Supermicro 521C-NR-G1-OTO-40 rack server, Xeon Silver 4510, 128 GB DDR5, 2×960 GB SSD

SKU CH-W8RD-WB73W MPN 521C-NR-G1-OTO-40

Single-socket Xeon Silver 4510 server with 128 GB DDR5 and dual 960 GB SSDs

  • Intel Xeon Silver 4510 processor delivers 12-core performance for multi-threaded workloads
  • 128 GB DDR5 memory at 5600 MHz supports large datasets and virtualization
  • Two 960 GB SSDs provide fast boot and application storage
  • Single Socket E (LGA-4677) design accepts 4th/5th Gen Xeon Scalable CPUs up to 350 W TDP
  • Intel C741 chipset with OCP 3.0 AIOM slot and dedicated IPMI LAN enables flexible networking

Single-socket server platform

The Supermicro 521C-NR-G1-OTO-40 is a 1U rack server built around one Intel Xeon Silver 4510 processor. It ships with 128 GB of DDR5 memory installed across 16 DIMM slots and includes two 960 GB solid-state drives for storage. The Intel C741 chipset provides the platform foundation with a dedicated IPMI LAN port for remote management.

Suited for memory-heavy single-socket workloads

This configuration fits environments that need large memory capacity in a single-processor design, such as virtualisation hosts, database nodes or high-density compute clusters. Buyers requiring dual-processor scaling, GPU acceleration or more than 16 memory channels should evaluate alternative platforms that support those architectures.

16 DIMM slots at 5600 MHz DDR5

The board offers 16 DDR5 RDIMM slots running up to 5600 MHz with 3DS support, defining the maximum memory bandwidth and capacity ceiling for this chassis. Matching this slot count and speed to the application's memory footprint determines whether the system can deliver the required throughput.

Questions about this item

How do I verify the Xeon Silver 4510 is running at full 350W TDP after setup?

Check the IPMI dashboard or BIOS hardware monitor; it reports real-time CPU power draw and confirms the processor hits its rated thermal limit under load.

What ships with the 521C-NR-G1-OTO-40 and what must I add?

The system includes the Xeon Silver 4510, 128 GB DDR5 and two 960 GB SSDs; you still need an OCP 3.0 AIOM card for network connectivity and any extra drives or memory.

Should I populate all 16 DIMM slots or start with the factory 128 GB?

The server arrives with 128 GB DDR5 at 5600 MHz; add 3DS RDIMMs in matched sets only when your workload exceeds the installed capacity.
