Analysis: 2gb And 1gb Memory, How Trade-offs? -2gb, 1gb, Memory-it Industry - Gifts& Health Care

For Memory Firms, in 2007 was undoubtedly a nightmare! Mainstream Memory Chip The

average selling price fell nearly 80% in the fourth quarter alone, the price fell more than 4 percent. Caused a sharp decline in the price is nothing less than oversupply, which led to excess supply and demand factors, including the industry's increased memory capacity, increase production yields, and some manufacturers decided to go to NAND flash memory chip production. Although the price has dropped, but the user has created more problems. I recently found that users of the Internet often is a single 2GB memory, two 1GB memory good or better? Here the writer's two ways to talk about this issue.

Can set up two dual-channel memory mode

price: First, we start with an analysis from the price. Kingston memory take an example, the current market price 1GBDDR2-667 memory, 139 yuan to buy two of the dual channel memory set the price of 278 yuan; now single 2GBDDR2-667 memory, the price of 305 yuan, the price difference is 27 element. From the price analysis, buying a single 2GB and 1GB of spending two basic balance. The KINGMAX brand of memory such as a single and two 1GB 2GB gap between the two is only 10 yuan, comprehensive specifications for the purchase of any of these are feasible.

performance: General performance on memory Test Essential is to see its overclocking ability, and this target is almost certain that a good or bad memory products. In addition, the memory frequency, delay, voltage, read the copy copy, also were compared before and after the memory overclocking project. With EVEREST Software Can test the rated frequency of bandwidth; with MEMTEST software to test the stability of the rated frequency, and so on. For the S & P General Households, the majority of purchases are not used to overclocking memory products, in line with just enough stable first principle, it should concern the work is good or bad memory, diminished or not, the particle model, PCB Layers, cheat technology and so on.

Dual channel memory diagram It is now most concerned about is that in the choice of two 1GB memory, dual channel mode set to choose a single difference between the performance of 2GB, then what is the first to know about dual-channel technology. The so-called dual-channel technology, that is, Motherboard The North Bridge chip (or CPU Internal) integration of two separate memory Controller . Insert the two memory at the right after the CPU can provide twice the memory bandwidth. Which is double the memory bandwidth bottleneck in the whole state of any computer can be achieved, that is able to fully use the CPU to a dual-channel data throughput caused by, or high is a waste of bandwidth. The real application testing, with 128bit memory access system using 64bit memory access performance than the system performance of 3% to 5% higher than the maximum available 12% to 15% performance increase, and these enhance the application in almost daily is the feeling out. Unless it is to run some very large memory bandwidth occupied by the software or games to reflect the value of dual-channel.

Sum up, I think the premise of flat purchase price of a single 2GB memory has an advantage, while the motherboard memory slot limited users to select a single 2GB memory. The reason is: Vista Operating system Is ready to go, and can support 4GB of memory VistaSP1 to the upcoming versions, it is also a 4GB capacity to lay the foundation for future upgrades.
