    SOtM Launches sMB-Q370 Motherboard

     

     

    Wow, what a week for product announcements. First HQPlayer integrates Qobuz, then VOX integrates Qobuz, then AURALiC integrates Amazon Music Unlimited. Now, SOtM launches its own motherboard named sMB-Q370. For many audiophiles this will be beyond geeky, but for many others this is really a neat product. Building a motherboard is a huge undertaking to say the least. 

     

    I can't wait to see this one in the wild and to start getting feedback from the Audiophile Style community as more people integrate this motherboard into their systems. Very cool indeed.

    sMB-Q370 User Manual

     

    MSRP $500

     

    From SOtM:

     

     

    The sMB-Q370 is a high-performance computer motherboard specially designed for audio. Since this product is equipped with an Intel series CPU, it can replace all commonly used computer motherboards.

     

      There is a variety of motherboards and network audio players on the market that meet the high-performance specification and certainly there are a variety of choices too, but the products using these general motherboards are designed simply for fast operation to accomplish processing of large-capacity music files or converting music files to high sampling rates such as DSD. You won’t be able to avoid the limitations of the sound quality, which will be revealed clearly if you use such products as audio players.

     

    Even if the sCLK-EX, tX-USBexp, sNI-1G and others are installed and used on these general motherboards to improve sound quality, the source itself cannot be compared with that of a system using the audio grade motherboard, sMB-Q370.

     

    So, using the sMB-Q370 means starting a new beginning to your listening experience.

     

    You would simply get clear improvements in every aspect of the music including the background, texture, tension, resolution, and location in space of the music with the sMB-Q370 designed exclusively for audio. If you close your eyes and listen to the music, you will feel as if it is the beginning of a new world with the subtle reverberation of instruments resonating in the dark.

     

    In order to implement audio performance that exceeds the limitations of general motherboards in the existing market, the sMB-Q370 has applied a large number of audio parts that have been verified by being used in SOtM products for a long time and is designed to minimize the impact on each element inside the board to reduce noise as much as possible. Although this explanation may seem very simple, it can be said that it is the culmination of the many technologies that SOtM has implemented so far. The very deep and in-depth accumulation of technologies has made this possible.

     

    In addition, the sMB-Q370 has all the features of an existing PC, so everything that was possible with a regular PC can be replaced to the sMB-Q370. A high-performance graphics card, various types of PCI express add-on cards, M.2 NVMe SSD, M.2 Wifi module, M.2 Ethernet port, SATA storage device, etc. can be installed to expand the performance and use of the PC. With this combination of scalability and low noise performance, the sMB-Q370 has no limits in the fields where it is difficult to use general boards, such as mixing and mastering computers for studios and medical devices that require 3D functions.

     

    If you’ve been looking for a high-performance motherboard that has the features you need and meets the best sound quality and performance ever, we can assure you that there’s no need to worry anymore. The best performance, sound quality and expandability, all of these can be realized with the motherboard designed exclusively for audio, sMB-Q370.

     

    Now, it is the time to make the choice that will bring your system to its peak with the sMB-Q370.

    yup, if you have a chance, please try to use the sCLK-EX connection in future :)

    Its great that you can add the sCLK-EX at a later date 😎.

    Hi all,

    I have had the pleasure of using the SOTM SMB-Q370 for the last few days. Let me cut to the chase: I am very pleasantly surprised by the improvements in resolution, soundstage size and transparency. This is without the enhancements from the clock board. I expect that the clock board will takes things to a new level and I will report on that when/if the time comes.

     

    Going with the SOTM SMB-Q370 can be a complicated choice because we've learned several key attributes to focus on for SQ:

    1. Going CPU direct is best.

    2. Robust VRM is great for SQ.

     

    • I am here to assure you that my i9 9900k glides wonderfully and without issue in the neighborhood of 4.8ghz (down slightly from 5ghz). The VRM is doing a wonderful job.
    • Do not feel negatively about the fact that you will utilize the PCH more. The SQ from this board is significantly better than the already wonderful Designare (which allowed me to go CPU direct for my JCAT USB XE, Femto NVME, and, Startech Fiber NIC).

    This sounds somewhat like a sales pitch or "buyers justification", but I am simply sharing my astonishment with this board. I was a bit underwhelmed for the first 12 hours or so. I had wondered if the board was overpriced and only offered a true benefit with the clock board. Let's just say I have paid more than the price of this board for other items that have had far less impact from 20 hours and onward. I believe SOTM when they say this board was built with audio parts that sound good. I am really impressed with what they've accomplished and I have yet to poke around in the bios to disable the features I will not be using (this should result in a further SQ uptick).

     

    I hope @MayfromSOtM can confirm if there are plans to release another board in the future with the same technology, but with support for newer CPUs. I was fortunate that I had not already moved on from the i9 9900k but most others on this forum have already done so. The i9 9900k is difficult to find new a this point, many of the CPUs on ebay have been abused by overclockers (I'm an ex-oc-er :D) so yeah, the older chipset limits the appeal quite a bit, which is a shame because this motherboard is ridiculously good and should have more widespread acclaim for what it accomplishes. I suppose its tough to answer this question now, as this could take away from sales of the current board. 

     

    Either way... SOTM did a wonderful job here and I am keen for others to try and share if they're hearing what I am hearing! Another post will follow once I've done some tweeks/breakin.

     

    Cheers,

    -Rob

    Great to read Rob!

    Great job Rob - Finally someone gave the SOTM a quality power supply and associated equipment to see what it’s really capable of - Bravo!

     

    I just wish SOTM would have done it justice to start with.

    What a coincidence, just this morning I was googling the i9 9900K to see what its price was only to find out it’s not for sale anymore. This hole week I was thinking about a new server what power supply to use and what motherboard etc. Nothing to serious still saving money my new house. What I do not understand is why SOTM made such an effort to design this motherboard but you can’t buy the top spec cpu anymore? How long will it take before the other cpu will become obsolete?

    I think Sotm started the development when 8th/9th gen were in its prime but by the time they were able to release the product to the market, the ship has sailed. Building an x86 board, as complex as it is, from scratch, even if you start with a reference board which all manufacturers does, takes a quiet a bit of time (and there are too many things that can go wrong) and I applaud Sotm's effort towards it. Now that they have the expertise, I believe supporting the latest gen proc will be easier for them, nevertheless still being challenging.

    Yeah their efforts are certainly admirable but I can only hope they are already busy reviced version.

     

    Edit: certainly with @Exocer  quality power supply findings.

    I’m using this smb-q370 since 6 months with in addition the superclock for the MB (no other sotm boards like Ethernet or usb). The superclock is powered by external 12v (uptone js2) and 10Mhz reference clock. CPU is a 9900k. The MB is powered by a ULPS from Pachanko feeding a Taiko DC/AtX. 

    im very satisfied with the performance of the server and good step forward vs my previous one.

    i also appreciate the support from sotm even if still not possible to make a solarflare NIC board working : this board is preventing the SMB-Q370 booting. We should probably find a solution. The bios is quite limited in terms of settings especially for cpu. One little trick, if you have multiple boot option, hitting F7 allows you to select the BBS screen to select your boot.

     

    Best Regards

    Which Solarflare nic? I tested my Solarflare nic for another AS member recently and it sounded very good. No boot issues.

    Hi, the Solarflare x2522. It boots fine on a supermicro x111scl-f. Just updated the solarflare’s FW and remove the PXE boot. Will try again later this week.

    8th gen 8086k vs 9th gen 9900k... hmm...

     

    Also Q370 only does dual channel memory.  So dual channel with 2x DDR4 sticks or dual channel with 4x DDR4 sticks?  Absolutely zero guidance on what is preferable in the manual.

     

    Is two sticks per channel worth it?

    Found the answer... 4 sticks will serve as dual channel. only.  In fact 4 sticks would likely make the memory controller work harder, so 2 sticks is best.  Makes me question why four banks was included.

    Standard MB customized by/for sotm and not fully designed from scratch ?

    Yeah I have the SFN 8522, which worked flawlessly with the SMB Q370.

    Thanks I did not find time to put the x2522 on the Q370. Will try to do today after FW and PXE adjustments.

    So I tried the x2522 with FW updated and PXE boot disabled, still same problem : no boot. Would need to find a SFN8522

    The hdplex harness is soon to be replaced with hand drawn 99.99% solid core silver cabling.

    @Luvdac did you replace the harness to good result? What cable exactly did you end up using?
    what do you use to and from the Jcat nano?

    thanks!

    Yes. The harness is pure silver as are the cables from the nano psu's to the cards. I can hear the difference for the better. More relaxed ( more absence of noise/digital harshness). Recommended.

    @MayfromSOtM seems the D8260T36 firmware has been released. Any chance to know the changelog ?

    I installed it but did not see clear changes (CPU frequency management for example).
