Circuit Analysis Continued




The audio is powered by an ALC1150 which compliments the Intel Azalia processor in the PCH and two Texas Instruments NE5532 are used to amplify the backpanel and front panel audio outputs. Eight Nichicon gold 100uF electrolytic audio capacitors are used for the analog domain and the audio circuitry is isolated to reduce noise. The audio section of the PCB is also isolated so electrical noise doesn't interfere with audio operation.




The X99 OC Formula/3.1 has two wired NICs, one utilizes Intel's i218v and the other is a Qualcomm Atheros A8171 which is basically a Killer e2200 without the special software and the EMI shield.





An ASMedia ASM1142 provides a single USB 3.1 type-C (reversible) port from two PCI-E lanes from the PCH.




Two ASMedia ASM1074s are used, they are USB 3.0 hub controllers which take one USB 3.0 port and expand it into four USB 3.0 ports on the back panel and two internal headers.




Eight ASM1480 PCI-E 3.0 quick switches allocate bandwidth to the yellow 16x PCI-E slots. The Ultra M.2 slot will take its bandwidth from the middle black PCI-E slot through two ASM1480 quick switches which are wired to the CPU's PCI-E 3.0 controller. It can provide up to 32Gb/s bandwidth.




Dual BIOS ROMs are present, each is a 128Mbit part from Winbond. A since ASM1480 switches SATA bandwidth to the 2x PCI-E 2.0 M.2 slot from the S_SATA3_3 connector.




A nuvoTon NCT6791D provides SuperIO functionality and the PS/2 port on the backpanel. A secondary eSuperIO(EC) with BIOS, the nuvoTon NCT6683D, is used to control the OC features on the board, and I think it helps control the OC socket features.




To expand the USB 3.1 capabilities of the X99 OC Formula/3.1 even more, ASRock provides a 2x A-Type USB 3.1 card. The A -Type USB 3.1 connector is backward compatible with USB 3.0, 2.0, and 1.0. This card won't fit in a PCI-E 1x slot and needs a full sized or half sized slot. It uses an ASMedia ASM1142 and a Molex connector to provide the power that is required by USB 3.1. In total the board has three USB 3.1 connectors.
