How to make the memory reach the optimal

You can not consider other problems of the system, but I believe that everyone has some research on the memory problem, although it is now a big memory era, in the civil memory for computer memory There is a saying that is: the bigger the memory, the faster the computer. So I believe many people will subconsciously agree to the Xiaobian's formulation when they see this problem. The reason is very simple, 1GB is faster than 512MB, then 4GB is of course faster than 2GB! But in fact, the industry knows that many times more memory does not mean that your computer can be fast-paced, sometimes at some low On the end configuration, the actual effect of large memory is not as good as the small memory before installation.

Why? Actually, there are many reasons for this problem, but in most cases, the current computer does not have the need for such a large memory space (you can use the task manager to pay attention to the amount of free memory), many The memory is so freely empty, and the opposite space takes up more system addressing time, which is why the memory is increased and the computer is slower.

So in today's era of memory cabbage prices, we really do not need to configure a second memory for the love machine? I believe that these small tricks should be exactly what you want to know.

1. Clever use of dual channel

Configure a dual channel memory for your computer, which is the most efficient of all memory multiplication schemes, because it is the only one that can physically make memory directly Bandwidth multiplication operation scheme.

In a nutshell, the dual-channel architecture consists of two independent memory controllers on the motherboard. When two controllers have a set of memory, the two controllers can easily implement each other. Zero waiting time.

Switch to a more popular analogy, that is, two groups of trucks are running in the same two lanes at the same time, so that after arriving at the destination, the goods that are transported at the same time must be more than the previous truck (single strip) More memory (more than double the theoretical single channel), and this is the best interpretation of dual channel memory.

So what do you need to pay special attention to when setting up a dual channel? No, in fact, this technology has been popular in DIYer a few years ago, and the current motherboard supports almost 100% of the dual-channel architecture. And with the upgrade of the technology over the past two years, today's dual-channel has long been unlike the previous one, but also specifically looking for a second memory with consistent capacity and similar performance.

As long as your motherboard supports the so-called "Flexible Dual Channel" technology, no matter how much memory is inserted in the first memory controller (usually two sets of slots), regardless of whether the memory capacity is the same, as long as In another memory controller slot (the color will be different from the first controller slot), insert the corresponding capacity of the memory (such as 2GB on the left side, then insert 2GB on the right side), the system will automatically match and form a memory double Channel, performance is not affected.

2. Optimizing the system

In addition to the physical dual channel, the registry is another factor that determines the performance of the large memory. After all, the wheel has to change the engine to force it! The following is a simple list. Two registry entries related to memory performance.

Note: The following items are located in the registry [HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\SessionManager\\MomoryManagement]

* “LargeSystemCache”: This function is to open up a space in memory For file read-ahead operations, it works a bit like the Prefetch that comes with Wndows, but the data stored is different. By default, the key value is “0”, indicating that the system cache is 4MB, and when we change it to “1”, the cache will change from 4MB to 8MB, obviously when you have a larger memory, This key value is necessary to open.
