512 GB DDR5 RDIMM kit for SuperMicro servers

This NEMIX RAM kit provides 512 GB of DDR5 4800 memory across eight 64 GB registered DIMMs. It is built for SuperMicro X13SEW-TF and X13SEW-F motherboards in enterprise server and workstation deployments. The modules operate at 1.1 V with CL40 latency and include on-die ECC for data integrity.

DDR5 4800 registered ECC limits capacity per channel

The DDR5 4800 interface delivers 38400 MT/s throughput while the registered buffer reduces electrical load on the memory controller. CL40 timing and 2Rx4 organisation set the access latency and maximum rank density per channel. ECC correction adds overhead that slightly reduces usable bandwidth compared to non-ECC equivalents.

Tool-free installation into 288-pin RDIMM slots

Each 288-pin module seats vertically in the motherboard DDR5 RDIMM sockets without cables or brackets. Alignment notches prevent backward insertion, and the registered design requires the platform to support registered memory. Common issues include mixing registered with unbuffered DIMMs or populating slots in an order the firmware does not recognise.

Questions about this item

Should I choose the 8 x 64 GB kit or a different capacity for the SuperMicro X13SEW-TF?

The kit provides 512 GB total across eight 64 GB modules, filling all channels on the X13SEW-TF for maximum bandwidth and capacity.

What does the 4800 MT/s rating deliver once the modules are installed in the X13SEW-F?

The DDR5 4800 modules run at PC5-38400 speed with CL40 latency, giving the platform its rated peak throughput for registered ECC workloads.

Does the 288-pin RDIMM interface limit the memory speed on this motherboard?

The 288-pin DDR5 RDIMM form factor matches the X13SEW-TF and X13SEW-F slots, so the 4800 MT/s rating is not capped by the connector.
