256GB DDR5 ECC RDIMM kit for Thinkmate SuperServer

This 256GB kit contains four 64GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for Thinkmate SuperServer 611C-TN4R and 621C-TN12R systems that require registered error-correcting memory. The modules operate at 1.1V using major OEM DRAM from Samsung, Micron or Hynix. IT professionals handling mission-critical workloads will find the capacity and reliability suited to virtualisation and database tasks.

Verify DDR5 RDIMM slots

Confirm that your SuperServer motherboard has enough 288-pin DDR5 RDIMM slots to accept four modules. Check the system documentation for supported memory speeds, maximum capacity per channel and required population order for 2Rx4 registered DIMMs. Ensure the BIOS version recognises 64GB density modules at 4800 MT/s. Servers that only support unbuffered UDIMMs or lower-density registered DIMMs cannot use this kit.

Replaces smaller or slower DDR5 RDIMM configurations

This kit upgrades systems running lower-capacity DDR5 4800 RDIMMs or slower registered memory to the full 256GB limit across four slots. The jump is worthwhile when workloads exceed current memory headroom, causing swapping or VM density limits. It does not benefit builds that need UDIMM form factors, non-ECC memory or speeds beyond the 4800 MT/s rating.

Questions about this item

What comes inside the 256GB kit and is anything else required?

The kit contains four 64GB DDR5 4800 ECC RDIMM modules, giving 256GB total. No extra parts are needed for installation.

How do I decide between the 4800 speed and other DDR5 speeds for my Thinkmate server?

Choose DDR5 4800 (PC5-38400) when your Thinkmate SuperServer 611C-TN4R or 621C-TN12R specifies that speed; it matches the platform's native memory bus.

What does the CL40 latency mean once the memory is running in the server?

CL40 indicates 40 clock cycles of CAS latency at 4800 MT/s, which is the standard timing for DDR5-4800 registered ECC modules in these Thinkmate systems.
