From the POV of settings do ARM cpus behave like x86 cpus?
Eg. You get more CPU production if you don't set the CPU to 100 percent?
I am running 4 Kindle Fires, 3 with 4 cores, 1 with 4big/4little cores.
These are dedicated to Boinc machines.
Just now I have set the smaller 4 core machines to use 4 cores. But cpu-z reported slower processing speed on the big/little machine at 8 cores so I am back to 6 out of 8 cores on it.
Any ideas?

For the most part a ARM core can be viewed the same as an x86 core.
They just crunch slower because the clock speeds are not as high as x86.
Also still have to obey the thermal and power limits just as you do with x86. When exceeding the limits the OS throttles the cores to get back into compliance. If you stopped the auto boosting in the OS and architecture and used a lower fixed clock to keep from throttling you should be able to run 100% cpu utilization.
I have switched all the 4 core Fires to 75 percent (3 out of 4 cores).
Hope to pickup a little processing speed.

Given the lowest common denominator of tasks a Boinc CPU can run.
What are your favorite CPU projects?

I'm not sure what this sentence means practically. can you elaborate on the intent of this sentence? realistically any relatively modern x86 CPU is capable of crunching nearly any BOINC project's x86 CPU tasks as long as you meet the requirements of the specific app (OS, instruction set, etc).
I like Universe@home. each CPU task takes around an hour or less to complete, and doesn't take up a huge amount of system memory.
My backup project is TN-Grid. those tasks take a bit longer to run around 3hrs per task still with low system memory use, and awards much less credit (total) than Universe if that matters to you.
My favorite (and only) CPU project is Rosetta@Home, as my current professional research is connected to protein dynamics, protein folding, and protein docking. Unfortunately, R@H tasks require 9-10 hours to complete using a MacMini 8,1 (hex core i5). It is hard to maintain a consistent inventory of R@H tasks to crunch, unless you run VirtualBox. At any given moment, 15-20% of my available CPUs are idle while waiting for R@H tasks.
Good luck!

It's been awhile since I loaded Boinc on my own ChromeBook but I sure didn't do all that stuff. Yes I went into Developer mode but then just downloaded and installed Boinc and it runs everytime I turn the machine one, which is only when i go on trips right now. Now mine won't attach to some of the 'Science' type projects because it says there's a problem but it crunches Einstein BRP4 tasks just fine and other projects as well as long as they have an application for the cpu. The cpu is an ARMv8 Processor rev 2 (v8l) (4 processors) and the OS is Android 4.19.185-29738-gf8e4fd700b66 (Android 9). I haven't turned it on since my trip in July.
It has occurred to me that having a Ryzen 3950x CPU emulate the performance (not the Pcie lanes) of an equivalent (16c/32t) EPYC CPU should be fairly easy.
Turn off PBO. Turn off CPU boost. Put an Ryzen 3900 CPU cooler on it.
Why? Because a giant CPU air cooler only fits inside a really tall case. And is very time-consuming to install or remove.

It is how I run all my Ryzens. Just pick a fixed multiplier and set a voltage offset sufficient to run whatever clock speed you choose and let it run. Never look at it again.
