Design and features

GIGABYTE G1.Sniper Z97

Model GIGABYTE G1.Sniper Z97 is made on matte black ATX PCB (305 x 233 mm). In general the design of the product has made us a very good impression due to the design of the radiators in cooling system. As for the on-board elements layout, almost all is performed at the highest level. The only nuance is the lack of mounting holes on the edges of the right side, which will require increased care when connecting the main power cable and memory modules.

GIGABYTE G1.Sniper Z97

The reverse side of the printed circuit board is notable for the presence of the standard base plate of CPU socket, as well as plastic clips of the radiator on elements of the power subsystem. In turn, the chipset radiator is fixed with screws.

GIGABYTE G1.Sniper Z97

At the bottom of the board there are the following connectors: front panel audio leading-in socket, CMOS reset, two of three sockets for systems fans, COM port, as well as front panel connection module (with color detection to simplify the connection process). Also here are two leading-in sockets for activation USB 2.0 ports. Total number of USB 2.0 sockets is seven: four are internal and three on the interface panel.

GIGABYTE G1.Sniper Z97

The possibilities of organize a disk subsystem are presented by six SATA 6 Gb/s ports arranged parallel to plate surface. There is a support RAID 0, RAID 1, RAID 5 and RAID 10. Operation of all interfaces is provided by Intel Z97 chipset.

GIGABYTE G1.Sniper Z97

The system board has two DIMM-slots for memory modules of DDR3 standard. RAM can operate in dual channel mode. To implement the plates must be installed either in the first and third or second and fourth slots. Modules operating at frequencies from 800 to 1600 MHz in the nominal mode and up to 3000 MHz in overclocking mode are supported. Maximum memory capacity can reach 32 GB, which is sufficient for almost all tasks.

Leading-in socket on a remote panel with USB 3.0 ports is also located on the right side of the PCB. Total number of USB 3.0 ports is six: two internal and four on the interface panel. All of them are operated via set of system logic.

GIGABYTE G1.Sniper Z97

Separately, select the top right corner of the PCB. Here are some interesting control elements that will be useful in the case of new item use as the basis for an open bench for overclocking experiments. There are buttons "Power", "Reboot" and “Reset CMOS”, as well as diagnostic LED-indicator.

Cooling system of the product includes three heat sinks: the one is used to provide heat removal from chipset Intel H97 while other two cover CPU power elements. In the process of testing the following temperature indices were fixed:

  • radiator for chipset cooling – 33°C;
  • radiator for cooling of processor elements power – 37.5°C.

The obtained results clearly indicate the good performance of the installed system cooling, indicating about the correct selection of materials and design of radiators.

GIGABYTE G1.Sniper Z97

Processor power supply is performed via 8-phase scheme for computational cores and additional joints. Converter is based on a digital PWM controller ISL9582. The circuitry is made by high quality components such as: solid capacitors and chokes with ferrite core. Basic 24-pin and additional 8-pin connectors are use for power feeding. Also here you can find additional PCI Express socket next to 24-pin power socket. It will be useful for building of strong graphics subsystem made of several graphics cards.

GIGABYTE G1.Sniper Z97

To extend the functionality of GIGABYTE G1.Sniper Z97 user has seven slots:

  1. PCI Express 2.0 x1;
  2. PCI Express 3.0 x16 (mode х16 or х8);
  3. PCI Express 2.0 x1;
  4. PCI Express 2.0 x1;
  5. PCI Express 3.0 x16 (mode х8);
  6. PCI;
  7. PCI.

As you can see, the configuration is the most suitable for the installation of one or two powerful graphics cards. Also officially is declared the support of technologies AMD CrossFireX and NVIDIA SLI. Note in case of connection two graphics cards with three slot cooling systems, you will have one free slot PCI Express 2.0 x1.

GIGABYTE G1.Sniper Z97

If you decided to take advantage of the integrated graphics core, then you have two video outputs: HDMI and DisplayPort. The switching between them is realized by chip PTN3360DBS.

GIGABYTE G1.Sniper Z97

Multi I/O capabilities are based on ITE IT8728F chip which controls the operation of the system fans, PS/2 ports, as well as provides the monitors.

GIGABYTE G1.Sniper Z97

Since the chipset Intel Z97 does not support bus PCI, the functioning of the respective connectors is implemented using a bridge PCIe-PCI based on the controller ITE IT8892E.

GIGABYTE G1.Sniper Z97

To support network connections there is a GB LAN-controller Qualcomm Atheros Killer E2201. It has the set of hardware and software advantages to speed up the processing of gaming network traffic.

GIGABYTE G1.Sniper Z97

The audio subsystem is based on the HDA-codec 5.1-channel sound Creative Sound Core3D. It includes special audio capacitors Bi-Polarized produced by Nichicon and preset amplifier Texas Instruments OPA2134PA. According to the manufacturers' specifications, it has a neutral sounding for all genres of music. There is also the possibility of easy replacement to the other, which has a more narrow focus on a particular genre of music. Note the presence of the protective gold-plated housing for shielding audio codec, use of gold-plated audio connectors on the interface panel and the ability to control the sound power with two on-board switches (force 2.5 and 6 times).

Special attention is given to software Creative Sound Blaster SBX Pro Studio to set sound quality to the desired level.

GIGABYTE G1.Sniper Z97

Modding fans will appreciate the presence of the screening area of the PCB with the audio subsystem using the metal strips with LED-backlit.

GIGABYTE G1.Sniper Z97

Interface panel of the model contains the following ports:

  • 1 x HDMI;
  • 1 x DisplayPort;
  • 1 x LAN (RJ45);
  • 4 x USB 3.0;
  • 3 x USB 2.0;
  • 1 x PS / 2 (mouse or keyboard);
  • 1 x Optical S/PDIF out;
  • 1 x coaxial S/PDIF out;
  • 5 x audio jacks.

We note a very successful arrangement of the interface board, which includes not only more than enough USB ports, but two advanced digital video output, as well as opportunities to connect speaker system. Note a specific USB 2.0 port, which is designed to connect an external sound card through the implementation of technology GIGABYTE USB DAC-UP.

GIGABYTE G1.Sniper Z97

The possibility of organizing the cooling system inside the case of GIGABYTE G1.Sniper Z97 is quite standard. There are four 4-pin fan connectors, one of which is used for the cooling system of CPU, while the other three are designed for system fans.


GIGABYTE G1.Sniper Z97

The motherboard is equipped with modern UEFI firmware based on microcode AMI with the ability to operate in four modes: “Smart Tweak HD” (resolution 1280), “Smart Tweak” (resolution 1024 without the display of CPU state, memory and system sensors), “Classic” (classical BIOS) and “StartUp” (mode of initial settings of BIOS).

GIGABYTE G1.Sniper Z97

As you may have noticed, during operation in the mode “Smart Tweak HD” there is no a separate section responsible for the monitoring of voltages and temperatures on the main components, as all the required data is displayed directly on the side panels. Here you can monitor the temperature of the processor and the fan speed; monitor the voltage on the modules of RAM, processor and on the lines of +12 V, +5 V and +3.3 V, as well as a number of other important parameters. Also note that not all items available in the mode “Classic” are in “Smart Tweak HD”.

GIGABYTE G1.Sniper Z97

All settings related to key elements of the system are grouped in the respective tabs.

GIGABYTE G1.Sniper Z97

Using “Frequency” tab you can choose one of six types of automatic optimization of system parameters.

GIGABYTE G1.Sniper Z97

Frequency multiplier allows to set module connection speed within 800-2933MHz. Memory frequency more than 2933 MHz can be run only with the appropriate memory profile.
