High-Density Server Memory Kit

This NEMIX RAM kit delivers 768GB of DDR4 ECC registered memory across six 128GB modules. It is built for Thinkmate HDX series servers that require maximum registered DIMM capacity. The 4Rx4 organisation and CL22 latency at 3200 MT/s match the platform's qualified memory list. Modules operate at the standard 1.2V DDR4 voltage.

Suited For Qualified Thinkmate Platforms

This memory is validated for Thinkmate HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers. It is not suitable for consumer desktops, laptops or workstations that accept only unbuffered non-ECC UDIMMs. Systems limited to lower maximum capacity per slot or fewer than six DIMM slots cannot use the full kit. Buyers needing unregistered memory or lower voltages should look elsewhere.

Steady Throughput Under Continuous Load

Registered buffering and on-die ECC maintain data integrity during sustained write and read cycles typical of virtualisation hosts and database servers. The 1.2V operating voltage keeps power draw predictable when all six modules run at 3200 MT/s for extended periods. CL22 timing remains stable without the voltage increases required by tighter-latency kits. Heat spreaders are absent, so adequate chassis airflow is necessary for continuous operation.

Questions about this item

Does this 768GB kit require a THINKMATE server motherboard with 288-pin DDR4 RDIMM slots and registered ECC support?

Yes, the modules are 288-pin DDR4 RDIMM registered ECC memory designed for THINKMATE HDX-QT24-52E3, HDX-QN24-52E3 and HDX-QT24-32E3 high-density servers.

Can I mix these 4Rx4 128GB modules with existing 2Rx4 or 1Rx4 DDR4 3200 RDIMMs in the same server?

Mixing different rank organisations is not recommended; the server memory controller expects uniform 4Rx4 population across all populated channels for stable operation at 3200 MT/s.

How do I verify the kit is running at the rated 3200 MT/s CL22 after installation?

Check the BIOS memory information or OS tools such as dmidecode — each module should report 3200 MT/s, PC4-25600, CAS latency 22, 1.20 V and registered ECC status.
