System-Specific DDR4 ECC RDIMM Kit

This NEMIX RAM kit supplies 256GB of DDR4 3200 registered ECC memory in four 64GB modules. It is built for Thinkmate GPX-QN4-22E2-4NVLINK and GPX-QN12-24E2-10GPU GPU-optimised servers. The registered design and error-correction suit mission-critical workloads that demand data integrity.

4Rx4 Rank and CL22 Latency

Each 288-pin RDIMM uses a 4Rx4 organisation with CAS latency 22 at 1.20V. This rank structure and timing combination determines whether the server’s memory controller can populate all slots at the rated 3200MT/s speed. Verify the platform’s qualified vendor list before ordering.

Four-Module Kit With No Heat Spreaders

The package contains exactly four 64GB modules and no additional accessories, software or cooling hardware. Bare modules keep the profile low for dense server chassis, but airflow must be managed by the system’s own cooling design.

Questions about this item

What does the 3200 MT/s rating mean once the modules are installed in a Thinkmate server?

The kit runs at DDR4 3200 (PC4 25600) with CL22 latency, delivering the rated bandwidth when the platform selects the matching JEDEC profile.

How does the registered ECC interface affect usable capacity and error handling?

Registered ECC RDIMMs add a register between the DRAM and the memory controller, allowing the 4Rx4 organisation to scale to 256 GB while correcting single-bit errors on the fly.

What physical slot and clearance requirements do these 288-pin RDIMMs have?

Each module uses a standard 288-pin DDR4 RDIMM form factor with no heat spreader, so it fits any DDR4 RDIMM slot that accepts 1.2 V modules.
