ASRock has a reputation for delivering mini-ITX motherboards for Intel’s high-end desktop (HEDT) platform where other motherboard vendors dare not try. With X299 ASRock has done it again, this time with the X299E-ITX/ac, and this small-yet-mighty motherboard has a range of tricks up its sleeves.
Mini-ITX motherboards for a platform like X299, where the LGA2066 socket is so large, inevitably involves compromise even for the highly-skilled engineers that previously developed the ASRock X99E-ITX/ac motherboard. That compromise is by no means a bad thing because it facilitates innovation, experimental thinking and new approaches to the space constraints of the mini-ITX form factor.
ASRock’s innovation for its X299 mini-ITX motherboard is particularly fascinating – full quad channel memory support by opting for DDR4 SO-DIMM (laptop memory) rather than DDR4 DIMM (desktop memory). The X99 iteration of ASRock’s mini-ITX motherboard opted for two DDR4 DIMM slots as its memory solution which sacrificed the benefits of quad channel memory but retained the familiar DDR4 DIMM form factor.
ASRock has made plentiful use of “daughterboards”, secondary vertical PCBs, that have long been used by motherboard vendors on mini-ITX motherboards as a space-saving tactic since at least the introduction of the Z77 chipset in 2012. The ASUS P8Z77I-Deluxe is the first such mini-ITX motherboard that comes to mind that used a daughterboard in a mini-ITX form factor.
ASRock, though, has opted to use the daughterboards for connectivity like SATA and M.2 rather than the VRM solution, as has been typical in the past. As such ASRock is still able to offer triple M.2, six SATA ports, quad channel memory, dual Gigabit, Wi-Fi, USB 3.1 and more, all in a tidy mini-ITX form factor.
