512GB DDR5 ECC RDIMM kit

This 512GB kit contains sixteen 32GB DDR5 4800 registered DIMMs built for Thinkmate SuperServer 611C-TN4R and 621C-TN12R platforms. It targets administrators who need maximum registered ECC capacity in those specific systems.

16-module registered DDR5 population

The modules are 1Rx4 registered ECC RDIMMs that occupy all sixteen DDR5 slots in the compatible Thinkmate SuperServer chassis. Filling every slot leaves no free DIMM sockets for further expansion without removing existing modules.

CL40 1.1V headroom at 4800 MT/s

At the rated 4800 MT/s speed and CL40 latency the kit delivers 512GB of error-correcting capacity for virtualisation, database and compute workloads. The fixed sixteen-module configuration means total capacity cannot be increased beyond 512GB on these platforms.

Questions about this item

What limits the 16-module kit at CL40 when the ThinkMate 611C-TN4R runs sustained workloads?

The 4800 MT/s DDR5 RDIMMs operate at 1.1 V with a CL40 latency ceiling; ECC error correction adds verification cycles that become the first bottleneck during continuous throughput.

How much heat and noise do the 16 registered DIMMs generate inside a ThinkMate 621C-TN12R running all day?

Modules lack a heat spreader and draw 1.1 V each; registered buffers and ECC logic produce modest warmth, so chassis airflow — not the RAM — dictates temperature and fan noise.

Which ThinkMate server must I already own for this 512 GB kit to function?

The kit is validated for ThinkMate Supermicro SuperServer 611C-TN4R and 621C-TN12R; the motherboard must provide 16 DDR5 288-pin RDIMM slots and support 1Rx4 registered ECC modules.
