System-specific DDR5 RDIMM for Supermicro

This 64 GB DDR5-6400 registered ECC module is built to the exact rank, voltage and timing the Supermicro X14SDV-36C-SP3F motherboard expects. It targets administrators who need a single, validated upgrade that runs at full rated speed without manual tuning.

Installing the 288-pin RDIMM into the correct slot

The board requires registered DIMMs, not unbuffered or SODIMM modules, so verify the population sequence in the system manual before seating the stick. A common error is mixing ranks or skipping the prescribed slot order, which prevents the server from recognising the full 64 GB capacity.

Confirm supported capacity

Check the motherboard manual for maximum memory per slot, approved DIMM configurations and any BIOS version requirements. This module is not suitable for platforms that only accept unbuffered memory or that limit registered DIMM populations to lower densities.

Questions about this item

How can I confirm the 64GB DDR5-6400 module is running at CL52 and 1.10V after installation?

Enter the server BIOS or use a tool like CPU-Z to verify the memory operates at 6400 MT/s with CL52 timings and 1.10V; the registered ECC design ensures the controller recognises the 4Rx4 rank at full 64GB capacity.

What exactly ships in the package and do I need any extra brackets or cables?

The box contains one 64GB 288-pin DDR5 RDIMM (part MR51200-944K1) with no heat spreader; no additional brackets, cables or adapters are required for the Supermicro X14SDV-36C-SP3F motherboard.

Should I choose the 4Rx4 64GB stick or a different rank for the X14SDV-36C-SP3F board?

The 4Rx4 64GB registered ECC module matches the board's qualified memory list, allowing full-capacity recognition and stable operation when populated according to the motherboard manual's slot order.
