8G dual channel is not a dream

Compared to DIY's other product lines, such as CPUs and graphics cards, the memory/hard disk development speed is surprisingly slow. However, they are slow and their value is beyond doubt. Seeing the end of the year is approaching, we will also take stock of the entire memory product line this year.

● Why does memory exist?

When it comes to memory, it is actually very simple to explain. In the earliest 286 era, the prototype of memory was still an integrated mode. It was directly welded on the main board and caused the drawback of being unable to be disassembled and replaced. Therefore, the concept of a memory bank was born.

As for the role of memory, because there is a big contradiction between the speed of the CPU and the read/write speed of the hard disk, the CPU speed is faster and faster, and the speed of the hard disk is limited. In order to alleviate this conflict, we must use memory. In order to make the transfer rate of the hard disk reach the throughput of the CPU data, it is necessary to use the memory as an intermediate expressway, so that the machine performance can be improved and the efficiency can be improved.

● DDR3 era has already approached Kingston Greater China's memory business director Feng Ruojun said, DDR2 memory by the end of this year, the share of shipments will probably drop to about 20%. In view of the whole year, the proportion of shipments is about 40% to 50%. After November this year, basically all mainstream products will be transferred to DDR3.

In fact, the development of DDR3 is also followed by the pace of development of the CPU. DDR3 has a lower operating voltage than DDR2. It drops from 1.8V of DDR2 to 1.5V, better performance and more power saving; it also upgrades from DDR2's 4-bit read-ahead. Pre-read for 8bit. The most important thing is that DDR3 has a higher operating frequency than DDR2. At present, it can reach a maximum speed of 2400Mhz. At present, the fastest speed of DDR2 is only 1066Mhz.

The development of DDR3 In addition to the soaring price of DDR2 memory, the main factor is that the price of motherboards supporting DDR3 memory has been continuously lowered. Today, some low-end motherboards have also given up on DDR2 memory support, and motherboards supporting DDR3 memory are generally around 400 yuan, the price is still very obvious, so now installed users will consider DDR3 platform.

For DDR2's final market share, it is the upgrading of some old users, the upgrading of enterprise users, and so on, so now the major module manufacturers will also transfer most of the production capacity of DDR2 to DDR3 to meet the market demand for DDR3 memory.

As far as technology is concerned, there is not much improvement in the entire memory product line, but the biggest change is the increase in particle processing.

● 2011 will be the general popularity of DDR3 256 * 8 particles In terms of popular, is the memory PCB board above the particle size, each chip is 256MB, then how many can make up how many GB capacity memory. If it is 8, then it is a single-sided 2GB of memory, if it is 16, then it is double-sided 4GB of memory. The previous generation of technology was 128*8 particles, and two-sided can make up 2GB of memory.

What are the benefits of increasing the capacity of a single chip? For example, if 128*8 particles are used, 16 particles of 2 GB of memory need 16 particles, but 256*8 particles are needed, and only 8 of them can be used. The production cost is greatly reduced.

● 2GB DDR3-1333 is also a transitional product due to the improvement of the chip production process, making the maximum capacity of a single memory up to 4GB, and in 2011, the 64-bit operating system will become very important under the promotion of large-capacity memory. A relationship that complements each other. At present, a 2GB DDR3-1333 memory is priced at 145 yuan, while a single 4GB DDR3-1333 memory is priced at 330 yuan. The price gap between the two is gradually shrinking, so in 2011, a single 4GB memory will be It is very popular and will replace the single 2GB memory and become mainstream in the market.

Summary: In 2011, the frequency of memory is still not the main direction. Although it is very popular for enthusiasts, the bandwidth brought by excessively high frequencies is difficult to realize in practical applications. Instead, most mainstream users pay more attention to memory. Price ratio. If memory is still weak in 2011, a single 4GB memory is bound to prevail, and users who build 8GB dual-channel will also be surprised.
