256GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit supplies 256GB across two 128GB DDR5 4800 registered DIMMs. It targets administrators expanding Thinkmate Supermicro SuperServer 611C-TN4R or 621C-TN12R platforms that require ECC registered memory.

Servers needing registered ECC at 4800 MT/s

The modules suit environments that mandate 4Rx4 organisation, 1.1V operation and CL40 timing on the qualified Thinkmate SuperServer models. Builders using consumer motherboards, unbuffered DIMM slots or slower DDR5 speeds should look elsewhere.

4Rx4 registered DDR5 organisation

Each 128GB module implements a 4Rx4 layout that the compatible SuperServer 611C-TN4R and 621C-TN12R memory controllers expect; mismatched rank configuration will prevent the system from posting.

Questions about this item

How do I verify the 4800 MT/s speed and CL40 latency are active after installing the modules?

Enter the server BIOS or UEFI and confirm the memory frequency reads 4800 MT/s with timings showing CL40; the registered ECC design also lets the OS report corrected error counts if any occur.

What ships in the kit and are any extra parts required for installation?

The kit contains two 128 GB 288-pin DDR5 RDIMMs for a total of 256 GB; no additional cables, brackets or cooling accessories are needed — just seat the modules in the compatible ThinkMate Supermicro server slots.

Which capacity version should I choose for a ThinkMate SuperServer 611C-TN4R or 621C-TN12R?

This 256 GB kit (2 × 128 GB) is the listed configuration validated for those SuperServer models; select it when you need the full 256 GB registered ECC capacity at 1.1 V.
