128 GB DDR5 RDIMM for Thinkmate STX-NL-QE16 E4

This 128 GB DDR5 4800 registered DIMM is built for the Thinkmate STX-NL-QE16 E4 nearline storage server. It delivers ECC protection and registered buffering for data integrity in mission-critical workloads. The single-module design fills one slot with maximum capacity.

Replaces lower-capacity or non-ECC DDR5 modules

The jump is worth it when your server needs 128 GB per slot with error correction and registered signalling. Systems running virtualisation, large databases or high-throughput storage benefit from the density and stability. Modules without ECC or registered buffers cannot meet those requirements.

Verify DDR5 RDIMM support and slot population rules

Confirm the motherboard accepts 288-pin DDR5 RDIMMs at 1.1 V with CL40 timing and 4Rx4 organisation. Check the server manual for maximum memory per channel and any rank-per-channel limits. Ensure the firmware revision supports 128 GB single-rank modules before installation.

Questions about this item

Will the 288-pin DDR5 RDIMM fit my ThinkMate STX-NL-QE16 E4 server motherboard?

Yes, the 288-pin DDR5 RDIMM form factor matches the memory slots on the ThinkMate STX-NL-QE16 E4 nearline storage server for which this module is validated.

What is the correct way to seat this registered ECC module so the server recognises the full 128 GB capacity?

Align the key notch on the module with the slot ridge, press down firmly until both retention clips click into the side notches, then verify in BIOS that the 4Rx4 rank and CL40 timings are detected.

Does the module require any firmware updates or heat-spreader maintenance over its service life?

No firmware updates are needed for the memory itself; the module has no heat spreader, so only standard server chassis airflow and periodic dust cleaning are required.
