Intel Optane memory

LPDDR3

LPDDR3 (double data rate third generation low voltage) 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.

LPDDR3 needs 20 percent less or just 1.35 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. LPDDR3 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.

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 LPDDR3 memory is imbedded in board and not a replaceable DIMM as shown and referred.

HDMI 1.4- HDMI 2.0

This topic explains the HDMI 1.4/2.0 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.

NOTE: 

The HDMI 1.4 will provide 5.1 channel audio support.

HDMI 1.4- 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
