NEMIX RAM 128GB DDR5 4800 2Rx4 CL40 1.1V ECC Registered RDIMM memory upgrade

128 GB DDR5 RDIMM for ASRock Rack GENOA2D24G-2L+

This 128 GB DDR5 registered DIMM is built for the ASRock Rack GENOA2D24G-2L+ motherboard. It delivers 128 GB of ECC protected memory in a single 288-pin module. The 2Rx4 organisation and 1.1 V operation match the board's memory controller requirements exactly. It is intended for servers that need maximum capacity per slot with full error correction.

Sustained load behaviour with registered ECC

The registered architecture buffers address and command signals so the memory controller drives every slot at full speed even when fully populated. ECC corrects single-bit errors on the fly preventing silent data corruption during long compute runs. CL40 timing at DDR5 4800 maintains consistent latency under continuous throughput. No heat spreader is fitted so airflow across the PCB must be provided by the chassis.

DDR5 4800 interface practical limits

The PC5-38400 interface caps peak bandwidth at the rated 4800 MT/s transfer rate. Registered DIMMs add one cycle of latency versus unbuffered modules which is fixed by the protocol. Maximum capacity per channel is defined by the motherboard not the module alone. Mixing ranks or voltages will prevent the system from training at the rated speed.
