128GB DDR5 ECC RDIMM for ThinkMate 611/621

This 128GB registered DIMM is built for ThinkMate SuperServer 611C-TN4R and 621C-TN12R platforms. It delivers error-correcting, registered memory for enterprise workloads that demand data integrity and high capacity per slot.

Replaces lower-capacity or non-ECC DDR5 modules

The jump is worth it when a single 128GB stick consolidates multiple smaller DIMMs, freeing slots for future expansion while adding ECC protection for mission-critical server tasks.

128GB at DDR5-4800 CL40 1.10V 4Rx4

Handles large virtualisation clusters, in-memory databases and heavy compute jobs with registered buffering and 4Rx4 organisation. Capacity per slot is maxed out here; workloads needing more total memory must populate additional slots.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the memory slots on my Thinkmate 611C-TN4R or 621C-TN12R server?

Yes, this module uses the standard 288-pin DDR5 RDIMM form factor required by the Thinkmate 611C-TN4R and 621C-TN12R SuperServer platforms.

What is the correct way to seat this 4Rx4 ECC registered module, and what step do installers often miss?

Align the off-centre key notch with the slot, press straight down until both retaining clips click, then verify the BIOS recognises the full 128 GB at 4800 MT/s; the step often missed is enabling ECC in the firmware after installation.

When should I expect to replace this 1.10 V DDR5 ECC RDIMM in a server workload?

DDR5 registered ECC modules like this 4800 MT/s CL40 unit are rated for continuous operation and typically last the life of the server; replacement is only needed if a correctable error count exceeds the platform threshold or a module fails POST.
