Real-time customs processing times

Win7 turns on Real-time customs processing timesAHCI to improve performance! AHCI (Advanced Host Controller Interface) is a new generation of technology for SATA (Serial ATA) hard disk interface.It can improve the read and write performance of the SATA hard disk, and improve the data transmission rate and system response speed. The Win7 system does not turn on AHCI by default, but turning on AHCI can improve system performance. This article will introduce how to turn on AHCI in Win7. I. Things you need to know before turning on AHCI. In the Win7 system, you need to back up before turning on AHCI mode to prevent operational errors. At the same time, after starting the AHCI mode, the original IDE mode will not be able to start, otherwise errors such as blue screen will occur. Therefore, please make sure that you have a certain understanding of the AHCI mode or consult a professional before operating. II. Why turn on the AHCI mode? The AHCI mode is more advanced than the IDE mode, so it can improve the performance of the SATA hard disk.First of all, the AHCI mode can make the hard disk self-diagnose when the system starts, so as to improve performance. Secondly, AHCI mode can provide space and system support. AFTER WIN7 TURNS ON AHCI, YOU CAN USE THE TRIM COMMAND TO OPTIMIZE THE SSD HARD DISK AND IMPROVE THE LONG-TERM STABILITY OF THE HARD DISK. Finally, the AHCI mode can also make NCQ (Native Command Queuing) effective, so as to optimize the ability of multitasking parallel processing, improve the reading and writing efficiency of the hard disk, and make the system more stable. III. Operation steps of Win7 1. Before starting the backup data operation, you need to back up the data in the computer. If your system disk is a SATA hard disk and AHCI is not turned on, you need to back up the data to other hard disks or USB flash drives and other storage media before operation.2. Set the registry to open "Run" (which can be opened through the keyboard shortcut "Win+R"), enter the "regedit" command, and enter the registry editor. Locate the "Start" key value under the path of "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Msahci" and modify its value to "0" (the original value should be " 3"). 3. Turn on the AHCI mode and set it in the BIOS. The AHCI mode is not turned on by default, only the IDE mode. Therefore, you need to turn on the AHCI mode in the BIOS first. When powering on, press the DEL key or F2 key to enter the BIOS interface, find the SATA configuration, and select AHCI mode in SATA mode.The setting interface may be different for different BIOS. 4. Restart the computer. After the above operation is completed, you need to restart the computer to take effect. After the system restarts, the SATA hard disk with AHCI turned on will be recognized, and the response speed of the system when transmitting data will also be improved. IV. Notes 1. Before setting up the BIOS, you need to know the model and motherboard model of your computer to avoid unexpected losses during operation. 2. Before turning on the AHCI mode, you need to back up the data to prevent data loss. 3. After turning on the AHCI mode, if you want to restore the IDE mode, you need to reinstall the Windows system. In a word, turning on the AHCI mode can improve the performance and running speed of the SATA hard disk and make the system respond faster, but you must back up the data before operation to prevent unnecessary losses caused by operation errors.According to this operation, the performance of your computer will be significantly improved.
