Capacity and Compatibility

This 256GB kit contains eight 32GB DDR4 3200 ECC RDIMM modules built for ThinkMate RAX and QT server platforms. Registered buffering and 2Rx8 organisation allow the full capacity to be addressed on supported motherboards.

Thermals and Power

Each module runs at 1.20V with CL22 latency and no heat spreader, relying on chassis airflow for cooling. Registered operation adds minimal electrical load while maintaining signal integrity across all 288 pins.

Build and Connectors

Bare green PCBs with 288-pin DDR4 RDIMM edge connectors install directly into standard server DIMM slots. The kit omits heat spreaders, so adjacent slots remain accessible in dense configurations. Buyers needing unbuffered UDIMMs or lower-capacity kits cannot use this product.

Questions about this item

How do I install the 8 288-pin DDR4 RDIMM modules in the ThinkMate server and what step is often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify in BIOS that all 256GB are recognised at 3200MT/s; the step often missed is seating every module fully so both latches engage.

What maintenance or replacement will the 2Rx8 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; if a module fails the ECC logic will flag correctable errors and the lifetime replacement warranty covers a swap of the defective 32GB stick.

What limit appears first when the 1.20V CL22 registered memory runs under sustained load?

The CAS latency of CL22 at 3200MT/s sets the timing ceiling; thermal throttling is unlikely because the modules have no heat spreader and operate at the standard 1.20V.
