256GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 256GB of DDR5 memory across four 64GB registered DIMMs. It is built for THINKMATE Supermicro SuperServer platforms that require ECC RDIMM modules for stable operation. The memory runs at 4800MHz with CL40 latency at 1.1V.

Upgrading from lower-capacity RDIMMs

The kit replaces smaller DDR5 RDIMM sets when workloads demand more memory bandwidth and capacity for virtualization or database tasks. The jump is worth it when the server chassis has four available slots and the firmware supports 64GB dual-rank modules at this speed.

Installing four registered modules

Installation follows standard 288-pin DDR5 RDIMM procedure and typically takes minutes per module. Ensure the server BIOS is current and that the memory configuration matches the motherboard population rules for 2Rx4 registered DIMMs. Improper slot order is the most common cause of post failures.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on my THINKMATE Supermicro SuperServer 111C-NR?

Yes, each 64 GB module uses the standard 288-pin DDR5 RDIMM form factor required by the 111C-NR and the 121C-TN2R or 121C-TN10R platforms.

What is the correct way to populate the four 64 GB sticks, and which step do builders often miss?

Install all four modules in the slots specified by the server manual for a quad-channel configuration; the step often missed is fully seating each RDIMM until both ejector clips click locked.

How can I tell if one of the 2Rx4 ECC registered modules needs replacement later?

The server will log corrected ECC errors or report uncorrectable faults for a specific DIMM slot; swap the indicated 64 GB stick when the firmware flags it.
