256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains sixteen 16 GB DDR5 4800 CL40 registered DIMMs operating at 1.1 V. It is built for ThinkMate Supermicro SuperServer platforms such as the 111C-NR and 121C-TN2R. ECC and registered buffering protect data integrity in mission-critical workloads.

Suited for ThinkMate server upgrades

Administrators expanding memory in the listed SuperServer models will find full compatibility and validated stability. Systems that require unbuffered UDIMMs, non-ECC modules, or a different DDR generation cannot use this kit.

Handles large virtualisation and database loads

The 256 GB capacity across sixteen ranks provides ample headroom for multi-tenant virtualisation, in-memory databases and heavy compute tasks. Workloads exceeding 256 GB or needing higher DDR5 speeds will outgrow this configuration.

Questions about this item

Do I need a motherboard that supports DDR5 4800 registered ECC RDIMMs to use this 256GB kit?

Yes, the modules are DDR5 4800 CL40 1.1V ECC registered RDIMMs, so the platform must support DDR5 registered ECC memory at that speed and voltage.

Can I add these 16 CL40 1Rx8 modules to a server that already has DDR5 RDIMMs installed?

They will operate at the lowest common speed and timing; all slots must support DDR5 registered ECC at 1.1V and the motherboard must accept the total 256GB capacity.

How can I confirm the kit is running at 4800 MT/s with CL40 after installation?

Check the BIOS memory information or a tool such as CPU-Z to verify DDR5 4800 frequency, CL40 latency, 1.1V voltage and ECC registered status for all 16 modules.
