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.

Questions about this item

How do I mount this 13.0" by 9.5" EATX board and which standoff pattern avoids shorts?

Use all nine mounting holes in the standard EATX layout; install metal standoffs only where the board has pads, then tighten screws evenly to prevent flex.

What component will need replacement first during long-term operation?

The onboard ES1000 graphics controller with 32 MB memory is soldered and not serviceable; plan for board replacement if video fails.

Which limit appears first when both Xeon sockets run sustained 100% load?

The 48 GB memory ceiling across six slots is reached before the three PCI Express x8 expansion slots saturate bandwidth.
