Biostar shows off three Hi-Fi series AMD A85-based Socket FM2 motherboards at Computex, you can view the full-size photos and details about the boards at TechPowerUp.
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.
