1 TB DDR5 ECC RDIMM kit

This 1 TB kit provides sixteen 64 GB DDR5 4800 modules built for ThinkMate RAX-XS4-21S4 rackmount servers. ECC and registered operation protect data integrity in mission-critical workloads. The modules run at 1.10 V with a CAS latency of CL40 and use a 288-pin RDIMM form factor. They are validated for compatibility with the specified ThinkMate platform.

Enterprise buyers needing maximum capacity

IT teams expanding memory in a ThinkMate RAX-XS4-21S4 server will match the exact qualified configuration. Builders targeting consumer desktops, laptops or non-ThinkMate workstations should look elsewhere because the registered ECC design and 2Rx4 organisation require a compatible server chipset. Systems limited to fewer than sixteen DIMM slots or lower maximum capacity per slot cannot use this kit.

Registered ECC with 2Rx4 organisation

The registered buffer and on-die ECC demand a motherboard that supports DDR5 RDIMM memory with 2Rx4 rank architecture. Without that support the modules will not initialise or will run in a reduced mode. Verify the server documentation for RDIMM qualification and maximum supported capacity before purchase.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the ThinkMate RAX-XS4-21S4 rackmount server?

Yes, the 288-pin DDR5 RDIMM modules are designed for the ThinkMate RAX-XS4-21S4 rackmount server.

What is the correct way to populate all 16 slots with these 2Rx4 registered modules?

Install the 16 modules in matched pairs following the server manual's population sequence for 2Rx4 registered DIMMs.

Will the Samsung, Micron or Hynix chipsets used in these modules require firmware updates later?

The major OEM chipsets are validated for the ThinkMate platform and do not require separate firmware updates.
