    Biostar is ready with a trio of socket FM2 motherboards, based on AMD's new A85 FCH chipset, the higher-end Hi-Fi A85X, mid-range Hi-Fi A85W, and value Hi-Fi A85S. Biostar implemented some of its latest innovations on the two. To begin with, the thee feature Hi-Fi amplifiers for the analog channels of the onboard audio. Another innovative feature with the two is a bank of capacitors that make the board electrostatic discharge proof up to 15,000V. Find the furriest carpet to assemble your rig on.

    The audio solution combines a high SNR CODEC (probably ALC898) with an OPAMP circuitry that uses sound card grade electrolytic capacitors. The entire audio portion of the motherboard, including the rear panel jack cluster and front-panel headers, have a ground PCB layer of their own, that is isolated from the ground layer of the rest of the board. This ensures there's no ground layer interference from other high-current components on the board, a problem common with onboard audio solutions.

    The Hi-Fi A85X is designed to occupy a premium price point. It uses a 10-phase VRM to power the APU, which is wired to four DDR3 DIMM slots, supporting up to 32 GB of dual-channel DDR3-2400+ MHz memory, and two PCI-Express 2.0 x16 slots (x8/x8, when both are populated). Other expansion slots include a PCI-Express 2.0 x16 (electrical x4, wired to the FCH), three PCI-Express 2.0 x1, and a legacy PCI. Out of the eight SATA 6 Gb/s ports given out by the A85 FCH, seven are assigned as internal ports, and one eSATA. Display outputs include DVI, D-Sub, HDMI, and DisplayPort. The Hi-Fi audio solution (detailed above), four USB 3.0 ports, and gigabit Ethernet make for the rest of the connectivity. The board is driven by AMI UEFI BIOS.

    Moving on to the more affordable Hi-Fi A85W, which retains the two star features of its sibling, the board uses a simpler 6-phase VRM to power the FM2 socket. It supports up to 32 GB of dual-channel DDR3-2400+ MHz memory, and although it has two PCI-Express x16 slots, only one of them is wired to the APU socket, and is PCI-Express 2.0 x16. The other is electrical x4, wired to the FCH. The board has all eight SATA 6 Gb/s ports from the PCH arranged in a neat row of internal ports. Display outputs include DVI, HDMI, and D-Sub. The Hi-Fi audio solution, apart from gigabit Ethernet, and four USB 3.0 ports, make for the rest of it. AMI UEFI BIOS drives the Hi-Fi A85W, too.

    Lastly, there's the Hi-Fi A85S, the lone micro-ATX motherboard among the three. This one uses the same 6-phase VRM as the Hi-Fi A85W, to power the APU. Like the others, it supports up to 32 GB of dual-channel DDR3-2400+ MHz memory. Expansion slots include one PCI-Express 2.0 x16 wired to the APU, a PCI-Express 2.0 x16 (electrical x4) wired to the FCH, a PCI-Express 2.0 x1, and a legacy PCI. Like with the A85W, all eight SATA 6 Gb/s ports from the FCH are wired as internal ports. DVI, D-Sub, and HDMI handle display outputs. A 6-channel variation of the Hi-Fi audio, gigabit Ethernet, and four USB 3.0 ports make for the rest of it.

    The three will feature in Biostar's first wave of socket FM2 motherboards.

    Oh don't you turn black and blue too, Biostar!

    They are black and blue from getting their butts whooped by Intel.....:toast:

    Heh remember that board a few years back with a vacuum tube for analog audio?

    Seems like FM2 will be good performance.

    It would be nice to have Atom/Fusion powered nettop with max capable sound output system and quality. A sort of box dedicated for movies and music. A PC that you'd easily stick in a living room replacing DVD players and so on.

    It was one of those makers that start with an A (Abit ?) ... It was a preamplifier tube, totally unsuitable for low voltage operation. Its inclusion in the signal path meant nothing but a sh!tload of nonlinearity )= distortion) added to the signal but I guess some idiots bought into it nevertheless. There is absolutely no reason to get your sound mangled THAT MUCH, even if you're looking for "tube sound".

    On-topic: these boards look fugly (visually) - who came up with this braindead balck on black color scheme ?

    Technically they seem awesome but I really cannot get myself to deliberately spend money on a board that will cause me problems when working with it ... as if things weren't bad enough whenever I have to work on something with a torchlight in one hand, screwdriver in the other and two more hands needed to hold/pull/plug whatever bits that Im working on). Not with every other manufacturer coming out with their own version ... hopefully somebody will use one of those easyly distinguishable color schemes such as Gigabyte's blue/white or something along these lines (why not go red/white for AMD, blue/white for Intel ?).

    Probably some guy that saw Foxconns red/black mobos (and after that eVGA/ASUS) and said to himself, they are red, we will be blue..

    Or something like that. I have nothing against that, its still better than mobos which have each PCI-E in different color, brown PCB and 2 colors in ram slots. :D

    Tho bit more of "pure black" mobos wouldnt hurt, shame that black PCB is quite expensive.

    this board seems really overkill, which leads me to believe that am4 will not be, if they can actually make FM2 take piledriver all the way to top end octocores, im guessing that the high end models wont come with onboard graphics, 8 pin eps even...this confuses me a little
