Technical Specifications
Technical Summary
The Gigabyte Z490 UD AC-Y1 motherboard, revision 1.06, is built on the LGA1200 platform with a Z490 PCH and supports DDR4 memory across four dual-channel slots. The system EC/KBC is handled by an IT8686 paired with an IT8795. Audio is provided by a Realtek ALC887 codec, and networking includes a Realtek RTL8118 LAN IC with CNVi wireless support. The BIOS flash is a 256Mbit WSON8 package. Power management includes an ISL69269 charging IC alongside NCP81210, RT8120, RT9018, and IT5702 power ICs. Thermal monitoring is managed by an NCT3933 sensor. The board supports dual BIOS for CS mode and includes a block diagram featuring CPU LGA1200-A/B/C/D variants, DDR4 channel A and B, PCI Express x16 and x4 slots, M.2 x4 and x2 slots, and SATA connectivity.
