ASRock launches Intel Processor N100 motherboards with 24-pin ATX connector or DC-in jack

ASRock has launched two new similar low-cost Alder Lake-N motherboards powered by a 3.4 GHz Intel Processor N100 quad-core CPU with the N100M micro-ATX motherboard featuring a 24-pin ATX connector for power, and the N100DC-ITX mini-ITX motherboard getting powered through a DC-in jack compatible with 19V power adapters.

Both motherboards have very similar specifications with support for up to 32GB DDR4 single-channel memory, M.2 NVMe SSD and two SATA drives, and offer multiple video outputs including HDMI, VGA, and DisplayPort (N100M only), Gigabit Ethernet, up to sixteen USB interfaces, PCIe slots, and more.

ASRock Processor N100 motherboards ship with a user manual, one I/O shield, two SATA cables, and two screws for M.2 modules. The company only provides drivers with Windows 10 64-bit and Windows 11 64-bit. There’s no mention of Linux in the description or user manual, but I can see a review on Amazon Japan (see below) where one user successfully installed Ubuntu 22.04 Server. Just don’t expect support from ASRock for operating systems other than Windows. The company also provides (Windows) utilities such as the ASRock Motherboard Utility (also known as A-Tuning) for system updates, and ASRock XFast LAN to prioritize internet applications, lower game latency, and so on.

The ASRock N100M and N100DC-ITX motherboards were initially announcedin May, but FanlessTech reports they can now be purchased around the world including Newegg (US) for $119.99 (N100M) and $129.99  (N100DC-ITX), some shops in Europe such as Amazon France, Idealo (Germany), or Inside Tech (UK), as well as Amazon Japan among others. More details including Windows drivers, user manuals, and other documentation can be found on the respective product pages for the micro-ATX and mini-ITX motherboards.

Thanks to “NewsTip” for the tip.

Update: The article was initially published on May 4, 2023, and updated once the mini-ITX motherboard became available for sale.

ROCK 5 ITX RK3588 mini-ITX motherboard

  1. So close, yet so far on the mini-ITX board. Why are they wasting multiple PCIe lanes that could have been used either to add two more SATA ports, for a great little NAS board, or to make the PCIe or M.2 slot a full x4 interface? This makes no sense at all.

    1. > to make the PCIe or M.2 slot a full x4 interface?

      If I understood it correctly (questionable) and the CNVio interface doesn’t utilize PCIe then both M.2 and PCIe slot could be made full x4?

  2. up to 32GB DDR4 single-channel memory


    What I’m interested in now is “Strix Halo” in a mini PC or soldered onto a motherboard, since it would be too big for AM5.

    Strix Halo = chiplet-based APU with up to 16 Zen 5 cores, 40 RDNA3 CUs

    1. Right totally, some rumour that might just possibly hit the market in two years time totally makes a joke of this actual real product using a released CPU

  3. Hi, can anyone tell me if this board can handle an Intel Arc 380? I want some low power homeserver to run OpenAI’s Whisper at home, almost all the time in a dedicated device. The Arc380 can run the big model, but I don’t know if the CPU would drag it down.

  4. Prices are not too bad actually?

    • 1x PCIe 3.0 x16 Slot (PCIE1), supports x2 mode, can boot system from NVMe SSD
    • ASRock N100M only – 1x PCIe 3.0 x1 Slot (PCIE2), can boot system from NVMe SSD

    I think this is backwards. N100M has a PCIe x16, while the Mini-ITX one does not.

  5. According to Intel’s own specs, 16 GB is the maximum amount of supported RAM by the N100.

    So how do they squeeze another 16 into it?

    1. Intel processors’ maximum RAM capacity as reported on Intel Ark has never been accurate. That seems crazy, but it is what it is. The only way to know for sure is to wait for somebody to test it.

      1. In fact it’s very simple, they’re segmenting their market, that’s a very common practice. They don’t want these chips to be used for very large setups, for which they’d rather sell much higher priced chips. So they just write what they’re willing to support. If you contact them saying “I’m getting trouble with my 32GB” they can tell you “that has never been supported”. AMD did the same with their Athlon-XP vs Athlon-MP 20 years ago. They were so much the same chips that the CPUID name changed when booted in a dual-cpu board! The vendor was totally amazed when I showed him after he told me “this will not work” 🙂 I used to have such a dual-XP (reportedly dual-MP) board as my main PC for 5 years or so, never met any issue, but this setup was not officially supported. You’re seeing somewhat the same with temperature ranges BTW: commercial and industrial chips most often are exactly the same, it’s just the extra testing (if at all) and the price that changes.

      1. True, but in the meantime, if you have a set that works, it works OK, no hidden issues down the road.

        My guess is that it a combination of size, latency and… quality of the chips on the DIMMs.

        I’m using 32GB with H2/H2+ and 64GB with H3/H3+.

        1. Already curious how many RAM you’ll be using on H4 then 🙂

          But at least today there exists no DDR4 SO-DIMM exceeding 32 GB anyway.

      1. We can buy N100 mini-pc with 16GB RAM for cheaper. As for scalable, the Asrock just have 1 pcie3.0 x4. I think it’s not that helpful.

  6. Hi,

    the N100M (and the N100DC-ITX as well) comes with an undocumented UART1 port (to be seen on the lower left corner of the N100M picture as well). Does anyone know the actual voltage level (1.8V, 3.3V, 5V)?
