768 GB ECC RDIMM kit for ThinkMate servers

This NEMIX RAM kit provides 768 GB of DDR5 4800 registered ECC memory across eight 96 GB modules. It is built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers that require 288-pin RDIMM modules with 2Rx8 organisation. The kit targets IT teams expanding memory capacity in compatible enterprise platforms.

Replaces smaller RDIMM sets when workloads exceed

The jump is worth it when virtualisation, database or analytics workloads demand more than the installed DIMM count allows and the server has eight free slots. Each module runs at 1.1 V with CL40 latency and PC5-38400 bandwidth. Buyers who need non-ECC or unbuffered DIMMs cannot use this registered ECC kit.

DDR5 4800 registered ECC limits overclocking

The registered buffer and ECC logic add latency that prevents enthusiast-style tuning, and the server platform will clock all installed modules to the slowest common speed. Modules without heat spreaders rely on chassis airflow for cooling. Systems that do not support DDR5 RDIMM at 4800 MT/s will not accept this kit.

Questions about this item

Will these 288-pin DDR5 modules fit the DIMM slots on my Thinkmate TWX-QS8-14E4 or TWX-QS8-24E4 tower server?

Yes, the kit is built for those Thinkmate tower servers and uses the standard 288-pin DDR5 RDIMM form factor their slots accept.

What is the correct way to populate all eight 96 GB modules across the CPU channels?

Follow the server manual's population table — usually fill one DIMM per channel per CPU first, then add the second rank per channel, keeping identical modules in matched slots.

When should I expect to replace a module in this 768 GB ECC RDIMM kit?

ECC corrects single-bit errors on the fly; run the platform's memory health logs and swap a module only when uncorrectable errors or persistent correctable-error thresholds are reported.
