256 GB DDR5 ECC RDIMM kit

This NEMIX RAM kit supplies 256 GB of DDR5 ECC registered memory in four 64 GB modules. It is built for servers and workstations that require error-correcting, registered DIMMs for data integrity under sustained loads.

Suited for SuperMicro B13DET platforms

The modules are validated for the SuperMicro B13DET motherboard and operate at DDR5 5600 with CL46 latency at 1.10 V. Systems that need unbuffered non-ECC DIMMs, lower capacities, or a different pin count should consider other memory types.

Fits 288-pin DDR5 RDIMM slots

Each stick uses the standard 288-pin DDR5 RDIMM form factor and runs at the JEDEC 1.10 V level. The registered design places light electrical load on the memory controller, leaving headroom for full population of all compatible slots on the target board.

Questions about this item

Does the SuperMicro B13DET motherboard need four empty DDR5 RDIMM slots to install this 256GB kit?

Yes, the kit contains four 64GB modules and each one occupies a single 288-pin DDR5 RDIMM slot on the board.

Will the CL46 timing of these 5600MHz modules slow down existing DDR5 4800MHz RDIMMs already installed in the same server?

The memory controller will run all populated slots at the lowest common speed, so 4800MHz modules will keep their native timing while the new modules operate at 4800MHz instead of 5600MHz.

How can I confirm the full 256GB is detected and ECC is active after installing the four modules?

Check the system BIOS or UEFI memory information screen; it should show 256GB total capacity and report ECC enabled for each 64GB RDIMM.
