512GB DDR4 3200 ECC RDIMM kit

This 512GB kit contains four 128GB DDR4 3200 registered DIMMs built for THINKMATE HDX servers. ECC and registered buffering protect data integrity in multi-socket workloads. IT teams specify it when virtualisation hosts or database nodes need maximum capacity per channel.

288-pin registered modules without heat spreaders

Each stick runs at 1.2V with CL22 latency and a 4Rx4 organisation. The bare PCB fits dense server boards where tall heat spreaders would block airflow or adjacent slots. Registered signalling reduces electrical load on the memory controller for stable operation at full population.

Replaces smaller RDIMM sets in qualified THINKMATE

The upgrade is worthwhile when the current configuration leaves DIMM slots empty or caps memory below the CPU limit. Buyers who need non-ECC UDIMMs or desktop-form-factor SO-DIMMs should look elsewhere.

Questions about this item

Does DDR4 3200 PC4-25600 run at 3200 MT/s in a THINKMATE HDX-XN24-52S3?

Yes, the kit is rated DDR4 3200 (PC4-25600) and will operate at that transfer rate when the server's memory controller supports it.

Will four 288-pin 128 GB RDIMMs fit the THINKMATE HDX-XN12-32S3 memory slots?

Each module is a standard 288-pin DDR4 RDIMM; the HDX-XN12-32S3 accepts registered DIMMs of this form factor.

What is the correct order to populate the 4Rx4 modules for quad-channel operation?

Install one module per channel following the motherboard's slot-colour guide; the common mistake is placing two modules in the same channel.
