Dual channel memory technology is actually a memory control and management technology, it depends on the chipset memory controller work, in theory to make two a par 1 time times the bandwidth provided by the memory. It is not a new technology, have long been applied to the server and Workstation systems, just to solve the growing distress of the Apple Macbook Pro 15 Inch mb134*/A Laptop memory bandwidth bottlenecks before it went to the front desk Apple Macbook Pro 15 Inch mb134*/A Laptop Battery technology. A few years ago, Intel Corporation has launched the i820 chipset that supports dual-channel memory transmission technology,Apple Macbook Pro 15 Inch mb134*/A Laptop Battery, which constituted a Gold partner with the RDRAM memory, played by the extraordinary performance makes it into the biggest bright spot in the market, but the defects of high production costs caused by the best game no one played, were finally eliminated by the market. Because Intel has abandoned its support for RDRAM, so the current mainstream chipset dual-channel memory technology refers to dual channel DDR memory technology for mainstream Intel Intel eight hundred and sixty five-eight hundred and seventy fifths series dual channel memory platforms, while the AMD NVIDIA Nforce2 series.

Dual channel memory technology is to resolve the contradiction between CPU bus bandwidth and memory bandwidth of low price, high performance solution. Now the CPU FSB (front-side bus frequencies) higher and higher, Intel Pentium 4, AMD Athlon XP has a much higher memory bandwidth demands. Intel Pentium 4 processor and Northbridge data transfer with QDR (Quad Data Rate, four times the data transmission) technology, the FSB was FSB 4 times. Intel Pentium 4 FSB 400/533/800MHz, respectively, bus bandwidth is 3.2GB/sec,4.2GB/sec and 6.4GB/sec respectively, and DDR 266/DDR 333/DDR 400 memory bandwidth provided by 2.1GB/sec,2.7GB/sec and 3.2GB/sec, respectively. In single-channel memory mode, DDR memory does not provide data needed by the CPU bandwidth thus becoming the performance bottleneck of the system. Dual-channel memory mode, dual channel DDR 266/DDR 333/DDR 400 memory bandwidth provided by 4.2GB/sec,5.4GB/sec and 6.4GB/sec, respectively, can be seen here, enough to meet 800MHz FSB dual channel DDR 400 memory bandwidth requirements of the Pentium 4 processor. AMD Athlon XP platform, its processor and the Northbridge of data transmission technology using DDR (Double Data Rate, doubling the data transmission) technology, FSB was FSB twice times, their demand for memory bandwidth is far lower than Intel’s Pentium 4 platform, FSB 266/333/400MHz, respectively, bus bandwidth is 2.1GB/sec,2.7GB/sec and 3.2GB/sec, respectively, Using the single channel DDR 266/DDR 333/DDR bandwidth of 400 will be able to meet its needs, so using dual-channel DDR memory technology on AMD K7 platforms, not much Apple Macbook Pro 15 Inch ma896rs/A Laptop Battery can be said to be effective, performance improvement is not obvious as in Intel platform, it is most obvious in terms of performance with an integrated graphics chips integrated motherboard.

Launch NVIDIA nForce Chipset is the first chipset DDR memory interface is extended to 128-bit, followed by Intel E7500 chipset server boards use this dual-channel DDR memory technology, SiS and VIA also responded, an active research and development the exponential growth of technology allows DDR memory bandwidth. However, for various reasons,Apple Macbook Pro 15 Inch ma610*D/A Laptop Battery, to achieve this dual-channel DDR (128 bit memory interface in parallel) transfer is by no means easy for the numerous chipset manufacturer. DDR SDRAM and RDRAM memory quite different, which has a high delay characteristics as well as for serial transmission mode, which nature has designed a chipset supports dual-channel RDRAM memory difficulty and costs are not too high. But DDR SDRAM memory is has itself limitations, it itself is low delay characteristics of, used of is side-by-side transmission mode, also has most important of point: Dang DDR SDRAM work frequency above 400MHz Shi, its signal waveform often will appeared distortion problem, these are for design a paragraph support double channel DDR memory system of chipset brings not small of difficulty, chipset of manufacturing cost also will corresponding to increase, these factors are restriction with this items memory control technology of development.

Ordinary single-channel memory system with a 64-bit memory controller, and 2 dual-channel memory system 64-bit memory controller, 128bit of memory in dual-channel mode bits wide, thus in theory 1 time times the memory bandwidth. While the two 64-bit memory bandwidth provided by the system is equivalent to a 128-bit memory bandwidth provided by the system, but their effect is different. Dual-channel system consists of two independent,Apple Macbook Pro 15 Inch ma610*D/A Laptop Battery , complementary smart memory controller and, theoretically, two memory controllers can be operated simultaneously with zero delay between them. For example, two memory controllers, one for a, and the other is b. When controller b is ready for the next time when accessing memory, controller a read/write main memory, and vice versa. The complementarity of the two memory controllers “nature” lets wait time reduction 50%. Two dual channel DDR memory controllers are functionally identical, and both the temporal parameters of the controller are set can be programmed individually. Such flexibility allows users to use two different constructs, DIMM memory capacity, speed, dual channel DDR simply adjusted to minimum standards to achieve 128bit of memory bandwidth, allowing different density/wait-time characteristic of DIMM memory modules can reliably operate together.

Apple Macbook Pro 15 Inch mb134*/A Laptop chipsets support dual channel DDR memory technology, Intel platforms will have Intel’s 865P/865G/865GV/865PE/875P and later nine hundred and fifteen-nine hundred and twenty fifths series; VIA PT880,ATI Radeon 9100 IGP series, of SIIS 655,SIS SIS 655FX VIA and SIS 655TX;AMD platform KT880,NVIDIA nForce2 Ultra 400,nForce2 IGP,nForce2 SPP and later chips.
