Supermicro’s X99 chipset motherboard!

Supermicro is a known name within the server business, but it also has some consumer-class motherboards. One of them is the C7X99-OCE, an ATX motherboard for the LGA 2011-3 processors Haswell-E and Broadwell-E(?) SKUs. While these aren’t the new motherboard variants, it reminds me of the Gigabyte X99-UD4– a good X99 chipset motherboard with good layout options. There are some additional features, such as overclocking buttons and the debug LEDs, dual LANs and probably a few more. The Supermicro C7X99-OCE was around for a while (a year?) but I am curious to see how good the motherboard is. Intel X99 chipset is still around reinvigorated by the Broadwell-E lineup.

Supermicro has two variants of the X99 OC boards. The OCE-F has a VGA output for IPMI. But the OCE has ten SATA III ports. There are a couple of more differences but essentially is the same.


Supermicro pitches its six key selling points- eight layered PCB (many motherboards have six), top grade ceramic chip capacitors, Nippon Chemi-con NPCAP solid caps, 15u gold plated socket pins and slots, a combination of digital PWMs, DrMOS and ferrite chokes followed by more components to reduce noise and boost reliability.

The packaging and accessories are nothing more than bare essentials. While Supermicro did provide a quickstart guide, the absence of a user’s manual is the first I’ve seen in a motherboard. Supermicro does have a PDF copy on its website. The rear I/O shield as the standard cushioning behind it, but the I/O holes are not punched out. Supermicro provides six cables, but none of those are with right angled connectors.

The Supermicro C7X99-OCE motherboard is a standard ATX design with 8 DDR4 DIMM Slots, totaling the support up to 128GB 3300MHz. There are a total of 10 SATA III ports, of which 4 are sSATA. The motherboard has two gigabit ports using Intel i210-AT, total six USB 3.0 ports including the header. While it doesn’t have USB 3.0 Gen 2 Type A and C, SuperMicro could have provided more USB 3.0 in the rear panel.

There is a single keyboard/mouse PS/2 port, a TPM header and a serial port header. It only has a single BIOS EEPROM but it does have a chassis intrusion header which is not seen typically in consumer-class motherboards.  There a total five fan headers out of which 1 of them is labeled for CPU.
