NEMIX RAM
A 256 GB DDR5 ECC registered kit of sixteen 16 GB modules running at 4800 MT/s with CL40 latency and 1.1 V operation
This kit provides 256GB of DDR5 4800 memory across sixteen 16GB registered DIMMs. It is built for THINKMATE Supermicro SuperServer 121H-TNR, 221H-TNR and 221H-TN24R systems that require ECC RDIMM modules.
Verify that your server model matches the listed THINKMATE Supermicro SuperServer part numbers. Confirm the motherboard has enough free 288-pin DDR5 slots for all sixteen modules. Ensure the platform supports registered ECC RDIMMs at 1.1V with CL40 timing and 1Rx8 organisation.
Ideal for administrators expanding memory in the named SuperServer models for virtualisation or database workloads. Not suited for workstations or desktops that use unbuffered non-ECC DDR5. Buyers needing different capacities, speeds or form factors should look at other memory kits.
