Capacity and compatibility

This kit provides 1TB of DDR4 memory using sixteen 64GB registered DIMMs. It is built for ThinkMate XF4-24S3 workstations that require ECC RDIMM modules. The 4Rx4 organisation and 288-pin layout match the platform's memory controller. Systems needing unbuffered or non-ECC memory cannot use this kit.

Thermals and power

Each module operates at 1.20V without a heat spreader, relying on chassis airflow for cooling. Registered buffering adds minimal latency while reducing electrical load on the memory bus. Power draw scales with the sixteen-module population, so adequate power-phase capacity on the motherboard is necessary. No active cooling or specialised voltage regulation is included.

Included modules

The package contains the complete set of sixteen 64GB RDIMMs required to reach the 1TB total. No additional cables, software licences or configuration utilities are supplied. Installation follows the workstation manufacturer's standard memory population rules. The modules are validated for compatibility before shipment.

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules into my ThinkMate XF4-24S3, and what step is often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify all 16 modules are recognised in BIOS before closing the case.

What maintenance or replacement will the 16×64 GB ECC registered kit need over its service life?

No scheduled maintenance is required; if a module fails, replace the individual 64 GB RDIMM — each carries a lifetime replacement warranty from the manufacturer.

What limit appears first when the 3200 MT/s CL22 4Rx4 memory runs under sustained load?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; sustained throughput is bound by the DDR4-3200 data rate and quad-rank organisation.
