ASUS K42JA supports a large amount of RAM

Dear ASUS users, the K42JA supports DDR3 1066 MHz memory, 2 x SODIMM expansion slots, and the system memory can be expanded up to 4GB RAM (requires operating system support).

The ASUS K42J can add RAM, but only 2GB of DDR3 1066MHz RAM, because the maximum memory capacity of this student is 4GB.

1. Turn the laptop over and remove the two screws.

2. At the empty memory slot, insert the memory at 45 degrees, push it into place, press it down, and it will be stuck into the memory card slot.

3. Put the lid back and fix the screws.

It's definitely possible, two memory slots, you only use one, plus 4G of memory.

OK.. This is who I am ... I also changed the SSD, I brought my own Kingston.

Dear ASUS users, Hello!

1. K42JZ has 2 x SODIMM memory slots, supports up to 2 4G memory, and supports DDR3 1066 1333MHz memory.

2. It is recommended that you can buy Elpida, Hyundai, Samsung, Kingston, and other brands of memory, due to the compatibility of electronic products, it is recommended that you bring a notebook to install and test the compatibility when purchasing memory.

This is the memory description of the K45JZ on the official website of ASUS:

Supports DDR3 1066 MHz memory, 2 x SODIMM expansion slots, and the system memory can be expanded up to 4GB memory (supported by the operating system).

The actual operating frequency of the memory is related to the chipset and CPU frequency.

It can't be a 4G or a 2G.

i3's u, why do you have such a large memory? Two 4G ones are sufficient.

I used CMD to test that it also supports the maximum 16G, but I bought Kingston's 8G and 4G memory modules, and they can't be lit up, and then I checked it to know that the maximum support is 4G memory (but I only plug in a 4G memory or can't turn on the machine), it is recommended to buy a 2G of the same model must reach the memory, do not use Kingston's incompatibility.

Landlord, what memory module did you add at the end? I bought a Walston DDR3 4G like your computer, and I can't turn it on when I install it.

Dear ASUS users, Hello! The ASUS K42J laptop supports DDR3 1066 MHz RAM, 2 x SODIMM expansion slots, and the system memory can be expanded up to 4GB RAM (requires OS support), which means that it supports up to 2 x 2G RAM. K42J supports dual channels, and two memories of the same frequency and capacity can form dual channels.

Due to the compatibility problem of memory, even the same brand and specifications may be encountered, it is recommended that you buy the memory on site and test it before purchasing.

1: ASUS K42JE laptop supports DDR3 1066 MHz memory, 2 x SODIMM memory expansion slots.

2: The system memory can be expanded up to 4GB memory, that is, it supports up to 2 2G memory; Dual-channel technology is supported.

The positioning of ASUS K42J is the same as that of the previous all-round notebook A42J, but there have been great changes in appearance and configuration, perhaps thanks to the hot sales of the N82 series products, ASUS K42J not only continues the classics of the A42J, but also adds a lot of excellent design and craftsmanship of the N82 series. In fact, ASUS K42J is very similar to N82 at first glance, but the N82 metal shell material has been turned into plastic, but it retains the N82 engraving pattern process, and at the same time, the technology of printing in the film is also used on the surface, which not only makes ASUS K42J have a fashionable and avant-garde appearance, but also has better scratch resistance and wear-resistant protection, and also dilutes the residual problem of fingerprints.

2 memory slots, supporting a maximum of 2GB memory per root.

The maximum memory for this notebook is 4GB.

The type of memory is DDR3, standard voltage version, and the frequency is 1066.

If you want to expand, it is already difficult to buy 1066 memory, you can use 1333 instead, but it should be noted that it is best to be double-sided 16 particles to be as compatible as possible.

My notebook is this model.

Two single 4G memory are installed, for a total of 8G memory.

Packed with a 500g solid state.

Windows 7 64-bit, be sure to use the 64-bit system, because the 32-bit system does not support 8G memory, the screenshot is as follows:

Dear ASUS users, Hello!

The K42D series can be equipped with a maximum single 4G DDR3 1333 memory.

1. First of all, it is recommended to buy at the service center, which can test whether the machine is stable after installing the memory, and enjoy the national warranty;

2. If you install the memory yourself, please buy the memory of big brands, such as Nanya Yisheng and Hynix.

Apacer, Kingston.

Wait. 3. When installing memory, please disconnect the power supply, and plug in firmly when installing memory. After installation, whether the running machine is normally started and whether it is running stably;

4. If the machine memory reaches or exceeds 4G or above, it is recommended to install a 64-bit operating system.

32-bit system, does not recognize 4G and above memory.

Hope you find the above information helpful! Thank you!

Further consultation with the engineer, thanks!
