V-Link Data 2X Support

Common Options : Enabled, Disabled

Quick Review

In VIA chipsets, the IDE/SATA controller (known as the VIA DriveStation) is linked to the south bridge chip using a dedicated V-Link bus that offers twice as much bandwidth as the PCI bus. However, there have been reports of hard drive data corruption as well as boot failures with some hard drives.

This is where V-Link Data 2X Support comes in. The BIOS feature controls the operation of the V-Link bus between the VIA DriveStation and the south bridge chip. It is slaved to the Serial ATA Controller BIOS feature. If the Serial ATA Controller BIOS feature is disabled, this BIOS feature will be grayed out.

When enabled, the V-Link bus connecting the VIA DriveStation to the south bridge chip will run at full speed, delivering 266MB/s of bandwidth.

When disabled, the V-Link bus connecting the VIA DriveStation to the south bridge chip will run at half speed, delivering 133MB/s of bandwidth.

It is recommended that you enable this BIOS feature for maximum performance from storage devices attached to the VIA DriveStation. However, if you experience data corruption or boot problems, disable this BIOS feature.
