What are the benefits of dual channel for computers, and what are the benefits of forming dual chann

Dual-channel technology.

Speaking of dual-channel technology, let's first explain the dual-channel technology. The so-called dual-channel DDR, in simple terms, means that the chipset can address and read data on two different data lanes separately. These two memory channels working independently of each other are attached to two memory controllers that work independently in parallel with a bit width of 64-bit, so that ordinary DDR memory can reach a bit width of 128-bit, and if it is DDR333, the dual-channel technology can make it achieve the effect of DDR667, and the memory bandwidth is doubled.

In short, dual-channel technology is a technology related to the motherboard chipset, independent of the memory itself, as long as the manufacturer integrates two memory controllers inside the chip, it can form a dual-channel DDR system. Motherboard manufacturers only need to divide DIMMs into Channel 1 and Channel 2 according to memory channels, and users also need to insert memory in pairs, just like RDRAM. If only a single memory is inserted, only one of the two memory controllers will work, and there will be no dual-channel effect.

Your idea is completely feasible for your problem, but it should be noted that the memory model and particle number are the same. It's best to be the same as the original two, so that stability can be guaranteed.

Intel motherboards have about 10% more dual channels, mainly focusing on memory bandwidth and memory integer floating-point operations; AMD is only around 5% because its CPU itself has an integrated memory controller and is not that sensitive to memory bandwidth.

It is equivalent to doubling the external frequency, that is, doubling the speed!

Try to dual-channel, the more you can 2 memory.

Dual theoretical channels, i.e., two memory controllers are designed at the chip level at the North Bridge, and the two memory controllers can work independently of each other, and each controller controls one memory channel. In these two memory, the CPU can address and read data separately, thus theoretically doubling the bandwidth of the memory and doubling the speed of data access. The benefits are:

1. An ordinary single-channel memory system has a 64-bit memory controller, while a dual-channel memory system has two 64-bit memory controllers, with a memory bit width of 128 bits in dual-channel mode, thus doubling the memory bandwidth in the rubber core scattering theory.

2. The dual-channel system contains two independent and complementary intelligent memory controllers, theoretically speaking, both memory controllers can operate at the same time with zero delay between each other.

3. The functions of the two dual-channel memory controllers are exactly the same, and the timing parameters of the two controllers can be programmed separately. This flexibility allows users to use two memory modules with different configurations, capacities, and speeds. Liang.

No setup is required for memory dual channel.

What are the benefits of dual-channel memory.

1. It can bring 2 times the memory bandwidth, so that those software that must exchange memory data frequently can get greater benefits, such as: Spec Viewperf, 3DMAX, IBM Data Explorer, Lightscape, etc.

2. When the onboard graphics card shares memory, the high memory bandwidth brought by dual-channel technology can help the graphics card get a smoother speed in the game, taking 3DMark2001SE as an example, the gap in its score can be widened to 15-40%.

The 2 memory slots are preferentially plugged into slot 2.

The memory slot is in order of priority, the manufacturer will divide the memory module slot from the distance from the CPU from near to far in this order, where 1 and 2 are one channel, 3 and 4 are another channel, so that a dual channel is formed, when using the memory slot, 1 and 2 are preferred, and then 3 and 4 are used, and the specific use depends on the number of memory sticks inserted.

1 is installed in the second slot, 2 is installed in the second and fourth slots, 3 is installed in the second and fourth slots, the third is arbitrary, and 4 is full.

The difference between a single channel and a double channel

Dual-channel memory is more efficient for data transfer than single-channel, especially for computers that don't have a discrete graphics card and use a core graphics card, which supports better graphics performance when using dual-channel.

More channels can provide more powerful memory performance, improve running smoothness, and the performance of program applications with less memory requirements is not much different, but in some applications that eat more memory, bandwidth and capacity, dual-channel brings improvement is obvious, such as **production, 3D animation rendering, AE special effects, games, etc., and the dual-channel acceleration effect is much faster than that of a single channel
