Capacity and fit

This 32GB kit contains two 16GB DDR4 3200 registered DIMMs built for Thinkmate TWX-QS8 tower servers. IT teams order it to add ECC capacity to those specific platforms without mixing module densities. Buyers who need non-ECC memory or a different form factor cannot use this kit.

Registered ECC specification

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V and a 2Rx8 organisation. Registered buffering and on-die ECC protect data integrity under sustained server workloads. Systems that require unbuffered DIMMs or a different rank configuration will not accept these sticks.

Installation notes

Each 288-pin RDIMM seats in the standard DDR4 server slots; no heat spreader means clearance is rarely an issue. The most common mistake is populating slots in the wrong order for the TWX-QS8 memory topology, so follow the server manual’s population rules exactly.

Questions about this item

How does DDR4 3200 CL22 ECC registered memory perform inside a Thinkmate TWX-QS8 tower server?

The kit runs at 3200 MT/s with CL22 latency and 1.20 V, providing error-correcting registered operation that the server's memory controller expects for stable 24/7 workloads.

What does the PC4-25600 designation tell me about the module's data-rate ceiling?

PC4-25600 corresponds to a 3200 MT/s DDR4 transfer rate, which is the maximum bandwidth this registered DIMM delivers on the Thinkmate platform.

Will the 288-pin 2Rx8 RDIMMs fit the Thinkmate TWX-QS8-14E3 and TWX-QS8-24E3 memory slots without a heat spreader?

Yes, each 16 GB module uses the standard 288-pin DDR4 RDIMM form factor and low-profile design, so they install directly into the server's DIMM sockets.
