Add memory to your laptop, the computer won t recognize the new memory or only 1G 25

Insert the new memory separately, the computer will not turn on, and the old memory can be turned on, indicating that the memory you purchased is not suitable for your notebook. This kind of memory, if not bad, is not very compatible. I have always strongly recommended that when upgrading the computer, the laptop computer will be moved to the seller to upgrade on the spot, and the computer will be copied after the upgrade, and then pay after normal, and solve the problem on the spot.

If the conditions are limited, try to buy the same varieties as the brand and particles, and check whether it is ** on the spot.

You didn't give a clear account of the specifications of the new memory. In fact, there is also a question that must be considered when upgrading memory, that is, what kind of memory the motherboard supports at most. If the memory board you purchased does not support it, it will not be able to be used even if the memory is not broken.

For example, in the past, some notebooks supported up to 1G of RAM per slot, and the total of notebooks supported up to 2GB of RAM. If you buy a single 2G memory, the laptop will not work properly.

When is the landlord's notebook machine?,If the memory is DDR400, use 400 memory to add up,The new memory module is not supported by the old motherboard,Generally speaking, the old motherboard should add old-fashioned memory,The old motherboard can't play with the old memory.。

Whether you use DDR2 or DD3 memory sticks, there should be a conflict between the two different ones, and there is also a conflict between the old memory and the current one, it is best to use the same model such as DDR2 800.

If the RAM space is too small, the running memory is too small. The solution is to install additional memory modules to increase the running memory.

Memory is an indispensable component of a computer (PC, MCU). Unlike dispensable external memory, memory is a component that reads and writes on a bus; Memory is more than just a data warehouse.

A memory module (abbreviation: RAM, also known as: random access memory) is an internal memory that directly exchanges data with the CPU, usually as a temporary data storage medium for the operating system or other running programs.

When working on a memory module, information can be written (deposited) or read (withdrawn) from any specified address at any time. The biggest difference between it and ROM is the volatility of the data, that is, the data stored in the event of a power failure will be lost.

Memory is an indispensable component of a computer (PC, MCU). Unlike dispensable external memory, memory is a component that reads and writes on a bus; Memory is more than just a data warehouse.

In addition to a small number of indispensable programs in the operating system to reside in memory, the programs we usually use, such as Windows, Linux and other system software, including typing software, game software, etc., although a large amount of data including programs are placed on external memory devices such as tapes, disks, optical discs, mobile disks, etc., but any data in external memory can only be really used when transferred into memory.

Any input (from external memory, keyboard, mouse, microphone, scanner, etc.) and any output (display, printing, audio, writing to external memory, etc.) on a computer can only be made through memory.

First, you need to understand a few concepts:

Memory, refers to the memory that directly exchanges information with the processor when the computer is running, which is very fast, but the information will be lost when the power is off.

External memory is a device used for long-term storage, and it is still there after a power failure. But it's a lot slower than memory. Generally, external memory is a hard disk.

The computer's operating system manages the use of memory, and if the memory is almost full, it will delete or put parts of the memory into external memory. It's just that the computer will run slower.

I think when you say memory full, you mean hard disk full.

When the hard disk is full, the main thing is to clean up some useless content. For example, the computer version of QQ, the ** ** of WeChat storage, etc. It is recommended that you can go to some computer manager software, which generally comes with a cleaning function.

However, it is recommended that you uninstall these butlers after cleaning up. Because they also take up system resources, making the computer run slower.

1. Use disk cleaning software to clean up the C drive, which can free up about 50M-800M space for the C drive.

2. Turn off the sleep function, enter the powercfg -h off command in the start menu to turn off hibernation, the actual size of this file is the same as the physical memory, which can free up 1-3G space for the C disk.

3. Click "Clean Trash" on the main interface of PC Manager, confirm that the relevant garbage type is checked, click "Start Scan", and then click "Clean Now".

Right-click on the C drive, select Properties, and click Disk Cleanup to the right of the capacity.

Find the files that can be deleted, and then click OK to delete them to clean up the C drive.

The technical content of the notebook computer, the difficulty and cost of counterfeiting is very high, so there is generally no counterfeit and shoddy, due to the existence of the battery, the notebook is equal to the installation of the desktop, and the up space of a long-delay ** work is small, which can optimize the office environment.

The first thing you need to understand is that memory modules are used for read-only memory (ROM) and cache. Simply because RAM is the most important memory of them all. The function of the hard disk is to store and read out the function, mainly to remember your usual data and where the system files are, which is like a disk that has been rotating, there is a needle on the disk to write and read the data, and the function of the memory on the computer is a data transfer station!

It's used to store data temporarily!

The difference between it and a hard disk is that it is stored temporarily, and the data disappears when the power goes out. Let's make it clear!

The hard disk is equivalent to the warehouse of the factory, and the processor is equivalent to the processing workshop! Data is transferred between them! The speed of data output in the warehouse is slow, and the processing speed in the processing workshop is fast! The result is a contrast, and it's huge!

In order to alleviate this gap, the memory is increased, if the transmission speed of the hard hail Xiao disk is 1, then the memory is 10, and the processing speed of the processor is 1000, from 1 to 100 The difference is a hundred times, and the memory is added, it is basically alleviated!

Of course, this is not absolute!

A hard disk is a permanent storage device, as long as it is not broken, its data will not be lost, and it is good for storing large-scale data! The memory is not good, as long as the power is out, the data is gone, but it is quite fast! Understand no source socks.

The memory in the computer is a medium for the computer to exchange data, all the data is stored on the hard disk, first read into the memory and then the CPU processes the data, and the data in the memory will be emptied after shutting down. It is two concepts with the memory of Changgao in the mobile phone, and the memory in the mobile phone is equivalent to the hard banquet disk in the computer, and you see that the hard disk capacity and memory are two storage media.

You're adding memory, not a hard drive, and of course the hard drive capacity hasn't increased.

Laptop memory is not the same as hard disk capacity.

Hello, for your question :

1. In your case, you should be able to see two memories in the BIOS POST, while only one memory can be displayed in the system.

2. In this case, it may be a memory module hardware compatibility problem - that is, your motherboard may not be very good for the 2G memory module compatible type, so please check the motherboard memory slot support parameters and the parameters of the two memory modules.

In general, high-frequency memory can be used with reduced frequency, but low-frequency memory cannot be installed on motherboards that do not support this frequency.

3. If possible, it is best to change a memory module and try again.

If you have any other questions, please feel free to consult the computer manager business platform, and we will serve you wholeheartedly!

1: Caused by poor contact between the memory module and the motherboard memory slot. (Just wipe its gold finger back and forth with an eraser to solve the problem).

2: If the motherboard is incompatible with the memory module or the memory module quality is not good, you can try to reduce the memory read speed in CMOS to see if the problem can be solved.

Three: The general slot has 2 4 hungry slots. However, the memory slots of the motherboard that support dual-channel are generally 4 (there are exceptions), these 4 memory slots are divided into two groups, A, B, when A1 and B1 or A2 and B2 two empty memory slots are inserted at the same time two memory sticks with the same capacity and structure, in order to achieve dual-channel memory work mold early picking.

If you install a singular memory module, you can only implement single-channel mode.

The memory is not recognized, and it may be a compatibility issue between your computer and the new memory. Try 2 memory swap positions.。。

Try to swap the positions of the two memories,Still can't identify it's a compatibility problem.,Or there's a problem with the slot of the memory.,If it doesn't work, change the machine.。
