Does the laptop plus memory have to be exactly the same as the original one?

If you add 1G directly, you have to make sure that the motherboard supports more than 1G of memory. But in terms of laptop performance, you don't need to add 1G, because such a motherboard and CPU have 512M memory, and the performance of a 1G computer is about the same. You might as well add a root 512m and forget it.

If you want the memory to be stable, the frequency of the memory should be the same as the brand.

No matter how big the memory of a computer like yours is, it can't fit Vista. Because your graphics card is integrated. And the motherboard and CPU can't keep up with the basic configuration of Vista.

It can be added larger than the original! No matter what system you install, this hardware warranty will not be indispensable.

It should be DDR2 memory Because your processor is Xuanlong's My book is also Xuanlong's, it is recommended that you use the memory of the same capacity as the regular manufacturer, in fact, it is very good to upgrade to 512, there is no need to upgrade too much, after all, it is a notebook, if you want to play games, it is better to buy a desktop computer, it is definitely no problem to upgrade to 1G, but it is best to use the memory of the regular manufacturer's DDR2.

Not necessarily, but the brand should be the same, and the most important thing is that the black particles on it should be consistent, or similar, otherwise there will be problems.

It shouldn't work, I can't install vista

Yes, but 2666 will be downclocked to 2133, and the system will not allow two memory modules with different frequencies to run at the same time.

Theoretically, yes, but if the hertz number is too high, it seems to affect the network speed response.

It is possible to hold memory modules of different memory sizes. However, it is best to meet the same frequency as the original memory, the same memory brand, and the same capacity of the two memory modules. It is best not to be one large and one small, there will be some differences in the design voltage and component performance of different brands, so as to avoid compatibility errors such as crashes and blue screen restarts caused by different brands and different capacities.

It is possible to install memory modules with different memory sizes, but it is recommended to install two 4G (64-bit maximum support for 8GB memory), so that there will be no incompatibility problems.

Use W7 to use 2 4G, this system consumes resources, 1 1G and 1 4G will have compatibility problems sooner or later, and now the memory is not expensive.

Theoretically, yes, the memory is logically encoded for reading, that is, the memory usage is not necessarily continuous, and the address can be accessed, however, Intel supports dual-channel technology, that is to say, the effect of 2G+2G is about 20% higher than that of heads-up 4G, so it is recommended to buy two 4G directly, which is the maximum memory supported by this computer.

The two are not the same size and are usually not a problem. At most, it's just a slight loss of performance, so small that you can't feel it.

It is recommended to 4gx2, anyway, the memory is not expensive, and it is yourself who is cool in one step.

It is recommended that you install one 4G or two 2G ones, and if you pretend like that, the system will crash.

It's okay to change.,But the XP32-bit system supports up to 3G,Win732-bit seems to be 6G.,According to the system and needs.,Generally, a notebook like yours4G is enough.。

64-bit is OK.,Compatibility is not a big problem with a brand.,But if there is always a black screen or you can't turn on the machine, it is recommended that you take down the 1G bar.。

There are several principles that need to be followed when adding memory to notebooks and bench test computers.

The installed memory is the same as the original frequency, if the frequency is not compatible, there will be unstable work and crash.

The memory brand of the same machine is the best to be the same, because there will be some differences in the design voltage and original performance of different brands, if there are conditions, it is best to use the same brand of memory.

The capacity of the two memory modules should be the same, and it is best not to be large and small.

If the conditions cannot meet the above three conditions, it depends on the performance of your motherboard. Some motherboards have a single memory.

The slots have independent voltage control. The conditions for the installation of such a board can be relaxed.
