Technical Specifications
Technical Summary
The Gigabyte GA-990XA-UD3 revision 1.01 motherboard is built on the AMD AM3/AM3+ platform with an ATI NB GPU and RD780 core graphics architecture. The system is powered by an SB950 southbridge and utilizes an ISL6329+6609 charging IC for core power management. Memory support includes four unbuffered DDRIII DIMM slots. The board features an IT8720 JX EC/KBC controller and a Dual-BIOS SPI flash configuration. Audio is handled by the ALC892R codec, while networking is provided by the RTL8111D and RTL8111E LAN/WiFi ICs. Additional I/O includes a JMB362 card reader, an NEC uPD720200 USB hub controller, and an RTM880N-793 HDMI level shifter. The board number is GA-990XA-UD3 with project code U98094-00, and the document date is April 29, 2011.
