256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains sixteen 16 GB DDR5 4800 registered ECC modules built for ThinkMate SuperServer 611C-TN4R and 621C-TN12R systems. It targets administrators who need maximum registered memory capacity in those specific platforms. Buyers requiring non-ECC or unbuffered memory cannot use this kit.

Thermals and power at 1.1 V

Each module operates at 1.1 V with no heat spreader fitted, relying on server chassis airflow for cooling. Registered buffering and ECC add minimal overhead while maintaining signal integrity under sustained loads. Power draw scales with the 16-module population and the 4800 MT/s data rate.

288-pin registered build implications

The 288-pin RDIMM form factor seats only in DDR5 RDIMM slots on qualified ThinkMate boards; it will not fit UDIMM or SO-DIMM sockets. Sixteen modules fill every slot in the supported configurations, leaving no room for further expansion. Installers must follow the platform's population rules to ensure all 16 modules are recognised.

Questions sur cet article

How do I install the 16 DDR5 RDIMM modules in the THINKMATE 611C-TN4R, and which step is often missed?

Populate all 16 slots in the order shown in the server manual, then verify in BIOS that 256GB at 4800MT/s and ECC are both active — the step most people skip is confirming ECC mode after boot.

What maintenance or replacement will the 1Rx8 ECC RDIMM kit need over its service life?

No routine maintenance is required; if a module fails, replace the single 16GB stick — the lifetime replacement warranty covers the part, and ECC logging will flag the faulty rank before it crashes the system.

What limit appears first when the 4800 CL40 1.1V registered memory runs sustained workloads?

The CL40 latency at 4800MT/s sets the throughput ceiling; sustained bandwidth tops out at the PC5-38400 rating, and the 1.1V registered design keeps thermals stable so latency, not heat, is the first bottleneck.
