The ASRock FM2A85X Extreme4-M uses the AMD Socket FM2 CPU socket. Any compatible AMD CPU will have the same socket entry. It uses the DDR3 memory type, with maximum speeds of up to 2400 MHz, and 4 DDR3 slots allowing for a maximum total of 64 GB RAM.
The Micro-ATX ASRock FM2A85X Extreme4-M should fit into all ATX cases, but its smaller size allows you to downsize your system build as a whole. Its size comes at the cost of features, so there are likely to be far fewer connections and expansion options available than in a larger motherboard.
The ASRock FM2A85X Extreme4-M has 7 SATA 3.0 hard drive slots. These allow for theoretical data transfer speeds of up to 6GB/s, as opposed to the 3GB/s of SATA 2.0. Generally speaking, only high performance hard drives, specifically solid-state drives, will be able to take advantage of the bandwidth potential of SATA 3.0 ports, though it is backwards compatible, so you do not have to take advantage.
The ASRock FM2A85X Extreme4-M supports onboard graphics. This allows for integrated graphics when paired with a compatible CPU that supports them. Integrated graphics are a cheap alternative to using a graphics card, but should be avoided when frequently using modern applications or games that require intense graphical processing. There are 2 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of PCIe v2.x, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the ASRock FM2A85X Extreme4-M's PCIe v2.x. The ASRock FM2A85X Extreme4-M supports up to 4 AMD Crossfire connected graphics cards for improved overall graphical performance at the cost of multiplied graphics-based power consumption as well as the price of the cards themselves. Nvidia SLI is not supported.
The ASRock FM2A85X Extreme4-M has 10 USB 2.0 slots and 4 USB 3.0 slots. USB 3.0 slots are theoretically capable of data transfer speeds of up to 5 Gbit/s, which is over 10 times faster than the USB 2.0 top speed of 480 Mbit/s. Although USB 2.0 slots alone currently serve as well as ever, an upgrade would better future-proof your system as more USB 3.0 compatible peripherals emerge. USB 3.0 is also backwards compatible with USB 2.0, which means you do not even have to use the newer slot functionality if you do not wish to.
