Server Memory Kit 1.5TB Capacity

This NEMIX RAM kit provides 1.5TB of DDR4 server memory across six 256GB registered DIMMs. It is built for enterprise platforms that require ECC error correction and registered signal buffering at the DDR4 2933 standard. The modules operate at 1.2V with a CAS latency of 21. This product is not for desktop PCs or consumer motherboards lacking registered DIMM support.

Thermals Noise and Power Draw

Each module runs at the standard 1.2V DDR4 voltage, keeping power draw consistent with the DDR4 2933 specification. Registered buffering and ECC logic add minimal overhead during typical server workloads. Passive cooling via system airflow is sufficient for normal operation. No active cooling components are included or required by the kit design.

Sustained Load Behaviour

Under continuous heavy memory utilisation the 8Rx4 organisation maintains signal integrity through the registered interface. ECC corrects single-bit errors and detects multi-bit errors without halting the system. The DDR4 2933 speed rating is sustained across all six modules in supported server platforms. Stability depends on motherboard qualification and proper population rules.

Questions about this item

How do I install the six 256GB DDR4 RDIMMs and what step is often missed?

Power down the server, open the chassis, align each 288-pin module with the DDR4 slot key, press firmly until the ejector tabs click, then confirm all six are recognised in BIOS before closing the case.

What maintenance or replacement will the ECC RDIMM kit need over time?

The modules have no moving parts; dust the slots annually with compressed air, and replace any stick that begins reporting correctable ECC errors in the system event log.

What limit appears first when the 1.5TB kit runs sustained workloads at 2933MT/s?

The 1.2V DDR4 modules will hit thermal throttling or the platform's maximum registered DIMM capacity before the 21-cycle CAS latency becomes a bottleneck.
