The memory should be suitable for buying that model and brand

The DDR400 is more expensive than the DDR2 667.

ADATA 1GB DDR400 (Thousands of Purples) 470 ADATA 1GB DDR2 667 (Thousands of Purples) 315 And with the landlord's computer performance, plus a 1G DDR400 memory, it can't run the current mainstream 3D games, so why waste money on the old platform?

This set of configuration can basically play all the current stand-alone large-scale 3D games, not to mention online games.

If you don't play games, consider the DDR400 512M to give several brands

ADATA 512MB DDR400 245Apacer 512MB DDR400 (Classic Series) 200 Transcend 512MB DDR400 213

If you want to play big games, it is recommended that you change to a new computer, because a good computer is about 3000, and you can play basically large games.

I don't think even if you add 1G to that computer, it won't be very useful. There is only waste. I hope you don't get offended.

DDR you don't buy suitable. It's expensive and inappropriate.

It's better to bleed and change the motherboard.

Let's replace it with a new one, DDR memory is now in short supply and not cost-effective.

A memory module is a channel that connects the CPU to other devices, serving as buffering and data exchange. Although the memory capacity is not large, generally only tens of MB to a few GB, the transfer speed is very fast, so that when the CPU needs data, part of the data can be stored in the memory in advance to solve the urgent need of the CPU. Therefore, choosing a good memory module is the most concerned issue for consumers.

So which brand of memory module is better? Below, the world's factory network will announce the list of the most concerned memory module brands for you: 1 Kingston (1987 United States, the world's leading memory manufacturer, top ten memory brands, rated as the most suitable company in the United States to work for) 2 ADATA (Taiwan, 2001, the world's second largest memory market share, ADATA Technology****) 3 Samsung (the world's top 500 enterprises, China's well-known trademark, the top ten memory brands, 1938 South Korea, Samsung Group) 4 Corsair (respected overclocking memory manufacturer, founded in 1994 in the United States, one of the world's largest memory manufacturers) 5 Apacer (1997 Taiwan, the most influential digital storage brand, well-known brand, Apacer Technology****) 6 Hyundai Hynix (Korea's famous professional memory manufacturer, the world's leading memory manufacturer, Hynix Group) 7 Goldbond Geil (founded in 1993 in Hong Kong, headquartered in Taipei, one of the professional memory module manufacturers, Kingbox (Top 10 Memory Brands, Taiwan Brands, Global Professional Leading Brands, Taiwan Black King Kong Technology Co., Ltd.) 9 KingMax (a world-renowned manufacturer of memory and memory cards, Taiwan, 1989, a professional memory manufacturer).

Hope it solves your problem.

The brands are actually pretty much the same, as long as you don't buy fakes.

Mainstream first-line brands are OK, Kingston, ADATA, and Corsair.

Personally recommend ADATA Jinbang Samsung.

Kingston's incoming goods channel does not know the details or don't buy it, the amount of fakes is like the colorful graphics card of the year.

As for the tall ones such as the pirate ship G.I. G.I. have not had the opportunity to see them so far, and there are too few real people on the desktop.

Top 10 Memory Brands1 Kingston Memory (the world's leading memory brand).

2 Hyundai (Hynix) memory (global brand, best-selling brand).

Chenmao (Twinmos) DDR433 memory with CAS of 2, packaged with CSP technology - this one, the CDR433 memory of Qinmao DDR433 memory is controlled at 2 CAS, the burst length is controlled at , and the performance index is good. In addition, the memory is wrapped around a golden memory cover that dissipates heat and shields, and a thermally conductive gasket is filled between the memory particles and the heat sink. **At about 350 yuan, its superness is not ambiguous, and the cost performance is good.

Hyundai Personally, I think that the original Hyundai and Samsung memory are currently the best compatible and stable memory modules, which are much more realistic than many advertising hype memory modules, in addition, Hyundai"Hynix (more technically, Hynix Semiconductor Inc.)）"D43 and other particles are also commonly used in many high-frequency memory chips. At present, the most valuable modern high-frequency strips on the market are Hyundai original DDR500 memory, and the HY5DU568 Kingston in TSOP package.

As the world's largest memory manufacturer, Kingston's memory products have won the hearts of many Chinese consumers with excellent product quality and first-class after-sales service since entering the Chinese market.

However, although Kingston is the world's largest memory manufacturer, the memory particles used in Kingston brand memory products are indeed varied, including Kingston's own particle products, and more memory particles from many manufacturers such as Hynix, Samsung, Nanya, Winbond, Infinoneen, Micron and many others.

Kingston's high-frequency memory has been adopted"hynix"Kingston DDR400 and DDR433-DDR500 memory of D43 chips and WinBond's memory chips belong to the ValueRAM series (economy) and HyperX series, respectively.

22ct-d5 memory chip, its cost performance is very good.

If you have to buy the above brands, you can buy the Corsair, there are 2000, but less, the Corsair has, and now the standard is 1800MHz

Use Kingston's, although Kingston is not high-end, but the compatibility is good, ** is also very close to the people, pay attention to the frequency of DDR2 when replacing it, use GPU-Z to see what your memory frequency is, I don't know what yours is DDR2

800 or 667.

There are few companies that sell well in the market, and the products have developed step by step to the top ten brands, Kingston

ADATA ADATA

Samsung Samsung

Corsair corsair

Apacer: These are excerpts from the top 10 memory (memory module) brands on the brand**Buy and buy, I think it can still reflect everyone's recognition and support for them, if you want to check the top ten brands, you can find it above.

Most of them use ADATA and Kingston's. Stores are also more common in these two types.

I use Kingston's own, I think it's very good, it's fast, it's shockproof, I think it's very good, and it's been used for 3 years, there have been no problems, you can think about it, or you can refer to the top ten brands of memory cards introduced on the Internet, such as SanDisk Sandisk, Sony Sony, ADATA ADATA, Kingmax, Transcend, Apacer and so on are also very good brands, My girlfriend uses SanDisk, which is also very good, you can compare it.

ADATA and Kingston are both good, reasonably priced and durable.

The above brother is doing Jinbang memory! Are you going to go there and fake Kingston now? The fake is the same as the real one**Who sells the fake?

Ha, I used two 1G Apacer Plus 1G Kingston, and it feels okay, there has been no problem with the memory.

The main memory module brands of desktop computers are Critical (Critical ), Shadow Run (Ӣ ), Asgard (ASGARD), Kefu (Kefu ) , Corsair (Corsair), Ruishi (G.QI), Kingtech (G.C.), Kingtech (G.C.), Kingtech Technology Co., Ltd., Tecoxin (Kingston), ADATA Co., Explorer, Samsung Co., Hyundai (Lenovo), HP, Whisk Qi, Jinpeng City, Taipower and Armor.

Among them, Kingston, Shadow and Corsair are at the top of the brand rankings.

A memory module is a part of a computer that can be addressed by the CPU and can be read and written. Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

Memory modules are an essential part of a computer, and the CPU can address the memory through the data bus. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory. Later computers will not have main memory on the motherboard, and the CPU will rely entirely on memory modules.

All content on external memory must pass through memory in order to function.

The first recommendation is Corsair memory.

Second, G.SKILL memory is recommended.

The main model parameters of the memory module:

1 Capacity: 128m 265m 512m 1g 2g 4g (now the mainstream is 2g).

2 Interface types: SD DDR DDR2 DDR3 (now both DDR2 and DDR3).

3. Working frequency:

SD's 66MHz-166MHz

DDR 200--333-400MHz

Both of the above are rare).

DDR2 is 533-667-800-1066MHz (667 and 800 are the most common).

DDR3 is 1066-1333-1800-2000-2133MHz (1333MHz is used more).

Memory brand: 1 Kingston memory.

2 Modern (hynix) memory.

3 ADATA memory.

4 GEIL memory.

5 Samsung memory.

6 Kingmax memory.

6 Kingmax memory.

DDR3 now basically uses three generations of memory, Kingston or Weigang are good more than a hundred.
