Now that mini-PCs from companies such as ASROCK, ASUS and Zotac are catching up, SO-DIMM overclocking is something that would be interesting to see. G.SKILL did that using ASROCK M8 Barebone system.
G.SKILL managed to do just that, as they were able to overclock its ripjaws SO-DIMM 1.35V C11 2133 MHz to 2400 MHz 12-14-14-25 @ 1.35v.
ASROCK M8 is a barebone PC made for 4th Gen Intel series processors and uses Intel Z87 chipset. The system allows installation a single dual-slot video card with maximum dimension support of up to 290mm x 137mm x 43.5mm with up to TDP support of 200w. The unit also has 802.11 ac+ Bluetooth v4.0 support. M8 barebone system only includes a chassis, a 450w power supply, mini-ITX motherboard, fans and an optical disk drive. The rest of the components such as processors, memory kits and storage drive needs to purchased separately.
