Maybe time to get one of those fancy new Raspberry Pis...
I picked one up when they launched, but did not install a 64bit os [emoji23]Quote:

This got me thinking about perhaps building an arm/linux cruncher. But instead of going for the cheapest solution (RP4) which is based on Cortex-A72 (announced in 2015), perhaps there is something more powerful and newer. Are there any boards or computers based on anything more modern than Cortex-A72?
The Snapdragon 845/850 is based on the Cortex-A75 which came out last year. But I find only android devices with it.
Edit: Found one, the Lenovo Yoga C630. Looks like ~$700 new, or ~$500 on eBay. Yikes. That is at least 5 of the 4gb RP4 with all the extras. I guess all that cost is due to things like the display, keyboard, etc. Back to the drawing board.
If your looking for a decent arm machine you need too look at thunder x, just don't mind the prices :D

On another note I have my 4 overclocked to 1750mhz running solid for 2 days on universe@home compared to my other pi's
3b avg 8 hours
3b+ avg 7.25 hours
4b stock avg 5 hours
4b @ 1750mhz avg 4.25
As far as I can tell, unless you want to spend thousands of dollars on a ThunderX2 server, the only alternative is RP4. Finally a 2gb version showed up as available on Amazon, so I bought it. I kinda think they are lying...

This is kind of interesting bit still about $400 for. Full build.

My RP4 arrived. Which linux do you all use for crunching? Raspbian, Ubuntu, or...?
I'm using raspbian, just be aware it's only has 32bit support.

Well nuts. The 32bit raspbian OS mis-identifies the CPU as ARMv7 instead of ARMv8 which is what the RP4 has. Which means that BOINC tells projects that it has the wrong CPU. And I can't find a 64 bit linux. Ubuntu hasn't released their OS for RP4 yet. No ETA either. I think I just bought an expensive paper weight.
Check Aarch64. Waiting for Raspbian could take years.Quote:

I installed Arch. But it also seems to report to BOINC ARMv7.Quote:

Yes, Aarch wasn't a typo, however now that i'm looking at it again, i can't find the same info i found when i originally posted it. There's a Gentoo 64 that also works but might need a few tweaks. I don't have a RP4 though. Was just trying to be helpful.Quote:

For now, I have it OC to 1.6ghz and running Einstein.
Maybe this would work?
