  • Zotac NM10-ITX

    So I'm now on my second board.

    It's all built and populated with the Broadcom Crystal Vision HD mini-pcie, U-Blox mini-pcie gps and, mini-pcie wireless card (factory)

    Only problem is it won't boot with the M3-ATX power supply! Only from a desktop supply. It will reboot if you hot-add the cards but not boot. Damdest thing. I wonder if my M3 is bad, but it boots my other rig, and works fine on reboot.

    I finally thought I had the most complete rig and now this grrr.

    Sounds like your new rig is drawing more juice than your M3 can deliver, try pulling those pcie cards, and the HD and see if you can post then.

      jdwk is 100% correct. More power draw than the M3 can handle.
      Have you looked in the FAQ yet?
      How about the Wiki?

        See I thought that too, but it handles it fine it is just rebooted. Also the only power additions are the broadcom decoder card and gps chip. The max a mini pci device can draw is 1A, so 2A does not near put me over budget. Also if the device is moved from one slot where it boots fine to the other it stops booting. So I'm confused.

          Wait, why are you unplugging things from the motherboard while it's running? Are you going to do that while you're trying to drive to get your CarPC up and running?

          Are you sure you added up EVERYTHING? INCLUDING the motherboard? The processor? All the devices plugged into the motherboard? Anything else running off the M3?

          Everything works fine with a different setup, is that setup LESS power than the Zotac setup?

          I'm with DP and jdwk - you're drawing too much power (even if it's only at boot) to use that setup. You're going to need to beef up your PSU.

            One thing to remember:
            When you're powering on from cold, there are some devices (HDD & optical drives, I know for sure) that draw more power at startup, as they have to spin up and such.
            They wouldn't need that extra burst of power when doing a warm reboot.

              Yep thought of that too, I have zero optical devices and HD's connected.

              I also thought the same about power load, So I just swapped the WiFi for GPS (which draws less) and same problem.

              Also when the systems's live I plugged gps into the one slot system finds it fine. I try the other slot it's not recognized.
              (btw Mini-pcie == USB so you can hot plug it.)

                Okay, that sounds better! I must've misread in the beginning because I thought you were pulling some card in and out and I'm on the other end wondering how everything is still happy!

                I still think it's a power requirement issue. I know it's an Atom setup, but it just seems like not enough to give it that initial boot.

                  Just had a fascinating conversation with zotac tech support:

                  Me: Any idea why moving the gps card from one slot to the other and the system won't recognize it.
                  Support: There's only one slot.
                  Me: No there's two, here's a link to the pic of your product. (two mini-pcie slots clearly visible)
                  Support: Right only one slot.
                  Me: Umm you realize the wireless module is removable right?
                  Support: Yes that's the only slot.
                  Me:
                  Support: I can see this is going to be an education for me.

                  After 30 minutes I end up having to e-mail tech support. This makes me wonder who's answering the live chat tech support. And after sending him copies of the spec sheet showing two mini-pcie cards he thanked me for helping. Anyway he's going to track down the power requirements for each rail 3.3, 5, and 12.

                  In my professional assessment I believe they have issues, because just moving a single card from a working slot to another makes it not work. This eliminates power as the culprit and makes me think they FUBARED the wiring on the extra slots... or the BIOS.. or the power supply.... or....


                  Wow

                    Re:

                    Isn't the Zotec system a 19V system and isn't the mt3 only verified at 12v? wouldn't it be better to try the cnx p2140 which i'm pretty sure can handle 20v out? Just questions, interested to see how this goes for ya.

                      Could be one slot is locked by the manufactuerer for a wireless module, this is pretty standard. Sorry the tech support is an idiot in silvercity, nm that just bought a 10 gallon hat cause they thought it was fashionable.

                        In turn:
                        No the zotac production model is a 20-pin ATX.

                        That's the irony the card that the factory wireless module is NOT causes the problems. It works fine in the wireless slot.

                          Hello Guys,
                          I tend to differ that it's power-capacity of the M3-ATX that's of concern here. I've run a lot more hardware than a mere Atom setup on only 120W......and the M3-ATX can provide peak-power of up to 150W.

                          There is something else at play here, and most likely a problem with the motherboard timing-requirements, similar to older M2-ATX psu's.

                          Will investigate this one a bit further to see if we can get down to the crux of this one.

                          I would reckon a fully populated Atom setup, like this one, with HD, slimline optical, and maybe Wifi module, should draw no more than 70W-80W startup (50W-70W running).....

                          @ Steven: You may most likely not be able to populate the WiFi pci-e slot with anything else tha a wifi module, there are manyu boards that has this "locked" to a specific type of module, I found the same in motherboards on IBM laptops.

                          Those slots might simply not be wired to accept the full compliment of pci-e compatible cards, rather just the wifi-subset.

                          Probably the reason why the tech-support said you had only one pci-e slot that could be populated with anything.....the other is locked to wifi.

                            As added info I also have a PCI-x1 -> mini pcie adapter I've been using and it yields the same results as the other mini-pcie slot, insert anything and it chooses not to boot. Unless its the factory wireless card.

                            Sadly I may have to set this aside for a week or return it to Newegg. If my Phd adviser finds out I'm spending time on this, well it's not research, so not getting fired is good.

                              Please post a link to the adapter you've been using, I've search all over and found nothing to convert sata or pci to mini pcie.

                              thanks!
