AsRock SIENAD8UD3 Deep Micro-ATX Single-Socket SP6 Server Motherboard

Overview

The AsRock SIENAD8UD3 is a deep micro-ATX server motherboard built around a single SP6 (LGA) processor socket. SIENAD8UD3 targets integrators building compact rack or tower server nodes where a full-size ATX or E-ATX board won't fit the chassis budget but a single-socket platform is still the right call. At 9.60 x 10.50 in, the deep micro-ATX footprint fits shorter-depth rack chassis and dense server rooms where board real estate is at a premium.

Key Features

• Single Socket SP6 (LGA): A dedicated single-processor platform — the right architecture when you need server-class compute in a node that doesn't require dual-socket scaling, keeping power draw and chassis cost down versus a 2P build.
• Deep Micro-ATX Form Factor (9.60 x 10.50 in): Smaller footprint than standard ATX or E-ATX server boards, which matters when you're racking multiple nodes and every inch of chassis depth counts.
• 3.75 lb Board Weight: Useful when calculating shipping costs and rack payload budgets across multi-node deployments.

Integration & Compatibility

As a bare motherboard, the SIENAD8UD3 integrates into any chassis sized for deep micro-ATX boards with SP6 socket support. Confirm chassis standoff layout and I/O shield compatibility before ordering, since deep micro-ATX boards don't always match standard micro-ATX mounting holes. Country of origin is China (CN) for import/compliance documentation on government or regulated builds.

Marty Allison

The SIENAD8UD3 is a single-socket SP6 board in a deep micro-ATX footprint — 9.60 x 10.50 in, 3.75 lb. That's the full spec picture available on this SKU right now, so I'll speak to what I can verify rather than pad it out.

Technical Highlights:

• Single SP6 Socket: Server-class single-socket platform — right-sized for nodes that don't need dual-socket headroom.
• 9.60 x 10.50 in Deep Micro-ATX: Fits shorter-depth chassis than standard ATX server boards.
• 3.75 lb: Factor this into rack payload and shipping calculations for multi-node builds.

Deployment Considerations:

• Verify chassis standoff and I/O shield layout against deep micro-ATX dimensions before ordering — it's not a drop-in swap for standard micro-ATX.
• Full processor support, memory configuration, and expansion slot detail aren't published here — get those from AsRock's own documentation before finalizing a build-of-materials.

Reach for the SIENAD8UD3 when you're racking single-socket SP6 nodes in a chassis that can't accommodate a full ATX server board footprint.
