Technology and components
This chapter details the technology and components available in the system.
Topics:
•DDR4
•USB features
•USB Type-C
•Advantages of DisplayPort over USB Type-C
•HDMI 2.0
DDR4
DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows
up to 512 GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM. DDR4 synchronous dynamic random-access
memory is keyed differently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the
system.
DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4
also supports a new, deep power-down mode that allows the host device to go into standby without needing to refresh its
memory. Deep power-down mode is expected to reduce standby power consumption by 40 to 50 percent.
DDR4 Details
There are subtle differences between DDR3 and DDR4 memory modules, as listed below.
Key notch difference
The key notch on a DDR4 module is in a different location from the key notch on a DDR3 module. Both notches are on the
insertion edge but the notch location on the DDR4 is slightly different, to prevent the module from being installed into an
incompatible board or platform.
Figure 1. Notch difference
Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.
8Technology and components
Figure 2. Thickness difference
Curved edge
DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.
Figure 3. Curved edge
Memory Errors
Memory errors on the system display the new ON-FLASH-FLASH or ON-FLASH-ON failure code. If all memory fails, the LCD
does not turn on. Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on
the bottom of the system or under the keyboard, as in some portable systems.
NOTE: The DDR4 memory is imbedded in board and not a replaceable DIMM as shown and referred.
USB features
Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and
peripheral devices like mice, keyboards, external drivers, and printers.
Table 1. USB evolution
TypeData Transfer RateCategoryIntroduction Year
USB 2.0480 MbpsHigh Speed2000
USB 3.0/USB 3.1 Gen15 GbpsSuperSpeed2010
USB 3.1 Gen 210 GbpsSuperSpeed2013
USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)
For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion
devices sold, and yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands.
The USB 3.0/USB 3.1 Gen 1 finally has the answer to the consumers' demands with a theoretically 10 times faster than its
predecessor. In a nutshell, USB 3.1 Gen 1 features are as follows:
● Higher transfer rates (up to 5 Gbps)
● Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
● New power management features
Technology and components
9
● Full-duplex data transfers and support for new transfer types
● Backward USB 2.0 compatibility
● New connectors and cable
The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.
Speed
Currently, there are 3 speed modes defined by the latest USB 3.0/USB 3.1 Gen 1 specification. They are Super-Speed, Hi-Speed
and Full-Speed. The new SuperSpeed mode has a transfer rate of 4.8 Gbps. While the specification retains Hi-Speed, and FullSpeed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480 Mbps and 12 Mbps
respectively and are kept to maintain backward compatibility.
USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:
● An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).
● USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.0/USB 3.1 Gen 1 adds four more
for two pairs of differential signals (receive and transmit) for a combined total of eight connections in the connectors and
cabling.
● USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a
10-fold increase in theoretical bandwidth.
With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices,
high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever
come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320 Mbps (40 MB/s) — the
actual real-world maximum. Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps. We will likely see a realworld maximum rate of 400MB/s with overheads. At this speed, USB 3.0/USB 3.1 Gen 1 is a 10x improvement over USB 2.0.
Applications
USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience.
Where USB video was barely tolerable previously (both from a maximum resolution, latency, and video compression
perspective), it's easy to imagine that with 5-10 times the bandwidth available, USB video solutions should work that much
better. Single-link DVI requires almost 2Gbps throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its
promised 4.8Gbps speed, the standard will find its way into some products that previously weren't USB territory, like external
RAID storage systems.
Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:
● External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives
● Portable USB 3.0/USB 3.1 Gen 1 Hard Drives
● USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters

Technology and components
● USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers
● USB 3.0/USB 3.1 Gen 1 Solid-state Drives
● USB 3.0/USB 3.1 Gen 1 RAIDs
● Optical Media Drives
● Multimedia Devices
● Networking
● USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs
Compatibility
The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0.
First of all, while USB 3.0/USB 3.1 Gen 1 specifies new physical connections and thus new cables to take advantage of the
higher speed capability of the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0
contacts in the exact same location as before. Five new connections to carry receive and transmitted data independently are
present on USB 3.0/USB 3.1 Gen 1 cables and only come into contact when connected to a proper SuperSpeed USB connection.
USB Type-C
USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standards like USB 3.1
and USB power delivery (USB PD).
Alternate Mode
USB Type-C is a new connector standard that is very small. It is about a third the size of an old USB Type-A plug. This is a
single connector standard that every device should be able to use. USB Type-C ports can support a variety of different
protocols using “alternate modes,” which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types
of connections from that single USB port
USB Power Delivery
The USB PD specification is also closely intertwined with USB Type-C. Currently, smartphones, tablets, and other mobile
devices often use a USB connection to charge. A USB 2.0 connection provides up to 2.5 watts of power — that'll charge your
phone, but that's about it. A laptop might require up to 60 watts, for example. The USB Power Delivery specification ups this
power delivery to 100 watts. It's bi-directional, so a device can either send or receive power. And this power can be transferred
at the same time the device is transmitting data across the connection.
This could spell the end of all those proprietary laptop charging cables, with everything charging via a standard USB connection.
You could charge your laptop from one of those portable battery packs you charge your smartphones and other portable devices
from today. You could plug your laptop into an external display connected to a power cable, and that external display would
charge your laptop as you used it as an external display — all via the one little USB Type-C connection. To use this, the device
and the cable have to support USB Power Delivery. Just having a USB Type-C connection doesn't necessarily mean they do.
USB Type-C and USB 3.1
USB 3.1 is a new USB standard. USB 3's theoretical bandwidth is 5 Gbps same as of USB 3.1 Gen 1, while USB 3.1 Gen 2's
bandwidth is 10 Gbps. That's double the bandwidth, as fast as a first-generation Thunderbolt connector. USB Type-C isn't the
same thing as USB 3.1. USB Type-C is just a connector shape, and the underlying technology could just be USB 2 or USB 3.0. In
fact, Nokia's N1 Android tablet uses a USB Type-C connector, but underneath it's all USB 2.0 — not even USB 3.0. However,
these technologies are closely related.
Advantages of DisplayPort over USB Type-C
● Full DisplayPort audio/video (A/V) performance (up to 4K at 60Hz)
● Reversible plug orientation and cable direction
● Backwards compatibility to VGA, DVI with adaptors
Technology and components
11

HDMI 2.0
This topic explains the HDMI 2.0 and its features along with the advantages.
HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI
provides an interface between any compatible digital audio/video source, such as a DVD player, or A/V receiver and a
compatible digital audio and/or video monitor, such as a digital TV (DTV). The intended applications for HDMI TVs, and DVD
players. The primary advantage is cable reduction and content protection provisions. HDMI supports standard, enhanced, or
high-definition video, plus multichannel digital audio on a single cable.
HDMI 2.0 Features
● HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-
enabled devices without a separate Ethernet cable
● Audio Return Channel - Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround
audio system, eliminating the need for a separate audio cable
● 3D - Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater
applications
● Content Type - Real-time signaling of content types between display and source devices, enabling a TV to optimize picture
settings based on content type
● Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics
● 4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital
Cinema systems used in many commercial movie theaters
● HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up
to 1080p
● Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique
demands of the motoring environment while delivering true HD quality
Advantages of HDMI
● Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
● Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video
formats in a simple, cost-effective manner
● Audio HDMI supports multiple audio formats from standard stereo to multichannel surround sound
● HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple
cables currently used in A/V systems
● HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality
