Capacity and Compatibility

This 512GB kit contains four 128GB DDR4 3200 ECC registered DIMMs built for THINKMATE GPX-QS4-12E2-4GPU and GPX-QT8-22E2-8GPU GPU-optimised servers. It targets administrators who need maximum registered memory capacity in those specific platforms.

Thermals and Power

Modules run at 1.2V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering and ECC add minimal latency while keeping power draw low for dense 4Rx4 configurations.

Deciding Specification

The 4Rx4 rank organisation and CL22 timing at DDR4 3200 determine whether the memory controller can populate all slots at rated speed; verify the platform qualification list before purchase.

Questions about this item

How do I install the four 128 GB DDR4 3200 RDIMM modules in my Thinkmate server, and what step is often missed?

Power down the server, open the chassis, align each 288-pin module with its slot, press firmly until both retention clips click, then verify in BIOS that all 512 GB are detected at 3200 MT/s. The step often missed is populating the slots in the exact order the motherboard manual specifies for quad-rank 4Rx4 DIMMs.

What maintenance or replacement will this 512 GB DDR4 ECC RDIMM kit need over time?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required. If a DIMM fails, ECC will log corrected errors; replace the faulty 128 GB stick with an identical 4Rx4 CL22 1.20 V module to keep the quad-channel configuration balanced.

What limit appears first when this registered ECC memory runs sustained workloads?

The quad-rank 4Rx4 organisation increases electrical loading on the memory controller, so the practical limit is usually the maximum number of ranks per channel the Thinkmate platform supports; exceeding that forces the BIOS to down-clock below 3200 MT/s or disable slots.
