I want to change the memory, how much does a mid to high end brand cost, a 1G brand?

Depends on what model of memory you want to support.

It's very difficult.

About 380 pieces, the best brand, Kingston 1G DDR II 667

Kingston 1GB DDR 400 420

Kingston's 1GB DDR2 533 seems to be a rarity on the market.

Kingston 1GB DDR2 667 305Kingston 1GB DDR2 800 490 There are also several brands.

For example, Corsair, AGON, and Black King Kong are also okay.

**As far as the pirate ship is concerned, it is slightly more expensive, and everything else is about the same.

After all, pirates are dedicated to enthusiasts, and the reputation is good, and the quality is quite good.

What model of DDR400? ddr533，667，800？

It's not the same.

Kingston's is not bad.

Nowadays, the mainstream memory is DDR2, and it will take time for DDR3 to become popular.

It is recommended that you use Kingston, Corsair, ADATA and other brands of memory modules.

Their 1g ** is generally.

Kingston 1GB DDR2 667 305

Kingston 1GB DDR2 800 490

ADATA 1GB DDR2 667 (Thousands of Purples) 315 ADATA 1GB DDR2 800 (Red Veyron) 415 and Corsair are also good, ** similar to the above.

A memory module for DDR400 333 266? I suspect it's only sold for a few dozen dollars now.

It depends on the DDR number and the brand.

DDR1 is the most expensive, about 100 yuan.

DDR2 is only sold for about 70 yuan.

Hello, Kingston's memory is good, about 100-200 yuan.

1g/ddr667

140-170 yuan (different brands** are also different).

1g/ddr800

150-190 yuan (different brands** are also different).

1g/ddr400

Around 410 (basically gone).

How much does a typical 1G memory stick cost now?

The new 1G DDRII 800 is 130 yuan for the ordinary brand , and the 160 yuan for the good brand is ......There are more expensive ones; $100 for second-hand.

The new 1G DDR 400 is 240 yuan for the ordinary brand and 280 yuan for the good brand......There are also more expensive ones; Second-hand 160 yuan.

And what kind of brand is suitable for my machine?

What does your computer look like? How do we know?

What model of RAM do you want?

DDRII's 1G 667 800 **130 135 or so (all brands are similar).

The DDR400 1G is a bit more expensive than the 'Hyundai' 1GDR400**185

Kingston, ADATA, and Apacer 1GDDR400 are all around 240.

The above is Beijing's **. I don't know the owner** of the landlord** so I gave the price of Beijing Zhongguancun ** July 23, 2008.

The landlord can go to Zhongguancun to check out the various places**.

About 70 yuan, if you want to buy memory, it is best to take the memory of your machine to the computer city and ask them which one matches, and then say no, you can replace it.

Memory** changes are relatively large, sometimes a day is worse than dozens of dollars, today Kingston DDR2 800 ** is 167 (Shenzhen to get the price), a little higher than a few days ago.

You can check it on the Pacific Net.

Kingston, ADATA, Black Kong, Kingston, we recommend Kingston.

Around 150 yuan.

There are too many fakes in Kingston, and Apacer is recommended.

and kingmax's ...

See if it's DDR1 or DDR2! Generally speaking, DDR1 is more expensive! It should be an old try!

There are fewer productions! One with 512 is about 250! If it's a 1G of DDR2, it's only 100+!

Ay! What a gap!

Now it's about 140-250

I can't see what brand fits, you have to take the machine with you, buy it and plug it in.

It depends on the generation or the 2nd generation, and there are slight differences in the specific ** places, and the 2nd generation is about the early 100s.

DDR2 around 150.

DDR around 250.

You look at the model number of the motherboard of the machine.

Or roughly in configuration.

Dozens, fifty or sixty.

Look at the model number of DDR400 around 200 DDR667 around 150.

Forty or fifty dollars...Is it a TF card?

About 100 is basically fine.

2 generations. Around 180.

Kingston's.

Desktop. DDR2. 1g

Around 120.

DDR3.

1g 100 or so.

Kingston. 1g

Kingston 2G is recommended to buy 2G.

Don't buy a modern one, don't try to be cheap.

Kingston is good, pay attention to anti-counterfeiting, and Kingston's ** has an anti-counterfeiting code.

If you want to overclock, choose the gold overclocking Apacer 1G

If it is compatible, it is good.

Performance is slightly better for Kingston.

Generally seven or eight hundred, and the trustworthy ones seem to have a better reputation, such as Jintaike, Kingston, or Black King Kong.

DDR1 or DDR2?

Kingston has a good reputation, and its compatibility and stability are also outstanding

Check it out. The ** varies from place to place.

Kingston is a little better.

Apacer's memory is still good.

But most of them are now using Goldbond, or Kingston's memory.

DDR1 memory is now more expensive.

DDR2 memory is quite cheap.

If you say the brand, you don't dare to say it.

If you buy a better memory card, you have to buy a better one, otherwise it will affect your mobile phone.

The cheapest 40 pieces are available, I've seen them.

There are also more expensive ones around 80.

Look at yourself.

It's not easy to buy.,It's recommended to buy a 512 to replace it.,Buy a 256 one without accounting.,But in fact, it's more than 100 yuan to change DDR2's 1G.,But if you change it, the main version.,CPU also change.。

Therefore, it is recommended to buy a 256 DDR1 and replace it with the same original.

It is easy to have problems when buying 512, and it is not easy to buy obsolete things with 256, and the sex leave ratio is very low.

There are four performance metrics for memory modules:

1) Storage capacity: that is, the amount of binary information that can be contained in a memory module, such as the storage capacity of the commonly used 168-line memory module is generally 32 megabytes, 64 megabytes and 128 megabytes.

2) Access speed: The minimum time required between two independent access operations, also known as the memory cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.

3) Reliability of memory: The reliability of memory is measured by the mean time between failures, which can be understood as the average time interval between failures.

4) Performance ratio: Performance mainly includes memory capacity, storage cycle and reliability, performance ratio is a comprehensive index, for different memory has different requirements.

Happy New Year!

Go buy DDR's memory module,The specification is DDR400,Don't buy DDR2,It's not compatible,Buy 512M is enough,Nearly 200 pieces,No need to buy 1G。 Kingston and ADATA are two brands that are better and more cost-effective.

Recommendations:1It's best to disassemble the original memory and buy it with the same specifications, don't sell the old memory, you can't sell it for a few dollars, it's not cost-effective. Stay on it, plus 512m, there will be 768m, and the general software can run relatively smoothly.

2.Remember to get a receipt or shipping note after you buy it.

Adding a DDR256 is fine, and any bigger one is wasted because your CPU only.

This generally depends on the motherboard.

But look at you like this. It should be the memory of the DDR generation.

It is recommended that you sell the old strips and rebuy them to see what model it is, or DDR400 or 667, and the basic 1G is almost the same.

Add another 256m 512 is good enough to use, and the memory of your model is estimated to be more expensive because it is an old model.

You still don't need to add memory to an old machine like you, the cost is too high, it is recommended to buy a new computer directly.

Your platform is quite old, and if you only support DDR memory, it will be a little more expensive than the current mainstream DDR2.

1g is around 200.

I don't know what you want for 1g.

Is it DDR or DDR2

DDR3 if you want DDR2

800's. I'll sell it to you.

Lapping is cheap!

It depends on what kind of you want.,Brand,Model,Frequency can affect the memory**,Now the installation (installation of a new machine,Not an upgrade) usually chooses DDR3 memory,Personal recommendation。

Jinbang Technology, especially platinum bars, has good workmanship, good heat dissipation and durability, and the price of Goldbond DDR31333 (platinum bars) ranges from 170-190. Goldbond DDR31600 (platinum bar) prices range from 250-370. As for DDR2, it has now gradually faded out of the market, but it can also be passed for a while.

Jinbang DDR2

The price of 1066 (white gold bars) ranges from 110 to 150. But I personally recommend DDR3 memory (as long as your motherboard supports it), after all, the era of DDR2 is over, and sooner or later it will have to be replaced.

It's DDR2, DDR3, they have different frequencies! DDR2 is generally yes, DDR3 is generally and higher! Now I generally use DDR2, and 1G is about 150 yuan! It depends on what brand!

I don't have a ** in Xiamen.

The average for each region** is:

DDR1190 yuan.

DDR279 yuan.

Generally, the memory is replaced by an old machine-

It is generally DDR1.

Because it has long been discontinued.

So ** high)

DDR2 is enough for general home computers.

The relative latency of DDR is much smaller than DDR2 and more stable, 1GDDR2

800 is now less than 100 yuan.

Look at your configuration memory should be a generation of DDR400, because there is no manufacturer in the world to produce a generation of memory, so the number of circulation is getting smaller and smaller, **It should be around 200-250.

Kingston's good is about 130, and the others are less than 115.

It's cheap, change it, 1g667 is cheaper.

Kingmax 1G DDR2 800 145 yuan.

DDR is backwards compatible, so don't worry about the model, the memory will adjust the frequency by itself.

Apacer, Kingston, ADATA, Kingmax, etc. are all large manufacturers, with excellent quality and after-sales service.

It depends on whether your computer's memory is 1st or 2nd generation.

Different ** is different. The first generation of about 290. The second generation has about 130 memory.

I bought 1G Kingston two months ago is only 120, and the current ** is about 120, Kingston is too fake, it is recommended that you buy Samsung gold bar DDR800 1G is now about 150! However, it depends on whether your motherboard supports DDR800 or not. If you want to add memory, you should pay attention to the motherboard description of the model supported by the memory slot (DDR667 800 or older), and buy one that can adapt to the motherboard.

Your computer can only be equipped with DDR400, and now 1G is about 250 yuan, and the brands are about the same.

Kingston's memory is good, about 130 bars of 1G memory.

It's all up to date there**. It's almost the same to buy according to the ** inside.

Hehe, we bought Kingston's 1g, 130. And this brand is generally added in our class.
