1TB DDR4 3200 ECC RDIMM Kit

This 1TB memory kit contains eight 128GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. It is built for ThinkMate XS8-24S3 workstations that require ECC error correction and registered signal buffering for stable operation. The modules run at 1.2V and use a 288-pin RDIMM form factor with 4Rx4 organisation.

Who this suits and who should look elsewhere

IT teams upgrading a ThinkMate XS8-24S3 workstation to its full 1TB capacity will find the exact configuration validated for that platform. Builders needing non-ECC unbuffered DIMMs, lower capacities, different speeds, or memory for consumer motherboards must select a different kit.

Deciding specification: 4Rx4 registered ECC

The 4Rx4 registered ECC architecture determines whether the workstation’s memory controller can address the full 1TB across eight slots. If the system requires 2Rx4 or 2Rx8 ranks, or unbuffered non-ECC modules, this kit will not function.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the memory slots on a ThinkMate XS8-24S3 workstation?

Yes, the 288-pin DDR4 RDIMM form factor matches the registered DIMM slots used by the ThinkMate XS8-24S3 workstation.

Do I need to populate all eight slots at once, or can I add the 128GB modules in smaller groups?

The kit contains eight 128GB modules; install them in the channel order shown in the workstation manual to keep memory interleaving balanced.

Will the ECC and registered features continue to function without firmware updates?

ECC error correction and registered buffering are handled by the module hardware itself and do not rely on separate firmware updates.
