ASRock Z390 Taichi (Intel Z390) Motherboard Preview

By: Steven Bassiri | Socket LGA 1150/1151 in Motherboards | Posted: Oct 8, 2018 4:01 pm

Fatal1ty Z390 Taichi Circuit Analysis Continued




The audio solution consists of a Realtek ALC1220 rated up to 120dB and supports an integrated headphone AMP. The Texas Instruments NE5532 amplifier is used to increase audio quality at the internal header, and we find gold capacitors to help improve audio as well.





We get an i219v PHY and an i211AT for dual GBit NIC.




Intel's Wireless AC 3168NGW is used for 1x1 433Mbps WIFI. An ASMedia ASM1061 is used to add two SATA6Gb/s ports to the motherboard.




Here on the right, we have an ASM1074, which takes one USB port and produces four. We also have an ASMedia ASM1562 re-driver for the integrated USB 3.1 in the PCH, it feeds its signal into the ASM1543 on the rear of the board, which is a type-C controller, and then that signal goes to the internal type-C header.




Two PI3EQX in this picture are two port USB 3.1 10Gb/s re-drivers, they supply the four rear type-A USB 3.1 ports. One port is a type-C port, and so we find an ASM1543 for type-C port control.




It looks like ASRock is using ASUS's chip marking machines again for the clock generator. It makes my life easier since I don't have to look it up, but it would be cool to know the model. Here we find the ASMedia ASM1184e hub, it takes one PCI-E port and outputs to the WIFI, the ASMedia SATA controller, and probably one or two of the PCI-E x1 slots.




Because of the increase in fan headers and the added auto-sensing capability, ASRock had to add a second super IO the NCT5567D (commonly used as the main SIO on their NUCs) to help out the NCT6791D main SIO. We also find the Nuvoton RGB LED chip on the right.




Two 128Mbit ROMs are found on the motherboard and provide increased redundancy for BIOS failures, so you are covered while overclocking. We find some quick high-speed switches to move around PCI-E bandwidth between slots as well as between M.2 slots and SATA ports.


We will have the second part of this review when the NDA date is reached.
