6th Generation Intel® Xeon® E3 / Core™ i7/i5/i3 & Celeron®
Mini-ITX Motherboard w/ Intel® CM236 PCH

6th Generation Intel® Xeon® E3 /Core™ i7 / i5 /i3 / Pentium® Celeron® QC/DC processors, up to 4GHz2x DDR4 SO-DIMM, Max. 32GB, ECC compatibleIntel® Processor integrated graphic device, supports DVI-D, HDMI and DisplayPortDual Intel® Gigabit LAN2x USB 2.0, 6x USB 3.0, 4x COM, 4x SATAIII2x Mini PCI-E slots, 1x mSATA, 1x PCI-E(16x)Watchdog timer, Digital I/O, iAMT (11.0), TPM (1.2), iSMART 3.0

The MI991 Mini-ITX motherboard is with a Socket H4 (LGA1151) socket and the Intel C236 chipset. System integrators can benefit from the MI991 equipped with space-saving compact configuration and rich I/O design for maximum flexibility.

IBASE MI991 supports up to three independent displays via Intel® HD Graphics: DVI-D, HDMI, and DisplayPort, as well as DDR4 32GB limitation on two memory slots. It uses the more expensive Intel i211 controller instead of Realtek controllers for the motherboard alongside the Intel chipset i219 NIC device. Friendly features also include eight USB, four serial ports, four SATA III as well as two Mini PCI-E, an mSATA and a PCI-E(16x) expansion slot.

Aside from the Intel® C236, the MI991 models are also offered with the Intel Q170 or H110 chipset with differences in NIC and SATA III configurations. The boards come standard with a watchdog timer and IBASE iSMART green technology featuring power on/off scheduling, power resume function, and intelligent OS recovery that reduces maintenance cost, enhances system stability and ensures long-term reliability.
