1TB DDR5-4800 ECC RDIMM kit

This kit provides 1TB of DDR5 server memory across eight 128GB registered DIMMs. It operates at 4800MT/s with a CL40 latency and 1.10V voltage. The modules use a 4Rx4 organisation and 288-pin form factor for compatible SuperMicro systems.

Suited for SuperMicro GPU SuperServer upgrades

Administrators expanding SYS-821GE-TNHR, SYS-821GV-TNR or SYS-421GE-TNRT platforms can populate all channels with matched ECC registered modules. Builders needing unbuffered UDIMMs, non-ECC memory or lower-capacity DIMMs for different motherboards should look elsewhere.

Eight-module 4Rx4 registered configuration

The kit delivers its full 1TB capacity only when all eight 128GB 4Rx4 RDIMMs are installed together in a motherboard that supports this rank structure and registered signalling. Mixing with other ranks or module types will prevent the system from recognising the full capacity.

Questions about this item

Does the kit include all eight 128 GB modules or must any be bought separately?

The package contains the full 1 TB kit with eight 128 GB DDR5 RDIMMs, so no additional modules are required for the listed capacity.

Which DDR5 speed and latency combination does this 1 TB kit provide?

The modules run at DDR5 4800 with PC5-38400 rating and CAS latency CL40 at 1.1 V.

What does the 4800 MT/s rating mean once the memory is installed in a compatible Supermicro server?

The server will operate the kit at 4800 MT/s with ECC registered operation, delivering the rated bandwidth and error-correction for supported workloads.
