The AM1 Kabini Motherboard Preview: Analyzing the Hardware

ASRock AM1B-M

ASRock’s first motherboard falls under the $40 mark and also represents a slightly different variation on the theme. So far no two motherboards have been alike, and the ASRock AM1B-M exchanges the higher audio and video outputs instead for more rear USB 2.0 ports and an extra fan header. On the face of it, this does not seem like a good deal compared to the previous MSI, unless you need extra USB 2.0 ports.

The AM1B-M seems to have a lot of spots unoccupied by connectors. This is mostly likely due to variations of products, where the cheapest tends to have expensive connectors removed to hit a price point. We see two SATA ports missing, an IDE pin layout but no connector, and also a DVI connection missing on the rear panel. In the middle of the board is also a USB 3.0 pin layout, suggesting that another model has an additional USB 3.0 controller as well.

What the ASRock AM1B-M also does differently to all the motherboards we have examined before now is include a COM port, LPT port and a TPM port on the same PCB. It would be interesting to see which niche that combination would be good for.

The PCIe layout uses the PCIe 2.0 x4 from the chipset in a full sized slot, with an additional PCIe 2.0 x1 underneath. Thankfully the SATA ports are alternate facing for removing locking SATA cables, and the placement of the 4-pin CPU connector also helps cable routing. The AM1B-M has three fan headers, one more than the others – two on the top of the motherboard either side of the DRAM slots, and a third on the bottom right.

The AM1B-M has four USB 2.0 ports on the rear panel, or what I like to call my happy minimum (installing an OS via USB helps with at least three USB 2.0 ports). That being said, the sole VGA connector looks lonesome, and the ALC662 audio codec is not a particularly good choice.
