SSI EEB motherboard KRPA-U16

AMD EPYC™AMDDDR4 SDRAM

Product Overview
AMD EPYC™ 7003 & 7002 LGA 4094 EEB server motherboard designed for high-density compute and storage-dense servers. Supports DDR4 3200 up to 16 DIMMs, multiple PCIe 4.0 links, M.2 and extensive NVMe/Oculink connectivity for low-latency storage and HPC deployments.

Key Features

• Supports AMD EPYC™ 7003 & 7002 Series processors with advanced I/O, memory and security features
• Multiple PCIe 4.0/3.0 lanes including a PCIe 4.0 x24 link (splittable to x16 + x8)
• Up to 16 DIMMs for up to 2 TB DDR4 3200 memory
• Up to 12 NVMe drives via Oculink (6 onboard Oculink ports via PCIe x4 + 6 via ASUS riser card)
• Dual onboard Gigabit LAN plus optional OCP 2.0 mezzanine card support for 100G or higher
• Out-of-band and in-band management with embedded ASMB9-iKVM and ASUS Control Center
• ASUS Thermal Radar 2.0 for multi-zone thermal monitoring and dynamic fan control

Performance & I/O
Optimized for high core-count workloads with 8-channel memory support and broad PCIe 4.0 lane availability. Includes multiple PCIe 4.0 links and a flexible x24 PCIe 4.0 link that can be split to x16 + x8 for additional NIC or storage expansion.

Ultrafast Connectivity
Dual embedded Gigabit Ethernet is standard. OCP 2.0 mezzanine card support enables 100G or higher interconnects for HPC and clustered environments when used with validated mezzanine cards.

Storage and NVMe
Designed for high throughput: up to 12 NVMe solutions via Oculink (six onboard + six via ASUS riser) and support for up to 16 SATA/SAS drives for flexible capacity and cost-performance configurations.

Onboard M.2
Includes M.2 with x4 PCIe 3.0 bandwidth (up to 32 Gbps) suitable for OS or application drives to accelerate boot and I/O tasks.

Management and iKVM
Embedded ASMB9-iKVM and ASUS Control Center provide comprehensive remote management: remote BIOS updates, fan control, standalone KVM, video recording and BSOD capture for diagnostics when the OS is down.

Exclusive Performance Technologies
ASUS Performance Boost technologies include:

• Core Optimizer — maximizes processor frequency for multi-core operations
• Engine Boost — automatic power acceleration with optimized voltage design
• Workload Presets — BIOS profiles preconfigured for specific server workloads

Thermal Radar 2.0
Multi-zone thermal monitoring with multiple ambient sensors, dynamic per-zone fan curves, reduced fan power consumption and improved system reliability.
