Capacity and fit

This 768GB kit supplies twelve 64GB DDR4 3200 registered DIMMs built for Thinkmate RAX and QT series servers. The modules carry ECC and 4Rx4 organisation to meet the error-correction and density needs of enterprise workloads.

Thermals and power

Each module runs at 1.20V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during normal operation.

Sustained load behaviour

CL22 latency and 4Rx4 rank depth maintain signal integrity through extended compute sessions. Rigorous stress testing under load verifies stability for continuous duty in mission-critical environments.

Questions about this item

How do I install these 288-pin DDR4 RDIMM modules in my Thinkmate server and what step is often missed?

Power down the server, open the chassis, align each 288-pin RDIMM with the DDR4 slot key notch, press firmly until both retention clips click, then verify in BIOS that all 12 modules are detected at 3200 MT/s; the step often missed is seating every module fully so both clips engage.

What maintenance or replacement will this 768GB kit need over time?

The registered ECC DDR4 modules have no moving parts and require no scheduled maintenance; replacement is only needed if a module fails, which is covered by the manufacturer lifetime replacement warranty.

What limit appears first when this 4Rx4 memory runs sustained workloads?

The 4Rx4 rank density combined with CL22 latency at 1.20 V means the memory controller’s maximum supported rank-per-channel limit is typically reached before thermal or bandwidth constraints become an issue.
