Help me see what kind of memory sticks the computer should buy

It is the DDR generation memory, the memory model is DDR266 memory, and now it is difficult to find 266 DDR1 generation memory, which is generally DDR400 memory module.

It is recommended that the landlord sell the current one and buy a new oneG memory module.

DDR-SDRAM Annotations:

Strictly speaking, DDR should be called DDR SDRAM, people are used to calling it DDR, and some beginners often see DDR SDRAM, and think that SDRAM is the abbreviation of Double Data Rate SDRAM, which means Double Rate Synchronous Dynamic Random Access Memory.

The landlord may not know much about hardware.

What we call DDR is DDR generation memory.

Second-generation memory, we all say DDR2

Your machine can only use DDR memory.

There are only three kinds of DDR266 DDR333 DDR400, and now most of them only have DDR400, and the memory of DDR400 may be used on the DDR266 memory machine, and it is a big deal to downgrade to 266 mode to work.

It is the memory of the DDR generation, and some of it is sold now.

Kingston, modern ones are available, but the memory of the generation 1G ** is very high.

It should be around 200 yuan!!

You can buy a 2G Kingston memory module, the larger the memory, the better, but too large memory is expensive, or 2G is more suitable.

05 years of computers. You should buy any brand of DDR-533 and less memory. DDR-400 is recommended

First of all, you have to ensure that you will disassemble, the laptop is not easy to disassemble, especially HP's, the cover is very man, and every time I disassemble it, I will inevitably have a few more screws and nowhere to install it, and secondly, it depends on how many generations your computer is configured, if the configuration of the 2nd generation is installed with the 3rd generation of memory sticks, it is definitely not possible, you have to check it out before buying.

Ordinary laptop memory modules, as long as they are of the same model and have the same slot, are compatible (except for a few exceptions).

1. The general principle is to give priority to the use of memory modules of the same brand and model as the assembly. If you want to expand the capacity, you should also give preference to the brand's memory modules.

2. The low-voltage version can replace the high-voltage version, and the high-voltage version may not be suitable for the low-voltage version (but most of them are still compatible with each other at present.)

3. It is advisable to replace the low working frequency with a high working frequency, and it is not advisable to replace the memory module with a low working frequency, otherwise it will reduce the running speed, or even crash or not work.

4. The slots must be consistent, this is the most important.

5. You don't have to choose a memory module with a check digit.

This configuration is DDR2 generation memory module, depending on the model supported by the motherboard, it is not easy to buy now and it is a second-hand disassembly.

DDR type supported by the motherboard: whether the motherboard supports DDR or DDR2 or DDR3, from the perspective of time, the computers purchased after 2014 are DDR3, and the computers purchased before 2014 need to check the motherboard model, according to the motherboard model.

The frequency supported by the motherboard for DDR: In the supported frequency band, the higher the main frequency, the better.

The maximum capacity of the memory supported by the motherboard: It is wasted if the memory capacity supported by the motherboard is exceeded.

If you want to add memory, you need to purchase the same type of memory, otherwise the compatibility is too poor.

It depends on whether you are DDR2 or DDR3, if it is a new machine, you must use DDR3, which mainly depends on the support of the motherboard and CPU.

Oh, yours should be DDR1, just buy DDR400 memory, but new ones should be hard to buy.

If you bought it earlier, say in '04, it's pretty much SDRAM memory, which is out of production.

Many entry-level DIY players are very entangled in the choice of memory, coupled with the soaring number of memory modules, many brands, and uneven performance, it is even more difficult to choose. Among them, the mainstream memory module brands include Kingston, Corsair, G.QI, Apacer, etc., while there are also many non-mainstream Zhai Tiao, which will not be specified.

Among them, Kingston's memory has a wide range of influence, even if it is a novice, he has heard of it. But old drivers all know that ** is expensive, low playability, average appearance, and stable performance, so when the Ryzen platform first came out, it was recommended to use this brand.

But with the rise of major memory manufacturers, Kingston memory has gradually lost its luster, of which the hacker is a typical example, as an OEM manufacturer, there is no creativity, ** is still so arrogant, maybe three years of after-sales is a bit exciting, but it is difficult to have accidents with this thing in memory. Therefore, at least for now, it is not recommended for everyone to start.

And now there are a lot of memory light bars mainly have several brands, Corsair, G.SKILL, Shadow, Shiquan, etc., the cost-effective one belongs to Shadow, Shiquan, how to choose mainly depends on your degree of faith, rich Pirate Ship, or G.ECH, with gorgeous lights and beautiful appearance. The stability and compatibility can be used both for the Ryzen platform and Intel, and it is relatively stable.

If you don't like the memory with gorgeous lights, then if you are looking for cost-effective and stability, there are the following options, Shiteam, G.SKILL, Guangwei, Samsung, Jintaike, etc.

Finally, there are second- and third-tier brand memory, mainly represented by Sonnet, Hongxiang, Weiqi, etc., these domestic brands are more cost-effective, but the stability is relatively poor, and it is easy to overturn, especially on the Ryzen platform, for entry-level DIY players, it is still recommended to use Shiteam, Gitch, Jintaike and other brands, which are cost-effective and compatible.
