ASRock brings two new Socket FM2 motherboards to the table; the regular ATX FM2A85X Extreme4 and the Micro-ATX FM2A85X Extreme4-M. The FM2A85X Extreme4 is basically a cut-back version of the FM2A85X, it uses simple 6-phase VRM and offers four DDR3-1866 memory slots (max 64GB) and one PCI Express 2.0 x16 slot. It also has a PCIe 2.0 x4 slot, two PCIe 2.0 x1 slots, three legacy PCI slots, seven SATA 6Gbps ports (one assigned as eSATA), four USB 3.0 ports, Gigabit Ethernet, 8-channel audio and HDMI/DVI/VGA display outputs.
The Micro-ATX model is a compressed version of the FM2A85X Extreme 4:
Moving on, the FM2A85X Extreme4-M is a compressed variant of the FM2A85X Extreme4, which features an expansion slot layout of one PCI-Express 2.0 x16 wired to the APU, a PCI-Express 2.0 x4 (physical x16) wired to the FCH, and one each of PCI-Express 2.0 x1 and legacy PCI. Much like the FM2A85X Extreme4, its display connectivity features DVI, D-Sub, and HDMI; seven out of eight SATA 6 Gb/s ports are internal, with an eSATA port; gigabit Ethernet and 8-channel HD audio make for the rest of the connectivity.
Pricing is anticipated to be in the $90 to $110 range.
