Dual LGA 2011 server board

The HUANANZHI X79 16D is an E-ATX motherboard built for dual Intel Xeon processors in LGA 2011 sockets. It targets builders assembling high-core-count workstations or render nodes that need massive memory capacity in a single chassis. The 12-layer PCB and 7+7 phase power delivery are engineered for sustained multi-socket loads.

16 DDR3 slots define capacity

Sixteen DDR3 DIMM slots support registered ECC, non-ECC or standard ECC modules at 1866, 1600, 1333 or 1066 MHz. Dual-channel architecture means memory must be populated in matched pairs per processor to reach rated bandwidth. Maximum supported capacity is 16 x 32 GB.

Handles big memory jobs, limited elsewhere

The board comfortably handles workloads that scale with core count and memory footprint such as virtualization hosts, offline rendering or scientific computing. It runs out of modern I/O headroom with only two SATA 3.0 ports, a single USB 3.0 header and PCIe 3.0 as the fastest expansion link.

Questions about this item

What does the 16 DDR3 slot count mean for total memory in a real build?

The board provides 16 DDR3 slots and each slot accepts modules up to 32 GB, allowing very large memory configurations when fully populated with compatible sticks

What does the PCI Express 4.0 x16 slot actually cap in practice?

One PCI Express 4.0 x16 slot is present alongside three PCI Express 3.0 x16 and three PCI Express 2.0 x16 slots, so the fastest link runs at 4.0 speeds while the others operate at their respective generation limits

What does the 12.3 by 13.4 inch E-ATX size need to fit in a case?

The board measures 305 mm by 330 mm and uses the E-ATX form factor, so it requires a chassis that explicitly supports E-ATX motherboards and has matching standoff positions
