What type of memory module can be used with Lenovo ThinkPad X201i 3249J4C? Which brands of SSDs are

Dear users, hello!

The memory specification of the X201i is 1066MHz DDR3, the number of memory slots configured on the computer is: 2, the maximum capacity of a single memory slot is 4G, and the maximum memory capacity of the whole machine is 8G.

In order to eliminate compatibility problems, it is recommended that you bring the actual test of the machine when you buy it and then add it after it can be used normally. Or negotiate with the dealer to help you replace it if there is an incompatible situation, so as not to affect your subsequent use.

If you upgrade the SSD, there are no strict requirements for the brand, mainly to pay attention to the compatibility situation, it is recommended that you test it before purchasing or negotiate with the dealer to help you replace it if there is an incompatibility.

Check the specifications of the standard hard disk of your machine is sataii inches, you can refer to the following. ‍

It is best to maintain the same specifications as the standard configuration of the additional memory, there are not too many requirements for the brand, it is recommended that you install the memory produced by regular manufacturers, such as Kingston, Samsung, etc. In order to rule out compatibility issues, it is recommended that you bring the machine with you when you buy it, and then add it after the actual test can be used normally. Or negotiate with the dealer to help you replace it if there is an incompatible situation, so as not to affect your subsequent use, and the installed memory is best to maintain the same specifications as the standard configuration, there are not too many requirements for the brand, it is recommended that you install the memory produced by regular manufacturers, such as Kingston, Samsung, etc.

Just take a look at the disassembly.

Yes, the ThinkPad X201i (32493HC) supports DDR3 1066MHz type memory, and the maximum support is 8GB.

Installation method: 1. Shut down and disconnect the power cable and network cable;

2. Close the notebook and flip it to the bottom of the notebook;

3. Remove the battery;

4. Remove the palm rest of the notebook;

5. Find the grooves on both sides of the memory;

Note: To prevent damage to the memory, do not touch the bottom edge of the memory;

6. Insert the memory into the memory slot (1) along an angle of about 20 degrees, and then force down (2);

7. Press down on the memory until you hear the click of the memory in place;

8. Ensure that the memory is correctly put into the slot and will not be easily moved;

9. Reset the palm rest of the notebook (note: before the palm rest is reset, the notebook cannot be powered on);

10. Reset the battery, reconnect the network cable and power cable, and turn it on.

Of course.

A 32-bit computer uses 32 address lines, so the memory address it can represent is up to 2 to the 32nd power B, which is converted to 4G in GB and 0000 FFFF (hexadecimal) in physical address. That is, the maximum memory it can recognize4GB,But the system itself has to occupy a certain amount of memory,And some limitations in actual use,Win7The maximum memory that the 32-bit system can use is。

In the same way, 64-bit uses 64 address lines, and the maximum memory that can theoretically be recognized is theoretically 2 to the 64th power b, which is particularly large. However, it is not possible to use such a large memory capacity at present, so the 64-bit system of Win7 does not use all of them, and the maximum amount of memory it supports varies depending on the version: Windows 7 Home Basic (Home Edition) only supports a maximum of 8GB of memory for 64-bit, Home Premium (Professional Edition) supports 192GB of RAM, and Enterprise and Ultimate (Ultimate Edition) supports 192GB of RAM.

The x220 can expand the memory module with an empty slot that can be added up to 8GB of memory.

You have to change the operating system, change to 64-bit, 32-bit does not recognize more than 4GB of memory.

Almost all computer memory can be expanded.

The technical parameters of the expanded memory are as consistent or close to the original memory as possible.

Lenovo said that it only supports 8GB,But the actual 8*2 is OK (at least i5-level U),But you have to try.,It's a bit of a stroke of luck.。

I am now a Kingston D3 1600 8G*2, and I tried and changed it for a long time before I succeeded.

The estimation of i3 is not good, because the 8G strips are all 1600, and the i3 is up to 1333 at most

In fact, under normal circumstances, 8GB is completely sufficient

However, the 2G frequency that comes with the machine is 1066, and the current 8GB single bar is at least 1600, and they must not be able to mix and match.

It is still recommended that you use it directly4G 1333*2=8G,On the one hand, there is no problem with compatibility,On the other hand, the performance of the two memories can also be maximized,There will be no one of them dragging its feet,And 8GB memory is enough normally,Use X201i's not to run ae 3ds max on this,If you play large games,The bottleneck is not in the memory,So if you want to upgrade, the original 2G will be collected by yourself,In case of emergency。
