Look at the ThinkPad for yourself

What kind of memory R400 is, you can see it in the system.

Generally, the DDR3 generation 1066 loan width is different, one is high and the other is low, and it can only run according to low bandwidth

Y450 compatible memory brand can call Lenovo customer service for consultation, in addition, it is not recommended to buy TB of memory, fakes, grinding strips are the majority, and there is no guarantee after sale, you can buy it at the local memory franchise store, and you can replace it free of charge if there is an incompatibility problem, and the price difference will not exceed 5%.

Dear users, hello:

To expand the memory of your laptop, you need to pay attention to compatibility issues, and you had better choose the same brand and frequency memory as the previous memory. If you replace the memory, you need to pay attention to whether the memory module is supported by the motherboard and CPU.

If you wish to change your operating system, please back up your personal data in case you lose it. For the specific operation process, you can consult the local repair center.

To inquire about the repair center, please log in.

You know Lenovo can add memory sticks.

Is it? Here's what I brought to Lenovo Y450 if you can add memory sticks, welcome to read!

Lenovo Y450 Add Memory Module Method:

Can be added. The easiest way to get rid of static electricity on your body is to touch something metallic with your hands.

Look at the front and back of the memory, see how the memory that comes with the machine is plugged in, and the memory is golden.

The notch is aligned with the protruding part of the slot, inserted in that way, the two big fingers are pressed down hard, and then the clips on both sides are pushed inward and stuck, there is a snapping sound, indicating that the insertion is in place, as shown in the figure.

If there are two memory slots on the motherboard, it goes without saying, if there are four, method A 1 and 3 two slots should have memory insertion at the same time, 2 and 4 should have both, not 1 and 2 or 3 and 4 will not work. Motherboards are read separately for odd and even slots.

Method B: Insert two slots of the same color at the same time.

Plug in the keyboard and mouse power supply, boot the test run to experience it, see if there is any imaginary speed, it is faster than before, there is no problem, shut down and cover the chassis cover, screw on the gong wire, and the memory will be added.

Hello, as shown below, inside the machine, it is not recommended that you disassemble the machine by yourself:

It is an honor to serve you, I hope it can help you, and I wish you a happy life.

In fact, there are many ways to check the memory of the computer, and it is very simple, I believe you can learn it by watching it once!

The first method: we only need to right-click on the "computer" icon and select the --properties option to see the computer memory information.

The second method: through third-party software viewing, we can **Master Lu, 360, Kingsoft Poison Bully, Computer Manager, Drive Elf, etc.

The third method: use the hardware viewing tool that comes with the computer to view, we can enter dxdiag in the start menu - run - and click OK to view.

DirectX Diagnostic Tool.

We can only see that the memory size is 6g, and the memory frequency is really not visible.

The fourth method: view the memory information under the dos command. Start - Run - Enter cmd - Enter the command systeminfo and press Enter.

dos command.

You can also use the dos command to see the memory information, but you can't see the memory frequency, but you can actually see it.

The fifth method is: open the computer to check the memory side macro tag, but this method is really unreliable, Uncle Xue has three memory modules in his hand, but only one marks the memory size and frequency, in fact, this method is still not advisable!

The second question: Can memory sticks of different frequencies be mixed?

The answer is: it can be mixed. I can tell you this, your computer motherboard supports 1333 1600MHz DDR3 memory, then your computer can be plugged in at the same time 1333 and 1600MHz 3rd generation memory module, but your 1600MHz memory module frequency will be reduced to 1333MHz, which is the short board effect!

Another thing to talk about is that when the memory size is greater than or equal to 4G, the 64-bit operating system must be installed, otherwise the 32-bit operating system will not be able to fully use all the memory! Remember.

The GT240 is indeed welded on,Lenovo service station only provides hardware replacement for ordinary maintenance and physical interfaces,You want to return the original welded hardware replacement to the factory,**Lenovo has to charge you at least 200 more manual money without the cost of the graphics card。

2.Originally, Y450 is 2G memory, there are indeed 2 DDR3 memory slots on the motherboard, but I don't know which batch of goods yours is, some are 1 2G, some are 2 1G, it is recommended that you have Master Lu to look at the hardware information.

The CPU is T6600,Memory is counted as you upgrade to4G,But you can't upgrade the motherboard,No matter how you upgrade, it's impossible to install a 64-bit operating system,So the computer only recognizes you as a little more than 3G memory,Graphics card GT240There is nothing to improve,It is recommended that the landlord does not waste money,If the landlord thinks that playing Warcraft Cataclysm what card,It's normal,Warcraft eats memory,Not a graphics card。 So I highly recommend that you don't need to change your graphics card!

All hands played, the landlord himself and the upstairs comparison, begging to adopt

There are only two notebooks with memory slots, and you're 2G. It is possible that two 1g ones have been inserted, and it is possible that one 2g one has been inserted, and you can use Master Lu to see the details. If it is two 1G ones, it is recommended to buy a 4G one to replace it.

As for the graphics card, the notebook graphics card is really hard to find, go to a large computer store to find it, bring the machine over, and then go to the ** to find it, there is really no way to go to the after-sales service. Be sure to take the book apart to see which graphics card you can press.

It just so happens that I'm also 450.,I'm planning to upgrade.,Just called** to the Lenovo maintenance station,The staff said that the graphics card and CPU don't need to be replaced.,Just add a 1G memory stick.,32-bit system4G memory can't be recognized.,There's no need to upgrade the memory while removing the dust of the whole machine for free.。

Memory can be added, but if the service station is changed, you can only change the motherboard as a whole, the ocean is indispensable, it is not cost-effective, can you change the BGA soldered graphics card? If the welding is not good, it will be welded, so be careful.
