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.

Cue the probable: Apple may be expensive, but I rarely have failures with it. My wife's 2011 Macbook Pro was just updated with 16GB Ram and a 255 GB SSD - it has no issues doing anything she needs it to. That being said, it is no longer "eligible" for "feature" updates via MacOS, although it is clearly capable of handling the load. 

I stick with Apple for my desktop (given the choice) and Linux for my servers :) 

My biggest heartache is seeing that the death of the hackintosh is on the horizon with switching to the ARM CPU set, but who knows? If they can get Linux working on it, and I've seen large interest in getting Linux on the M1 chipset, maybe they'll find a way to put MacOS on off the shelf components as we've been able to do with x86/64

I definitely won't be buying an Apple anything.  I can't afford them.  Dmidecode tells me the DIMMS are 4096 MB, 1600 MT/s and made by Hynix/Hyundai. That makes it easy to figure out what I need.  Thanks to you and Todd Cole for replying.  I

Memory hasn't been as finicky in years than I found it 10-20 years or more now, most seem fairly tolerant as long as you match up specs.

If using windoze, install cpu-z and just match the specs, speed, unbuffered, ddr-class, etc.  Likewise using dmidecode under linux, just match spec what is there now.  If using a mac, just pay whatever overpriced ram apple wants to sell you because you or your sponsor can obviously afford it.  Probably a better way under mac, I'm sure google knows most sticks are probably compatible there too realistically.

I do miss when there used to be the technology swap meets over in Mesa here to find old/dated hardware for stuff like this, I think that all moved to Craigslist, now Letgo and others, always ebay if nothing else.  I always buy used ram, particularly when talking the more pricey large ECC server stuff, really haven't had complaints personally doing so.  Last time I put 128gb in my desktop, I did so for around a grand from ebay getting old server dimms from a retired cisco ucs box, same memory, which from dell would have been some $8k of absurdity.

Recently I bought a Dell Optiplex 7010.  Today I started looking for
some more memory (2 4GB DIMMs) to put in it.  Some said it was for the
Dell while others didn't claim to be for a specific model.   I did
notice that the ones claiming to be for a Dell were about twice the cost
of those that didn't and I don't want to pay the extra if I can avoid
it. I'm sending links to a couple of the choices.  Can someone tell me
if there's any difference between the two? Thanks.
