1 TB DDR4-3200 ECC RDIMM kit for ThinkMate GPU

This 1 TB kit delivers sixteen 64 GB registered DIMMs validated for ThinkMate GPX-XS12-24S3-8GPU GPU-optimised servers. It targets IT teams that need maximum registered ECC capacity in a single qualified package.

Registered ECC and 4Rx4 organisation for dense

Registered buffering and on-die ECC protect data integrity under sustained multi-GPU workloads, while the 4Rx4 rank structure lets each module reach 64 GB without exceeding the platform’s electrical load limits. The 1.2 V operating voltage matches the server’s standard DDR4 rail.

DDR4-3200 bandwidth ceiling and fixed CL22 latency

The PC4-25600 interface caps peak throughput at the DDR4-3200 data rate, so applications that scale beyond this bandwidth must add more channels or move to a newer memory generation. CAS latency is fixed at CL22 and cannot be tightened on this registered module.

Questions about this item

Will the 16 modules of 4Rx4 DDR4 RDIMM need any maintenance or replacement later?

The modules have no heat spreader and run at 1.20V standard voltage. ECC registered design corrects single-bit errors on the fly. No moving parts or firmware updates are required. Lifetime replacement warranty covers any defect that appears in service.

What limit appears first when the 1TB kit runs at DDR4 3200 CL22 continuously?

The CAS latency of 22 cycles at 3200 MT/s sets the timing ceiling. Four-rank 4Rx4 organisation per module increases electrical load on the memory controller, so sustained bandwidth is bounded by the registered buffer and rank density before thermal limits.

How much heat and power do the 16 registered ECC modules produce all day?

Each 64GB module operates at 1.20V without a heat spreader. Registered buffering adds slight controller overhead. Total power scales with 16 modules at DDR4 3200; airflow across the bare PCBs keeps temperatures in normal server range.
