Our take on the ASRock Rack SIENAD8-2L2T AMD EPYC 8004 ATX Motherboard

The ASRock Rack SIENAD8-2L2T is an ATX server board built around AMD's EPYC 8004 series (Socket SP6) with the SoC chipset. It stands out for its dense PCIe 5.0 layout: three x16 slots with CXL 1.1 support, one more x16 and one x8, plus two MCIO x8 and two M.2 x4 links for NVMe. Eight DDR5 ECC RDIMM slots at 4800 MHz and dual Intel X710 10G LAN with a dedicated management port make it a compact single-socket platform for storage and networking builds. It suits homelab and small-business servers that want EPYC 8004 efficiency in a standard ATX case, where rivals often trade PCIe lanes or 10G networking for a smaller footprint.

Pros
  • Five PCIe 5.0 slots, three with CXL 1.1 support
  • Dual 10G Intel X710 plus dual GbE and dedicated management LAN
  • Eight DDR5 ECC RDIMM slots at 4800 MHz
  • Two MCIO x8 and two M.2 x4 PCIe 5.0 storage links
  • Standard ATX form factor with six fan headers
  • ASPEED AST2600 BMC with UID button
Cons
  • EPYC 8004 SP6 only; no EPYC 9004 support
  • 96GB maximum per DIMM slot limits total memory
  • No onboard SATA ports listed; storage relies on MCIO, M.2 or add-in cards
  • ATX layout leaves less room for expansion than larger server boards
  • 4-pin ATX PSU signal needs the included 24-pin adapter cable

Questions and answers

Which CPUs does this board support?
AMD EPYC 8004 series processors on Socket SP6. It does not take EPYC 9004 or older EPYC generations.
How much memory can it hold?
Eight DDR5 ECC RDIMM slots at 4800 MHz, up to 96GB per DIMM slot. That caps total capacity below boards that accept larger RDIMMs.
How many NVMe drives can I connect directly?
Two M.2 22110/2280 slots at PCIe 5.0 x4 and two MCIO connectors at PCIe 5.0 x8. More drives need an add-in card in a PCIe slot.
What networking is built in?
Two Intel X710-AT2 10G ports, two Intel I210 GbE ports and a Realtek RTL8211F dedicated management port for the BMC.
Does it fit a standard ATX case?
Yes, it is ATX. It uses a 4-pin ATX PSU signal with a 24-pin adapter cable plus two 8-pin 12V connectors, so check your PSU cabling.
What is CXL 1.1 support for?
Three of the x16 slots support CXL 1.1, letting you attach CXL memory or accelerator devices alongside standard PCIe cards.
