Upgrade your Supermicro MicroCloud AS-3015MR-H8TNR RAM

What Types of RAM Are Supported in the Supermicro MicroCloud AS-3015MR-H8TNR?

• The Supermicro MicroCloud AS-3015MR-H8TNR supports UDIMM (Unbuffered DIMMs).

Which Memory Speeds Are Compatible With the Supermicro MicroCloud AS-3015MR-H8TNR?

• The server supports DDR5-4800, DDR5-5600.
• Keep in mind that if different speeds are mixed, all modules operate at the slowest DIMM speed.

What Is the Maximum Supported RAM Capacity for the Supermicro MicroCloud AS-3015MR-H8TNR?

• Up to 192GB (4 × 48GB) with UDIMMs.

How do I achieve the best performance for my Supermicro MicroCloud AS-3015MR-H8TNR?

• Populate DIMMs evenly across all channels and use the highest supported speed compatible with your CPU.

What is UDIMM?

• UDIMM (Unbuffered DIMM): Unbuffered DIMMs do not include a register or buffer, meaning they communicate directly with the memory controller. While they offer lower latency compared to RDIMMs and LRDIMMs, UDIMMs are typically used in desktops or workstations rather than servers, as they cannot support high memory capacities or intensive workloads.

General DIMM Population Guidelines for Supermicro MicroCloud AS-3015MR-H8TNR

• Do Not Mix UDIMMs
• If mixing memory speeds, all DIMMs will operate at the lowest speed.
• Install DIMMs starting furthest from the processor.
• Populate DIMMs evenly across all channels.
• Ensure all CPUs have memory installed for their DIMM slots to function.

Supermicro MicroCloud AS-3015MR-H8TNR Memory Installation Steps

• Power Off the server and disconnect it from power.
• Wear ESD Gear: Use an ESD wrist strap and work in an ESD-safe environment.
• Open the server and locate the DIMM slots.
• Inspect the slots for dust or debris and ensure proper alignment of the DIMMs.
• Follow the DIMM population order in the server manual.
• Firmly insert DIMMs until they click. Avoid using excessive force.
• Close the server and reconnect power.
• Verify the memory configuration in the BIOS.
