Memory Configurations
The processor supports the following types of memory configurations:
•
Dual Channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual
channel mode is enabled when the installed memory capacities of both SO-DIMM channels are equal. Technology
and device width can vary from one channel to the other but the installed memory capacity for each channel must be
equal. If different speed SO-DIMMs are used between channels, the slowest memory timing will be used.
•
Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world
applications. This mode is used when only a single SO-DIMM is installed or the memory capacities are unequal.
Technology and device width can vary from one channel to the other. If different speed SO-DIMMs are used
between channels, the slowest memory timing will be used.
Graphics
All Xi3 NUCs support graphics through Intel® HD Graphics. The Intel® HD graphics controller features the following:
•
3D Features
− DirectX* 10.1 and OpenGL* 3.0 compliant
− DirectX* 11.0 CS4.0 only
− Shader Model 4.0
•
Video
− High-Definition content at up to 1080p resolution
− Hardware accelerated MPEG-2, VC-1/WMV and H.264/AVC Hi-Definition video formats
− Intel® HD Technology and Advanced Hardware Video Transcoding
− Blu-ray S3D via HDMI 1.4a
− Dynamic Video Memory Technology (DVMT) 5.0 support
− Support of up to 1.7GB Video Memory with 4GB and above system memory configuration
Video Memory Allocation
Intel® Dynamic Memory Technology (DVMT) is a method for dynamically allocating system memory for use as graphics
memory to balance 2D/3D graphics and system performance. If your computer is configured to use DVMT, graphics
memory is allocated based on system requirements and application demands (up to the configured maximum amount).
When memory is no longer needed by an application, the dynamically allocated portion of memory is returned to the
operating system for other uses.
High-bandwidth Digital Content Protection (HDCP)
HDCP is the technology for protecting high definition content against unauthorized copy or interception between a source
(computer, digital set top boxes, etc.) and the sink (panels, monitor, and TVs). The PCH supports HDCP 1.4a for content
protection over wired displays (Mini HDMI and Mini DisplayPort).
High Definition Multimedia Interface (HDMI)
The HDMI port supports standard, enhanced, or high definition video, plus multi-channel digital audio on a single cable.
Each port is compatible with all ATSC and DVB HDTV standards and supports eight full range channels at 24-bit/96 kHz
audio of lossless audio formats such as Dolby* TrueHD or DTS* HD Master Audio. The maximum supported resolution is
1920 x 1200 (WUXGA). The HDMI port is compliant with the HDMI 1.4a specification.
Integrated Audio provided by the HDMI interface includes:
− AC-3 – Dolby* Digital
− Dolby Digital Plus
− DTS-HD*
− Dolby TrueHD, DTS-HD Master Audio*, (Lossless Blu-ray Disc* Audio Format)
− LPCM, 192 kHz/24-bit, 8 channel
USB
The Xi3 NUC supports USB 2.0/3.0 ports. All USBG 2.0/3.0 ports are high-speed, full-speed, and low-speed capable. The
port arrangement is as follows:
•
USB 2.0 ports:
− Two front panel ports are implemented through one dual-port internal header
− Two ports are implemented with vertical back panel connectors
− One port is reserved for the PCI Express Half-Mini Card
− One port is reserved for the PCI Express Full-Mini Card
•
One front panel USB 3.0 port is implemented through an external connector.
