  • 2 V operation reduces power draw per module
  • Validated for ThinkMate GPU-optimized server configurations

Target system & module type

This 64 GB DDR4 ECC RDIMM is built for ThinkMate GPU-optimised servers that require registered, quad-rank memory. It plugs into a 288-pin slot and runs at 1.20 V with a CL22 latency profile.

Replacing standard unbuffered DIMMs

When a workload exceeds the capacity or error-correction limits of consumer modules, this registered 4Rx4 stick adds 64 GB of protected memory in a single slot. The upgrade is worth it once ECC and registered signalling become mandatory for data integrity.

Sustained load behaviour

Modules are stress-tested under continuous load to verify stability in multi-GPU server configurations. The registered buffer and ECC logic maintain consistent throughput during extended compute sessions without generating correctable errors.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 RDIMM form factor matches standard server DIMM slots used in compatible Thinkmate systems.

What is the correct seating procedure for the 4Rx4 registered module?

Align the notch with the slot key, press firmly until both side clips click, and verify the 1.2V CL22 module registers in BIOS.

When should the Samsung, Micron or Hynix chipset module be replaced?

Replace only if memory diagnostics report uncorrectable ECC errors or the system fails to recognise the 64GB capacity at 3200MHz.
