512GB DDR4 ECC RDIMM kit for Thinkmate

This 512GB kit contains eight 64GB DDR4 3200 PC4-25600 registered DIMMs built with ECC and a 4Rx4 organisation. It is designed for Thinkmate HDX-QT24 and HDX-QN24 server platforms that require registered memory with error correction. Buyers needing non-ECC unbuffered modules or consumer desktop speeds should look elsewhere.

Sustained load stability at 1.2V and CL22

Each module operates at 1.20V with a CAS latency of 22, delivering consistent throughput under continuous enterprise workloads. The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity when all twenty-four or thirty-two slots are populated. Systems that demand higher frequencies or lower latencies than DDR4 3200 CL22 will not be satisfied by this kit.

288-pin RDIMM form factor without heat spreaders

The 288-pin DDR4 RDIMM sticks fit standard server DIMM slots and rely on chassis airflow for cooling since no heat spreaders are fitted. Major OEM chips from Samsung, Micron or Hynix are used across the eight modules in the kit. Builders who require tall heat spreaders, RGB lighting or proprietary form factors will find this package unsuitable.

Questions about this item

Does the 1.20V DDR4 3200 kit run cooler than higher-voltage server memory during 24/7 workloads?

Yes, the 1.20V operating voltage keeps power draw and heat lower than older 1.35V or 1.5V registered DIMMs, helping the eight 64GB modules stay within thermal limits in dense THINKMATE HDX chassis.

What motherboard feature must my THINKMATE server already have to accept these 4Rx4 registered ECC DIMMs?

The board must provide 288-pin DDR4 RDIMM slots that support quad-rank x4 registered ECC modules and the PC4-25600 speed grade.

Will these 4Rx4 CL22 modules work alongside older dual-rank DDR4 RDIMMs already installed in my HDX-QT24?

Mixing 4Rx4 and 2Rx4 ranks is not recommended; the memory controller treats each rank differently and can default to slower timings or fail to train, so populate all eight slots with this matched kit instead.
