    Phoronix: Gigabyte AM1M-S2H

    The Gigabyte AM1M-S2H motherboard is an AMD AM1/FS1b motherboard that's sized for micro-ATX enclosures, offers a fine set of budget features, and costs just over $30 USD.

    Wow these components are priced incredibly low, for ~$100 USD you can make a decent HTPC.

      There is a selection of these mainboards around now, also Biostar has some, ASRock and so on. Most of them are in the 30 - 50 Euro price range. It actually would be a bargain if...

      There is though the usual limitations of the LM_Sensors / hwmon kernel drivers not finding any of the motherboard's hardware sensors
      Well, this is the reason why I am curious what chip exactly it is. Michael, you have physical access to all these boards. You could name them. Because vendors often forget to name them. In this review you just wrote "ITE" chip, but ITE makes a lot of chips. Some are well supported, others are not supported at all.
      Actually it doesn't have to be the fault of lm_sensors / kernel. Sometimes it seems impossible to find a data sheet for certain chips. So this would be then a little bit like Broadcom WLAN chip in a laptop. Just a useless brick. No docs, no driver. And in this case it is soldered and you can't exchange it.

        Memory
        - 2 x 1.5V DDR3 DIMMs
        - 32MB Maximum Memory Capacity
        - Support For DDR3-1600/1333MHz memory
        - Support for Extreme Memory Profiles (XMP)
        32MB memory capacity, is slightly less than what I'd like on my system.
        Also, is it even possible to get less than 1GB DDR3 modules?
        :P

          That's not entirely true. (uploading this post using a broadcom wlan chip)

            Wrong photo

            I believe the last photo (page 3) is a different motherboard.
            For example the PCI-Express slots are missing.

              Socket FM2/FM2+ is a better choice. Better performance, Overclocking, Moderate gaming, Dual channel ram.
              And you can underclock/undervolt to 45W mabye less and keep a lot of the performance.

              But if it all boils down to Watts and you aren't going to be gaming on it much Kabini would make an awesome near silent media box that could play a lot of older titles. Be sure to get the fastest ram possible cause you only have one channel.

                VGA and PS/2

                I can't believe that these ports are still being included.

                Why not a DVI port and two more USB ports? Its been a decade since I've even seen a PS/2 mouse in any store, and VGA is just this legacy cruft that can be axed and nobody would miss it.

                (total, 1 HDMI, 1 DVI, 6 USB)

                  And you don't need any of that for an HTPC. I get the impression socket AM1 is designed to compete against the ARM HTPCs. It costs roughly the same and offers roughly the same performance, but offers a lot more bonus features (like more SATA ports, more USB 3.0 ports, PCIe slots, more OSes to choose from, etc), while sacrificing physical size and power consumption. I think this is a nice tradeoff, because it isn't a direct competition to the ARM HTPCs, it's a distinct variation.

                  Well, it does have USB headers on-board. I do think its weird to include PS/2 but it probably didn't cost anything to add it. I still use PS/2 whenever I have the opportunity - might as well if I've got the devices and the ports for it.

                    Agreed

                    The capture of the output from "sensors-detect", even in it's "short form" that avoids "poking sensitive chips" on certain video cards & chipsets, would provide some insight into this unknown ITE chip.

                    The "sensors-detect" method is easier and less likely to void product warranties, assuming Michael bought the board rather than it being a "review sample", than asking Michael to peel off the heatsink that hides the ITE super I/O chip.

                    Now that comment begs another question: "Why does a super I/O chip even need a heat sink when most if not all boards that I have seen in recent memory lack such items on those same types of chips?" The circuit diagram in the more densely illustrated and commented online PDF manual does not hint at any extra functions in this chip.

                      Good question about the heat sink. My guess would be that they expect the boards to go into compact enclosures. A heat sink can make a big difference in such an enclosure.

                      As to the ITE chip, maybe Micheal can work up a list of boards without this chip. On the other hand you can't expect instant support for new hardware. Maybe Phoronix needs a compatibility test and report. It has already been demonstrated that these boards need the newest kernels. & etc.

                        2 SATA ports, eh?

                        First I was like "oh this AM1 thing look great for a low-powered thing to replace the motherboard/CPU in my NAS/firewall 24/7 box" but then

                        > 2 SATA ports

                        not even enough for RAID5.

                        The low power-usage would make the AM1 platform a really great choice for NAS systems and small servers and media players and such but *2* SATA ports makes it a non-choice and that's kind of sad.

                          does it support other power sources? say, notebook power adapters...

                            You can't have everything. I still mis the parallel port on hardware these days as it is awesome for hacking, CNC and machine control. However these days that means an extended product via an expansion board.
                            not even enough for RAID5.
                            Mirrored RAID might be viable. This assuming that you can plug in a big enough flash drive into one of the other ports. It does make you wonder what people where thinking though, especially with the other supported ports included.

                            ASrock has a board with 4 SATA ports and a Mini PCI Express slot. So if you can find a SSD that fits in the Mini PCI Express slot you could easily make a nice 4 device raided NAS. As a side note this makes me wonder about what the chip really supports SATA wise.

                            One shouldn't be that sad as there are many boards out there supporting AM1 now. It is just a matter of choosing the right one for your projects.

                              A quick look on Newegg will show you a number of boards some of which do have DC input. Unfortunately the specs aren't well done. I'd really want to see a DC input solution that can handle 24VDC as that is an extremely common power supply size in the industrial world.

                              In any even shop around, lots of options out there.
