768GB DDR5 ECC RDIMM kit

This kit delivers 768GB of DDR5 4800 registered ECC memory across eight 96GB modules. It is built for ThinkMate HDX-QN8-52E4 high-density servers that require maximum capacity with error correction. The 2Rx8 organisation and 1.1V operation suit dense multi-socket platforms running virtualisation, in-memory databases or large-scale analytics workloads.

Platform and slot validation

Confirm the server model is the ThinkMate HDX-QN8-52E4 and that all eight DIMM slots are free and keyed for 288-pin DDR5 RDIMMs. Verify the BIOS revision supports 96GB dual-rank modules at 4800 MT/s with CL40 timing. Registered ECC memory will not function in consumer desktop boards or in systems that accept only unbuffered DIMMs.

Ready-to-install matched set

The eight modules ship as a factory-matched kit, eliminating the need to mix individual sticks from different lots. No heat spreaders are included, so airflow in the server chassis must meet the vendor's thermal guidelines. No additional software, cables or firmware tools are bundled with the memory.

Questions about this item

Does the 8 x 96 GB kit ship as a matched set or do I need to buy additional modules separately?

The package contains eight 96 GB modules pre-matched as a single 768 GB kit; nothing else is required for installation.

Why choose the 2Rx8 96 GB modules instead of a lower-capacity alternative?

Each 2Rx8 module delivers 96 GB at 4800 MT/s CL40, so the eight-module kit reaches the full 768 GB capacity supported by the target server.

What does the CL40 latency mean when the memory runs at 4800 MT/s in a Thinkmate server?

CAS latency 40 at 4800 MT/s sets the timing the memory controller uses for each access; the registered ECC design adds one cycle for command buffering, which the server firmware accounts for automatically.
