AsRock ALTRAD8UD-1L2T Single-Socket Deep Micro-ATX Server Motherboard

Overview

The AsRock ALTRAD8UD-1L2T is a single-socket deep micro-ATX server motherboard built around the LGA4926 platform, sized for compact rack and edge deployments where you still need full server-class I/O. At 12.35 x 13.60 inches, it's larger than a standard mATX footprint (hence "deep" mATX) but still fits shorter-depth rack chassis where a full ATX or SSI-EEB board won't. This is a bare board for integrators building or refreshing edge servers, video management hosts, or NVR back-ends that need dual 10GbE and single-socket simplicity rather than a dual-socket monster. The ALTRAD8UD-1L2T (often searched as ALTRAD8UD 1L2T) ships as a standalone board — plan your own CPU, memory, storage, and chassis around it.

Key Features

• Single-socket LGA4926 platform: targets Ampere Altra-class processors, giving you high core density without the board complexity, BIOS tuning headaches, and NUMA balancing overhead of a dual-socket design — a real advantage when you're provisioning a dedicated recording or analytics node and don't want to manage cross-socket memory locality.
• Dual 10GbE onboard networking (1L2T): two 10-gigabit ports out of the box means you can dedicate one link to camera/storage traffic and one to management or uplink without adding a NIC and burning a PCIe slot — meaningful on a deep mATX board where slot count is already tight.
• Deep Micro-ATX form factor (12.35 x 13.60 x 3.00 in): fits shorter-depth rack enclosures that can't accommodate full ATX or EEB boards, while still giving you more routing room than a standard mATX design for the extra networking and I/O this board carries.
• 3.31 lb board weight: confirms a full server-grade PCB with multi-layer routing for the 10GbE traces and power delivery a single-socket Altra-class CPU needs — worth noting when calculating shipping and chassis mounting hardware load.

Integration & Compatibility

Pair this board with a chassis rated for deep micro-ATX clearance — standard mATX cases built to the 9.6 x 9.6 in spec will not accommodate the 13.60 in depth. Because it's single-socket, cooling and power design is simpler than dual-socket alternatives in the same server motherboard family — worth comparing if your workload profile calls for more aggregate core count instead. If you're speccing this into a video surveillance backend, review a VMS architecture guide before finalizing chassis and drive layout, since recording throughput and retention windows drive both CPU and storage decisions. For camera-side infrastructure feeding into a server built on this board, see the IP camera and network video recorder categories, and pair the dual 10GbE ports with a managed PoE switch for camera uplink. AsRock's broader server and workstation motherboard line includes dual-socket and alternate networking configurations if this specific I/O mix doesn't match your build.

Frequently Asked Questions

Q: What CPU socket does the ALTRAD8UD-1L2T use?

A: It's a single-socket LGA4926 board designed for Ampere Altra-class server processors.

Q: How many network ports does the ALTRAD8UD-1L2T have?

A: Two onboard 10GbE ports, as indicated by the 1L2T designation.

Q: Will the ALTRAD8UD-1L2T fit a standard micro-ATX case?

A: No. At 12.35 x 13.60 inches it's a deep micro-ATX design, larger than the standard 9.6 x 9.6 in mATX footprint, so it needs a case or rack tray rated for the extra depth.

Q: What does the ALTRAD8UD-1L2T weigh?

A: 3.31 lb for the bare board.

Q: Where is the ALTRAD8UD-1L2T manufactured?

A: Country of origin is China (CN), per manufacturer data.

Eden Phillips

The ALTRAD8UD-1L2T crosses my desk whenever an integrator is building an edge recording or analytics node and doesn't want the complexity of a dual-socket board. Single LGA4926 socket, dual 10GbE onboard — that's a deliberate, focused spec set, not a kitchen-sink server board.

Technical Highlights:

• Single-socket LGA4926: one Ampere Altra-class CPU simplifies BIOS memory tuning and avoids NUMA-aware software requirements that dual-socket boards force onto your OS and application stack.
• Dual 10GbE (1L2T): two 10-gigabit ports let you segregate storage/camera ingest traffic from management traffic without eating a PCIe slot on add-in NICs.
• 12.35 x 13.60 x 3.00 in, 3.31 lb: deep mATX sizing gives you more routing real estate than standard mATX for the extra networking, while still fitting shorter-depth rack trays that won't take a full ATX board.

Deployment Considerations:

• Confirm your chassis or rack tray is rated for deep mATX (13.60 in depth) before ordering — a standard 9.6 x 9.6 in mATX case will not clear this board.
• This is a bare board — budget separately for an Ampere Altra-class CPU, ECC memory, and a compatible cooler rated for the LGA4926 socket.

I'd spec the ALTRAD8UD-1L2T for a single dedicated recording or edge-analytics server where dual 10GbE uplinks matter more than raw dual-socket core count — a compact NVR backend or edge inference box in a rack with limited depth.
