Capacity and compatibility

This 128 GB kit contains two 64 GB DDR5 4800 ECC registered DIMMs built for Thinkmate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. The modules run at PC5-38400 with CL40 latency and 1.1 V operation. They are intended for IT teams upgrading memory in those specific platforms.

Thermals and power

Each DIMM operates at the standard DDR5 voltage of 1.1 V and carries no heat spreader, relying on server chassis airflow for cooling. Registered buffering and ECC circuitry add minimal overhead while maintaining signal integrity under sustained load. Power draw scales with the 4800 MT/s data rate and 2Rx4 organisation.

Package contents and testing

The kit ships as a matched pair totalling 128 GB with no additional cables, software or accessories included. Every module undergoes stress testing under load before dispatch to verify stability and compatibility with the target Thinkmate systems. The registered ECC design corrects single-bit errors and detects multi-bit errors during operation.

Questions about this item

How do I install the 288-Pin DDR5 RDIMM modules in my ThinkMate tower server, and what step is often missed?

Power down the server, open the chassis, align each 288-Pin DDR5 RDIMM with the slot key notch, press firmly until the retention clips click, then verify in BIOS that both 64GB modules are detected at 4800MHz.

What maintenance or replacement will the 2Rx4 ECC registered DIMMs need over time?

The 2Rx4 ECC registered DIMMs have no moving parts and require no scheduled maintenance; replace a module only if memory diagnostics report uncorrectable errors or the server fails to boot with it installed.

What limit appears first when the 128GB kit runs sustained workloads at 1.10V?

The primary limit is the CL40 CAS latency at DDR5 4800 speed, which determines the minimum response time under continuous load before any thermal or voltage constraint becomes significant.
