ASROCK X299 Extreme4 Circuit Analysis Continued




We find a Realtek ALC1220 codec along with a Texas Instruments NE5532 amplifier, and Gold series audio capacitors and physical PCB isolation help to improve overall audio signal quality.




The motherboard uses the Intel i219v PHY to produce a fully functioning 1Gbit NIC. An ASMedia ASM3142 and ASM1543 provide the rear USB 3.1 type-A and type-C ports.





The main SuperIO is the NCT6791D, and a Nuvoton N76E88AT provides RGB LED support.




There are multiple NXP switches on the rear of the rear of the motherboard; each moves x2 PCI-E 3.0. Although the slot bandwidth is pretty much fixed, these are required because the pin outs for the Skylake-X and Kaby Lake-X CPUs differ in regards to the PCI-E lanes.
