    I have never tried 3 DIMMs! Are you trying to get 96GB or something?

    I actually had 2x 16GB Samsung DDR4 modules fail on me today. Very bummed.

    Its a dual-channel design. Run 2 or run 4 and you won't see any difference (assuming you put them in the right slots, of course). Run 3 and you cut the memory bandwidth in half, half of the time.

    In general, a very bad idea.

    @Patrick: I will! Never thought of posting it there. I wanted to fine-tune the topic, so no need to bring back the old post. Thanks anyway!

    Currently booting just fine with 96GB but not sure if it was a bad idea or not and now much it affects performance.

    It will boot and function perfectly. Performance will be poor for any memory intensive task.

    I'd really love to see some CPU Passmark numbers on these new 12 and 16 core chips so I can compare their potential transcoding power in order to know which will be the best value for me to replace my 1540 with.

    Can a single core handle 1 stream? Also, why transcode and not directstream?

    I'm not sure what you're asking exactly. With Plex, transcoding is a necessity if you are supporting a lot of different streaming clients as they don't all support the same file formats. I have Roku's, Chromecasts, Androids, iOS devices, Smart TVs, Tivos, etc. all connecting to my Plex server and thus my CPU gets a lot of workload. In addition to the live transcoding, I also have a good amount of background transcoding happening whenever a Sync is kicked off for offline availability. The faster I can get those transcodes done the better.

    I have Roku, iOS and Android devices and they all seem that they can directstream which means very little CPU used. Although the Roku has a bug which causes it to hang sometimes if I enable this. So I almost always transcode audio for it.

    What I asked specifically was "How many cores (the CPU has 8) are required to handle a single client" or worded differently "how many devices can your 1540 handle?"

    What type of files are you streaming (what codecs?)?

    My CPU seems to be able to handle 5-6 transcodes at a time. I'll often have upwards of 10 streams going at once, half of which are transcoding. But if anyone tries to kick-off a Sync while any live transcoding is taking place that process will take hours.

    That's not a board - that's a monster. Ant-man of server boards. Need pricing!

    Man that board makes me want to roll my own switch (something I've never done).

    Shouldn't be hard. Looks like it comes with the software already bundled in. See this line from the product page:

    What was the indication that they failed?

    Then

    Those are actually GREAT error messages because I was able to locate the non-working modules very quickly.

    I spoke with the ADI Engineering guys at IDF15 and they told me about this. ADI Engineering is who makes the pfSense branded appliances that are not Supermicro appliances.

    Their basic idea is that many of the BMC functions are very close to a subset of what pfSense has, and there are only a few relatively easy things to add.

    I did also speak to a few vendors over the past six months or so about when we will see an AST2400 replacement given that they use a TON of power compared to these low end SoC systems. The feedback was that the Aspeed guys are good at fixing issues quickly and with that good of support, why make a change.

    I would offer that a Raspberry Pi 2/ 3 can easily outpace an AST2400 from a SoC performance standpoint, it just needs a PCIe connection and the software side to mature.

    Would a Celeron J1900 board work? ... I had a check for fun and those come with PCIe 2.0 x16 (So 3.0 8x speed) and room for 16GB memory and the board and CPU was listed at around 63 euro (x2 Rpi3) and TDP 10-15W.

    Edit: The mem is extra though unlike a Rpi/C2/Xu4.

    @Patrick very interesting. I wonder if SM would provide similar messages. Also would wonder what would happen if this happened while the system was powered up and live.

    Sorry to hear about that!
