NEMIX RAM
1TB DDR5 ECC RDIMM kit with eight 128GB modules at 4800MHz CL40 for ThinkMate Supermicro servers
This 1 TB kit contains eight 128 GB DDR5 4800 RDIMM modules built for the ThinkMate Supermicro SuperServer 111E-WR. ECC and registered operation protect data integrity in mission-critical workloads. The kit runs at 1.1 V with CL40 latency.
IT teams running the validated ThinkMate Supermicro 111E-WR platform gain a tested, high-density memory upgrade. Builders targeting other motherboards or desktop systems should look elsewhere because the modules are qualified only for this specific server.
The 4Rx4 rank organisation and 288-pin DDR5 RDIMM form factor determine whether the server memory controller can address the full 1 TB capacity. Verify the platform supports 4Rx4 registered DIMMs before ordering.

Yes, the 288-pin DDR5 RDIMM form factor matches the DDR5 RDIMM slots used by the ThinkMate Supermicro SuperServer 111E-WR.
Populate all eight slots following the motherboard's labelled channel order (e.g., CPU1_DIMM_A1, B1, C1, D1, then CPU2_DIMM_E1, F1, G1, H1) so each channel receives one 4Rx4 rank.
Replace the affected 128GB RDIMM once the system logs show a sustained increase in correctable errors, as the module itself is not field-serviceable.
