ThinkMate server memory kit

This 16 GB kit contains two 8 GB DDR4 3200 ECC registered DIMMs built for ThinkMate rackmount servers. The modules operate at 1.2 V with CL22 latency and use a 288-pin RDIMM form factor. IT teams can install the pair to expand capacity in qualified ThinkMate platforms.

Registered ECC with 1Rx8 organization

Each DIMM is a single-rank 1Rx8 module that presents registered ECC signalling to the memory controller. This organisation is the decisive factor for compatibility because ThinkMate server boards require registered ECC RDIMMs and will not accept unbuffered or non-ECC alternatives. Verify the server model against the approved list before ordering.

Low-voltage DDR4 operation

Running at 1.20 V, the modules draw minimal power and generate modest heat without a heat spreader. The registered buffer adds slight electrical load but keeps signal integrity stable under sustained workloads. Acoustic impact is negligible because the DIMMs have no moving parts and rely on chassis airflow.

Questions about this item

What does the 3200 MT/s speed mean when the kit is installed in a Thinkmate server?

The modules run at DDR4-3200 (PC4-25600) with CL22 latency, delivering the rated throughput once the platform enables the XMP or JEDEC profile.

How does the registered ECC interface affect usable bandwidth?

The RDIMM register adds one cycle of buffering, while ECC stores parity bits; both are handled by the memory controller without reducing the 3200 MT/s data rate.

Will the 288-pin RDIMMs fit the Thinkmate RAX-QN12 and related rackmount models?

Yes — the kit is validated for the RAX-QN12, QN24, QN4, QT10, QN10, QT24, QS12, QS4 and E2-E3 chassis that accept 288-pin DDR4 RDIMMs.
