I m an ordinary student and I want to buy a memory module, is it appropriate to buy an old memory mo

First of all, I want to tell you that you are now a student and do not have the ability to earn your own money, so if you can save for your family, you can save a little, and after you graduate and go to work, it is not too late to use your own money to buy!

As far as memory is concerned, second-hand things are not necessarily bad! You first have to pay attention to the date of the warranty label on it (that is, what we call fragile sticks), if not, it is very suspicious, most likely JS has seen the warranty period and deliberately tore it up! Anything that doesn't have a label needs to be asked to the owner about the situation!

Another is to look at the chip particles on the memory! Now it's basically hy, or kingstong, so if there are other memory particles that can't be named, basically don't think about it anymore!

A long memory, 256 is around 140, and 512 is around 270!

Since the memory consumption is not very large, it is up to you to decide whether it is old or new.

It's best not to use two different memory sizes together, and it should be noted that the external frequency of the memory, if one is 333, the other is 400, then it will not improve much speed.

Hit so much, hope it helps you!

It's a few dozen dollars short of the new one, so why bother.

How much is the new 512? The boss is only a little more than 300 of the new good ones.

As for the old ones, I don't recommend them.

Of course, the old and new can be used together, and of course the 256+512 ones are OK, but there are always exceptions, such as the motherboard does not support incompatibility, conflicts between memory, and other problems

Yes, if your computer now has 256 RAM. It is recommended to buy a second-hand 256 memory, DDR memory 256 The old one is about 100 enough, and the new one is only more than 100 pieces, and the memory 512 is enough for you, and it doesn't make sense to have more. It's not much faster, because there's no difference between 512 and 1GB of RAM.

256 plus a 512 can be added together. But I advise you to buy a new one, the electronic products are updated quickly, the old ones have fallen behind in all aspects, and they will be incompatible with the motherboard, and they can't be used!

It's too suitable, it's hard to break the memory, it's OK to test it on the spot

Yes, but not many old ones. And most of the second-hand is problematic. It's not much cheaper. Not recommended. Well. That's it.

Bad is likely to be deceived by js.

Polished and repaired for you.

New expensive but with a warranty.

1. Don't blindly chase famous brands, the so-called famous brands must be fake, not to mention that you are a little white, you can't tell the real from the fake. Find a second-tier brand, slightly cheaper than a big brand, but generally there will be no fakes, recommend you a brand, "Jintaike" is now among the best in domestic sales, and now there are no fakes, you can buy with confidence.

What's more, you don't understand computers, and a slow computer doesn't have to be a memory problem. For example, the operating system has been used for a long time and needs to be redone.

If you have a pot friend to help you judge that it is a small memory problem, there are two ways to buy: first, take the host to the computer city to buy, so that you can try to find out if there is a compatibility problem on the spot, and you can also solve some small problems of the system by the way; Second, if you don't want to move it, you will take off the memory module, take your own memory as a reference to buy it in the computer market, and negotiate with the merchant when you buy it, if it is incompatible, it will be replaced, etc.

That's all there is to you, leave it to fate, Amitabhaamen!

And don't, don't blindly bargain with the merchant at a low price or to death, you feel that you have taken advantage of the 10 yuan cheaper, and when you have other or after-sales problems, the merchant will give you a look, who made you talk about the 10 yuan when you were dead.

You'd better take the memory on your machine and buy it so you don't buy it wrong. If you buy memory, you can get a very low ** when you go to the computer city and ask a few more to buy memory.

You first look at how many generations of memory your home computer memory is, and then buy the same.

lz I don't think you really can buy the memory of your machine right now. , Okay, I can't buy it for me.

No matter how big the memory module is, it will have a depreciation problem.

Choice of memory module:

One of the most important parameters is the maximum amount of memory that the CPU and motherboard can support. Some CPUs and motherboards support 32GB of memory, and more than 32GB of memory is wasted.

The second is the overall performance, and the most commonly used configuration today is the combination of i5+1050Ti+8G, which can run any game perfectly in daily use. And if you want to experience a more refined picture, the memory can be upgraded to 16G (8+8).

Then there is our motherboard problem, as mentioned above, the motherboard supports up to 32G memory bank charging, but the card slot also needs to be noted. There are 4 card slots for large boards and 2 for small plates. If you are using a small board and can only install two memory modules, you need to choose whether it is 4+8 or 8+8.

The large board can be loaded with four strips at will, as long as it does not exceed 32g.

Then there's the wholeness, and the purpose of adding the memory module is to make the game more enjoyable and smoother to use. And when the overall fuselage tends to be old and low, no matter how much memory is added, it will not help. For example, i3+GTX430, even if it is increased to 32G memory, the operation is turtle speed.

In the end, playing games depends on the graphics card, and the graphics card can't keep up with the large memory and can't play a real role.

Last but not least, the transfer speed! Many merchants will not tell you how fast the operation is, but will only say that 8G must be fast, not to add 4G. This is not the case.

First of all, let's look at the speed of our own memory modules, if it is DDR4, 2400MHz, then the memory modules you add should be the same speed. Sticks below 2400MHz will slow down the overall speed, and even adding a 16G size won't help. In the same way, if you buy a memory module higher than 2400MHz, the running state will also be lowered to 2400MHz.
