Exact-match DDR5-4800 RDIMM for Supermicro H13SST-G

This 64 GB DDR5 module runs at 4800 MT/s with CL40 timing at 1.1 V. It is a 2Rx4 registered ECC RDIMM built to the exact rank, voltage and timing the H13SST-G memory controller expects. The 288-pin form factor matches the board's DIMM slots so the server recognises the full capacity at rated speed.

Verified fitment and enterprise stability

The module is verified for the Supermicro H13SST-G motherboard, ensuring the registered architecture offloads the memory controller when every slot is populated. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads. No heat spreader is included, relying on server chassis airflow.

Installation depends on motherboard population rules

Server memory support varies by model, so the system or motherboard manual must be consulted for supported capacities, approved DIMM population order and installation steps before purchase. Using an incorrect slot sequence or mixing ranks can prevent the system from booting or recognising the full 64 GB.

Questions about this item

Will the 2Rx4 DDR5 RDIMM need any firmware updates or battery-backed maintenance over its service life?

No firmware updates or battery-backed maintenance are required for the registered ECC DDR5 RDIMM; the module operates at 1.1 V with CL40 timing and relies on the server's memory controller for error correction and health monitoring throughout its lifetime.

What thermal or power limit appears first when the 64 GB DDR5 4800 module runs continuously at full load?

The module draws power at its rated 1.1 V DDR5 voltage and has no integrated heat spreader, so the first limit under sustained load is the server chassis airflow and DIMM-slot cooling capacity rather than an on-module thermal throttle point.

How much noise and heat does the 288-pin RDIMM add when the system runs all day at 4800 MT/s?

The DDR5 RDIMM itself has no moving parts and produces no audible noise; its 1.1 V operation adds only modest heat that the server's existing fan curves and ducting are designed to dissipate during continuous 24/7 operation.
