ASRock endows the X48TurboTwins-WiFi with a complete controller set typically expected of high-end motherboards, but differs from the norm by using a non-SATA add-in disk controller. Intel chipsets haven’t supported Ultra ATA devices since the P965, and ASRock would have likely left the board devoid of any add-in controller had this not been the case.
The X48TurboTwins-WiFi port panel provides PS/2 keyboard and mouse ports, coaxial and optical digital audio outputs, IEEE-1394 FireWire, six USB 2.0 ports, a single gigabit network port and six analog audio jacks. Two internal SATA to eSATA pass-through connections are also found here, but enabling these requires some very messy internal cabling.
ASRock chose JMicron’s JMB368 Ultra-ATA controller, rather than one that supports both Ultra-ATA and SATA. It uses one of the chipset’s six unallocated PCI-Express pathways to provide optimal performance…typically to slow devices such as a DVD burner.
Realtek’s RTL8111C uses PCI-Express to provide full bi-directional bandwidth to a single Gigabit Ethernet port. The motherboard’s single PCI-Express x1 slot and two third-party controllers use up only three of the chipset’s six “spare” lanes.
ASRock uses VIA’s ancient 6308 series FireWire controller to provide two IEEE-1394 ports. At 133MB/s, its PCI interface is more than fast enough to provide full performance for two 50MB/s (400 megabit) connections.
ASRock is the only company we know of to use Realtek’s ALC890B audio codec, which the company rates at a respectable 110db signal-to-noise ratio.
ASRock continues to use the AW-GA800BT mini-USB card previously found in Asus WiFi products to provide 802.11g/b wireless networking. Realtek’s RTL8187L controller does the job nicely.
