Server Motherboard for Xeon E and Core i3

The ASUS P11C-X is an ATX server motherboard built on the Intel C242 chipset with an LGA1151 socket. It supports Intel Xeon E-2100 and E-2200 series processors as well as 8th and 9th generation Core i3, Pentium and Celeron CPUs up to 95W TDP. The board targets small to mid-size businesses needing a cost-effective platform for web, file, mail or storage servers and entry-level workstations.

Straightforward ATX Install with Rack Focus

Installation follows standard ATX 12 by 9.6 inch mounting points so it fits regular chassis and rack enclosures. The CPU and memory are positioned for maximum cooling efficiency in rack environments which helps thermal performance. Builders must use DDR4 2666 or 2400 UDIMMs in the four 288pin slots and should verify ECC or non-ECC compatibility with their chosen processor. Dual M.2 slots accept drives up to 22110 length for both PCIe and SATA interfaces.

128GB DDR4 Capacity Decides Fit

The four memory slots support up to 128GB of DDR4 2666 dual channel memory which is the key specification for memory-intensive server workloads. This capacity ceiling determines whether the board suits virtualization hosts, database servers or high-density storage nodes. Storage expandability includes 6 SATA 6Gb/s ports with RAID 0, 1, 5, 10 and two M.2 slots with RAID 0/1 while dual Intel Gigabit LAN (I219LM and I210AT) provides teaming support.

Questions about this item

How can I confirm the ASpeed AST2510 video chipset is active after first boot?

Connect a monitor to the VGA port; the ASpeed AST2510 with 64MB VRAM will display POST output and BIOS screens without any discrete graphics card installed.

What comes in the box and what must I source separately?

The board ships with an I/O shield, SATA cables and documentation; you must supply an LGA1151 CPU up to 95W, DDR4 2666 UDIMMs (ECC or non-ECC), M.2 drives up to 22110 length and a standard ATX power supply.

Should I choose the 64GB or 128GB memory limit for my build?

The board has four 288-pin DDR4 slots supporting dual-channel operation; populate all four slots with 32GB modules to reach the 128GB ceiling, or use 16GB modules for a 64GB configuration.
