Rampage VI Extreme Circuit Analysis Continued


ASUS's Realtek ALC/S1220 implementation is top notch as it comes upgraded with an ESS Sabre 9018Q2C DAC/AMP with -112dB THD capabilities. We also see switching MOSFETs for impedance sensing, Nichicon Audio capacitors, PCB isolation, as well as dedicated power amplification (found on the back of the PCB), and the audio jacks are illuminated.


An Aquantia AQC107 10Gbit NBase-T NIC is capable of 10G, 5G, 2.5G, 1G, and 100M speeds. The Wireless AD (4.6Gbps)/Wireless AC (1.3Gbps) card is the QCA6174-W0096 from Qualcomm.


An Intel NIC is also present; the i219V is the PHY that compliments the integrated MAC in the PCH and provides a 1Gbit connection. An STM32 microcontroller is found on the motherboard; I believe it's used for the OLED or the addressable RGB LED header.


We find two ASMedia ASM3142 USB 3.1 controllers, and each gets x2 PCI-E 3.0. The type-C port on the rear IO gets an ASMedia ASM1543 type-C switch and CC logic chip.


We also find two ASMedia ASM1074 USB 3.0 hubs. One at the rear provides four USB 3.0 ports and one found near the SATA ports provides bandwidth for the two internal USB 3.0 headers.


We find two identical TPU chips labeled KB3728Q and they provide extra ROG capabilities and even overclocking features. We also find other ROG labeled chips that provide unique features such as Keybot. The motherboard has two physical 16MB/128Mbit BIOS ROMs.


A nuvoton NCT6796D is the SuperIO controller that provides system monitoring and other capabilities such as fan control. The BIOS chip found on the back of the motherboard provides USB BIOS Flashback capabilities.


The Pro Clock II IC is a clock generator used for increasing BCLK overclocking margins. An IDT5V230 is used to enhance PCI-E device support.


A Texas Instruments DS80PCI402 is an 8Gbps per lane 4-lane PCI-E 3.0 repeater, and it's used to improve PCI-E signaling for the U.2 port which switches with the M.2 slot. We find a ton of ASMedia ASm1480 quick switches, almost as many as I found on another 2nd wave X299 motherboard, and they are used to switch all motherboard bandwidth. If we look closely, we can see that the chips above directly move x12 PCI-E 3.0 to the second set of switches, meaning they switch bandwidth two levels down in an orderly fashion (one at x8 and the other at x4).
