Supermicro M11SDV-8C-LN4F Review AMD EPYC 3251 mITX Platform


Supermicro M11SDV-8C-LN4F Power Consumption

We used our pair of Extech TrueRMS Power Analyzer 380803 units to take measurements at different points of the Supermicro M11SDV-8C-LN4F use on 120V power in the embedded lab. Embedded platforms tend to spend more time at the edge in offices rather than in higher power data centers, hence why we do our testing at a lower voltage. Here are the figures:

  • Power off BMC only: 4.4W
  • OS Idle: 28.4W
  • 100% Load: 66.5W
  • Maximum Observed: 71.3W

These are solid results. The Supermicro M11SDV-8C-LN4F performs well and at a lower power level than many of the Intel Xeon D-2100 performance competitive solutions. In the embedded market, low power is key.

Final Words

In the embedded market, the Supermicro M11SDV-8C-LN4F is one we need to succeed. It would have been nice if it had a handful of additional SATA lanes and exposed the AMD NIC’s 4x 10GbE interfaces. At the same time, this is a conservative take on a brand new platform which we appreciate. Success for the Supermicro M11SDV-8C-LN4F and other AMD EPYC 3000 platform is key to ensuring supplier diversity in the embedded x86 market. When new security vulnerabilities like Foreshadow/ L1TF are found in an architecture well into its lifecycle, having another vendor that is or may not be vulnerable is important.

Beyond the supplier diversity question, the Supermicro M11SDV-8C-LN4F is a great platform. Supermicro’s inclusion of the higher-end Intel i350-am4 network controller means that the platform works out of the box on many distributions. Supermicro’s product team did a great job building a platform that scales with the AMD EPYC 3000 SKU stack while being an easy transition for its existing customers.


  1. Thanks for the informative review, Patrick. This board seems rather MPD to me. Four DIMMs, four SATA, four gigE. It’s not a storage machine: needs more SATA; it’s not much of a router: needs more gigE; it’s not great as a VM host: 128GB DIMMs are frightfully expensive. And any of these applications would benefit from 10gigE.

  2. Just a guy: I would guess this board is just a beginning in a set of boards from Supermicro build around this processor series.

  3. I’d prefer a single 10GbE SFP+ to quad GbE these days. The limited SATA isn’t concerning to me, it would be easy enough to add an HBA if one really wanted lots of disks.
    This would be a good upgrade from my C2558 if it had SFP+

  4. Is there any idea of pricing on these parts? I’m checking our typical SuperMicro supplier here and these parts aren’t even listed yet.

    @Bob these parts seem to have the same naming scheme as their Xeon D counterparts, so I would expect a TP4F suffix to have 10Gbit on board as well as (hopefully) some F variants for lower budget embedded appliances. The CPU performance/Watt is perfectly aligned with our edge caching use cases, so I’m eagerly awaiting parts and variants to be available.

    ive just bourght a M11SDV-8C+LN4F from poland and awaiting its arival. I gave 440 euro + shipping for it, to denmark

  6. Hello,

    Do you think that this motherboard will fit into the CSE-721TQ-250B chassis? This motherboard has the same dimensions as the supported Xeon boards, and the compact mini-tower chassis would be more useful (and quiet!).

  7. Did the RAM operate at 2666 Mhz? Page 16 of the manual ( states “When the motherboard is fully populated with 4 modules of single rank DDR4 RDIMM, the memory will operate at speed of 2133MHz”. It gives other cases where RAM speed is diminished, to the point where I’m not sure what configuration of ECC DIMMs should be used to get full 2666 MHz memory speed when using all 4 DIMM slots.

    Any ideas?

  8. Patrick, yes I saw you used 2666 MHz DIMMs. My point was that the motherboard manual implies that the board can only use RAM at a maximum of 2133 MHz when all 4 DIMM slots are used (see the section I quoted in previous comment). Am I reading it wrong? Were you able to verify the RAM speed?

  9. MNL-2172.pdf (page 16)
    “When the motherboard is fully populated with 4 modules of single rank DDR4 RDIMM, the memory will operate at speed of 2133MHz.”

  10. I’m not sure why you guys care about RAM speed so much. It’s standard that most servers, even the E5’s and big EPYC will downclock when fully populated. That’s normal. You can always manually set RAM speed. Easy. It’s working in the boards we’ve deployed and its what you’d always do if you cared about RAM speed. Some companies have their autotuning defaults to keep speed the same and give it fancy names. I don’t see what’s different with this one.

  11. €700+ for the board.

    Yikes. According o the domain name servethehome, this is hardly appropriate product.

    How many homes can afford that for just a MoBo + CPU ?

    For a budget solution, one might be better of with consume grade stuff, downclocked CPU and ECC compatible board…

  12. Patrick Kennedy:
    Fine. But it still caries hefty pricetag for what it is…

    Epycs are better binned than off-the-shelf stuff, I understand that.
    ECC certification is wrth af few €, too since it already is working in all chips, so it is only the matter of official stamp and perhaps one testing step more during production ( if even that).

    So, what is left on the board that is worth those extra €300-400 ?

    For us not-exactly profeesionals it seems better to look for off-the-shelf stuff.

    R7 1700 is cheap these days ( not much more than €100!) and undeclocked should churn much more than Epyc3000. On one elcheapo uATX board should work just fine.

    If I opt for ECC RAM, I’d have to narrow my board choices and use unbuffered ECC, but that’s OK for my useage.

    Or perhaps Asus, Asroc or Gigabyte might decide one of these days to dip their toes in these waters…

  13. If the board does not meet your needs, and that is a realization after reading the review, then I think that is a success on our end. Our goal is to present all of the features so people can make decisions. For some, the embedded part makes a ton of sense. For others, it does not. That is the same with any platform and we just want to ensure people have access to enough information to make that decision.

  14. Hi Patrick,

    I noticed the X10SDV-TLN4F motherboard (for the XEON D-1541) has x6 SATA3 ports, but this one only has x4. What would be the recommended adapter in order to make use of additional SSDs, as the CSE-721TQ-250B chassis has space for an additional x2 drives?

  15. This looks very interesting, however I see that vs Xeon-D this is not officially supported by VMWare, I found some comments around the web that it had some issues and some updates fixed them, but still is not clear to me how stable it could be. I primary will use it as a home lab server so I can afford a non-official support, however a partially support is not an option, anyone else had the chance to test this platform with a VMware environment (vcsa + nsx + vsan)?


  16. What is factored in when measuring the Power Consumption of these boards ?
    Is it just the CPU ?
    Or is it the entire configuration ?
    If so what Config is it ? CPU+Board+2xRam+1 Drive ?

  17. Hey Patrick, do you intend to review the asrock Epyc platform as well (EPYC3251D4I-2T)?
    The 2 boards are interesting, because they come with 2 10GBe, as well as 6 Sata ports by default, unlike the supermicro boards. It would be nice to see how that affects power consumption.

    Also do you think there will be ATX Boards with Epyc 3000 Processors in the near future ? Because cutting down their PCIe lanes with the mini-itx design realy sucks.

  18. Some information about idle power use to something like me who uses the platform in residential setting where the system is running 24/7, workload is bursty and idle power use is very important.

    With the following configuration I’m getting 22.3W at idle.

    M11SDV-8C+-LN4F with EPYC 3251.
    Stock fan replaced with Revoltec RL036 (mostly due to noise reduction, but likely it helps power use too).
    64GB DDR4-2400 RAM (2x32GB HMA84GR7MFR4N-UH)
    Only single gigabit network cable is connected. BMC is left unconnected.
    PSU is 120W 12V power brick (Chieftec CDP-120ITX).
    VGA is disabled via jumper (saves 1W)
    “powertop –auto-tune” has been run (saves 0.2W if VGA is enabled, 1.1W if VGA is disabled)

    The measurement has been made on console login screen of stock Debian 11 that had powertop installed. The power meter is not calibrated.
