Closely trailing last week's news of ASRock designing the P55 Extreme4 motherboard that has two sets of 2-port USB 3.0 and SATA 6 Gb/s controllers, comes that of the 890FX-Deluxe4 and 890GX-Extreme4. As the names suggest, these motherboards will be based on the AMD 890FX and AMD 890GX chipsets, respectively, supporting socket AM3 processors. Unlike its P55-based counterpart, these boards feature two 2-port USB 3.0 controllers of which one gives out USB 3.0 front-panel header instead of two additional rear panel ports, and since the AMD SB850 southbridge already has a 6-port SATA 6 Gb/s RAID controller, there is only one additional 2-port SATA 6 Gb/s controller, upping the total number of 6 Gb/s ports to eight.

This apart, the 890FX-Deluxe4 and 890GX-Deluxe4 bear some resemblance to the 890FX-Deluxe3 and 890GX-Extreme3, respectively, in terms of board layout. The boards feature a 10-phase CPU VRM design, support ASRock Turbo UCC (gives Turbo boost to more than 3 cores on Phenom II X6), ASRock UCC (unlocks disabled cores on some X3, X2 processors), and memory ratio supported up to DDR3-1866 MHz by overclocking. The boards also support 3-way and 2-way ATI CrossFireX, and connectivity which includes 8+2 channel HD audio, gigabit Ethernet, and Firewire. Expect the new Extreme4 motherboards to reach stores in the coming few weeks.
