Supermicro X7DCU dual LGA 771 Intel motherboard

Dual LGA 771 server board

The Supermicro X7DCU is a dual-socket Intel motherboard built for Xeon dual-core and quad-core processors. It targets system builders assembling rackmount or workstation servers that need two physical CPUs in a single chassis. The board uses the Intel 5100 chipset and provides six memory slots with a 48 GB maximum capacity. Onboard ES1000 graphics supply 32 MB of video memory for basic display output.

Thermals power and noise

The 13.0 by 9.5 inch form factor fits standard server enclosures and allows airflow paths designed for dual-processor thermal loads. Enhanced SpeedStep Technology lets each Xeon reduce frequency and voltage during light workloads, lowering power draw and fan speed when the system is idle. With only two onboard USB ports and a single IDE interface, the platform keeps peripheral overhead minimal so the cooling subsystem can focus on the CPU sockets.

Included accessories and software

The package delivers a server-class foundation without bundled RAID controllers, advanced management modules or proprietary utilities. Builders must supply their own memory modules, storage controllers and operating-system licences to complete the platform. This approach keeps the bill of materials transparent for integrators who prefer to select each component individually rather than pay for pre-installed software they may replace.
