Black E-ATX server motherboard with dual LGA2011-3 sockets, eight DDR4 slots, two RAM sticks and a switch cable

YINGHUA

YINGHUA X99 Dual-Socket LGA2011-3 Server Motherboard + 2×DDR4 4GB 2666MHz RAM + Switch Cable

SKU CH-S3S1-4QXQP

Dual-socket LGA2011-3 server board with X99 chipset, eight DDR4 slots supporting 256 GB, eight SATA 2.0 ports, dual M.2 NVME, three PCIe x16 slots, dual 100 Mbps LAN.

  • CPU TypeIntel Atom
  • Dual LGA2011-3 sockets enable two CPUs
  • Eight DDR4 slots support up to 256 GB
  • Dual M.2 NVME plus eight SATA 2.0 ports
  • 12-phase power on 8-layer E-ATX PCB
  • Bundled 2×4 GB DDR4 2666 MHz RAM and switch cable

Dual LGA2011-3 Workstation Board

The YINGHUA X99 motherboard accepts two processors in LGA2011-3 sockets and ships with two 4 GB DDR4 2666 MHz modules and a switch cable. It targets builders assembling a multi-socket server or render node who want a tested foundation without sourcing memory separately.

Eight-Layer PCB With Twelve-Phase Power

An eight-layer PCB and twelve-phase power delivery feed both sockets from one 24-pin and two 8-pin connectors. Eight SATA 2.0 ports and two M.2 NVME slots handle storage, while three PCI Express x16 and two x1 slots provide expansion room for add-in cards.

Step Up From Single-Socket Boards

Moving from a single-socket platform doubles the core count available to heavily threaded workloads such as virtualization hosts or offline rendering. The jump makes sense when software scales across physical CPUs and the budget covers the extra processor and cooling.

Questions about this item

What does the dual M.2 NVMe interface cap in practice?

The two M.2 slots use the NVMe protocol, but the board only provides SATA 2.0 for its eight SATA ports, so NVMe speed depends on the CPU and chipset lanes.

What clearance and mounting pattern does the E-ATX 33 x 31 cm board need?

It requires an E-ATX compatible chassis with matching standoff holes and enough room for the 33 cm width and 31 cm depth.

How is the switch cable connected, and which header is often missed?

The included switch cable plugs into the front-panel header; the 24-pin and both 8-pin CPU power connectors must also be seated or the system will not post.
