If the computer wants to change the memory, please look at the configuration and recommend a more co

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!

It is not difficult to replace the installed memory of the notebook, especially for the new notebook, the memory compartment is opened (some notebooks need to remove the back cover to see the memory slot), and the original memory module can be seen.

There are buckles on both sides of the memory module, and if you break the buckle left and right with both hands, the memory module will bounce up 45 degrees and pull out the memory module diagonally.

Install the memory module, put the memory module into the memory slot, put the memory module under your finger, and the buckle on both sides will buckle the memory module, let go.

Especially old configurations, such as the earlier DDR3 memory module (Intel generation and 2nd generation CPU), the memory module needs to choose the same old DDR3 memory module (with a frequency of less than 1333 memory module), if you press ** memory module, it is usually incompatible (no problem for more than three generations).

If you need to add memory by yourself, you need to pay attention to the following points:

Whether the specifications of the new memory are the same as those of the original memory, and whether the main frequency and voltage are the same;

Secondly, whether the whole machine supports expansion, that is, whether there is a free memory slot on the motherboard, you need to consult the notebook manufacturer specifically.

Also, if there is no separate, detachable memory cover at the bottom of the whole machine, you cannot install the memory by yourself, because the laptop within the warranty period, disassembling the machine and installing the memory by yourself may affect the normal warranty of the whole machine. It is recommended to ask an engineer to assist in the installation at the official after-sales service center.

It's very simple, distinguish the type of memory module, low voltage or standard pressure, DDR3 or DDR4, tilt 45 degrees to insert it, pay attention to static electricity.
