The Asus k40I has several memory slots

2 slots, you can add memory.

In addition to the onboard 4GB or 8GB of RAM, this ASUS laptop also has a memory expansion slot that supports DDR4 2133MHz memory, with a maximum support of 8GB for a single memory and up to 16GB of system memory (requires OS support).

ASUS notebook computers can basically be upgraded to add SSDs, even if there is no reserved SSD space, you can also consider replacing the HDD bay or the blind optical drive bay with an SSD.

Of course, whether it is to upgrade the hard disk or modify the SSD, or to add memory, internal cleaning, etc., it is recommended to send the laptop to the official ASUS after-sales service center, and it is safer and more secure for professional maintenance engineers to disassemble and upgrade, and you can also confirm whether it can be used normally after the installation and upgrade.

1. Prepare the memory module, computer and corresponding removal tools.

2. Close the laptop and remove the battery, and disassemble the back cover of the laptop.

3. Insert the memory module into the red box in the above figure (right), and hear a "pop" sound, and the installation is successful.

Dear ASUS users, Hello!

The machine has two memory slots, supports DDR3, and supports up to 2GB of memory for a single strip, which can be expanded up to 4 GB of memory.

If there is only one 1GB memory on the machine, you can also add a 2GB or 1GB memory.

As a reminder, the XP 32-bit system supports up to 3GB of RAM, and if you use two 2GB of RAM, you can only use 3GB

This can add memory, but it doesn't have much effect, because the CPU and memory are inseparable.

ASUS K40ie notebook memory module method:

1. Prepare the memory module, computer and corresponding removal tools.

2. Close the laptop and remove the battery, and disassemble the back cover of the laptop.

3. Insert the memory module into the red box in the above figure (right), and hear a "pop" sound, and the installation is successful.

4. The installation is completed as shown in the following figure:

Judging from the configuration, it should be DDR3 1066 strips, a single 2G is no problem, two can be expanded to 4G, no matter how big it is, it's an old computer.

Hello, dear ASUS users.

Your model has 2 RAM slots and supports DDR3 1600 laptop memory. A single memory supports a maximum capacity of 4G. Here it is recommended that you better buy and install memory on site for testing, it should be that the memory has compatibility problems, which is more secure.

1. By default, it should not be a crossfire, you need to DIY yourself, and the specific method is still;

2. This should have two memory slots, and you can remove the two screws shown in the figure below and see it yourself, which will not affect the warranty;

GB memory running 64-bit system is indeed a bit tight,Boot to consume about the memory,2GB open a few more programs is almost the same,The card is also a normal reason;

4. To add memory, from a practical point of view, adding 2GB is basically enough (mine is 4GB with 64-bit system), if you want to have a little surplus, of course, 4GB, the composition of dual channels is not affected, the memory is more expensive, or recommend 2GB... If you buy it in a physical store, it is recommended to bring it with you and light up the payment, which is better.

Dear ASUS users, Hello!

1. K42JV supports DDR3 1066 1333 MHz memory, with 2 x SODIMM memory slots, and supports up to 2*2G=4G memory.

1. Prepare the memory module, computer and corresponding removal tools.

2. Close the laptop and remove the battery, and disassemble the back cover of the laptop.

3. Insert the memory module into the red box in the above figure (right), and hear a "pop" sound, and the installation is successful.

4. The installation is completed as shown in the following figure:

It's easy to add a memory module, just remove the back cover.

ASUS K40AB uses DDR2 memory modules, and it is estimated that your 4G memory modules are DDR3, because 4G DDR2 memory modules are rare. You can't use this memory stick.

You can add it, but are you sure that the frequency of the two memories is the same? Using memory at different frequencies together will cause the higher frequency memory to be backward compatible with the lower frequencies, and may also cause compatibility issues.

As for how to add memory, you open a cover at the back of the notebook, and you can see the memory, which is a relatively small cover.

How to add memory to ASUS K40AB:

Turn off the power of the computer, then fold it, lay it flat on the table (back side up), in order to prevent the computer from scratching, you can put some flexible newspaper or towel under it;

The screws on the back case of the laptop are relatively small, so you need to find a suitable screwdriver; (Note that when using a screwdriver to remove the screws, you must not use large force, otherwise the screws will be troublesome if they are broken);

After the locking screws of the back case of the laptop are removed, open the back case of the laptop very carefully; (In addition to using screws to fix the back shell of the notebook, there are buckles, do not use brute force, and then you can't use things to warp, and there are parts under the back shell to avoid damaging the computer);

Pick up the memory module you bought, unpack it (remember not to damage the packaging, when you encounter a mismatch, you can replace it) When replacing the memory for the laptop, remember to try to buy the same model as the previous memory of the computer; (If you don't understand, you can check some information first, and then buy memory after you are clear);

Notebooks have two memory sockets, and there is a blank socket above the original memory module.

The memory is not installed correctly, and the R port on the memory must be matched with the one on the computer;

After the memory is placed, you can follow the original disassembly method, tighten the laptop lock screws, when the computer's memory increases, the computer will have a qualitative leap.

Below** is the back of your notebook of this model, the upper right corner of the cover is about ten centimeters long and wide, open the inside and you can see the memory module. There is a lock next to it, push the lock through, and then there is a small protruding clasp, and you can uncover it.
