Now it's starting to be peaceful.,The computer has to be constantly upgraded.,In order to catch up with the situation.,2G memory is also peaceful.,Each probably,The larger the amount of memory, the faster the speed of the computer,It is recommended that you have 4G memory。
The brands of memory modules are different, regardless of the size of the capacity, they cannot be mixed together, and the performance indicators are different and incompatible.
Performance metrics for memory.
There are four performance indicators to evaluate memory modules:
1) Storage capacity: that is, the amount of binary information that can be contained in a memory module, such as the storage capacity of the commonly used 168-line memory module is generally 32 megabytes, 64 megabytes and 128 megabytes. DDRII3 is generally 1GB to 2GB.
2) Access speed (memory cycle): that is, the minimum time required between two independent access operations, also known as memory cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.
3) Reliability of memory: The reliability of memory is measured by the mean time between failures, which can be understood as the average time interval between failures.
4) Performance ratio: Performance mainly includes memory capacity, storage cycle and reliability, performance ratio is a comprehensive index, for different memory has different requirements.
-
It is best to use the same brand of memory, as different brands of memory may have compatibility problems and affect the normal operation of the system.
-
You can use more common hardware detection tools, which can detect the model of memory;
-
You don't have to look at that brand, first of all, you determine whether there is a Trojan horse impact, if not, it is recommended that you buy a 2G DDR2 800 directly, the brand is not limited, and then take down your 1G and sell it.
Guangzhou**: 1G DDR2 800 70 yuan.
2G DDR2 800 110 yuan.
Your 1g can be sold for 40 45 yuan when sold second-hand, so why bother to make a 1g back and be incompatible with it to drop to 667
-
1. There are two memory sockets, and the original 1G is composed of two memory modules, so it is best to replace two memory modules at the same time when upgrading to 2G. The replaced slivers, the boss who sells your new slivers will generally **.
2. Copy down the motherboard model, bring the original memory module of the machine to the computer market, and the boss will naturally give you a compatible strip.
3. The motherboard has a memory limit, look at the manual, whether the upper limit of the motherboard can be upgraded to 2G, otherwise the machine will not recognize it, and it will be added in vain.

Landlord, your laptop of this model uses DDR2 memory.
Your configuration is barely enough to cope with the general game, but, big games, it may not be smooth, the generality of the laptop, unless it is the positioning of the gaming notebook, the performance is a little better, but with the desktop, the gap is huge!
Your notebook already has 2G of memory, in fact, in terms of your notebook configuration, at the time, it was not bad, and now, there is no need to upgrade the memory.
You upgrade the memory, to 4G, there is no substantial improvement in your game performance, such an improvement, you don't look obvious, I don't know if you are because the game plans to upgrade the memory, the basic bottleneck of the game, is on the graphics card! So, in your laptop, I don't recommend you upgrade the memory.
Since you asked, I can give you a reference:
Kingston 2G DDRII 800 190 In this way, DDR2's notebook memory,**is 2 times that of DDR3,Because there are less, there are many discontinuations, and there are not many uses,**expensive!
Memory,Actually,You can add it directly,The old one can also be used,If there is a difference in the frequency of the two memories,Automatically downclock the memory with a high frequency to the frequency of the lower one to run consistently!
Why are you planning to change the memory?
-
There should be a label on the back of the console with your computer's n number, which is the serial number.
After you write it down, call 800-860-9999 Haier customer service to ask.
In fact, when the computer is first turned on, it will display the memory frequency value, and if you look closely, you can see it.
-
The next everest test has detailed parameters in it, and generally upgrades the memory modules to choose the same brand and frequency, afraid that the compatibility is not good, in fact, you can consider buying a 512 directly, and now 512 seems to be only about 270 yuan. Haier computers should use adata more.
-
Buying a Kingston DDR 800 2G is enough for about 160 pieces.
-
Kingston, Apacer, ADATA, mainstream are all OK!
-
This machine uses DDRII memory.
You can buy another DDR2 one.
-
It can be upgraded, but even if it is upgraded, it will not improve the performance of the game much. Just run a little smoother.
-
Hello, thank you for asking the company.
DDR3 can have 2G, 4G, 8G memory, you are welcome to ask the enterprise again.
We wish you a happy work life
-
It's a good idea to turn on the machine and see if there are any free memory slots, as all-in-one PCs often use custom hardware.
-
You can add memory, it's more troublesome, you have to remove the host, and the warranty sticker will be directly damaged. Generally, notebook memory is used. You remove a few screws from the back, then take the cover off and you see the motherboard.
The memory is wiped directly to the motherboard. However, depending on the brand and model of your previous memory, some motherboards are not compatible with different brands or main screen memory.
-
There should be two memory slots, which can be added to the after-sales service.
-
Hello, thank you for asking the company.
2. You are welcome to ask questions to the company again.
We wish you a happy work life
-
Hello, 1, can be changed. Go buy DDR3 memory modules. When you buy it, you can say that it is the original.
2. The brand is still different from person to person, depending on your preference.
3,Generally, this book can have 2 memory sticks。
-
Yes, you can buy the same 4G DDR3 1333 or 1600 memory as Samsung, but the operating system must be replaced with a 64-bit one, otherwise you won't be able to recognize it, and the maximum support of 32 bits.
-
The H61 chipset supports larger memory and can be added. Or add Samsung DDR3 1333MHz memory.
-
Hello, thank you for asking the company.
You can buy DDR3 memory, pay attention to the frequency is 1333, it becomes not the same brand, and the compatibility of memory is generally very good.
You are welcome to ask the company questions again.
We wish you a happy work life
-
You can buy DDR3 memory, and pay attention to the frequency of 1333.
Without the same brand, the compatibility of memory is generally very good.
-
If there is a PCI slot in it, you can increase it, try to take it apart and see if you can find out, or buy it ( Samsung DDR3 1333MHz ).
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. >>>More
Kingston, Corsair, Shadow Ship, G.C.C., ADATA, Asgard, Samsung.
The easiest way,Use one-click root (it is recommended that you still use a third-party flashing tool to crack root,z4root just gives you a method,But it's all the same,That is to crack root,You can try bell pepper,Zhuo master,Brush elf,,360,Mung bean,Deep flash, etc.,,,,If it doesn't work,Try the phone crack,Kingroot,Z4root.): >>>More
Buy a brand of memory, and you can generally use it.
Although DDR400 memory is generally available on the market now, many CPUs at that time, especially Intel's, had the default maximum working frequency of the memory determined by the external frequency of the CPU, and many memories were used for frequency reduction. >>>More
The video memory used by the integrated graphics card is to allocate some space in the memory module to use, and the faster the memory, the more obvious the performance of the integrated graphics card will be improved. >>>More
