System-specific server memory kit

This NEMIX RAM kit delivers 256 GB across two 128 GB DDR4 3200 registered ECC RDIMMs built for the THINKMATE GPX-QT8-24E2-8GPU GPU-optimised server. Each module runs at 1.2 V with CL22 latency and a 4Rx4 organisation using major OEM DRAM from Samsung Micron or Hynix. The 288-pin registered design targets mission-critical workloads that require error correction and signal integrity.

Registered ECC modules with OEM DRAM

Registered buffering reduces electrical load on the server memory controller while ECC corrects single-bit errors to protect data integrity during sustained GPU compute tasks. The 4Rx4 rank structure increases density per channel so the platform can reach 256 GB with only two slots populated. Modules are stress-tested under load before shipping to verify stability in the qualified Thinkmate chassis.

Tool-less DIMM installation in qualified slots

Installation follows the standard server procedure: power down, open the chassis, align the 288-pin key and press each RDIMM until the ejector tabs lock. Because the kit is validated for the specific Thinkmate model the firmware recognises the SPD timings automatically. The most common issue is mixing these registered modules with unbuffered DIMMs or populating slots in an order the motherboard manual does not support.

Questions about this item

Will the 4Rx4 DDR4 RDIMMs need any firmware updates or periodic re-seating during their service life?

No firmware updates or scheduled re-seating are required; the modules are validated at DDR4 3200 CL22 and run at 1.20 V for the life of the installation.

What thermal limit appears first when the 256 GB kit runs continuously at 3200 MT/s in a fully populated server?

The modules operate at the standard 1.2 V DDR4 voltage, so the platform’s DIMM-slot airflow limit is reached before any module-level thermal threshold.

How much power does each 128 GB stick draw and how much heat does it add to a 24/7 GPU server?

Each 128 GB RDIMM runs at 1.2 V within the DDR4 3200 specification, adding only the nominal registered-DIMM power budget to the chassis thermal load.
