FLEXIBILITY
Mục Lục
Comprehensive controls form the foundation of the ASUS Prime
series. The Prime B660 motherboard packs flexible tools to tune
every aspect of your system, enabling performance tweaks to
perfectly match the way you work to maximize productivity.
Intelligent Control
All-Around Energy Efficiency
The Energy Processing Unit (EPU) automatically
optimizes power consumption and maximizes energy
savings with Away mode — a smart setting that creates
an extreme energy-saving scenario by shutting down
unused I/O controllers.
Flexible Air- and Liquid-Cooling Controls
ASUS Fan Xpert software provides comprehensive control
over fan. There’s an Extreme Quiet mode that reduces
fan speeds to below the default minimum to keep your
system whisper-quiet when performing light tasks. Fan
can also be controlled via the UEFI BIOS.
Precise Digital Power Control
The Digi+ voltage-regulator module (VRM) delivers
real-time control over voltage droop, automatically
switching frequency and power-efficiency settings. It
also allows you to fine-tune your CPU for ultimate
stability and performance.
UEFI BIOS
The renowned ASUS UEFI BIOS provides everything you need to
configure, tweak and tune your system. It offers intelligently
simplified options for PC DIY beginners, as well as
comprehensive features for seasoned veterans.
Advanced Tuning for Serious Tweakers
An intuitive Advanced mode offered via the UEFI lets you
take complete control. A built-in search feature makes it
easy to find options, and various advanced functions let you
intelligently make nuanced adjustments so you can dial in
performance just the way you want.
Search Function
Quickly and easily find the option or setting you need.
ASUS User Profile
Port configuration settings between different BIOS
versions or share them with friends.
Quick and Simple Setup
EZ mode displays vital settings and stats and also offers
guided wizards, drag-and-drop functionality, and one-click
application of important settings — all to help you get your
rig up and running in no time.
Intuitive Graphical Fan Control
Fine-tune individual fan settings simply by dragging a
curve with the mouse.
EZ XMP
Improve DRAM performance with one click.
COOLING
Prime B660 series are engineered with multiple onboard heatsinks
and an array of hybrid fan headers to ensure your rig stays cool
and stable under intense workloads.
Heatsinks
VRM Heatsink and Thermal Pad
VRM heatsink and thermal pad improve heat transfer from
the MOSFETs and chokes for better cooling performance.
Cooler by Design
Prime B660 series feature comprehensive cooling controls that
are configurable via Fan Xpert software or via the UEFI BIOS.
Multiple Temperature Sources
Each header can dynamically reference three thermal
sensors. Fan Xpert allows you to map the temperature of
supported ASUS graphics cards to optimize cooling for GPU-
and CPU-intensive tasks.
4-Pin PWM/DC Fan
The chassis fan header supports auto-detection of PWM or
DC fans.
PERFORMANCE
Prime B660 series are built to handle the additional cores and
increased bandwidth of 13th & 12th Generation
Intel® processors. ASUS B660
motherboards provide all the fundamentals to boost daily
productivity, so your system will be ready for action with
stable power, intuitive cooling and flexible transfer options.
Power Design
Stable power is essential to extract every last bit of performance
out of 13th & 12th Generation Intel processors.
Prime B660M-K D4 is geared to cater to the demands of these
high-core-count CPUs.
ProCool Connectors
Proprietary connectors augment the motherboard’s link
to the PSU with 8 pin connectors that pass 12 volts of
power directly to the processors. Each jack features
solid pins that can handle more current than
hollow-pin connectors.
6+1+1 Power Stages
A VRM with 6+1+1 Power Stages delivers the power and
efficiency that the latest Intel processors demand.
Memory
DDR4 5333(OC)
Improvements to trace routing design provide the
latest Intel processors with enhanced access to memory
bandwidth. ASUS technology carefully maps memory
signal pathways across different PCB layers to reduce
path distance, and it adds shielding zones that
significantly reduce crosstalk.
Storage
Two M.2 slots (up to 64 Gbps)
Prime B660M-K D4 offers a total of two M.2 slots that support
data-transfer speeds of up to 64 Gbps via PCIe®
4.0, enabling quicker boot-up and app load times with OS or
application drives.
* Actual transmission speeds will be lower than the theoretical
maximum speed.
Connectivity
PCIe® 4.0 Slot
Prime B660M-K D4 is designed specifically for 13th & 12th
Generation Intel® CoreTM CPUs and offer PCIe® 4.0 connectivity. The wide bandwidth and superfast
transmission speeds allow you to create feature-rich
builds that can handle high loads effortlessly.
Realtek 1 Gb Ethernet
Realtek 1 Gb Ethernet reduces CPU overhead and offers
exceptionally high TCP and UDP throughput for faster,
smoother data transfer.
Lower CPU workload
High TCP and UDP throughput
CUSTOMIZATION
Prime B660 series add the nuanced details that improve every
experience, from exclusive codecs that provide pristine audio
quality to intuitive RGB lighting controls that let you
customize your system to create a uniquely personal look.
Audio
Combined onboard features deliver elevated audio
Intelligent design and premium hardware create audio
quality unlike anything you’ve ever experienced.
Audio Shielding
Separates analog/digital signal domains,
significantly reducing multi-lateral interference.
Separate Layer for Left and Right Tracks
Ensures minimal crosstalk between audio paths.
Premium Audio Capacitors
Premium parts provide an immersive sound signature,
with exceptional fidelity.
Personalization
Lighting Control
Brighten Up Your Build
With 5050 RGB strips connected to the RGB header, you
can create your own stunning multicolor lighting
displays with static, blinking, fading, and strobing
effects.
* The RGB-strip header supports 5050 RGB LED strips with
a max power rating of 3A (12V). For maximum brightness,
strip length should not exceed 3m.
** RGB LED Strips are sold separately.
Armoury Crate
Armoury Crate is a new software utility designed to give
you centralized control of supported products. From a
single intuitive interface. The software also provides
control of settings for an ever-growing number of ASUS
products, including keyboard and mouse preferences.
Armoury Crate even features dedicated product registration
and news to help you stay in touch with the ASUS
community.
