ASRock is ready with its premium motherboard based on the AMD 870 + SB850 chipset, the ASRock 870 Extreme3. Either the company seems to have jumped the specifications of the 870 by adding external PCI-Express lane switching that gives it proper CrossFire capability, or that the 870 will indeed support 2-way CrossFire with its lone PCI-Express 2.0 x16 link split into two x8 links between the two cards, leaving no room for a "890X" chipset. The 870 Extreme3 supports socket AM3 processors with a 4+1 phase VRM that can take 140W TDP processors. It will support upcoming Phenom II X6 and Phenom II X4 T series processors. It integrates ASRock's proprietary UCC chip that unlocks disabled cores on certain processors.

The board is advertised to support DDR3-1800 MHz memory by overclocking. Expansion slots include two each of PCI-Express 2.0 x16 (electrical x8, when both are populated), PCI-E x1, and PCI. The SB850 southbridge gives out five internal SATA 6 Gb/s ports, with one eSATA. Other connectivity features include 8 channel HD audio, a 2-port USB 3.0 controller, a number of USB 2.0 ports, FireWire, and gigabit Ethernet. Diagnostic LED display and onboard power and reset switches make for the rest of it. The ASRock 870 Extreme3 will retail a little later this month.
