Compatible ThinkMate Tower Memory Kit

This 1 TB registered ECC kit contains eight 128 GB DDR4 3200 modules built for ThinkMate TWX-XS8 tower servers. Registered buffering and error correction protect data integrity in multi-socket workloads. The 288-pin RDIMM form factor matches the platform memory slots exactly. Modules operate at 1.2 V with CL22 latency for stable enterprise operation.

Suited for Qualified ThinkMate Servers

IT teams upgrading TWX-XS8-14S3, TWX-XS8-24S3 or TWX-XS8-24S 3.1 towers can install this kit without configuration changes. Buyers who need unbuffered UDIMM modules or non-ECC memory for consumer boards cannot use these registered DIMMs. Systems that require different rank organisation or voltage levels should look elsewhere. The kit is validated only for the listed ThinkMate platforms.

Registered ECC RDIMM With 4Rx4 Organisation

Each module uses a 4Rx4 rank layout that the memory controller must support for full capacity recognition. The registered interface adds one clock cycle of buffering to improve signal integrity across all eight slots. Error-correcting code detects and corrects single-bit errors during operation. This combination of registration, ECC and rank structure determines whether the server will POST with the kit installed.

Questions about this item

How often will the 128GB DDR4 RDIMM modules need replacement under normal server workloads?

The modules are built with ECC and registered buffering for continuous operation and carry a lifetime replacement warranty from the manufacturer.

What limit appears first when the 4Rx4 3200MHz kit runs at full capacity for extended periods?

The CL22 latency at DDR4 3200 sets the timing boundary before bandwidth or voltage constraints become a factor.

How much heat and power do the eight 1.2V registered DIMMs produce when the tower runs all day?

Each module operates at 1.20V without a heat spreader, so total power draw scales with the 1TB capacity while thermals rely on chassis airflow.
