NEMIX RAM
1.5 TB kit of sixteen 96 GB DDR5 4800 CL40 2Rx4 ECC registered DIMMs for Supermicro 241H and 241E servers
This 1.5TB kit contains sixteen 96GB DDR5 4800 CL40 registered ECC RDIMMs built for Thinkmate SuperServer 241H-TNRTTP and 241E-TNRTTP platforms. It targets administrators who need maximum registered memory capacity in those specific systems.
Each module runs at 1.10V without a heat spreader, relying on chassis airflow for cooling. Registered buffering and ECC add minimal latency overhead while maintaining signal integrity across all sixteen slots under sustained server workloads.
The 288-pin DDR5 RDIMM form factor fits the designated SuperServer memory slots directly. Populating all channels with 2Rx4 modules delivers the full 1.5TB capacity but leaves no free DIMM slots for future expansion without removing existing sticks.

Power down, open the chassis, align each 288-pin module with the keyed slot and press firmly until both latches click; the step often missed is populating all 16 slots in the exact channel order shown in the server manual so the 1.5 TB kit runs at 4800 MT/s.
The modules have no moving parts or heat spreaders, so routine maintenance is limited to keeping server airflow clean; if a 2Rx4 RDIMM ever fails, replace it with an identical DDR5 4800 CL40 1.10 V module to preserve ECC protection.
The primary limit is the DDR5 4800 bus bandwidth combined with CL40 latency; sustained heavy traffic will saturate throughput before the 1.10 V registered modules hit thermal or voltage constraints.
