Exact-match DDR5 kit for Supermicro H13SST-G

This 1 TB kit contains eight 128 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. The modules are registered, ECC-enabled and built with a 2Rx4 organisation using major OEM DRAM. They are intended for administrators upgrading the Supermicro H13SST-G motherboard to its full supported capacity.

Verify motherboard population rules before ordering

Consult the Supermicro H13SST-G manual for approved DIMM population order, maximum capacity per channel and any BIOS version requirements. The board requires 288-pin registered RDIMMs; unbuffered or SO-DIMM modules will not function. Confirm that your current configuration can accept eight dual-rank modules without exceeding the memory controller limits.

Registered ECC architecture for full-slot stability

The registered design reduces electrical load on the memory controller, allowing all slots to run fully populated at the rated 6400 MT/s speed. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. No heat spreaders are fitted, so ensure chassis airflow meets the server's thermal specifications.

Questions about this item

Does the kit include all eight 128 GB modules or must any be purchased separately?

The package contains the full 1 TB kit — eight 128 GB DDR5 6400 RDIMM modules — so nothing extra is needed for a complete installation.

Why choose the 1 TB 8×128 GB CL52 kit instead of a smaller capacity or different latency?

This exact-match kit delivers the full 1 TB your Supermicro H13SST-G supports with the 2Rx4 registered ECC layout and CL52 timing the board expects, ensuring every slot runs at rated speed.

Will the DDR5 6400 (PC5-51200) rating actually run at 6400 MT/s once installed in the H13SST-G?

Yes — the modules are spec-matched to the motherboard's memory controller, so the 6400 MT/s data rate and CL52 latency are recognised and sustained at the rated 1.1 V.
