16 GB DDR5-4800 ECC RDIMM for ThinkMate towers

This registered DIMM adds 16 GB of DDR5 memory to compatible ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. It operates at 4800 MT/s with CL40 latency and 1.10 V. ECC and register buffering protect data integrity in multi-threaded workloads.

Single-rank 1Rx8 layout leaves headroom

The 1Rx8 organisation uses one rank per module, so additional DIMMs can fill remaining slots without reducing channel density. Capacity tops out at 16 GB per module; workloads needing more memory per slot must use higher-density parts. Speed stays at DDR5-4800; faster data rates are not supported by this module.

Low-voltage operation keeps thermals modest

At 1.10 V the module draws minimal power and runs without a heat spreader in typical server airflow. Registered signalling adds negligible latency while stabilising the memory bus under sustained load. Noise and thermal output remain low in normal rack or tower environments.

Questions about this item

Will this DDR5 4800 CL40 ECC RDIMM run in a ThinkMate tower server that already has older DDR5 modules installed?

It is a 288-pin DDR5 4800 CL40 1Rx8 registered ECC module at 1.10 V; the server will clock all DIMMs to the slowest speed and loosest timings present.

How can I verify the module is operating as ECC registered memory after installation?

Check the BIOS or OS memory report — it should show 16 GB, DDR5 4800, CL40, 1Rx8, ECC enabled and registered mode active.

Does the package include only the 16 GB RDIMM or are any extra parts such as heat spreaders or cables supplied?

The box contains one 16 GB DDR5 4800 CL40 1Rx8 ECC RDIMM; no heat spreader, cables or additional accessories are included.
