Chapter 2 Installation
is is a Micro ATX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Make sure to unplug the power cord before installing or removing the motherboard
components. Failure to do so may cause physical injuries and damages to motherboard
components.
• In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.3 Installing Memory Modules (DIMM)
is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel cong uration , you always need to in stall identical (the same b rand,
speed , size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Du al Channel Memory Technology with only one memory module
installed.
3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 sl ot;
otherwise , this motherboard and DIM M may be damaged..
e DIMM only ts in one correct orientation. It will cause permanent dam age to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

3.3 Enabling USB Ports for Windows® 7 Installation
Intel® Braswell and Skylake has removed their support for the Enhanced Host
Controller Interface (EHCI – USB2.0) and only kept the eXtensible Host Controller
Interface (XHCI – USB3.0). Due to that fact that XHCI is not included in the
Windows 7 inbox drivers, users may nd it dicult to install Windows 7 operating
system because the USB ports on their motherboard won’t work. In order for the
USB ports to function properly, please create a Windows® 7 installation disk with
the Intel® USB 3.0 eXtensible Host Controller (xHCI) drivers packed into the ISO
le.
Requirements
•A Windows® 7 installation disk or USB drive
•USB 3.0 drivers (included in the ASRock Support CD or website)
•A Windows® PC
•Win7 USB Patcher (included in the ASRock Support CD or website)
Scenarios
You have an ODD and PS/2 ports:
If there is an optical disc drive, PS/2 ports and PS/2 Keyboard or mouse on your computer,
you can skip the instructions below and go ahead to install Windows® 7 OS.
You only have an ODD (For Intel Skylake platforms only):
If there is an optical disc drive but no PS/2 ports on your computer, please enable the “PS/2
Simulator” option in UEFI SETUP UTILITY > Advanced > USB Conguration, which
allows the USB port to function as a PS/2 port, and then you can install the Windows® 7
OS. Please set PS/2 Simulator back to disabled aer the installation.
You’ve got nothing:
If you do not have an optical disc drive, please nd another computer and follow the
instructions below to create a new ISO le with the “Win7 USB Patcher”. en use the new
patched Windows® 7 installation USB drive to install Windows® 7 OS.

4.5 OC Tweaker Screen
In the OC Tweaker screen, you can set up overclocking features.
Becau se the UEFI soware is constantly being upd ated, the following UEFI setup screens
and descriptions are for reference purpose only, and they may not ex actly match what you
see on your screen .
CPU Conguration
Intel SpeedStep Technology
Intel SpeedStep technology allows processors to switch between multiple frequen-
cies and voltage points for better power saving and heat dissipation.
Intel Turbo Boost Technology
Intel Turbo Boost Technology enables the processor to run above its base operating
frequency when the operating system requests the highest performance state.
English
Long Duration Power Limit
Congure Package Power Limit 1 in watts. When the limit is exceeded, the CPU
ratio will be lowered aer a period of time. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.

H110M-DGS
Long Duration Maintained
Congure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
Short Duration Power Limit

ratio will be lowered immediately. A lower limit can protect the CPU and save
power, while a higher limit may improve performance.

Primary Timing
CAS# Latency (tCL)
e time between sending a column address to the memory and the beginning of the data
in response.
RAS# to CAS# Delay and Row Precharge (tRCDtRP) O
RAS# to CAS# Delay : e number of clock cycles required between the opening of
a row of memory and accessing columns within it.

precharge command and opening the next row.
RAS# Active Time (tRAS)
e number of clock cycles required between a bank active command and issuing the
precharge command.
English
Page 42

e amount of delay that must elapse aer the completion of a valid write operation,
before an active bank can be precharged.
Refresh Cycle Time (tRFC)
e number of clocks from a Refresh command until the rst Activate command to
the same rank.
RAS to RAS Delay (tRRD)
e number of clocks between two rows activated in dierent banks of the same
rank.
Write to Read Delay (tWTR)
e number of clocks between the last valid write operation and the next read command to
the same interna l bank.
Read to Precharge (tRTP)
e number of clocks that are inserted between a read command to a row pre-
charge command to the same rank.
Four Activate Window (tFAW)
e time window in which four activates are allowed the same rank.
CAS Write Latency (tCWL)
Congure CAS Write Latency.
Third Timing
tREFI
Congure refresh cycles at an average periodic interval.
English
tCKE
Congure the period of time the DDR4 initiates a minimum of one refresh
command internally once it enters Self-Refresh mode.
