NEMIX RAM
Eight 96 GB DDR5 5600 registered ECC modules totalling 768 GB at 1.1 V CL46 for Supermicro B13DEE servers
This NEMIX RAM kit provides 768GB of DDR5 memory across eight 96GB registered DIMMs. It is built for Supermicro B13DEE servers and workstations that require ECC protection and registered buffering for stable operation under sustained load.
Eight 96GB modules deliver 768GB total, giving virtualisation hosts, in-memory databases and AI training nodes ample headroom for large datasets. The 2Rx4 organisation maximises density per channel, though the CL46 latency at 5600 MT/s may limit throughput for latency-sensitive tasks compared to lower-latency alternatives.
Modules run at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering and ECC add minimal power overhead per DIMM, so total draw scales with capacity rather than frequency. In a properly ventilated rack the kit operates silently with no active cooling required.

All eight modules in this kit are rated at 5600 MHz CL46 1.10 V. If slower DDR5 RDIMMs remain installed, the system will typically clock every module down to the lowest common speed, so the 4800 MHz sticks would set the pace for the whole array.
Enter the BIOS or UEFI on the SuperMicro B13DEE and confirm the memory map shows 768 GB total across all populated slots with ECC status reported as enabled or active.
The box contains the 768 GB kit — eight 96 GB 288-pin DDR5 RDIMM modules — and nothing else; no cables, brackets or thermal pads are included.
