Server Memory Kit for Supermicro H13SST-GC

This NEMIX RAM kit delivers 1TB of DDR5 capacity across eight 128GB registered DIMMs. It is built for the Supermicro H13SST-GC motherboard and provides ECC error correction with a registered buffer to support fully populated slots at rated speed.

Verify DIMM Population Rules Before Ordering

Consult the motherboard manual for supported capacities, approved population order, and installation steps. The kit uses 2Rx4 rank organisation at 1.10V with CL52 timing, so the memory controller must recognise this exact configuration for full operation.

Registered ECC Design for Continuous Operation

The 288-pin RDIMM form factor offloads the memory controller, allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. Modules ship without heat spreaders, relying on server chassis airflow for thermal management.

Questions about this item

Does the 1 TB kit ship as eight 128 GB RDIMMs or do I need to buy extra modules?

The kit contains eight 128 GB DDR5 6400 CL52 1.1 V 2Rx4 288-pin ECC registered RDIMMs, so no additional modules are required.

Should I pick a different speed or capacity for the Supermicro H13SST-GC?

This kit matches the board's DDR5 6400 PC5-51200 2Rx4 registered ECC specification exactly, so it is the correct choice for full 1 TB support.

Will the CL52 timing run at the rated 6400 MT/s once all eight slots are populated?

Yes, the registered architecture and exact 1.1 V CL52 spec let the memory controller recognise every slot and operate at the full 6400 MT/s data rate.
