Motherboard Layout

View Full Size

The GIGABYTE Z97X-UD5H motherboard was designed with a matte black PCB and gold coloration on the VRM and chipset heat sinks, common to their channel line for several of the past board revisions. All board components are black colored to blend in with the board's coloration with the exception of the power and reset buttons. GIGABYTE was able to integrate the new features into the board's design without impacting spacing between components, leaving plenty of room with which to work on the board.

The back side of the board has virtually no circuitry or components, minimizing the risk of damaging the board during installation into the case. Further, the area directly behind and around the CPU socket is entirely free of chips or other components, making the installation of the CPU cooler and its backplate that much easier.

GIGABYTE designed the Z97X-UD5H's rear panel with the following ports: a keyboard / mouse PS/2 port, 2 USB 2.0 ports, 2 USB 3.0 ports controlled by the Intel Z97 chipset (located above the HDMI port), 4 USB 3.0 ports controlled by the Intel Z97 chipset controller via a Renesas hub (located below the GigE NIC ports), an Intel GigE NIC port (inside RJ-45 port), a Qualcomm Atheros Killer NIC port (outside RJ-45 port), an HDMI video port, a DVI-I video port, an optical audio port, and 5 analogue audio ports.

The Z97X-UD5H motherboard has a total of seven PCI-Express device ports - three PCI-Express x16 slots, two PCI-Express x1 slots, and two PCI slots. For the PCI-Express x16 slots, the board supports full x16 bandwidth with a single card, x8 bandwidth with cards in the primary and secondary slots with two cards populated, and x8 / x4 / x4 in all PCI-Express x16 slots with three cards populated. There is sufficient space in between all PCI-Express x16 slots to accommodate up to dual slot coolers. Notice that GIGABYTE also designed the PCI-Express port layout so that a PCI-Express x1 slot remains available even with all PCIe x16 slots populated.

Just below the primary PCI-Express x1 slot is the integrated M.2 port. This port supports M.2 type SSDs, supporting drives with up to 10 Gb/s transfer rates. Note that SATA ports 4 and 5 are automatically disabled with an M.2 SSD installed in the board. The CMOS battery is located to the lower left of the primary PCIe x16 slot.

GIGABYTE designed the audio subsystem on a separate PCB to ensure audio clarity and fidelity. The PCB separator line is demarcated by a yellow line on the motherboard, but does not glow when the board is powered. The front panel audio header is located the upper left corner of the audio PCB, to the left of the audio chipset.

Along the outside of the tertiary PCIe x16 slot are the front panel audio header, the S/PDIF output header, a system fan header, a serial port header, and a trusted platform module device header.

To the lower left of the tertiary PCIe x16 slot are the trusted platform module device header, a system fan header, and an on-board USB 2.0 header.

The two on-board USB 2.0 headers, two system fan headers, front panel header, and the CMOS reset jumper (two pin jumper to the lower right of front panel header) are located in the lower left corner of the board.

The Intel Z97 Express chipset is covered by a large, low profile heat sink just below the PCI-Express x16 slots. The heat sink is gold colored with the GIGABYTE corporate logo along the lower portion of the heat sink in black and white.

GIGABYTE integrated a total of six on-board SATA 6 Gb/s ports and one SATA Express 10 Gb/s port located just under the chipset cooler into the board's design. The two gray colored SATA ports on the right of the port block are tied to the Marvel controller, while the black colored ports on the left are tied to the Intel Z97 chipset controller. To the left of the port block is the PCIe power connector port. This port is used to provide extra power to the PCI-Express slots when multiple video cards are seated in the board. You simply plug in a SATA-style power plug from the PSU into the port.

The on-board DDR3 memory slots are located just below the CPU socket in the lower right quadrant of the board. Dual Channel memory mode is enabled by seating memory modules like colored slots with the gray colored slots acting as the primary slot set. The board supports up to 32GB of memory running at a maximum speed of 2933MHz. Note that memory speeds above 1600MHz are considered overclocked speeds and are outside of the official Intel stock memory speed specifications. Just under the memory slots are the Intel Z97 chipset controlled USB 3.0 header, the 2-digit diagnostic LED, and the 24-pin ATX power connector. The diagnostic LED display can be used in conjunction with the table provided in the user manual to identify and troubleshoot board boot-related issues.

To the lower right of the DIMM slots are the voltage measurement points, the Dual BIOS switch (SB), the active BIOS switch (BIOS_SW), and on-board power, reset, and CMOS clear buttons. The voltage measurement points allow for direct board voltage measurement using a volt meter. The active BIOS switch is used to switch between the primary and backup BIOS. With the switch set to the 1 position (default), the main BIOS is active. In the 2 position, the backup BIOS is activated. The Dual BIOS Switch is set to enabled (the 1 position) by default. Dual BIOS is disabled with the switch in the 2 position.

To the upper right of the DIMM slots are two 4-pin CPU fan headers. The primary CPU fan header is colored white. The secondary CPU fan header can be used to attach a pump RPM output cable when using a water cooling system to cool the CPU.

The CPU socket is clear of obstructions with the power circuitry and VRM heat sink surrounding the upper three sides of the socket. The board contains a total of 12 digital power phases to ensure board stability under all operating conditions. Notice that the M.2 slot to the left of the socket is far enough away from the socket so that it will not interfere with CPU cooler mounting.

GIGABYTE provides a single 8-pin ATX12V power connector to provide additional power the CPU, located in the upper right corner of the board.

"For the PCI-Express x16 slots, the board supports full x16 bandwidth with a single card, x8 bandwidth with cards in the primary and secondary slots with two cards populated, and x8 / x8 / x4 in all PCI-Express x16 slots with three cards populated."

If I am reading the specs correctly, it is x8/x4/x4 with three cards rather than x8/x8/x4.

What a strange way to go about it, a better way would be gen 3 x8, gen 3 x8, gen 2 x4 which is what my board does.

I don't know if that is better. I am assuming that socket 1150 boards are limited to one x16 connection to the processor. This gigabyte board connects through a pci-e switch (some plx chip?) such that all three cards are sharing the single x16 link direct to the cpu at gen3 speeds. With the x8/x8/(x4 gen 2) set-up you are describing, the x4 link probably comes from the PCH (southbridge), so this shares bandwidth with every other IO device (SATA, network, usb, etc.) instead of the other video cards. I believe the DMI link from the PCH to the cpu is similar bandwidth to x4, gen 2 pci-e. This is cheaper as it does not require a pci-e switch chip. The performance difference may be minimal since 3-card set-ups do not scale well anyway. Best to just run 2 cards with this board though. I have wondered if it would work to run a pci-e ssd in one of the slots connected to the switch.

You are correct, tri-card mode is x8/x4/x4.  Thank you for pointing that out....

"GIGABYTE designed the Z97X-UD5H's rear panel with the following ports: ... an HDMI video port, a DisplayPort video port, a DVI-I video port..."

The photos do not show a DisplayPort video port.
I do not believe that the GA-Z97X-UDH5 has DisplayPort connectivity onboard.

Fixed.  Thanks for pointing that out...

great review, but i prefer the looks of previsios z87x-ud5(which i have for my g3258)the heatsinks on this one are a bit to much golden yellow, on the old one they are more blacks in there which ads to the visual look a lot, makes it look a loth better in my opinion

Morry,

Thanks for yet another great review! I've a 4770K right in front of me that needs a cheap place to run! Your expertise, and experience it appreciated!!!

By the way, I really want to win that car!!!
