What is Dual Channel RAM?
Dual Channel RAM is a feature on the motherboard that allows increased RAM bandwidth becomes wider (wider). With Dual Channel, then the available bandwidth has doubled compared with the installation of a single-chip RAM (doubling the value of architecture). Use of Dual Channel RAM requires two pieces are identical, and it is being applied to the platform DDR PC3200, PC4200 & PC5300. Formerly known as the Dual Channel RDRAM.
With dual channel, the bandwidth provided by DDR PC3200 able to at 6.4 Gb / s, whereas for single channel only 3.2 Gb / s only.
Dual Channel is a technology on the motherboard chipset-not the RAM. Each of DDR in use can be configured in single mode mapun Dual Channel. Formerly Dual Channel configuration requires two pieces of RAM are identical (in terms of type, capacity, FSB, to the type IC). But at this point there is a technology called Intel Flex Memory Technology in the Intel motherboard platform that allows two types of RAM which are not identical (type must be identical) to be installed in Dual Channel configuration.
SODIMM (Small Outline Dual In-line Memory Module)
SODIMM RAM is the type used in the Notebook. SODIMM interface, technology and specifications about the same as regular RAM, but with a more compact size and small. SODIMM is a term that refers to the name slot of the motherboard where the RAM is installed, whereby if the motherboard of a PC called the regular DIMMs.
Today more and more important role SODIMM Notebook follow the rapid development that is used by the user. Latest technology on DDR & DDR2 SODIMM is the same as PC technology.
RAM Module Categorization
The world's known there are several categories according to type of RAM module manufacturing sebegai follows:
Fig various RAM Module
* Original modules
Original RAM Modules are produced by many leading vendors who also produce IC. Usually always use the IC Major Brand. PCBs are used sometimes with quality, but sometimes the standard (cost issue). Example: original Hynix, Micron original, Samsung original.
* Major Brand modules
Major Brand and diassembly Modules produced by certain manufacturing-order vendors maker. Usually always use the IC Major Brand, and also use high quality PCB. Example: Visipro, Kingston, Mushkin, Buffalo etc.
* OEM modules
Not using IC Major Brand (probably 1st Grade), who sometimes use the PCB quality and sometimes standard. OEM module only gives the brand on them, while the RAM they will be made by other parties. Example: TwinMos, Apacer, V-Gen.
