ASRock unveiled its first socket FM2+ motherboards, ready for the upcoming A-Series "Kaveri" APUs, and backwards-compatible with A-Series "Richland" and "Trinity" ones. Among the most notable of ASRock's FM2+ products are the FM2A88X-Extreme6+ and the FM2A88M-Extreme4+. The former is a feature-rich ATX form-factor offering, while the latter isn't too far behind with its feature-set, albeit in the micro-ATX form-factor. The FM2A88X-Extreme6+ features a 10-phase VRM to power the APU socket, which is wired to four DDR3 DIMM slots, and two PCI-Express 3.0 x16 slots (electrical x8/x8 when both are populated). A third PCI-Express x16 is electrical gen 2.0 x4, and wired to the A88X FCH. Two each of PCI-Express 2.0 x1, and legacy PCI make for the rest of the expansion. Storage connectivity on the FM2A88X-Extreme6+ includes seven SATA 6 Gb/s ports, and one eSATA 6 Gb/s. Display connectivity includes dual-link DVI, DisplayPort 1.2, and possibly HDMI 2.0. 8-channel HD audio with optical SPDIF output, gigabit Ethernet, and six USB 3.0 ports. Moving on, the FM2A88M-Extreme4+ features a simpler 6-phase VRM for the APU socket, which is wired to four DDR3 DIMM slots, and a single PCI-Express 3.0 x16. The other long slot is electrical gen 2.0 x4. One each of PCI-Express 2.0 x1 and legacy PCI make for the rest of its expansion. Display connectivity includes dual-link DVI, D-Sub, and HDMI (2.0?). Four USB 3.0 ports, 8-channel HD audio, and gigabit Ethernet make for the rest of it.
