WMtec X99-8M Dual Xeon LGA2011-3 DDR4 M-ATX server motherboard

Dual Xeon server board

The WMtec X99-8M is an M-ATX motherboard built for dual Intel Xeon processors using the LGA2011-3 socket. It targets system integrators and enthusiasts assembling multi-threaded workstations or small-footprint servers that need registered or non-ECC DDR4 memory. Two DIMM slots support speeds of 2400, 2133, 1866 and 1600 MT/s with a peak capacity of 32Gx2. Onboard networking uses a Gigabit Ethernet controller and audio relies on the ALC662 5.1 channel codec.

Upgrade from single-socket platforms

This board replaces single-socket X99 or consumer ATX boards when a workload scales beyond one CPU and the chassis can accept an M-ATX form factor. The jump is worth it for render farms, virtualization hosts or database nodes that benefit from doubled core counts and quad-channel memory architecture across two processors. Builders staying with a single Xeon or moving to newer socket generations will not use the second socket or the DDR42 channel layout. The 6 phase power delivery and 8-layer PCB are sized for the dual-CPU power envelope.

Straightforward M-ATX install

The 237x180 mm M-ATX layout fits standard mounting holes and aligns with typical standoff patterns. One PCI-E 3.0 16X slot and two PCI-E 1X slots handle GPU or add-in cards while four SATA 3.0 ports and an M.2 NVME interface cover storage. Six USB 3.0 and six USB 2.0 headers provide front-panel connectivity. Common issues include forgetting the 500w minimum power supply requirement, neglecting to install the CMOS battery after shipment, and exceeding the two-slot memory limit when planning capacity.
