How do I optimize the CPU?

First, optimize the CPU in the BIOS

1, open CPU level two cache

For some special motherboards, some features of the CPU are not turned on by default, and they need to be turned on in the BIOS, such as internal CPU cache and Hyper-Threading technology. The way to open the internal cache for the CPU is as follows:

Step 1 Enter the BIOS setup main interface, select the "Advanced BIOS Features" setting, and press ENTER.

Step 2 Sets "CPU Internal cache" to "Enabled", that is, open the CPU level two cache. When opened, it can reduce the CPU wait time in the memory read/write cycle, thereby increasing the CPU efficiency.

Step 3 CPU Level two cache ECC checksum is also an important parameter. Set CPU L2 Cache ECC Checking to Enabled, enable CPU internal L2cache, and perform ECC detection. It can detect and correct unit signal errors, maintain the accuracy of the data, the stability of overclocking is helpful, but can not detect dual-digit signal errors.

2. Set up Hyper-Threading Technology

Hyper-Threading technology enhances processor performance and productivity. Therefore, for some CPUs that support hyper-threading technology, such as P42.8C, you can set them as follows:

Step 1 enters the bios of the motherboard and finds "in the Advanced BIOS Features"

hyper-threading Technology "option.

Step 2 Set it to "Enabled."

Restart the computer after step 3 is set up, and then display two processors in the post screen. When a user enters the system, you can see two processors in the system's Device Manager, which means that hyper-Threading technology has been successfully opened.

Second, system settings optimize the CPU

1, adjust the priority level of the program

In Windows systems, there are few optimizations for CPU, and you can optimize the CPU by setting the CPU priority level. Applications within Windows 2000/xp are divided into 32 levels (0~31), typically between 0~15 levels. By default, programs have a priority of 8, or "standard." In some cases, the priority of some unimportant processes can be lowered, which can improve CPU performance.

To set the CPU priority, you can do the following:

Step 1 Press Ctrl+alt+del to open the Windows Task Manager window.

Step 2 to select the program you want to set priority, click the right mouse button, select the "Set priority" → "low" command in the pop-up shortcut menu to reduce the level of the program.

2. Optimize processor level Two cache capacity

In Windows XP, you can set the level two cache capacity in the registry to speed up system operation. The method is as follows:

Step 1 first opens the registry and finds the following branch: "Hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemorymanagement".

Step 2 Select the "Secondleveldatacache" under it, the user based on their own processor settings, such as Athlon XP is "", P4northwood is "512".
