384GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 384GB of DDR5 memory across six 64GB registered DIMMs. It operates at 4800MHz with CL40 latency and 1.1V voltage. The modules use 2Rx4 organisation and include ECC for error correction. They are built for SuperMicro SuperWorkstation SYS-531A-I and Super X13SRA-TF platforms.

Verify DDR5 RDIMM slot count and population rules

Confirm your motherboard has at least six 288-pin DDR5 RDIMM slots available. Check the system manual for supported memory population order and maximum capacity per channel. Ensure the platform accepts 2Rx4 registered modules at 4800MHz and 1.1V operation before installation.

Replaces smaller or slower DDR5 kits

This kit upgrades systems currently running lower-capacity DDR5 RDIMMs or mixed-speed modules. The jump is worthwhile when workloads require the full 384GB capacity and registered ECC stability. It is not for boards limited to unbuffered UDIMMs or fewer than six slots.

Questions about this item

What comes in the CSE-735D4-1K26B kit and do I need anything else to install it?

The kit contains six 64 GB DDR5 4800 ECC RDIMM modules for a total of 384 GB. No extra parts are required; the modules plug directly into the 288-pin slots of a compatible Supermicro system.

How do I decide between the available capacities or speeds for this Supermicro workstation?

This part number is a single 384 GB kit running at 4800 MT/s with CL40 latency. Other capacities or speeds would carry different part numbers, so choose this kit when the platform calls for 384 GB of DDR5 4800 registered ECC memory.

What does the 4800 MT/s rating mean once the modules are running in a SYS-531A-I?

The memory will operate at 4800 MT/s (PC5-38400) with a CAS latency of 40 at 1.10 V, delivering the rated bandwidth and error-correction capability for the Supermicro X13SRA-TF platform.
