Exact-match DDR5 server kit

This NEMIX RAM kit delivers 768 GB of DDR5 ECC registered memory across eight 96 GB RDIMM modules. It runs at 4800 MT/s with CL40 latency at 1.1 V and is built to the precise rank, voltage and timing the Supermicro H13DSG-O-CPU motherboard expects for full-capacity operation.

Suited for full-population server builds

The registered architecture offloads the memory controller so every slot runs fully populated at rated speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption. Builders using UDIMM-only boards or workstations that require unbuffered modules should choose a different kit.

DDR5 4800 CL40 2Rx4 1.1 V spec

The single specification that decides fitment is the DDR5-4800 CL40 2Rx4 registered module at 1.1 V in 288-pin RDIMM form factor. If your platform demands a different speed, rank, voltage or form factor this kit will not be recognised or will run below its rated performance.

Questions about this item

How do I install the eight 96GB DDR5 RDIMMs in the Supermicro H13DSG-O-CPU and which population step is most often missed?

Populate all eight slots following the motherboard manual's exact DIMM sequence for eight modules; the step most often missed is skipping the prescribed order, which prevents the system from recognising the full 768GB at DDR5-4800.

What maintenance or replacement will this 2Rx4 registered ECC kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; only a failed DIMM would need replacement under the lifetime warranty.

What limit appears first when the 768GB kit runs sustained workloads at CL40?

The registered buffer and ECC logic keep every slot stable at the rated 4800 MT/s and 1.10 V, so the first limit encountered is the motherboard's maximum supported capacity of 768GB.
