NEMIX RAM 256GB DDR5 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H13DSG-OM motherboard. Each module runs at 1.1V with CL40 latency and a 1Rx8 organization. The registered design allows full population of every slot while ECC corrects single-bit errors to protect data integrity in production workloads.

Upgrade from partial or lower-capacity DDR5 RDIMM

Replacing a smaller kit or mixed-capacity DIMMs with this matched 16-module set ensures the memory controller sees identical rank, voltage and timing across all channels. The jump is worth it when your workloads need the full 256GB at the board's native DDR5 4800 speed without down-clocking or population errors.

Verify DIMM population rules

Consult the H13DSG-OM manual for the approved installation sequence and maximum supported capacity per channel. Confirm the board requires 288-pin Registered DDR5 RDIMMs and not UDIMM or SODIMM variants. Ensure your BIOS revision supports 16-module operation at the rated CL40 timing.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13DSG-OM motherboard slots?

Yes, this kit uses the 288-pin DDR5 RDIMM form factor required by the Supermicro H13DSG-OM motherboard, not UDIMM or SODIMM.

What is the correct installation sequence for all 16 modules on this board?

Consult the Supermicro H13DSG-OM manual for the approved DIMM population order; fully populated servers often require specific slot filling per channel to boot at rated speed.

When should the registered ECC modules be replaced in a production server?

Replace modules if ECC logs show rising correctable error counts, if the system reports uncorrectable errors, or during planned hardware refresh cycles to maintain data integrity.
