768GB DDR4 ECC RDIMM kit

This 768GB kit contains six 128GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for ThinkMate TWX-QS8-14E3 and TWX-QS8-24E3 tower servers that require 288-pin 4Rx4 modules at 1.2V.

Sustained workload stability

Modules are stress tested under load to maintain data integrity during continuous operation in multi-socket server environments. Registered buffering and ECC correction reduce errors when all six slots are populated at full 3200 MT/s speed.

Thermals and power in normal use

The 1.2V operating voltage limits power draw across the 768GB capacity without requiring active cooling on the modules themselves. Bare circuit boards rely on chassis airflow rather than heat spreaders to maintain stable temperatures.

Questions about this item

How much power does the 768GB kit draw at its 1.20V rating during sustained loads?

Each 128GB module operates at 1.20V, the standard DDR4 voltage, so the six-module kit draws power consistent with registered ECC memory at that voltage.

What motherboard feature is required to use these 4Rx4 registered ECC modules?

The board must support DDR4 RDIMM memory with ECC and registered buffering; consumer desktop platforms that only accept unbuffered non-ECC DIMMs will not work.

Can the 288-pin RDIMMs be mixed with existing 2Rx4 or 2Rx8 DDR4 ECC modules in the same Thinkmate server?

Mixing 4Rx4 modules with different rank architectures is not recommended; the server memory controller typically requires identical rank-per-channel configurations for stability.
