• Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique demandsof the motoring environment while delivering true HD qualityAdvantages 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 asimple, 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 cablescurrently used in A/V systems• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionalityMemory featuresIn this computer, the memory (RAM) is a part of the system board. This computer supports a minimum of 2 GB and a maximum of 16 GBmemory, with the following features:• 2400 MHz DDR4 for Vostro 3669 systems• 2133 MHz DDR4 for Vostro 3660 systemsNOTE: If this computer is purchased with Intel 6th Generation CPUs or 7th Generation Celeron dual core CPU, the maximumMHz this computer can achieve is 2133, though the memory material used is 2400 MHz.Verifying system memoryWindows 101 Clickthe Windows button and select All Settings > System .2 Under System, click About.Verifying system memory in setup1 Turn on or restart your computer..2 Perform one of the following actions after the Dell logo is displayed:• With keyboard — Tap F2 until the Entering BIOS setup message appears. To enter the Boot selection menu, tap F12.3 On the left pane, select Settings > General > System Information,The memory information is displayed on the right pane.DDR4DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is keyeddifferently 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 alsosupports a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deeppower-down mode is expected to reduce standby power consumption by 40 to 50 percent.Technology and components 33
