2 TB DDR5 RDIMM kit for Supermicro servers

This 2 TB kit assembles sixteen 128 GB DDR5 4800 modules into a single upgrade for Supermicro CloudDC SuperServer platforms. Registered ECC operation and a 4Rx4 organisation suit dense virtualisation and database workloads that demand maximum capacity per socket.

DDR5 4800 registered ECC interface limits

Registered buffering and ECC add latency overhead that caps raw throughput at the JEDEC DDR5 4800 transfer rate. The 4Rx4 rank structure increases electrical loading, so memory controllers must support quad-rank registered DIMMs at full speed without down-clocking.

2 TB capacity headroom for memory-bound workloads

Sixteen slots filled with 128 GB RDIMMs deliver 2 TB of addressable memory, eliminating swap pressure for large in-memory datasets and heavy container consolidation. Once all DIMM sockets are populated, further expansion requires a platform with additional memory channels or higher-density modules.

Questions about this item

Should I choose the 16 x 128 GB kit or a smaller capacity for my SuperMicro server?

The 2 TB kit provides 16 modules of 128 GB each, filling all slots on supported SuperMicro CloudDC SuperServer platforms for maximum registered ECC capacity.

What does the DDR5 4800 CL40 rating deliver in a registered server board?

The modules run at 4800 MT/s with CAS latency 40 at 1.1 V, giving standard JEDEC bandwidth for 4Rx4 registered DIMMs in compatible SuperMicro systems.

How does the 288-pin DDR5 RDIMM interface limit speed and capacity in practice?

The 288-pin registered DDR5 form factor supports the stated 4800 MT/s data rate and 4Rx4 organisation, capping each DIMM at 128 GB within the server memory controller limits.
