256GB DDR5 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR5 4800 registered DIMMs built for Supermicro GPU SuperServer platforms including the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. Each module operates at 1.1V with CL40 latency and provides error-correcting code protection for data integrity. The 1Rx8 organisation suits dense memory configurations in enterprise workloads.

DDR5 4800 registered memory limits

Registered DDR5 4800 modules require a motherboard chipset and CPU memory controller that support the DDR5 RDIMM standard at the rated transfer rate. The registered buffer adds one clock cycle of latency compared with unbuffered modules and the platform must populate slots according to its validated population rules. Bandwidth and maximum capacity are defined by the server platform, not by the modules alone.

Installing sixteen 288-pin RDIMMs

Installation follows the server manual slot sequence; mixing ranks or skipping populated channels can prevent the system from posting. The modules have no heat spreader, so airflow across the DIMM sockets must meet the chassis specification. Firmware should be updated before adding the full 256GB to avoid training failures on cold boot.

Questions sur cet article

Should I choose the 16x16GB kit or a smaller capacity for my SuperMicro server?

The kit provides 256GB total across 16 modules of 16GB each; select it when your SuperMicro SYS-821GE-TNHR, SYS-821GV-TNR or SYS-421GE-TNRT requires the full 256GB population.

What does the 4800 MT/s rating deliver once the modules are installed?

The memory runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, giving the rated throughput and timing on the supported SuperMicro GPU SuperServer platforms.

How does the 288-pin registered DDR5 interface limit use in other systems?

These are 288-pin DDR5 RDIMM modules with ECC and registered buffering; they only operate in DDR5 RDIMM slots on the compatible SuperMicro servers listed.
