128GB DDR5 4800 ECC RDIMM for Thinkmate Servers

This 128GB DDR5 4800 module is a registered ECC RDIMM built for Thinkmate TWX-XS8-24S4 and TWX-XS8-14S4 tower servers. It runs at 1.1V with CL40 latency and uses a 4Rx4 rank structure on a 288-pin interface. The part is designed for system-specific compatibility in enterprise environments.

Who this suits and who should look elsewhere

IT teams upgrading those exact Thinkmate towers with validated ECC registered memory will find this module fits the qualified parts list. Builders needing non-ECC UDIMMs, different capacities, other speeds, or memory for consumer motherboards or other OEM platforms cannot use this part.

The specification that decides fit

The module is a 288-pin DDR5 RDIMM with ECC and registered buffering at 4800 MT/s, CL40, 1.1V, 4Rx4 organisation, and 128GB density. Only systems whose memory controller and qualified-vendor list explicitly support this exact combination will accept it.

Questions about this item

What server platform must I already own for this 288-pin 128GB DDR5 RDIMM to be supported?

The module is validated for THINKMATE TWX-XS8-24S4 and TWX-XS8-14S4 tower servers, so one of those systems must be present for guaranteed compatibility.

How does this 4Rx4 registered DDR5 module behave alongside other registered DDR5 RDIMMs I may keep in the same chassis?

All installed DDR5 RDIMMs must run at the same 1.1V voltage and 4800 MT/s data rate; the server memory controller will configure matching timings across ranks.

How can I confirm the module is operating at its rated 4800 MT/s CL40 after installation?

Check the BIOS memory information screen or OS tools such as dmidecode to verify the reported speed shows 4800 MT/s and CAS latency 40.
