Windows 7 turns on AHCI to enhance hard disk performance system

Windows 7 tips

Today's computer systems, hard disk performance has become the biggest bottleneck affecting machine performance. In the high demand for components Windows7 system to optimize the hard disk will naturally become the object of opening the hard drive through AHCI mode, you can upgrade to some extent the performance of the hard disk.

According to information website Win7 news reported recently, Windows 7 in the performance of energy conservation concern by many people in the industry. Mindteck is engaged in embedded software development and consulting Dell Latitude E6500 battery services. The company recently released study shows that using the Windows 7 operating system than the old XP PC to save a large amount of energy costs, an average of 25% energy saving than the XP loss, equivalent to 30-55 per PC laptop battery per year can save dollars.

Thus see, Windows 7 compatible hardware than previous versions to upgrade the performance of many. Well, here is how we provide some Windows 7 system environment to further enhance the power endurance capacity of the reference suggestions:

Today's computer systems, hard disk performance has become the biggest bottleneck affecting machine performance. In the high demand for components Windows7 system to optimize the hard disk will naturally become the object of opening the hard drive through AHCI mode, you can upgrade to some extent the performance of the laptop battery hard disk.

Under normal circumstances, the hard drive in the BIOS by default for the native IDE mode in order to get the best compatibility. If this mode is installed Windows7, then change the hard drive in BIOS to AHCI mode, you can not access system, need to re-install system Caixing. Is there a way without reinstalling the system, open the hard disk on AHCI mode? Of course!

Tips: What is the hard disk AHCI mode?

Serial ATA AHCI is the acronym for senior master interface, which is dominated by Intel, a Dell Latitude E6500 battery technology that allows the storage driver to enable advanced SATA features such as Native Command Queuing (NCQ) and hot plug. Open AHCI SATA hard drive to play after the performance potential, in theory, increase about 30% of the hard disk read and write speed.

STEP1: After clicking the start menu, select the menu "Run" section. In the run part of the input box, type "regedit", press Enter to open the Registry Editor.

STEP2: Open the Registry Editor, the entry "HKEY_LOCAL_MACHINE \ System \ CurrentControl \ SetServicesMsahci" key. In the right window, double-click the name for the "Start" project, will pop up a dialog box to change the default parameters from 3 to 0. Click "OK" and save, restart the computer.

STEP3: Restart computer, enter BIOS, in "Integrated Peripherals" page, to "SATA RAID / AHCI Mode" changed to "AHCI" (names have different nuances of BIOS options).

Save the restart, after entering the system will automatically install the AHCI driver. After installation will be asked to reboot again, restart, hard disk AHCI mode opens.

Written in the last: hard drive change to AHCI mode, the system starts the velocity changes little. However, when making copies of large files, the speed from the original 60MB / S upgrade to 71MB / S, about 20% performance increase the laptop battery. Hard disk in the system score in Windwos7, also from the start of the 5.9 upgrade to 6.5 points. So hard to open AHCI, the effect is good.
