I was going to change the memory stick at home, and it turned out to be a computer from 3 years ago

Go to my computer,Right-click,Open properties,See the computer column,There will be a CPU model,If you want to be in the details,Next Windows optimization master,There are specific models and parameters in it,You can also go down CPU-Z,More detailed。

The motherboard 3 years ago should be able to support 2G memory, you have to determine what type of memory it is, whether it is DDR1 or DDR2 (I estimate it is 1st generation).

In fact, if the computer memory is too large, it may not necessarily be very fast, 1G is enough, and now DDR1 single 1G ** is about 340.

Hehe, our machines are about the same.,You're a flash dragon 2200+,Generally, its main version supports up to 1G.,CPU is the bottleneck.,There's no point in adding it to 1G.。 Check the CPU with the software CPU-Z.

The board 3 years ago has long been eliminated, and your board will support DDR1 generation, and the 1G one will be on the line.

The first thing you want to do is know how much RAM your motherboard supports. Bureau, I guess.

Your master generally supports 1G bars. There is also a check CPU sex number, you can go next.

CPU-Z software or Everest computer hardware dedicated to the full inspection software is hard.

comprehensive inspection of pieces. So that you can want to know what you want to know.

Concentrate; It can be added, and the extra time indicates that it is the person who asked the question.

Hello subject, I will divide your question into two parts to answer:

1. How much memory do I upgrade to?

You're now using a combination of 1G+2G (definitely, because there are only two sockets),So upgrade to 4G, that is, 2G+2G or a single 4G,Only 1G more,Upgrading 4G really doesn't make much sense,Another point is that you want to install Win10 64bit whether the memory is 3G or 4G is OK。

2. What is the cost and significance of the upgrade?

Even if it makes little sense to upgrade to 4G, then upgrading to 8G is 4G*2, the cost is about 200-300 yuan, and it doesn't make much sense to cooperate with your old Core T series or P series processor (P series performance is weak, although T series is close to i3 or i5 generation, but power consumption and heat are large), and when you upgrade this computer and don't want to use it, it's a bunch of scrap iron, and someone may want to give it away (don't be angry).

3. Personal advice.

Don't rise, don't rise, don't rise! No matter how good the ThinkPad pedigree is, no matter how good the quality is, the T400 is really too old, I don't want to buy a new one, it's not better to spend a few hundred dollars more to buy one that can fight for several more years, such as X230, X240....Regarding the configuration, you can take a look at my answer "How to choose a laptop for office", I hope it will be useful to you!

You can consider installing an 8GB memory module (provided that the maximum memory capacity supported by the motherboard is sufficient), and then install a Win10 64-bit system. However, it is recommended to install win7 64-bit system, which is more compatible and stable.

It doesn't feel like it's necessary, this computer configuration is too old. It's like a barrel, your memory is high, and your CPU and graphics card can't keep up. Especially MATLAB is very CPU-hungry, and your old computer can't keep up.

I don't understand very much, but it is recommended that you check the information first, the memory module on the market at present, is it compatible with your motherboard, if you can, the old computer is theoretically in fact4G and 8G The effect should be the same, if 4G and 8G are different by dozens of yuan, you can directly use 8G

It is recommended to replace it with 8G RAM, and replace the hard disk with an SSD, which is a significant speed increase.

It's up to you to see how you run this morning.

1.First of all, the data in the "memory module" will be cleared every time the computer is shut down, the function of the memory module is to temporarily store the data during the program running, and your data will not be lost if you change the memory module.

2.The floor in the game is blue, it's not that the game is incompatible, it's not that your memory is too small, but your graphics card configuration is not enough, generally the computer in this situation is not equipped with a discrete graphics card, your graphics card should be integrated, you should not have a discrete graphics card.

3.If you have a discrete graphics card, it may be that the video memory is not enough, resulting in incomplete screen loading.

Replacing a memory module does not claim to be a loss of hard drive data. Configure the old CPU of D PentiumNot an issue that affects this game. Memory for gaming, increasing to 4G is a good thing. Don't know what the graphics card is?
