NEMIX RAM
A 128 GB DDR4 3200 ECC registered DIMM built for Thinkmate rackmount servers
This 128GB DDR4 3200 ECC RDIMM module is built for Thinkmate rackmount servers including the RAX-PT10-11A1, RAX-PT8-12A1 and RAX-PT12-12A1. It provides registered error-correcting memory for workloads that require data integrity. The single-module design fits one 288-pin slot. It is not suited for desktop boards that cannot address 4Rx4 registered DIMMs.
The module operates at the standard DDR4 voltage of 1.20V without a heat spreader. Registered buffering and ECC logic add minimal overhead, so power draw stays within normal DDR4 limits for high-density server DIMMs. Acoustic output depends entirely on the server chassis fans; the memory itself produces no noise. It is not designed for overclocked or elevated-voltage configurations.
The 4Rx4 rank structure means the memory controller must support quad-rank x4 devices at 128GB per module. Systems limited to dual-rank or x8 organisations will not recognise the full capacity. Verify the Thinkmate service manual lists 4Rx4 support before purchasing. Buyers who need a module their platform can address should check their qualified-vendor list for the correct rank configuration.

Power down the server, open the chassis, align the module notch with the slot key, press firmly until the ejector clips lock automatically, then verify the full 128GB appears in the BIOS memory map before closing the case.
The module has no moving parts or heat spreader and requires no scheduled maintenance; if a correctable error count rises or a DIMM fails POST, replace the single 128GB stick with an identical PC4-25600 CL22 4Rx4 part.
The CAS latency of CL22 at DDR4 3200 sets the timing floor; under continuous load the memory controller will hit its maximum sustainable throughput before the 1.20V modules reach any thermal or voltage ceiling.
