64GB DDR5 RDIMM kit for ThinkMate servers

This 64GB kit contains four 16GB DDR5 4800 modules built for ThinkMate Supermicro SuperServer 521C-NR systems. Each stick is a 288-pin registered DIMM with ECC and a CL40 latency at 1.10V. The modules use major OEM chips from Samsung, Micron or Hynix and ship without heat spreaders.

DDR5 4800 registered ECC bandwidth ceiling

The PC5-38400 interface tops out at 4800 MT/s per module, so total throughput scales with the number of populated channels the server board provides. Registered buffering adds one cycle of command delay but allows larger capacities per channel than unbuffered DIMMs. ECC correction handles single-bit errors transparently, which is mandatory for the target platform.

1Rx8 organisation decides slot population

Each 16GB module uses a single-rank 1Rx8 layout, so four sticks occupy four slots and present four ranks to the memory controller. Boards limited to fewer ranks per channel or fewer physical slots will not accept the full kit. Buyers needing higher density per slot or a different rank count must choose another part number.

Questions about this item

Should I pick the 4-module 64GB kit or a different capacity for this Thinkmate server?

The kit supplies 64GB as four 16GB RDIMMs; choose it when the server has four free DDR5 slots and the workload needs registered ECC memory at 4800MT/s.

What does the 4800MT/s rating deliver once installed in the SuperServer 521C-NR?

The modules run at DDR5 4800 with CL40 latency and 1.10V, giving the platform its rated PC5-38400 bandwidth for registered ECC workloads.

How does the 288-pin DDR5 RDIMM interface limit speed or capacity in this system?

The 288-pin registered DDR5 form factor locks the kit to DDR5 4800 operation; the server chipset and memory controller determine any higher speed or larger capacity support.
