Supermicro H14DSG-O-CPU DDR5 Upgrade

This 48GB DDR5 6400 RDIMM is built as an exact-match upgrade for the Supermicro H14DSG-O-CPU motherboard. It targets server administrators who need registered ECC memory that the platform recognises at full capacity and rated speed.

288-Pin RDIMM Installation Notes

The module uses the 288-pin registered form factor this board requires, not UDIMM or SODIMM. Follow the motherboard manual for approved population order and per-slot capacity limits; incorrect slot filling or mixing ranks will prevent the system from posting at the rated 6400 speed.

Sustained Load Stability

Registered architecture offloads the memory controller so every populated slot runs at the full 48GB capacity continuously. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production workloads.

Questions about this item

How do I confirm the 48GB DDR5 6400 CL52 module is running at its rated speed after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s with CL52 timings at 1.1V. The Supermicro H14DSG-O-CPU should auto-detect the 2Rx8 registered ECC RDIMM and display full 48GB capacity per DIMM without manual configuration.

What is included in the package and what must be purchased separately?

The box contains one 48GB DDR5 6400 PC5-51200 2Rx8 1.1V CL52 288-pin ECC registered RDIMM. No heat spreader, cables, or additional hardware are included. Nothing else is required if your motherboard has an available 288-pin RDIMM slot and supports the specified capacity.

Which version should I choose for the Supermicro H14DSG-O-CPU motherboard?

Select the exact 48GB DDR5 6400 CL52 2Rx8 1.1V ECC registered RDIMM with part number MR51200-4828K1. This matches the motherboard's required registered DIMM form factor, rank structure, voltage, and timing for full compatibility and rated performance.
