ASRock engineered the EPC612D4I, a new server-grade motherboard that squeezes four DDR4 sO-DIMM memory slots into a Mini-ITX form factor! Called the EPC612D4I, this motherboard uses the Intel C612 server chipset and supports LGA2011v3 processors.
There are no CPU overclocking features, because the board's driven by an Intel C612 chipset. The lone expansion slot is a PCI-Express 3.0 x16. It even comes with a basic onboard video, driven by an ASPEED AST2400 remote management chipset, which gives display output by D-Sub, and supports resolutions of up to 2048 x 1536. This chip is wired to its own dedicated GbE connection, while two other GbE connections are given out by Intel i210 and i217LM controllers, wired to the chipset's MAC. Storage connectivity includes four SATA 6 Gb/s ports. The board comes with official support and drivers for all its onboard devices, for Windows 2012 R2/2008 R2 SP1, SuSE Server 11 SP3, RHEL 6.5, CentOS 6.5, Fedora 19, Ubuntu 12.10, and FreeBSD 9.2.
The downside perhaps is that as this is designed for servers, it's expected to be pretty expensive and retail availability of the smaller DDR4 SO-DIMM memory is very limited.
