After installing Win7, turn on AHC mode, the system flies more fierce

AHCI describes a PCI-like device whose primary role is to play an interface between system memory and Serial ATA devices, and it is common across different operating systems and hardware. It is understood that the use of AHCI mode in the motherboard BIOS in XP will make the system run faster, then, can it be achieved in windows7? After reading this article, you may get the answer. It is reported that many people It is believed that the opening of AHCI is equivalent to adding a power motor, so that it does not have to run so hard. Friends who want to open AHCI must be supported by the motherboard.

Many friends ask how to open AHC, I will simply talk about it. At the same time, click DEL to enter the BIOS. In the Advanced option, adjust the default IDE in SATA controller Mode to AHCI. (Of course, the BIOS of different motherboards may be different. You should look at the options about ACHI, below. To give a simple example)

AHCI technology introduction:

In the AHCI 1.0 specification, Intel introduced the NCQ (Native Command Queue) function and hot plug technology. After receiving the read/write command, the hard disk supporting NCQ technology will reorder the access address according to the instruction, which reduces the reading time, makes the data transmission more efficient, and effectively extends the service life of the hard disk.

AHCI, the full name of Serial ATA Advanced Host Controller Interface, is an interface standard jointly developed by many companies under the guidance of Intel. Its R&D team members mainly include Intel. Well-known companies such as AMD, Dell, Marvell, Maxtor, Microsoft, Red Hat, Seagate and StorageGear. AHCI describes a PCI-like device whose primary role is to play an interface between system memory and Serial ATA devices, and it is common across different operating systems and hardware.

After receiving the read/write command, the hard disk supporting NCQ technology will reorder the access address according to the instruction, which reduces the reading time, makes the data transmission more efficient, and effectively extends the service life of the hard disk.

AHCI technology requires both hard disk and motherboard support. For the hard disk, there is currently no product that fully supports AHCI 1.0, but some hard disks already support the NCQ function, which can be implemented with the motherboard supporting AHCI.

On the motherboard side, in the BIOS of some Lenovo models, you can see the SATA working mode and AHCI function. When the SATA mode is set to Enhanced, AHCI can select Enable or Disable; when SATA mode When set to Compatible, the AHCI option is not visible (default Disable). In summary, there are three combinations of possible combinations of these two settings.

Hard disk AHCI mode is a very strange term for many ordinary users, but with the current development of hard disk products faster and faster, AHCI has become a must-have for everyone.
