ThinkMate Server Memory Kit

This 32 GB kit contains two 16 GB DDR4 3200 RDIMM modules built for ThinkMate RAX rackmount servers. Registered ECC operation and 2Rx8 organisation provide the error correction and signal integrity required by multi-socket server platforms.

Thermals and Power Profile

Modules run at the standard DDR4 1.20 V without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable under sustained workloads.

Build and Connector Details

Each module uses a 288-pin RDIMM edge connector keyed for DDR4 server slots. The absence of a heat spreader keeps the profile low for dense DIMM populations, while the registered design ensures compatibility with the ThinkMate RAX-XS4 and RAX-XH2 platforms listed.

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules in my ThinkMate server?

Power off the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then close the case and power on to verify 32 GB is detected.

What maintenance or replacement will this ECC registered memory need over time?

No scheduled maintenance is required; the modules carry a lifetime replacement warranty, so a failed stick is simply swapped for a new one without opening the server again.

At what point does the CL22 latency become the bottleneck during sustained workloads?

Under continuous heavy load the CAS latency of 22 cycles at 3200 MT/s limits throughput before thermal or voltage constraints appear on these 1.2 V registered DIMMs.
