ASRock Rack EPYC3101D4I-2T Server Motherboard - AMD Z790 Chipset - Socket - Mini ITX

Discover a compact, enterprise-grade motherboard built for dense server deployments that demand reliability, memory protection, and solid networking. The ASRock Rack EPYC3101D4I-2T blends a Mini ITX form factor with server-class capabilities, delivering EPYC processor support, a robust DDR4 memory platform, and dependable networking in a space-efficient blueprint. Designed for virtualization, edge computing, NAS/ storage appliances, and compact data-center builds, this board is engineered to optimize performance per watt while maintaining the resilience required in 24/7 operations. While the AMD Z790 chipset anchors the I/O efficiency and PCIe lane distribution, the platform remains focused on stability, memory integrity, and scalable memory options for growing workloads.

• Compact, dense design for scalable data centers: The Mini ITX form factor allows you to deploy server-grade performance in tight spaces—ideal for micro data centers, compact enclosures, or rack-dense installations where space and airflow are at a premium. This board enables IT teams to build reliable, low-profile server nodes without sacrificing essential features, making it a smart choice for virtualization clusters, edge computing, and home-lab environments that require enterprise-grade reliability in a smaller footprint.
• EPYC processor readiness for demanding workloads: Engineered to support AMD EPYC 3101 processors, this motherboard brings the computational power needed for virtualization, database workloads, container orchestration, and multi-user tasks. By pairing a capable EPYC CPU with ECC memory and a solid I/O foundation, you can achieve higher consolidation ratios, smoother virtualization performance, and more predictable latency under load—crucial for mission-critical applications and multi-tenant environments.
• Memory flexibility and reliability with ECC DDR4: The board provides 4 DIMM slots with support for up to 128 GB of DDR4 ECC memory. It accepts UDIMM, RDIMM, and LRDIMM modules, giving IT teams flexibility to mix module types for cost optimization or tiered memory configurations. Memory speeds reach up to 2666 MT/s, enabling solid bandwidth for virtual machines, databases, and file services while ECC protection helps guard against silent data corruption and minimizes downtime due to memory errors.
• Built-in Gigabit Ethernet for dependable connectivity: A reliable onboard network interface ensures steady data transfer and management access in server roles, NAS appliances, or edge devices. For deployments demanding higher bandwidth or redundancy, the platform typically supports expansion through add-in NICs or PCIe-based networking options, allowing you to tailor networking to your workload, whether that means more throughput, NIC teaming, or enhanced QoS for storage workloads.
• Strong I/O and chipset foundation with server-grade stability: The AMD Z790 chipset on this ASRock Rack board is selected to optimize peripheral throughput, PCIe lane distribution, and overall I/O performance. While designed to keep I/O predictable under heavy workloads, the platform also supports essential server features such as memory protection, consistent boot behavior, and scalable expansion potential, making it suitable for virtualization nodes, storage controllers, and compact server appliances that require dependable, long-term operation.
