What kind of memory module to use, and how to choose a memory module?

Motherboard physical information.

CPU socket (slot) 1 LGA775

Expansion slots 2 PCI, 1 PCI-E x1, 1 PCI-E x16

Memory slot 2 DDR2 DIMM

Motherboard integrated devices Audio, Video, LAN form factor Micro ATX

Motherboard chipset SIS662

Your motherboard is a SIS motherboard, the compatibility is not good, and the memory is more picky. When you buy memory, it's best to hold the machine and try it before you buy it. You can buy two 1G DDR2 667 sticks.

It is recommended not to mix it with the previous memory module, and it is best to buy two new slivers of the same specification and model.

1.Find out what your motherboard is, check out the maximum amount of memory it supports, and how many memory module slots it has. Some have only one slot, while others contain two.

2.Desktops and laptops have different slots for memory modules, and the arrangement of the gold fingers of the memory modules is also different. Desktop memory modules are longer, while laptop memory modules are wider and shorter.

3.Nowadays, the average memory is three generations. i.e. DDR3.

DDR3 is different from DDR3L. DDR3L means low pressure, ie. And DDR3 is.

Therefore, you should pay attention to this detail when purchasing. Otherwise, incompatibility may occur.

4.The operating frequency is also the most important parameter. The general memory operating frequency is 1600MHz and 1333MHz.

5.If you know that your computer can increase memory, the safest way to buy is to use a hardware detection tool to check the memory information of the computer. Buy the same memory module as the original.

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 principle of allocating memory.

It is best to match the size and frequency of the brand. This makes it easier to perform its function.

The main thing is that the frequency should be the same.

The 1+2g allocation is not optimal. That's also faster than a 1g or 2g one, so what's that. To buy 2g personal recommendation.

Same brand of 2G DDR3 1066 as the original one. Last time I added a 2G one to my own Y460.

Micron MT 2GB 2G DDR3 1066 notebook memory Support Lenovo Y450 Y550 (150 oceans can go to **search for a link, the answer will take half a day to come out) I use it very well.

Add 2G good,Just 3G,The system doesn't need to be installed64Bit,Now the notebook memory is not high**2G's is about 140,It's best to have a memory of the same brand and frequency on your computer,It doesn't affect the warranty,You now 1G memory is indeed a little small,Add to 3G The speed increase will be more obvious。

It is recommended that you continue to buy a memory module of the same model as the original, and 2G can play a better performance under win7 conditions!
