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

dierently 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 dierences between DDR3 and DDR4 memory modules, as listed below.

Key notch dierence

The key notch on a DDR4 module is in a dierent 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 dierent, to prevent the module from being installed into an incompatible board or platform.

Figure 1. Notch dierence

Increased thickness

DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.

8 Technology and components

Figure 2. Thickness dierence

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.

USB features

Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplied the connection between host computers and peripheral

devices like mice, keyboards, external drivers, and printers.

Let's take a quick look on the USB evolution referencing to the table below.

Table 1. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 2.0 480 Mbps High Speed 2000

USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010

USB 3.1 Gen 2 10 Gbps Super Speed 2013

USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)

For years, the USB 2.0 has been rmly 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

Technology and components 9

nally 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

• 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 dened by the latest USB 3.0/USB 3.1 Gen 1 specication. They are Super-Speed, Hi-Speed and Full-

Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode,

commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps 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 dierential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs

of dierential 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-denition 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 320Mbps (40MB/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 real-world 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.

10 Technology and components

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 nd 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

• 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 species 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.

Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which

continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.

Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service

Pack or update. It is not out of the question to think that following a successful release of USB 3.0/USB 3.1 Gen 1 support in Windows 7,

SuperSpeed support would trickle down to Vista. Microsoft has conrmed this by stating that most of their partners share the opinion that

Vista should also support USB 3.0/USB 3.1 Gen 1.

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 dierent 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

Technology and components 11

USB Power Delivery

The USB PD specication 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 specication 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 rst-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

• SuperSpeed USB (USB 3.1) data

• Supports HDMI 2.0a and is backwards compatible with previous versions

HDMI 2.0

This topic explains the HDMI 2.0 and its features along with the advantages.

HDMI (High-Denition 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-denition 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 - Denes 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

12 Technology and components

•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-eective 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

BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device

groups allowing you to:

• Run tests automatically or in an interactive mode

• Repeat tests

• Display or save test results

• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)

• View status messages that inform you if tests are completed successfully

• View error messages that inform you of problems encountered during testing

CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid

results or error messages.

NOTE: Some tests for specic devices require user interaction. Always ensure that you are present at the computer terminal
