  • M.2 22110 NVMe PCIe 3.0 x4 plus M.2 2280 SATA 3.0 for fast storage
  • Ten SATA 3.0 ports plus four SATA 3.0 via SSATA give extensive drive connectivity
  • Dual Gigabit Ethernet and 7.1-channel audio built in for networking and sound

Dual Xeon E5-2678 v3 workstation board

The HUANANZHI X99 T8D pairs two 12-core Xeon E5-2678 v3 processors at 2.5 GHz on a single LGA 2011-3 platform. It targets users who need 24 threads for rendering, virtualization or scientific workloads without moving to a newer socket. The C612-series chipset and 12-phase power delivery support the dual-CPU configuration on an E-ATX PCB.

Upgrade from single-socket X99

Moving from a single E5 v3 CPU to this dual-socket kit doubles thread count and memory channels while keeping the same DDR3 investment. The jump is worth it when your current board limits you to 8 DIMM slots or a single PCIe 3.0 x16 slot and you need the extra 3*PCIe 3.0 x16 plus M.2 NVMe and SATA expansion. The board ships with a randomly selected C612-series chipset variant.

Installation notes for experienced builders

The E-ATX dimensions of 300*320 mm require a compatible chassis and careful alignment of the 24-pin plus dual 8-pin power connectors. Six fan headers and front-panel USB 2.0, USB 3.0 and audio pins follow standard pinouts but density is high. Common issues include mixing registered and unregistered DDR3 across the eight slots, exceeding 32 GB per DIMM, and confusing the two M.2 slots — one is NVMe PCIe 3.0 x4, the other shares a SATA signal.

Questions about this item

Will the E-ATX board measuring 300 by 320 millimetres fit in my case?

The board uses the E-ATX form factor at 300 by 320 millimetres so verify your case supports that size before purchase.

What is the most common mistake when installing the dual 12-core Xeon E5-2678 v3 processors?

Builders often forget the second 8-pin CPU power connector leaving one socket unpowered and the system fails to post.

When will the 1600 or 1866 MHz DDR3 modules need replacement?

DDR3 memory has no fixed lifespan; replace modules only if errors appear or capacity becomes insufficient.
