Exact-match server upgrade

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 built to the precise rank, voltage and timing the Supermicro H13SSL-N memory controller expects for full-capacity recognition.

Registered ECC architecture

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. This combination stops silent data corruption and unplanned reboots before they reach production workloads.

Eight-slot headroom

Populating all eight channels delivers maximum bandwidth for memory-intensive databases and virtualization clusters. Systems limited to fewer slots or lower-density modules cannot reach this capacity, and boards requiring UDIMM or SODIMM form factors will not accept these RDIMMs.

Questions about this item

How do I replace a failed module in this 8 x 128GB DDR5 RDIMM kit?

Replace the single faulty 128GB DDR5 6400 CL52 1.10V 2Rx4 RDIMM with an identical module; the registered ECC design keeps the remaining seven modules running at full 1TB capacity while you swap it.

What thermal limit appears first when all eight DDR5 RDIMMs run continuously at 6400MT/s?

The bare 288-pin modules have no heat spreader, so case airflow must keep each 1.10V 2Rx4 DRAM package below its throttling point during sustained full-population load.

How much power does the full 1TB DDR5 kit draw at 6400MHz CL52 all day?

At 1.10V each of the eight 2Rx4 registered modules draws only its rated voltage, so total power stays low and the registered buffer reduces controller strain during 24/7 operation.
