Introduction to Notebook Memory Upgrade method

How does the notebook memory upgrade work? To improve performance at a lower cost without changing the machine, it is almost the only option to upgrade the accessories. The most perfect book is usually not original, for cost, price, user acceptance factors such as considerations, manufacturers usually do not put a notebook all upgrade to sell, unless the customer is customized. Of course, the notebook design strange, although the following examples have tried to choose the common form, but the actual operation, or hope we can be flexible according to the actual situation, do not stick to the rut. The following are some of the things you need to be aware of when upgrading:

　　Notebook Upgrade Common Sense

First of all, notebooks are actually not flexible desktops, because the primary goal of notebook design is to be portable, not upgradeable, for example, desktop upgrades for video cards and sound cards are commonplace, but in notebooks, only a handful of models can replace the graphics cards, these graphics modules are not universal, even if this very few models of graphics modules, It's not something the average person can buy.

As for sound cards, the only option is an external USB sound card, or an expensive PC Card sound card.

So, what exactly are the parts that can be upgraded in a notebook? The answer is generally memory, hard disk, optical drive and wireless network card, some models can also upgrade Bluetooth, even cpu! As for the number of external USB devices, 1394 devices, PC Card equipment, we will not say, but in the next few articles, we will introduce a few more interesting external equipment, let everyone open their eyes.

　　Upgrade principle

If you have enough money, do not object to you to upgrade all parts, but in the pursuit of cost-effective principle, we should choose to upgrade the most need to upgrade the parts, the money spent on the edge. For different machines and different application environment, there are some differences in the priority order, but generally can be summed up the following laws:

Upgrade memory to 384MB or 512MB: Unless you're still using an old system like WIN98SE, you don't have to follow this principle because WIN98SE is inefficient for memory utilization over 256M, and there's a 256M. But if you are using Win2000 or WinXP, this standard must be elevated to 384M or 512M. 256M can run Win2000 basically, but for Windows xp,256m is just food and clothing, a few more IE browsers will allow your system resources to fall below the poverty line, especially for the installation of SP2 (Service Pack2) of the machine.

512M is a basic requirement for Apple OS X users, because OS X is a fairly memory-eating system, and basically, you should use Windows XP's 150% memory capacity to run OS X smoothly, and if memory is below 256M, even a common simple application may not be fluent.

If you need to engage in a large number of graphics applications, such as Photoshop or large 3D games, I think 512M memory is the most basic requirements, even if the upgrade to a higher 768M or 1GB is not excessive, in short, memory for the notebook is the more and more, for the cost of consideration, I recommend that the laptop running XP system preferably have 512M of RAM, and that the laptop running OS X preferably has 768M. In addition, the current single 1GB memory price is higher than two 512MB memory combined price, the pursuit of cost-effective friends in the upgrade memory can be based on their own books to expand the ability to make a choice.

Notebook memory by interface and size, roughly can be divided into 3 kinds, the first is the most widely used So-dimm, also known as standard memory, the maximum capacity of SDRAM 512M or DDR 1GB, the price is more reasonable, 512M single in more than 300 yuan The second is the Japanese small machine commonly used MICRO-DIMM, also known as small memory, the maximum capacity of SDRAM 256m,ddr 512M, the price is the same capacity So-dimm 150~200%,512m memory is usually more than 350 yuan, and relatively rare on the market. Figure 2 is So-dimm and Micro-dimm contrast, the big one is So-dimm, small is micro-dimm, to here everybody should understand why MICRO-DIMM maximum capacity only to 512MB, because its circuit board area is small, can carry the memory particle is limited.

The last one is dedicated memory, usually it is smaller than the MICRO-DIMM, for those small size machines, such as the classic Sony C1 series first to third generation machines, as well as the most recent vgn-u8c, the price of dedicated memory is not spectrum, because the dedicated, Shing no semicolon, There is no other choice without buying ... Generally speaking, its price is more than MICRO-DIMM still expensive one times, even higher, such as vgb-u8c dedicated 512M memory, asking for more than 700 yuan, compared to a single root 1GB so-dimm.

　　Dedicated memory for SONY u8c

Therefore, unless the poisoning has been deep, otherwise in the selection of machines, should be as far as possible to choose the use of SO-DIMM memory models, so that the future upgrade cost is lower.

Also note that, even if the same as So-dimm or MICRO-DIMM, if the different types of memory, such as SDRAM,DDR,DDR II memory, its interface is slightly different, in fact, the gold finger on the gap is staggered, the pins are also different density.

Here to provide some basis for reference, the general memory annotated with SDRAM, or pc66/pc100/pc133, are SDRAM; usually annotated DDR SDRAM, or DDR 200/266/ddr333/ddr400, or PC 1600/ PC2100/PC2700/PC3200, all of which are DDR memory, or DDR II memory, which is annotated with DDR II or DDR II 400/pc2-4200. If your memory is not marked with anything, then you have to check what chipset the motherboard of your machine uses, and then according to the chipset data, the notebook and the desktop are different, and no notebook will be equipped with two memory slots.
