small would be "down in the noise". You would not change out
all the RAM "just so it could be CAS12" for example.
To detect a difference, I'd start by running the 7-ZIP
benchmark. As it's sensitive to RAM.
0) Check user manual, for any procedural steps different
than the following RAM replacement procedure.
1) Benchmark the 7ZIP utility from
https://www.7-zip.org/
2) Shut down (full shut down, not sleep or hibernate).
3) Remove battery pack (so no power present in SODIMM slot).
4) Unscrew RAM access area. Pull 4GB. Insert 8GB SODIMM.
Put old SODIMM in antistatic container. Replace cover.
5) Install battery pack.
6) Boot and bench 7ZIP again.
That will give the largest improvement in performance,
if any is to be had. Most RAM characteristics are smothered
by CPU cache, but 7ZIP is one utility that relies on
all subsystems being at their peak.
To give an example, I have two processors here that are
fairly similar, except one has more cache than the other.
The one with more cache runs 7ZIP 50% faster than the other.
The effects of your RAM upgrade should be smaller than
what happens with cache differences. But hopefully, still
a measurable difference.
Many other test cases might not see a diff.
