X299-UD4 (Socket 2066) Intel X299 ATX MotherboardThe UD4 represents Gigabyte's upper tier platform for High-End Desktop Processors from the Skylake-X and Kaby Lake-X generations that utilise the X299 chipset and demand a LGA2066 socket. This chipset, codenamed "Lewisburg", is notable for its up to 30 HSIO lanes (High-Speed Input/Output) as well as the maximum usable number of 24 PCIe Express 3.0 lanes. This makes it a true "no compromises" solution that allows multiple internal connectors to be utilised simultaneously.
The Features of the Gigabyte X299 UD4 at a Glance:
- 5× PCIe (3.0) x16 (2× x16 / 1× x8 / 2× x4)
- 2× USB 3.1 (2× Type-A)
- 10× USB 3.0 (6× Type-A / 4× internal) & 4× USB 2.0 (internal)
- 2× M.2 (PCIe 3.0 x4) / 8× SATA 6G
- 8× DIMM-Slots for DDR4-RAM (max. 128 GB with 28 or 44 lane CPU)
- Includes ac-WiFi module and antennae
- RGB-LED lighting
The Gigabyte X299 UD4 in DetailThe Gigabyte X299 UD4 is a premium enthusiast motherboard using the ATX format and is designed for hardware enthusiasts and professionals looking for a X299- & Skylake-X or Kaby-Lake X pairing. The extremely stylish black board comes with five PCIe-x16 slots, of which two are connected to the chipset with a full 16 lanes while the other three are connected electrically by 8 or 4 data lines. This allows the use of a 28 or 44 lane CPU as well as NVIDIA's 3-Way-SLI or AMD's 3-Way- CrossFireX configuration.
Equipped with a total of eight DIMM-slots for DDR4-RAM, a CPU with 28 or 44 data lines can operate all slots in Quad-Channel mode with up to a maximum capacity of 128 GB of memory. A CPU with 16 lanes supports Dual-Channel mode over four slots with a maximum capacity of 64 GB. Officially DDR4 modules can be used at up to 2.666 MHz, and after overclocking even higher clock frequencies are possible.
The board provides extensive connectivity for data storage devices with two M.2-slots for exceptionally fast NVMe-M.2 SSDs as well as eight SATA 6G ports for 3,5" or 2,5" hard drives and SSDs (including RAID support). The M.2 ports are connected to the chipset via four PCIe lanes using the 3.0 standard which enables, in combination with the NVMe protocol, a data transfer rate of almost 4 GB/s. This allows M.2 PCIe SSDs to function up to eight times faster than SATA 6G SSDs! Furthermore the M.2 slots are equipped with thermal guards to allow the heat build-up on the modules to be reduced and prevent lost performance.
External ConnectorsThe I/O bracket of this performance-oriented motherboard comes with various useful ports to make life easier for users. The board comes with four further backwards compatible USB 3.1 ports. Board verfügt über vier weitere, abwärtskompatible USB 3.1 ports. Thanks to the ASMedia 3142 USB 3.1 controller, maximum speeds of up to 16 Gbit/s are reached, three times faster than previous USB 3.0 ports. Of course the board also comes with six USB 3.0 ports for input devices and gaming peripherals.
For unhindered network connectivity the X299 UD4 also comes with a Gigabit LAN port. For quality sound the the Realtek ALC1220 Codec and a total of five gold-plated audio ports are available, supplemented by an optical S/PDIF-Out port. Furthermore a classic PS/2 port for keyboards and mice is provided on the I/O panel.
