At its displays at the ongoing CeBIT event, ASUS surprised many with a pair of Crosshair IV Series
motherboards showing a renewed interest at the very high-end of the AMD platform. Incidentally, the company is also preparing a mid-range motherboard based on the AMD 890FX chipset, the M4A89TD PRO. The new board builds entirely on what the chipset has to offer with a slight addition of a two-port USB 3.0 controller. The AM3 socket is powered by a 10-phase VRM, supporting 140W CPUs. It is wired to four DDR3 DIMM slots with its own 2-phase VRM.
The 890FX chipset gives out two PCI-Express 2.0 x16 full-bandwidth slots, other expansion slots include an open-ended PCI-E 1.1 x4, a PCI-E x1, and two PCI slots. All six SATA 6 Gb/s ports the SB850 southbridge gives out are internal, an additional JMicron controller gives out IDE and eSATA. The board boasts of ASUS' "Core Unlocker" switch which simplifies unlocking disabled physical cores on some dual, triple, and quad-core chips. Other features include 7.1 channel audio, gigabit Ethernet, and USB 3.0 for connectivity. The M4A89TD PRO should be released around the time when AMD unveils its latest processors.
