Review of Gigabyte X79-UD7 Intel X79 Express chipset Sandy Bridge-E mainboard

Introduction to Gigabyte X79-UD7
Bluetooth 22 Nov 2011

Last week, Intel launches it’s new series of processors based on the LGA 2011 Socket type. WE have already previewed the performance on launch date last week. Today, we will take at the the Gigabyte X79-UD7 motherboard. This new board features some interesting features that were never seen before on previous generation boards.

The X79-UD7 is based on Intel X79 Express chipset. It supports the Intel® Core™ i7 processors in the LGA2011 package. It has 4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory. It employs a 4 channel memory architecture that supports DDR3 2133/1866/1600/1333/1066 MHz memory modules (DDR3-2400 is possible with OC). It supports non-ECC and XMP memory modules.

The board consists of 2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2); 2 x PCI Express x16 slot, running at x8 (PCIEX8_1, PCIEX8_2)
* The PCIEX8_2 slot shares bandwidth with the PCIEX16_2 slot. When the PCIEX8_2 slot is populated, the PCIEX16_2 slot will operate at up to x8 mode.
(All PCI Express x16 slots conform to PCI Express 3.0 standard.). There are 3 x PCI Express x1 slots (All PCI Express x1 slots conform to PCI Express 2.0 standard.)

The board support 4-Way/3-Way/2-Way AMD CrossFireX™/NVIDIA SLI technology and the PCIEX16 slots operate at up to x8 mode when 4-Way/3-Way AMD CrossFireX™/NVIDIA SLI is enabled.

In terms of expandability, the board has 2 x SATA 6Gb/s connectors (SATA3 0/1) supporting up to 2 SATA 6Gb/s devices; 4 x SATA 3Gb/s connectors (SATA2 2/3/4/5) supporting up to 4 SATA 3Gb/s devices which support for RAID 0, RAID 1, RAID 5, and RAID 10. In addition, there are 2 x Marvell 88SE9172 chips that supports 4 x SATA 6Gb/s connectors (GSATA3 6/7/8/9) supporting up to 4 SATA 6Gb/s devices.

The Intel X79 Express chipset also support Up to 14 USB 2.0/1.1 ports (8 ports on the back panel, 6 ports available through the internal USB headers). There are 2 x Fresco FL1009 chips which supports Up to 4 USB 3.0/2.0 ports (2 ports on the back panel, 2 ports available through the internal USB header).

The audio on board is based on the Realtek ALC898 codec HDA and supports 2/4/5.1/7.1-channel, Dolby® Home Theater, S/PDIF Out. There is also a Intel GbE LAN (10/100/1000 Mbit) network port on board.

In addition, this new board features GIGABYTE 3D Power (patent pending)

GIGABYTE X79 series motherboards are the first to take advantage of the exclusive GIGABYTE 3D Power, an all new hardware and software-based Digital Power Engine for both the PWM and Memory that delivers unprecedented power delivery control.

All New Digital Power Control for the CPU and Memory
Utilizing a brand new Digital PWM controller, GIGABYTE’s 3D Power features precise Auto Voltage Compensation to deliver a steady flow of power to the CPU and memory no matter the loading. This all new, all digital power system provides enthusiast users with exceptional control over the overclocking potential of their GIGABYTE X79 motherboard.
GIGABYTE is the first in the industry to utilize digital memory controllers for not only the Memory, but VTT and VSA, for real-time monitoring and adjusting. Digital memory control allows users to monitor and record DDR power and current in real-time while gaming, overclocking or at idle. Users can also set OVP (Over Voltage Protection) to safeguard your memory, adjust memory Load-line Calibration to fix memory vdrooping for a quicker response time and adjust memory PWM frequency on-the-fly.

GIGABYTE 3D Power(patent pending) Utility
Users can now enjoy a fully interactive 3D utility that facilitates adjustment of the 3 dimensions that control the power delivery to your CPU and Memory: Voltage, Phase and Frequency. These parameters are crucial to how the digital PWM supplies power to critical areas of the motherboard and can help users quickly obtain the highest, most stable overclock.
3D Power: Voltage Control
Voltage parameters can be modified within 3D Power, including load line calibration the of CPU. By adjusting load line calibration, Vdrooping can be avoided, maintaining optimal voltages levels despite increasing current levels. OVP (over voltage protection) can also be adjusted to change default protection range of the CPU, memory controller, VTT and system memory.
3D Power: Phase Control
Users can calibrate OCP (Over Current Protection) for the CPU, integrated memory controller and system memory power levels. This allows the Phase control to deliver even more power to the system when needed.
3D Power: Frequency Control
GIGABYTE’s digital PWM allows for adjustable frequency control via the International Rectifier (IR3567) PWM controller. 3D Power frequency control allows users to change the PWM controller frequency so that the CPU VRM can adjust power delivery speeds more quickly. Users can also adjust the PWM spectrum or maximum and minimum overall frequencies.

It also comes bundled with GIGABYTE Bluetooth 4.0 and WiFi Card

With 2 kinds data transfer mode, GIGABYTE Bluetooth 4.0 and WiFi Card providing spec 300 Mbps transfer rates, 802.11n supports the latest WiFi specifications for better signal coverage, and featuring the newest Bluetooth 4.0, you will not suffer from signal loss like before.
