Exact-match DDR5-4800 kit for Supermicro

This 96 GB kit (2 × 48 GB) uses 288-pin DDR5 RDIMM modules rated at 4800 MT/s (PC5-38400) with CL40 latency and 1.1 V operation. Registered ECC architecture ensures the memory controller recognises the full capacity and runs at rated speed on the supported motherboard.

Sustained-load behaviour with registered ECC

Registered buffering offloads the memory controller so every slot remains stable when fully populated under continuous server workloads. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended operations.

Build and connector implications

Modules ship without heat spreaders, relying on the server chassis airflow for thermal management. The 288-pin RDIMM form factor matches the board's required slot type — not UDIMM or SODIMM — and the kit follows the motherboard's population rules for correct installation.
