X299 Gaming M7 ACK Circuit Analysis Continued
MSI is using a novel method of using two Realtek Codecs instead of one and a second amplifier. The method used here ensures that both the rear and front outputs offer 120dB with the integrated headphone amplifier in the ALC1220. Nichicon Gold Series audio capacitors and a fancy PCB divide offer enhancements to the motherboard's audio hardware.
We find a Killer e2500 Gbit NIC for the wired LAN and a Killer Wireless AC 1535 controller for WIFI/BT.
The rear IO panel uses an ASMedia ASM3142 controller and ASM1543 USB 3.1 type-C switch chip. The USB 3.1 internal header also uses an identical ASM3142 and ASM1543 to control the internal type-C header.
ASMedia's ASM1074 takes one USB 3.0 port from the PCH and produces three USB 3.0 ports. One of the USB 3.0 ports uses an ASM1464 USB 3.0 re-driver to ensure USB 3.0 signal strength is strong at the rear of the motherboard.
An ICS6V41742B is used to improve BCLK overclocking margins. The Renesas R5F104 microcontroller provides RGB LED control of the header and built in RGB LEDs on the motherboard.
We get two 128Mbit/16MB BIOS ROMs for the BIOS, and a nuvoTon NCT5605Y GPIO extender enhances fan control. A nuvoTon NCT6795D provides SuperIO functions and offers the PS/2 on the rear IO.
All of those ASMedia ASM1480s switch around PCI-E bandwidth. The LPC812 is an ARM microcontroller, it might be used for the BIOS flash recovery functionality.
