  • Full 48 GB capacity recognised at DDR5-6400 speed
  • Registered ECC design prevents silent data corruption
  • 10 V operation matches server memory controller spec
  • 2Rx8 288-pin RDIMM fits Supermicro H13SST-GC slot layout
  • CL52 latency runs at rated timing without downclocking

Exact-Match Server Upgrade

This 48GB DDR5 6400 CL52 ECC Registered RDIMM is built to the exact rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It delivers 48GB of registered, error-correcting memory at 1.10V for workloads that require full-capacity recognition and data integrity.

Installation And Population Rules

The module uses the 288-pin RDIMM form factor this board requires, not a UDIMM or SODIMM. Because server population rules vary by model, you must consult the system or motherboard manual for supported capacities and approved DIMM installation order before fitting the memory.

Sustained Load Stability

Registered architecture offloads the memory controller so every populated slot runs at the rated 6400 speed under continuous demand. On-the-fly ECC correction stops single-bit errors from becoming silent data corruption or unplanned reboots during long-running production tasks.

Questions about this item

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

Enter the server BIOS or use a hardware-information utility to verify the memory is detected as 48GB, operating at 6400 MT/s with CL52 timings and 1.10V, and that ECC is shown as active.

What is included in the package and are any extra components required for installation?

The kit contains one 48GB 288-pin DDR5 6400 CL52 2Rx8 1.1V ECC Registered RDIMM; no additional parts are needed beyond a compatible Supermicro H13SST-GC motherboard with an available RDIMM slot.

Which capacity or version should I choose for the Supermicro H13SST-GC?

This exact-match 48GB DDR5-6400 (PC5-51200) 2Rx8 Registered ECC RDIMM at 1.1V CL52 is the version specified for the H13SST-GC; select it when your configuration calls for a single 48GB module.
