Win7 System computer Upgrade memory What are the considerations?

　　First, the need for memory upgrades

The impact of memory on the overall performance of the desktop is well known, while the notebook computer memory in most of the use of shared memory, video and other storage functions, so compared to the notebook computer memory for the overall performance of the impact of more significant,

With the increasing volume of software, the version of the continuous upgrade, but also to the system to put forward a higher demand, the past notebook computer mainstream 1G memory configuration is increasingly unable to meet our needs, especially in the image processing may even occur when the memory is insufficient. Therefore, it is necessary to upgrade the memory.

　Two, memory upgrades need to consider 2 factors

Upgrading your laptop memory is somewhat different from upgrading your desktop memory, and be aware of the following 2 points:

1, Volume

Because of the high integration of notebook computer, design precision, so in the same capacity to choose a relatively small size of the memory, so as to reduce the insertion of memory with other parts of the opportunity to collide, and small size of the memory can be very good to avoid the electromagnetic interference between accessories, but also conducive to cooling, so as to ensure the stable operation of the notebook computer.

2, capacity

In pursuit of small size, notebook memory slot is limited, most laptops have two 144-line DIMM slots, upgrade space is relatively limited, in order to avoid future memory capacity as a bottleneck affecting performance, it is recommended to choose a single large capacity of memory, In addition, fewer chips in memory in the operating state of the calorific value is also low.

Three, Memory algebra: Now the memory has been developed for many generations, the main memory is DD3, if you want to add memory, then you need the same model as your computer, or you can not match.
