Supermicro MBD-X8DTT-HIBQF server motherboard LGA-1366 5520 DDR3 12 slots 48 GB

SKU CH-AF5Q-9BMTH MPN MBD-X8DTT-HIBQF

Dual-socket server board with twelve DDR3 slots supporting up to 48 GB memory

  • Dual-socket Xeon support with Intel 5520 chipset
  • 12 DDR3 slots deliver up to 48 GB memory capacity
  • Four SATA 300 ports provide internal storage connectivity
  • Matrox G200Ew graphics controller handles basic display output
  • Two USB 2.0 ports enable peripheral connections

Dual-socket LGA-1366 server board

The Supermicro MBD-X8DTT-HIBQF+-B is a dual-processor server motherboard built around the Intel 5520 chipset. It accepts two Xeon dual-core CPUs in LGA-1366 sockets linked by a 6.40 GT/s QuickPath Interconnect. Onboard graphics come from a Matrox G200Ew controller and the board uses a proprietary form factor.

Suits legacy dual-socket rebuilds

This board fits technicians restoring or expanding older rack systems that require registered DDR3 memory and Serial ATA/300 storage. It provides twelve DIMM slots, four SATA interfaces and two USB 2.0 ports. Builders needing more than 48 GB of memory, faster storage interfaces, or a standard mounting pattern should look elsewhere.

Twelve DDR3 slots capped at 48 GB

The maximum memory supported is 48 GB spread across twelve slots, so each module is limited to 4 GB when fully populated. This ceiling decides whether the board can meet a given workload’s memory requirement.

Questions about this item

What proprietary form factor does this Supermicro MBD-X8DTT-HIBQF server motherboard use?

The board uses a proprietary form factor, so verify your chassis supports this exact layout before purchase.

How are the two Xeon processors installed in the dual LGA-1366 sockets, and what step is often missed?

Install both CPUs with matching stepping, then apply thermal paste evenly and torque the heatsink screws in a cross pattern to avoid uneven pressure.

When should the 48 GB DDR3 memory limit be reviewed for an upgrade?

Plan a memory review when workloads approach the 48 GB ceiling across the 12 slots, as the chipset cannot address more.
