The AM4 socket is wired to 4 DDR4 DIMM slots, supporting as much as 64 GB of memory; two PCI-Categorical 3.0 x16 slots (x16/NC or x8/x8), and one of many two M.2 PCIe slots. Storage connectivity consists of two M.2 PCIe slots, the topmost slot is 32 Gbps, and M.2-22110, whereas the underside slot is 16 Gbps; and six SATA 6 Gbps ports. USB connectivity consists of ten USB 3.0 ports (six on the rear panel, 4 by headers), and two USB 3.1 gen 2 ports (together with one type-C port), on the rear panel. 8-channel onboard audio with a mid-range CODEC, and gigabit Ethernet with an Intel i219-V controller, make for the remainder of the 2. The Fatal1ty X470 Gaming K4 is barely higher endowed than the X470 Master SLI, in that includes a barely extra upscale onboard audio resolution (most likely ALC1220 vs. ALC892), Inventive SoundBlaster Cinema DSP, RGB LEDs in even the rear I/O shroud, and Fatal1ty Mouse Port (specialised USB port with supposedly decrease latency). The 2 might be priced beneath $150.
