NEMIX RAM
64 GB DDR5 4800 ECC RDIMM kit (2 × 32 GB) validated for SuperMicro X13SEW-TF and X13SEW-F motherboards
This kit provides 64 GB of DDR5 memory in a matched pair of 32 GB modules. It is built for SuperMicro X13SEW-TF and X13SEW-F motherboards that require registered ECC RDIMMs.
System administrators upgrading compatible SuperMicro servers or workstations will gain error-correcting registered memory at 4800 MT/s. Builders using consumer boards, non-ECC platforms or laptops cannot use these RDIMMs.
Confirm your motherboard accepts 288-pin DDR5 RDIMMs with 1Rx4 organisation and 1.10 V operation. Check the vendor memory-qualified list for the exact part number MR38400-314K2 and ensure the BIOS revision supports this speed and capacity.

The modules run at the standard 4800 MT/s JEDEC speed and 1.10 V, so a current BIOS that supports DDR5 4800 will detect them without extra steps.
Registered and unbuffered DIMMs cannot be mixed on the same platform; all populated slots must use registered ECC RDIMMs for the system to operate.
Check the memory timing readout in the BIOS or a tool such as CPU-Z; it should report 4800 MT/s with CAS latency 40 (CL40) for each 32 GB module.
