This fanless PC has four HDMI ports, up to 64GB of RAM, and support for two SSDs

The Maxtang SXRL-20 is a compact, fanless computer designed for digital signage applications, but it could also be a good fit for some home users thanks to its support for user-replaceable memory and storage, better-than-bottom-of-the-line processor, and silent operation.

The little computer is available now from AliExpress for $479 and up and features an Intel Core i5-1235U processor, four […]

A recent discovery by Eclypsium's automated system, Automata, revealed a significant vulnerability (CVE-2024-0762) in the Phoenix SecureCore UEFI firmware used across various Intel Core processors. This flaw, with a CVSS score of 7.5, could lead to a buffer overflow and potentially allow attackers to execute malicious code. Initially found in Lenovo ThinkPad models, it affects multiple versions of Phoenix firmware on Intel processors, including AlderLake, CoffeeLake, and others. This widespread issue underscores the importance of UEFI firmware in device security and highlights the risks posed by vulnerabilities in the firmware supply chain. Phoenix Technologies addressed the vulnerability on May 14, 2024, but given the complexity of the supply chain, many devices may still be at risk. Users are advised to check for firmware updates from their device manufacturer.

So, lately I have been tinkering with my home server set up. After a few years of using my old Lenovo Ivy Bridge era server as a home server, I decided it's finally time to upgrade it. While it was fun to use enterprise-grade equipment I got on the cheap, its power usage & restrictions started becoming a major issue.

In search of a cheaper home server build, I was inspired by a couple homelab YouTubers like @CraftComputing and looked into some Erying boards and ended up with a board with an Intel Core i5 12450H ES chip and boy was it an adventure.

Been having this board for over a week and the great news is that the chip performed very well, it's super snappy. Those 4P + 4E cores ran laps around the old 12x Ivy Bridge Xeon CPUs that the old Lenovo server had. Having the built in graphics for Intel QuickSync has been amazing for transcoding & serving media. The fact that I get modern I/O like NVMe & USB3.x is a godsend as the old Lenovo server only came with USB 2 & didn't like it when you plug in any uncertified PCIe cards.

Now, while the chip ran great, it wasn't without its faults, it is an ES chip after all and the board has its quirks too. The biggest issue of all was that for the past week, I was experiencing hard locks whenever I try to do large file transfers to NVMe SSDs or hard drives connected to an HBA plugged into any of the PCIe slots. After hours of troubleshooting, turns out something about the Debian 12's stock kernel made it constantly hard lock. Using a newer mainline kernel (6.7.7 as of writing) provided by Zabbly (@stgraber) solved the issue, machine is now very stable, haven't been able to recreate the hard crash issue.

While not a major issue, found it weird that the motherboard didn't like the 400W Corsair PSU that I originally wanted to use but worked fine with the 400W Cooler Master PSU, not sure why as both PSUs work perfectly fine on other systems.

Another quirk that I discovered is that in Windows 11, the E-cores are stuck at its full clock speed and can't downclock at idle. So the E-cores were all doing 2.7 GHz when there's no reason to do so. This is the likely reason why the system idled around 60-65W compared to about 30W in Linux.

All in all, this Erying board has been quite interesting, it performs well when it does and it was amazing to get an Alder Lake CPU + mobo for only US$99. I knew that ES chips came with its quirks & I've been troubleshooting computers most of my life but I wouldn't recommend it for anyone who is hosting anything mission critical or put it in a system for anyone who isn't tech savvy and/or loves to tinker/troubleshoot.

As a homelabber build, the idle isn't great at 30W, haven't been able to get it lower than that, probably need to tinker with it some more. If you don't need space for many hard drives, something like the HP EliteDesk 800 G3/G4 would be a better buy if you need low idle. However, if you live in an area where electricity isn't expensive, like something interesting, love to tinker and want something super cheap, this Erying board is hard to beat.

Unsurprised that #Intel #AlderLake #12thGenerataion #GPU is not supported by "drm-kmod" version 5.1[05]. That ("device=0x46b3") is supported by version 6.1 ...

... by one count need #FreeBSD-CURRENT currently to use version 6.1 ...

#GPU_driven_CURRENT_use🙄😒

... so, few months⏳ (12 is also a number) to land the support in 14-STABLE?
