768GB DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 768GB of DDR4 3200 ECC registered memory across twelve 64GB modules. It is built for ThinkMate rackmount servers that require high-capacity, error-correcting DIMMs for stable operation under sustained workloads.

Upgrade from lower-capacity DDR4 RDIMMs

Replacing smaller registered DIMMs with this 12x64GB kit expands total system memory to 768GB, allowing larger datasets to remain in RAM. The jump is worth it when virtualisation, in-memory databases or heavy multi-tenant workloads exceed the capacity of existing modules.

Suited for ThinkMate RAX, XS, XT.

IT teams running compatible ThinkMate platforms gain a validated, high-density memory solution with ECC protection. Builders needing unbuffered UDIMMs, non-ECC modules or speeds beyond DDR4 3200 should look at other product lines.

Questions about this item

Does the 288-pin DDR4 RDIMM form factor fit the memory slots in my Thinkmate RAX-XN24 server?

Yes, each 64 GB module is a standard 288-pin DDR4 RDIMM, the exact form factor used by the listed Thinkmate rackmount servers.

Do I need to populate all 12 slots at once, or can I start with fewer modules?

You can install fewer than 12 modules, but follow the server manual’s population order; the common mistake is skipping the required slot sequence for registered ECC DIMMs.

Will the Samsung, Micron or Hynix chips on these modules need any firmware updates or periodic replacement?

No, the DRAM chips are fixed hardware; once seated they require no firmware updates and no scheduled replacement under normal server operation.
