256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains eight 32 GB DDR5 4800 CL40 registered DIMMs built for Thinkmate Supermicro SuperServer 511E-WR and 521E-WR platforms. It targets administrators who need maximum registered ECC capacity in those specific systems.

Registered ECC with 1Rx4 organisation

Each module is a 288-pin DDR5 RDIMM running at 1.1 V with a single-rank 1Rx4 layout and CL40 latency. The registered buffer and on-die ECC are the decisive specifications for compatibility with the target server motherboards.

Fills eight slots on validated Thinkmate boards

The kit occupies all eight DIMM slots on the qualified SuperServer models, delivering 256 GB of registered ECC memory without mixing capacities. It is not for systems that require unbuffered UDIMMs, non-ECC modules or a different DDR generation.

Questions about this item

What does the 4800 MT/s rating mean for real-world throughput in a ThinkMate server?

The modules run at 4800 MT/s with CL40 latency, giving each 32 GB stick a PC5-38400 peak bandwidth rating when the platform drives them at that speed.

How does the DDR5 RDIMM interface and ECC registration affect usable capacity and error handling?

Registered DDR5 ECC RDIMMs add a register between the DRAM and the memory controller, allowing the 8×32 GB kit to present 256 GB while correcting single-bit errors on the fly.

What physical slot and keying does the 288-pin DDR5 RDIMM need to fit?

Each module uses the standard 288-pin DDR5 RDIMM form factor with the DDR5 key notch, so it seats directly into a compatible server DIMM socket.
