  • Is this the board? The VRM situation looks pretty dire, but I wouldn’t think that’d be an actual problem. Also why do you have C states disabled? That’s not going to be helping your VRM situation.

    Also what does your CPU cooling situation look like? Do you have a tower cooler that blows air over the VRM, or water cooling that leaves the VRM baking? Also generally for best performance you’d want xmp/docp/whatever the other thing is turned on. It’s free performance if your RAM supports it.





  • All we want is a page that shows various stats about work related things. They refresh every 20 minutes to get the latest info. But the most common point of failure is the network. Wired PIs seem fine, but wireless? Nah.

    The PIs are set to fully reboot once a week, but even that doesn’t work. At least once a week at least one will just disconnect from the network and not reconnect. I set up something to restart the network service since I found out that’s what was failing, but that doesn’t fix all of them. Sometimes they’ll just completely lock up. So at least once a month someone will have to manually reboot one of them. Most are in easy to reach places, but a few require some OSHA violations to get to.





  • Raspberry pi’s are unreliable POS. We use some at work to just display a static web page that refreshes a few times an hour and somehow they fail at that. They’re good enough for us since we’re just an office showing some stats. But this is proper digital signage.

    For something like this where you really need 100% uptime (except for this) there’s a whole army of specialty PCs built for this role. Passive cooking so there’s no fan to fail, beefy over built power supplies, and usually some built in special IO. They’ll usually have hardware watchdogs too, that’ll reboot the system if it’s not responding.
