NEMIX RAM
96 GB registered DDR5 kit with six 16 GB ECC modules at 4800 MT/s CL40 for Supermicro SuperWorkstation SYS-751A-I
This NEMIX RAM kit provides 96GB of DDR5 4800 registered ECC memory across six 16GB modules. It is built for the SuperMicro SuperWorkstation SYS-751A-I and Super X13DAI-T platforms that require registered DIMMs with error correction.
The upgrade makes sense when the workload demands data integrity through ECC and the motherboard requires registered modules at 4800MT/s. Systems already running registered DDR5 at the same speed and latency will not see a functional improvement.
The 288-pin modules seat in standard DDR5 RDIMM slots without tools. Populating all six channels per the board manual is essential; mixing ranks or skipping slots often prevents the system from posting.

Each 16 GB module uses a 288-pin DDR5 RDIMM socket; the kit contains six modules for a total of 96 GB.
Populate all six channels in the order shown in the motherboard manual so each 4800 MT/s registered DIMM initialises at 1.10 V with CL40 timing.
Run a full memory stress test after installation; ECC correction logs will reveal any chip degradation before it affects the 96 GB kit.
