Chapter 2 Installation
is is a Mini-ITX 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.

2.1 Installing the CPU
1. Before you insert the 1700-Pin CPU into the socket, please check if the PnP cap
is on the socket, if the CPU surface is unclean, or if there are any bent pins in the
socket. Do not force to insert the CPU into the socket if above situation i s found.
Other wise, the CPU wil l be seriously damaged.
2. Unplug all power c ables before ins talling the CPU.

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 channe l conguration, you always need to install identical (the same
brand, speed, size and chip-ty pe) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one memory
module installed.
3. It is not allowed to in stall a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwi se, this motherboard and DIMM may be damaged .
e DIMM only ts in one correct orientation. It will cause permanent dam age to
the mothe rboard and the DIMM if you force the DIMM into the slot at incorrect
orientation.

(see p.7, No. 16)
CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short the pins on CLRMOS1 for 5 seconds. However, please do not clear the
CMOS right aer you update the BIOS. If you need to clear the CMOS when you
just nish updating the BIOS, you must boot up the system rst, and then shut it
down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed. Please remember toremove the jumper cap aer clearing the CMOS.

CPU Conguration
CPU Turbo Ratio Information
is item allows users to browse the CPU Turbo Ratio information.
CPU Conguration
CPU P-Core Ratio
e CPU speed is determined by the CPU P-Core Ratio multiplied with the BCLK.
Increasing the CPU P-Core Ratio will increase the internal CPU clock speed
without aecting the clock speed of other components.
AVX2 Ratio Oset
AVX2 Ratio Oset species a negative oset from the CPU Ratio for AVX
workloads. AVX is a more stressful workload that lower the AVX ratio to ensure
maximum possible ratio for SSE workloads.
Core Ratio Extension Mode
Enable or disable core ratio above 85 Extension mode.
[Enabled] Max overclocking ratio limit as specied by OCMB 0x1 command is 120
[Disabled] Max overclocking ratio limit as specied by OCMB 0x1 command is 85.
CPU E-Core Ratio
e E-Core speed is determined by the E-Core Ratio multiplied with the BCLK.
Increasing the E-Core Ratio will increase the internal E-Core clock speed without
aecting the clock speed of other components.
Cluster 0 Max Ratio
Override ATOM Core 0 - 3 Maximum OC Ratio, maximum value up to 120.
Cluster 1 Max Ratio
Override ATOM Core 4 - 7 Maximum OC Ratio, maximum value up to 120.
CPU Cache Ratio
e CPU Interna l Bus Speed Ratio. e maximum should be the same as the CPU
Ratio.
H670M-ITX/ax
BCLK Aware Adaptive Voltage
BCLK Aware Adaptive Voltage enable/disable. When enabled, pcode will be aware
of the BCLK frequency when calculating the CPU V/F cur ves. is is ideal for
BCLK OC to avoid high voltage overrides.
Boot Performance Mode
Select the performance state that the BIOS will set before OS hando.
Ring to Core Ratio Oset
Disable Ring to Core Ratio Oset so the ring and core can run at the same fre-
quenc y.
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

implment the Intel ermal Velocity Boost (TVB) feature.
Dual Tau Boost
Enable Dual Tau Boost feature. is is only applicable for CMLS 35W/65W/125W
skus. is item is only supported with processors with Cong TDP support.
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.
Long Duration Maintained
Congure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
English
54
Short Duration Power Limit
Congure Package Power Limit 2 in watts. When the limit is exceeded, the CPU
ratio will be lowered immediately. A lower limit can protect the CPU and save
power, while a higher limit may improve performance.
CPU Core Unlimited Current Limit
To unlock voltage regulator current limit completely, you can set this option to
Enabled.
CPU Core Current Limit
Congure the current limit of the CPU core. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.
GT Unlimited Current Limit
To unlock voltage regulator current limit completely, you can set this option to
H670M-ITX/ax
