Uh... It's my server.
PSA about mini PCs: They might not come with adequate cooling for RAM, leading to potential data corruption.
(I'm in the middle of troubleshooting/fixing overheating RAM causing memory errors, will post on /c/selfhosted when I have more conclusions).
TLDR: Bought 3 Minisforum HM90 mini PCs (for Proxmox), equipped them with 64gb (2x32gb) RAM, with a different brand RAM in each PC. All 3 give sporadic errors in Memtest86. The RAM overheats due to the 2 SSDs mounted in the lid blocking natural airflow. With the lid off, or an extra fan installed, there are no errors. The errors were very sporadic: 1 PC gave errors after 1-2 passes, then almost 24hours. Second PC gave errors after more than 24 hours and some cases more than 48 hours between errors. The last PC gave hundreds of errors on the first pas. To be fair, memtest is a synthetic test and the RAM is unlikely to see 100% utilisation in real life, on the other hand the two adjacent SATA SSDs and the NVMe SSD are completely idle during memtest, and will generate extra heat during production use.
Take this seriously, people. I've been there and it caused tons of issues on an older server of mine. That's why I was very adamant about my current system having built-in error correction for its RAM.
Had an NVME fritz out on me on a passively cooled NUC because of thermals, I suspect. That sucked.
Same. It seems weird not to mention that in the article, since it`s a very popular use case for them.
Like others have said, RPS is a gaming site, not a general purpose tech site, so it makes sense that they limit the scope of the article.
Mine as well.
Works great as a NAS controller, multimedia server and basic web server. Also works as an emulation server for older systems. Not so good for gaming, but there’s a LOT of computing that isn’t current gen game, audio or video editing, which are the three areas where most minipc rigs will fail.
Just make sure it gets enough cooling - run a temp monitor.
