Safety Instructions
To reduce the risk of fire, electric shock, and injury, always follow basic
safety precautions.
Remember to remove power from your computer by disconnecting the
AC main source before removing or installing any equipment from/to the
computer chassis.

Preparing the Motherboard
Installing the CPU
Be very careful when handling the CPU. Hold
the processor only by the edges and do not
touch the bottom of the processor.
Use the following procedure to install the CPU
onto the motherboard:
Unhook the socket lever by pushing down and away from the socket.
Pull the socket lever back and the load plate will
automatically lift. There is a protective
socket cover within the CPU socket to
protect the socket when there is no CPU
installed.
Remove the protective socket cover from the
CPU Socket.
Note: After removing the CPU socket cover, it is recommended that you keep it
in case you need to remove the CPU so for any reason you can replace
the cover to avoid damaging the CPU socket pins.

Align the notches in the processor with the
notches on the socket.
Lower the processor straight down into the socket
without tilting or sliding it into the socket.
Note: Make sure the CPU is fully seated and level in
the socket.
Close the load plate over the CPU and press
down while you close and engage the
socket lever.
The CPU installation is complete.
Installing the CPU Fan
There are many different fan types that can be used with this motherboard.
Follow the instruction that came with your fan assembly. Be sure that the fan
orientation is correct for your chassis type and your fan assembly.
Align notches with notches on the CPU

EVGA Z75 Motherboard

Installing System Memory (DIMMs)
Your new motherboard has four 240-pin slots for DDR3 memory. These slots
support 1GB, 2GB and 4GB DDR3 DIMMs. There must be at least one
memory slot populated to ensure normal operation. Use the following the
recommendations for installing memory.
One DIMM: If using 1 DIMM (Single Channel), install into: DIMM slot 2.
Two or Four DIMMs: If using 2 DIMMs (Dual Channel), install into:
DIMM slots 2 and 4. If using 4 DIMMs (Dual Channel), install into:
DIMM slots 1, 2, 3, and 4.
Use the following procedure to install DIMMs. Note that there is only one
gap near the center of the DIMM slot. This slot matches the slot on the
DIMM to ensure the component is installed properly.
1. Unlock a DIMM slot by pressing the module clips outward.
Align the memory module to the DIMM slot, and insert the module vertically
into the DIMM slot. The plastic clips at both sides of the DIMM slot
automatically lock the DIMM into the connector.
Installing the Motherboard
The sequence of installing the motherboard into a system case depends on the
chassis you are using and if you are replacing an existing motherboard or
working with an empty system case. Determine if it would be easier to make all
the connections prior to this step or to secure the motherboard and then make
all the connections. It is normally easier to secure the motherboard first.

Use the following procedure to install the I/O shield and secure the
motherboard into the chassis.
Note: Be sure that the CPU fan assembly has enough clearance for the system
case covers to lock into place and for the expansion cards. Also make sure
the CPU Fan assembly is aligned with the vents on the covers. This will
depend on the system case being used.
Installing the I/O Shield
The motherboard kit comes with an I/O shield that is used to block radio
frequency transmissions, protects internal components from dust and foreign
objects, and promotes correct airflow within the chassis.
Before installing the motherboard, install the I/O shield from the inside of the
chassis. Press the I/O shield into place and make sure it fits securely. If the
I/O shield does not fit into the chassis, you would need to obtain the proper
size from the chassis supplier.
Also Note that for ease of installation you may want to install I/O shield Fan
(optional) before installing into case.

15
Securing the Motherboard into a System Case
Most system cases have a base with mounting studs or spacers to allow the
motherboard to be secured to the chassis and help to prevent short circuits. If
there are studs that do not align with a mounting hole on the motherboard, it is
recommended that you remove that stud to prevent the possibility of a short
circuit. In most cases, it is recommended to secure the motherboard using a
minimum of nine (9) spacers and screws.
1. Carefully place the motherboard onto the stand offs located inside the chassis.
2. Align the mounting holes with the stand offs.
3. Align the connectors to the I/O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according to the fan
assembly instruction.
5. Secure the motherboard with a recommended minimum of nine (9) screws.

Connecting Internal Headers
Front Panel Header
The front panel header on this motherboard is one connector used to connect
the following four cables.
(see Table 2 for pin definitions):
PWRLED
Attach the front panel power LED
cable to these two pins of the
connector. The Power LED indicates
the system’s status. When the system is
powered on, the LED will be on.
When the system is turned off, the
LED is off. When the system is in S1,
S3,
S4 status, the LED will blink.
Note: Some system cases do not have all four cables. Be sure to match the
name on the connectors to the corresponding pins.
PWRSW
Attach the power button cable from
the case to these two pins. Pressing
the power button on the front panel
turns the system on and off rather
than using the onboard button.
HD_LED
Attach the hard disk drive indicator
LED cable to these two pins. The
HDD indicator LED indicates the
activity status of the hard disks.
RESET
Attach the Reset switch cable from
the front panel of the case to these
two pins. The system restarts when
the RESET switch is pressed.
