512GB DDR5 4800 ECC RDIMM kit for ThinkMate servers

This NEMIX RAM kit delivers 512GB of DDR5 4800 memory across sixteen 32GB registered DIMMs. Each module runs at 1.1V with CL40 latency and includes on-die ECC for data integrity. The 1Rx4 organisation and 288-pin RDIMM form factor target ThinkMate Supermicro SuperServer platforms listed by the supplier.

IT teams running ThinkMate 121H-TNR.

Administrators who need validated, high-capacity registered ECC memory for these specific ThinkMate models can install this kit with confidence. Buyers whose servers require a different DDR5 speed, unbuffered DIMMs, or a lower total capacity should look for modules matching their platform's qualified-vendor list.

DDR5 4800 registered ECC with 1Rx4 organisation

The combination of DDR5 4800 transfer rate, registered signalling, ECC and 1Rx4 rank layout determines whether a motherboard can initialise all sixteen modules at rated speed. Verify the server's memory QVL for this exact configuration before purchase.

Questions about this item

Will the 4800 MHz DDR5 RDIMMs run stably alongside existing 32 GB DDR5 4800 CL40 modules already installed in my ThinkMate server?

Yes, these 16 modules are DDR5 4800 CL40 1.1 V ECC RDIMMs with 1Rx4 organisation, so they match the speed, latency, voltage and rank of identical-spec sticks already in the system.

How can I verify the full 512 GB kit is recognised and running at 4800 MT/s with ECC active after installation?

Enter the server BIOS or UEFI and confirm all 16 DIMM slots show 32 GB each, the memory frequency reads 4800 MT/s (PC5-38400) and ECC status reports enabled or active.

Does the package contain only the sixteen 32 GB RDIMMs, or are any extra items such as heat spreaders or cables included?

The box holds exactly the 16 x 32 GB DDR5 4800 CL40 1.1 V ECC RDIMMs; no heat spreaders, cables or other accessories are supplied.
