Capacity & Compatibility

This 128 GB kit contains four 32 GB DDR5 4800 RDIMM modules built for the THINKMATE GPX-XS8-24S4-4GPU workstation. Registered ECC operation with CL40 timing and 1.10 V voltage targets enterprise workloads that demand data integrity and large memory footprints.

What the kit changes

Populating all four slots with matched 2Rx8 modules delivers the full 128 GB capacity in a single validated configuration, removing the guesswork of mixing speeds or ranks. The registered buffer and on-die ECC let the platform correct single-bit errors and maintain signal quality across the 288-pin interface under sustained load.

Build & daily implications

Modules ship without heat spreaders, so airflow across the bare PCB is required inside the chassis. Each stick uses the standard 288-pin DDR5 RDIMM form factor, meaning installation follows normal server DIMM ejection-lever procedure and no proprietary tooling or clearance allowances are needed.

Questions about this item

Will the four 32 GB RDIMMs need any firmware updates or battery replacements later?

No firmware or battery maintenance is required for these DDR5 ECC RDIMMs; they operate as passive memory modules once installed.

What limit appears first when the 128 GB kit runs at 4800 MT/s continuously?

The CL40 latency and 1.1 V voltage are fixed by the module design; sustained throughput is capped by the DDR5 4800 specification.

How much heat and noise do the 288-pin registered modules produce under all-day load?

The modules have no heat spreader and no moving parts, so they add only modest heat to the chassis airflow and generate zero audible noise.
