Question about memory for a Dell

[Stephen Partington]

I would be fascinated by seeing Linux running on that level of an arm SoC
instead of the glorified mobile shoved in laptop silicon.

For ram, My suggestion is to match the speed = to or just above. The modern
ram is semi programmable now which makes it flexible, and to some extent
dynamically flexible.

If you do the same match the SPD timings and latency, as you want to at
least keep the same level of performance on your new ram compared to the
old.

Otherwise, you can push things about all over the place without much issue
(as of ddr3 and later) unless you are overclocking or somesuch, which it
sounds like you are not. This is from personal experience with the
Optiplex 7010.
