ThinkMate-compatible DDR4 kit

This 128GB kit delivers two 64GB registered ECC RDIMMs validated for ThinkMate server and workstation platforms. It targets IT teams and system builders who need reliable, high-density memory for virtualization, database or compute workloads on supported hardware.

Fits registered DDR4 slots on qualified boards

The modules install into standard 288-pin DDR4 RDIMM sockets and operate at 1.2V, leaving headroom for other components on the power budget. ECC and register buffering free the memory controller from single-bit errors and electrical loading, improving stability in multi-DIMM configurations.

Runs at DDR4 3200 with CL22 latency

Rated speed is 3200 MT/s (PC4-25600) at CAS latency 22. The 4Rx4 organization spreads density across four ranks per module without a heat spreader, so airflow across the DIMM area is the primary thermal path in normal server chassis environments.

Questions about this item

Will the CL22 latency become a bottleneck during sustained heavy workloads on this ThinkMate kit?

CL22 is the rated CAS latency for these DDR4-3200 modules; sustained throughput depends on the server memory controller and workload profile rather than latency alone.

How much heat and power should I expect from two 64 GB registered DIMMs running continuously?

Each module operates at 1.20 V without a heat spreader; registered ECC RDIMMs typically draw a few watts per stick, so total heat is modest but chassis airflow still matters.

What motherboard feature must my ThinkMate system already have to use this 4Rx4 registered ECC memory?

The board must support DDR4 registered ECC RDIMMs with 4Rx4 organisation and 288-pin slots; standard unbuffered consumer slots will not work.
