2TB DDR5 ECC RDIMM kit for ThinkMate servers

This 2 TB memory kit contains sixteen 128 GB DDR5 4800 RDIMM modules built for ThinkMate Supermicro SuperServer 521GE-TNRT and 421GU-TNXR platforms. It targets administrators who need maximum registered ECC capacity in those qualified systems.

DDR5 4800 registered ECC operates at 1.1 V

The DDR5 4800 standard (PC5-38400) sets the data rate and voltage floor for this kit; registered buffering and 4Rx4 organisation add latency overhead that limits raw speed compared with unbuffered alternatives. ECC correction and register delays are inherent to the registered DIMM architecture.

Replaces smaller RDIMM sets

The jump is worth it when the workload demands a single 2 TB population at the native 4800 MT/s rate without down-clocking. It is not for systems that cannot address 16 x 128 GB registered modules or that require unbuffered or non-ECC memory.

Questions about this item

Should I buy the 2TB kit as sixteen 128GB modules or choose a different capacity?

This kit supplies exactly 2TB across sixteen 128GB RDIMMs. Choose it when your workload needs the full 2TB; otherwise select a smaller kit that matches the capacity your server board can populate.

What does the 4800 MT/s rating deliver once the modules are installed in a ThinkMate SuperServer?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V, providing the rated throughput and error correction for the qualified ThinkMate platforms.

Does the 288-pin DDR5 RDIMM interface limit the speed or rank configuration I can use?

The 288-pin DDR5 RDIMM form factor carries 4Rx4 organisation at the rated 4800 MT/s; the registered interface and ECC are handled by the server chipset within that specification.
