## Long description

ASRock EC266D4U is a micro ATX server and workstation motherboard based on the Intel C266 chipset with an LGA 1700 socket. It supports Intel® Xeon® processors and integrates an Aspeed AST2600 onboard graphics controller. The board provides four DDR5 DIMM slots with ECC support for up to 32 GB memory at up to 4400 MHz, eight SATA III ports and one M.2 slot, making it suitable for compact server, storage or workstation configurations.
Advantages
The motherboard combines server‑grade features in a compact micro ATX form factor: support for Intel Xeon processors on LGA 1700, ECC DDR5 memory across four DIMM slots, a wide set of storage interfaces including eight SATA III ports and an M.2 slot, and multiple PCIe slots including a PCIe Gen5 x16. Integrated Aspeed AST2600 graphics and dual Gigabit Ethernet ports provide basic remote management and reliable network connectivity. TPM connector and comprehensive I/O (USB, serial, VGA) support typical server and workstation requirements.
Suitable for
Compact server builds (file, application, or domain controller)
Storage appliances and NAS systems requiring multiple SATA devices
Workstations for light to moderate professional workloads
Embedded or industrial systems needing extended temperature and humidity ranges

How to use
Install the ASRock EC266D4U into a compatible micro ATX chassis and connect a compatible LGA 1700 Intel Xeon processor following the processor and heatsink manufacturer instructions. Populate DDR5 DIMM slots with ECC memory modules up to the supported capacity and voltage. Connect storage devices to the SATA III ports or the M.2 slot, and attach power via the 24‑pin ATX connector (and the 4‑pin Molex if required by peripherals). Configure BIOS settings (AMI) for boot order, memory and ECC options, and enable ACPI/SMBIOS features as needed.
Usage recommendations
For reliable server or workstation operation, use validated ECC DDR5 modules within the supported frequency and voltage, ensure adequate cooling for the chosen CPU, and keep BIOS firmware up to date. Use the dual LAN ports for redundant or segmented network setups and reserve the M.2 and OCuLink lanes for high‑performance NVMe storage where required.
