Server-grade DDR5 memory kit

This 512 GB kit delivers four 128 GB DDR5 4800 registered ECC RDIMMs built for the Thinkmate STX-NL-QE16 E4 nearline storage server. It targets administrators who need maximum registered capacity in a validated configuration. Buyers seeking unbuffered or non-ECC modules for consumer platforms cannot use this kit.

288-pin registered DIMMs with 4Rx4 organisation

Each module operates at 1.1 V and carries a CL40 latency rating without a heat spreader. The registered buffer and on-die ECC reduce electrical load on the server memory controller, allowing all four slots to be populated reliably. Systems that require unregistered DIMMs or a different pin count will not accept these modules.

Low-voltage DDR5 operation for dense server

Running at 1.1 V across all four modules keeps power draw modest while maintaining 4800 MT/s throughput in a fully populated chassis. The absence of heat spreaders assumes adequate chassis airflow directed over the DIMM slots. Environments with restricted airflow or passive cooling may require additional thermal planning.

Questions about this item

What DDR5 speed and CAS latency does this 512 GB kit run at?

The four 128 GB modules operate at DDR5 4800 with CL40 latency and 1.1 V.

What physical slot and pin count do these RDIMMs require?

Each module uses a 288-pin DDR5 RDIMM form factor for registered server DIMM slots.

How should the four 4Rx4 modules be populated for correct operation?

Install one module per channel following the motherboard manual population order; do not mix ranks within a channel.
