ThinkMate Tower Server Upgrade Kit

This 128 GB kit comprises two 64 GB DDR4 3200 RDIMMs built for ThinkMate TWX-XS8 tower servers. The modules are validated for 3.1 platforms and carry ECC plus registered buffering for data integrity in mission-critical workloads. IT teams can install them in minutes to expand memory capacity on supported systems.

DDR4 3200 Registered ECC Constraints

The memory runs at 1.20 V with CL22 latency and a 4Rx4 organisation across 288 pins. Registered signalling adds a clock cycle, so the platform must support RDIMM topology and the PC4-25600 data rate. Systems limited to UDIMM slots or lower DDR4 speeds cannot use these modules.

Plain Green PCB With Major-Brand ICs

Samsung, Micron or Hynix chips are mounted on a standard-height board without a heat spreader, leaving the modules compatible with dense DIMM arrays. The bare PCB eases visual inspection and fits tight server chassis where taller heatsinks would block airflow. Each stick is stress-tested before shipping to confirm stability under sustained load.

Questions about this item

Should I buy the 128GB kit as two 64GB modules or look for a different capacity?

The kit ships as two 64GB RDIMMs giving 128GB total; this is the only capacity offered for this part number.

What does the DDR4 3200 speed mean when the modules are installed in a Thinkmate tower?

The modules run at 3200 MT/s with CL22 latency at 1.2V, delivering PC4-25600 bandwidth in the supported Thinkmate TWX-XS8 servers.

Will the 288-pin RDIMM interface work with my Thinkmate TWX-XS8-14S3 motherboard?

Yes, the 288-pin DDR4 RDIMM form factor with ECC and registered buffering is built for the Thinkmate TWX-XS8-14S3, TWX-XS8-24S3 and TWX-XS8-24S 3.1 tower servers.
